In step S8, S9, when being judged as NO, carry out the transition to step S11, judge and check whether sequential is set to " both fixing a number ".When this is judged as YES, judge further whether this substrate P is the substrate of both having fixed a number, when being judged as YES, carry out the inspection (step S12, S13) of this substrate P.At this moment, carry out whether qualified judgement (in the example of Fig. 7, judging with inspection grade " 2 " whether installment state is qualified) according to the inspection grade that this inspection sequential (" both fixing a number ") is set.
Carry out the transition to step S14 when in step S11, S12, being judged as NO, judge and check whether sequential is set at " usually ".When this is judged as YES, carry out the inspection (step S15) of this substrate P.At this moment, carry out whether qualified judgement (in the example of Fig. 7, judging with inspection grade " 1 " whether installment state is qualified) according to the inspection grade that this inspection sequential (" usually ") is set.
And, when in step S14, being judged as NO, judging and check whether sequential is set to " usually " sequential (step S16) in addition, carries out the transition to step S6 when this is judged as YES.When it is judged as NO, make aforementioned display device 74 and warning horn (not shown) action, report makes a mistake, and stops installation check device 4 (step S17).That is,, when therefore in step S16, being NO, thinking and certain mistake takes place and circulate a notice of to give operating personnel because the setting of inspection sequential is the prerequisite that substrate is sent into.After the fault processing that operating personnel are scheduled to this circular, carry out the transition to step S2 (step S18).
After in step S4, S10, S13, S15, carrying out the inspection of substrate P, then judge check result whether qualified (step S5), when this is judged as YES, next operation is arrived in this substrate P conveyance, judge afterwards the inspection of installation check device 4 handles to move whether finish (step S6, S7).And when in step S7, being judged as NO, carrying out the transition to step S1 and send into next substrate P, process ends when being judged as YES.
On the other hand, in step S5, when being judged as NO, making the action of display 74 and warning horn with to operating personnel circular, and stop installation check device 4 (step S19, S20).These operating personnel are shown to LCD69 etc. with image, and this substrate P of visual judgement, after the operation of its result by keyboard 68 is transfused to, judge that this judges whether qualified (step S21).When this is judged as YES, carries out the transition to step S6 and next operation is arrived in this substrate P conveyance.On the other hand, when in step S21, being judged as NO, operating personnel wait for the bad alignment processing of being scheduled to, after for example this substrate being carried out mark, conveyance is to subsequent processing, perhaps make this substrate P break away from the end of the processing of production line (line out) etc., when importing the end of this processing by operating personnel, carry out the transition to step S7 (step S22) by the operation of keyboard 68.
Following simplified summary is carried out in action based on the installation check device 4 of above-mentioned control.
In this installation check device 4, check at any time whether the substrate P of sending into belongs to the substrate of the inspection sequential of in advance setting, when belonging to, carry out the inspection of this substrate P with the inspection grade that this inspection sequential is set, when not belonging to, do not check that this substrate P conveyance is to next operation.
When setting a plurality of sequential as the inspection sequential, under each sequential, check, this moment is when belonging in a plurality of inspection sequential any one when the substrate P of sending into, with the priority of " initial product ", " final products ", " both fixing a number ", " usually ", according to each inspection grade of checking that sequential is set is carried out the inspection of this substrate P.Prior applicability " initial product " " final products " the inspection inspection grade of " both fixing a number " is because require the situation of the high inspection of measure of precision more in these sequential as mentioned above.
According to aforesaid installation check device 4, by camera head 40, carry out the whether good judgement of installment state according to the shooting results (view data) of substrate P, but as mentioned above, as checking that sequential can set a plurality of sequential, and can check that sequential sets inspection grade (measure of precision) separately to each, therefore check that the degree of freedom of the sequential and the scope of examination is higher, can carry out efficient, stratified inspection, therefore can keep higher productivity, can improve the reliability of product substrate simultaneously.
Particularly, for example, can carry out efficient, stratified inspection by checking that sequential and inspection grade set in advance as shown in Figure 7.Promptly, according to this setting, by most of substrate P is simply checked (in the inspection of the looser inspection grade " 1 " of the scope internal ratio that can satisfy necessary product precision) by each substrate, can avoid substrate P frequently to unload from production line, the higher productivity that keeps substrate P, by being reached the substrate P of both having fixed a number, initial product, final products carry out accurate inspection (being the inspection of inspection grade " 2 ", " 3 "), according to its result and the tendency of alignment error at that time, can discover bad generation in advance, and take some countermeasures.Therefore; with at every turn carry out existing testing fixtures that all points check and compare with identical inspection grade, can when guaranteeing the quality of substrate P, carry out efficient, stratified inspection, consequently; can keep higher productivity, improve the reliability of product substrate simultaneously.
And in existing production line, automatic identification according to mounting points is checked all substrates with looser inspection grade, when wishing that simultaneously substrate to " initial product ", " final products ", " both fixing a number " carries out minute inspection, by visual grade this substrate is checked, but according to above-mentioned installation check device 4, comprise the situation of only " initial product ", " final products ", " both fixing a number " being carried out high-grade inspection, can carry out all inspections by the automatic identification of using camera head 40.Therefore, can make existing operating personnel's manual operation (visual examination) robotization, its result has the productive advantage that can improve substrate P.
But above-mentioned enforcement testing fixture 4 and use this device substrate P inspection method (promptly, carry out the method for the inspection of substrate P with setting content shown in Figure 7) be an embodiment of base board checking device of the present invention and substrate inspecting method, its concrete formation and method can suitably change in the scope that does not break away from purport of the present invention, for example can also adopt device as follows to constitute.
(1) in the above-described embodiment, can select the inspection grade of the different three phases of measure of precision, also can be chosen to be the inspection grade in four-stage or its above stage as the parameter relevant with the scope of examination.And, for example also can be except inspection grade with the number of checkpoint as parameter.That is, also can adopt 100% (all mounting points are checked), 70% (70% in the mounting points checked), the such parameter of 50% (50% in the mounting points checked), according to the number of checking the sequence change mounting points.In this case, also can set inspection grade and checkpoint number.
(2) in the above-described embodiment, as with check relevant four sequential of capable setting parameter " usually ", " initial product ", " final products ", " both fixing a number " of sequential, but also can be set at below three or the sequential more than five.And both having fixed a number also can be any number by the operating and setting of keyboard 68.
(3) in the above-described embodiment, when setting a plurality of sequential as the inspection sequential, priority with " initial product ", " final products ", " both fixing a number ", " usually ", and so that each inspection grade of checking that sequential is set is carried out the inspection (with reference to Fig. 8) of substrate P, also can relatively check the inspection grade that sequential sets to each, as its result, begin to check successively from the high inspection grade of grade.
(4) in the above-described embodiment, automatically check, also can in setting sequential, set the sequential that to check by manual operation with the sequential of setting.At this moment, the inspection hurdle that manual operation is used for example further is set in demonstration example shown in Figure 7, for the sequential of checking, can be admitted to the stage circular operating personnel of installation check device 4 in the substrate P that belongs to this sequential, wait is checked based on the operating personnel's of keyboard operation indication input and execution.According to this formation, can under the state that operating personnel look after, check for the inspection of specific sequential, therefore useful when the comparatively careful inspection of the visual examination that requires to comprise operating personnel.
(5) in the above-described embodiment, be provided with and check the parameter that the relevant parameter of sequential reaches and the scope of examination is relevant, operating personnel can set the combination of checking the sequential and the scope of examination arbitrarily, but the parameter of checking any one party in the sequential or the scope of examination also can only be set.Particularly, can set a plurality of inspection sequential in predetermined fixed ground, as each scope of examination of checking sequential, operating personnel can set above-mentioned inspection grade etc. arbitrarily.And, a plurality of inspection sequential can be selected arbitrarily, under the inspection sequential that operating personnel select, check according to the scope of examination that this inspection sequential predetermined fixed ground is set.Under these constitute, also can improve checking the setting degree of freedom of sequential, the scope of examination, consequently, can carry out efficiently, stratified inspection according to the content of the kind of substrate, processing.
(6) in the above-described embodiment, the example that the present invention is applicable to the installation check device 4 that the substrate P after the installation processing of erecting device 3A, 3B is checked is illustrated, and the present invention is certainly also applicable to printing inspection apparatus 2, solder attachment testing fixture 6.In this case, relevant with checking sequential parameter, the parameter relevant with the scope of examination get final product according to each device 2,6 is suitably selected.
Then second embodiment is described with reference to Fig. 9～Figure 13.
Under this second embodiment, the hookup wire that is suitable for is identical with first embodiment, constitutes as Fig. 1.
And, each testing fixture 2,4,6, though omitted diagram, but have the installation head of having carried the CCD camera and make drive unit that this installation head plane moves etc.,, carry out the inspection that each is handled according to its view data by taking the face that is mounted of substrate, particularly, in printing inspection apparatus 2, carry out the inspection of solder coating amount etc., in installation check device 4, carry out the inspection of the installation deviation etc. of parts, in reflow ovens 5, carry out the inspection of solder coating amount and parts installation deviation etc.And, inspection about the solder coating amount, check coating amount by the image recognition that is coated in the scolder on the pattern (pattern) in printing inspection apparatus 2, coating amount is checked in the image recognition of the scolder by the mounted component periphery in solder attachment testing fixture 6.
Fig. 9 is the block diagram of an example of the formation of expression central management device 8 (with reference to Fig. 1).
As shown in the drawing, central management device 8 has the control part main body 110 that is used to carry out its action control.This control part main body 110 is used to control the ROM113 of the various programs of this CPU112 etc. by the CPU112 that carries out logical operation, storage in advance, in formations such as RAM114, the HDD115 of device temporary transient store various kinds of data in service and I/O controllers (1OC) 116, these CPU112 etc. are connected to each other by internal bus.
The program used of the various application software of storage and the above-mentioned various data such as 1～6 production relevant various information, for example substrate data, parts data, printing and installation position data, reflux temperature data of respectively installing among the HDD115.And, also be stored among this HDD115 by the following inspection item of each testing fixture 2,4,6 enforcement and the data such as inspection condition of each inspection item.
Be connected with the display unit 119 that constitutes by input blocks such as keyboard, mouse 118, CRT monitor, LCD monitor on the IOC116, and be connected with and above-mentionedly respectively install 1～6, control part main body 110 receives by the predetermined indication information of the operation input of input block 118, from the various operation signals of each device 1～6, carries out the control of this management devices integral body.
And, further be provided with external memories 117 such as CD in the control part main body 110, above-mentionedly respectively install 1, the various information stores such as inspection resume of the production resume among 3A, the 3B, 5, each testing fixture 2,4,6 are in this external memory 117.For example, store the check result of each substrate in testing fixture 2,4,6 and respectively check employed substrate various fox messages such as view data, with each treating apparatus ( device 1,3A, 3B, 5) in produced mistake, keep in repair relevant information etc.
Externally in the memory storage 117 in the canned data, above-mentioned fox message sends automatically from each testing fixture 2,4,6 in the running of parts hookup wire, is stored in successively in the external memory 117 with the identifying information of each substrate.The identifying information of substrate for example is recorded on each substrate as bar code, QR sign indicating number, is read in the image recognition of the substrate in each testing fixture 2,4,6, sends to central management device 8 with check result and view data.And mistake relevant information, maintenance relevant information etc. be by being operated input block 118 input error contents, the maintenance content of respectively installing the keyboard that is provided with in 1～6 etc. by operating personnel, and send to central management device 8.
During Figure 10 constituted with the function that comprises in the block representation control part main body 110, the function of inspection condition that is used for the specific inspection item of control inspection device 2,4,6 constituted.
As shown in the drawing, comprise as the above-mentioned functions formation in the control part main body 110: master control part 121, fox message storage part 122, inspection condition changing control part 123 and display control unit 124.
Fox message storage part 122 is used to store the fox message of each testing fixture 2,4,6, particularly stores the inspection condition of inspection item and each inspection item.Figure 11 represents the inspection item of each testing fixture 2,4,6, and the inspection condition of these inspection items and each inspection item, just whether qualified judgment standard (threshold value etc.) be stored in the fox message storage part 122 as the fox message of each testing fixture 2,4,6.For example, fox message as printing inspection apparatus 2, shown in figure, storage: position deviation (position deviation of solder printing), Short Item (open printing), solder coating amount are excessively not enough, the inspection condition that inspection item and projects such as has or not of solder bridging.And, as the fox message of solder attachment testing fixture 6, storage: position deviation (position component deviation), Short Item (no parts), solder coating amount are excessively not enough, the having or not of solder bridging, inspection condition that polarity is judged (incorrect polarity), mistake parts inspection items such as (parts mistakes) and projects.
Can change the inspection condition of setting value or change the inspection condition of setting value according to the command signal of following inspection condition changing control part 123 for the operation by operating personnel in the inspection condition, present setting value is stored in the fox message storage part 122 with the initial value of the condition of inspection.
Check condition changing control part 123, inspection item for common or being interrelated property, judge the contradiction that has or not check result between solder attachment testing fixture 6 and other each testing fixtures 2,4, when having contradiction, output instruction signal, with the inspection condition that this inspection item that changes for printing inspection apparatus 2 or installation check device 4 sets, printing inspection apparatus 2 and installation check device 4 change the inspection condition of setting according to this command signal.And, " common or related inspection item " is meant, owing to check that object is identical, thereby a side check result and the opposing party's check result is in the inspection item of consistent relation usually, though check perhaps that object is different but check relevant property between the object, both sides' check result is in the inspection item of concord usually.
In this embodiment, inspection item as relevant property, for " excessive not enough inspection of solder coating amount ", judge that according to printing inspection apparatus 2 and solder attachment testing fixture 6 both sides' check result noncontradictory is arranged, when having contradiction, from checking that condition changing control part 123 is to printing inspection apparatus 2 output instruction signals, to change the inspection condition that this inspection item is set, particularly, inspection condition as " excessive not enough inspection of solder coating amount ", in printing inspection apparatus 2, be set at " area tolerance (initial value): 50%～150% ", when producing contradiction in the check result, to printing inspection apparatus 2 output instruction signals, so that this tolerance increase and decrease changes predetermined fixed value.And, as common inspection item, for " inspection of (parts) position deviation ", judge that according to installation check device 4 and solder attachment testing fixture 6 both sides' check result noncontradictory is arranged, when having contradiction, to installation check device 4 output instruction signals, to change the inspection condition of this inspection item.Particularly, inspection condition as " (parts) position deviation ", in installation check device 4, be defined as " position deviation tolerance (initial value) :+0.2mm～-0.2mm ", when producing contradiction in the check result, output instruction signal is so that this tolerance increase and decrease changes predetermined fixed value.
And in this embodiment, this inspection condition changing control part 123 is equivalent to judging unit of the present invention and condition changing unit.
Then, the example that the action of the 110 pairs of inspection conditions of above-mentioned control part main body management (changes) is controlled describes with reference to the process flow diagram of Figure 12.And in following process flow diagram, for " inspection of (parts) position deviation " in the above-mentioned inspection item, just the situation of the inspection condition of management (change) installation check device 4 describes, afterwards, for inspection item " excessive not enough inspection of solder coating amount ", just manage the situation of the inspection condition of printing inspection apparatus 2 and replenish.
This process flow diagram begins by in the parts hookup wire check result of solder attachment testing fixture 6 being sent to central management device 8.
In solder attachment testing fixture 6, check and finish, after the check result of this substrate sends to central management device 8, at first, in step S101, the check result of each testing fixture 2,4,6 of this substrate is read into checks condition changing control part 123, carry out the comparison of the check result of front/rear operation.That is, the check result of inspection item " inspection of (parts) position deviation " in each testing fixture 2,6 compared, in checking condition changing control part 123, judge whether two check results do not have contradiction (step S102).At this, process ends figure when being judged as YES.
On the other hand, when in step S102, being judged as NO, comprise this substrate, substrate to predefined regulation number judges whether to produce continuously contradiction (step S103) in check result, further judge whether to surpass predefined requirement ratio (for example each batch is 10%) and produce above-mentioned contradiction (step S104) this moment when being judged as NO.And, when this is judged as NO, process ends figure.
Relative with it, when in step S103, S104, being judged as YES, carry out the transition to step S105, from checking that condition changing control part 123 is to installation check device 4 output instruction signals, change the inspection condition (parameter is from normal moveout correction) of this inspection item (" inspection of (parts) position deviation ") of installation check device 4, and the inspection condition after will changing stores above-mentioned fox message storage part 122 into.
Particularly, when the check result of solder attachment testing fixture 6 is that " qualified " judged, when the check result of installation check device 4 is " defective " judgement, from the result, think that the inspection condition of installation check device 4 is too strict, in this case, make the upper lower limit value of position deviation tolerance enlarge setting (for example 0.05mm), so, the position deviation tolerance is changed into "+0.25mm～-0.25mm ", this tolerance is stored in the fox message storage part 122 as present inspection condition with upgrading.
On the other hand, the check result of solder attachment testing fixture 6 is that " defective " judged, when the check result of installation check device 4 is " qualified " judgement, from the result, think that the inspection condition of installation check device 4 is comparatively loose, therefore in this case, make the upper lower limit value of position deviation tolerance dwindle 0.05mm, make the position deviation tolerance change into "+0.15mm～-0.15mm ", and store this tolerance into fox message storage part 122 as present inspection condition with upgrading.
After in step S105, finishing the change of inspection condition like this, process ends figure.
More than at " inspection of (parts) position deviation ", control during the inspection condition of management (change) installation check device 4, but, also, manage the inspection condition of (change) printing equipment 2 by carrying out identical with it processing simultaneously for " the solder coating amount is excessively not enough to be checked ".
At this moment, the concrete processing of step S105 is as follows.At first, when the check result of solder attachment testing fixture 6 is that " qualified " judged, when the check result of printing inspection apparatus 2 is " defective " judgement, from the result, think that the inspection condition of printing inspection apparatus 2 is too strict, therefore in this case, check result according to solder attachment testing fixture 6 is the defective judgement that " insufficient solder connection " causes, still " scolder is too much " defective judgement of causing increases and decreases the upper lower limit value of position deviation tolerance respectively to change setting (for example 2%).Particularly, when defective judgement that being judged as of printing inspection apparatus 2 " insufficient solder connection " causes, the lower limit of area tolerance is descended 2%, the area tolerance of solder printing is changed into " 48%～150% ", when the defective judgement that causes for " scolder is too much ", the higher limit of area tolerance is improved 2%, the area tolerance of solder printing is changed into " 50%～152% ".
On the contrary, when the check result of solder attachment testing fixture 6 is that " defective " judged, when the check result of printing inspection apparatus 2 is " qualified " judgement, from the result, think that the inspection condition of printing inspection apparatus 2 is comparatively loose, therefore in this case, make the upper lower limit value increase and decrease of area tolerance change 2%.Particularly, when defective judgement that being judged as of solder attachment testing fixture 6 " insufficient solder connection " causes, the lower limit of area tolerance is improved 2%, the area tolerance of solder printing is changed into " 52%～152% ", when the defective judgement that causes for " scolder is too much ", the higher limit of area tolerance is descended 2%, the area tolerance of solder printing is changed into " 50%～148% ".And, store this tolerance that changes into fox message storage part 122 as present inspection condition with upgrading.
Control according to this control part main body 110, for example to " inspection of (parts) position deviation ", when the check result of contradiction appears in installation check device 4 and 6 of solder attachment testing fixtures, processing by step S105 changes the position deviation tolerance, afterwards, according to the position deviation tolerance after this change, in installation check device 4, implement " inspection of (parts) position deviation ".And, when the check result of contradiction still occurring after this processing, by the condition (being YES among step S103, the S104) that satisfies step S103, S104, the position deviation tolerance is changed once more, so, till check result contradiction is eliminated, change the position deviation tolerance repeatedly with setting at every turn.And,, when the check result of contradiction appears in printing equipment 2 and 6 of solder attachment testing fixtures, handle too for " solder coating amount excessively not enough check ".
Parts hookup wire according to above explanation, between printing inspection apparatus 2 or installation check device 4 and solder attachment testing fixture 6, for " the solder coating amount is excessively not enough to be checked ", " inspection of (parts) position deviation " common or related like this inspection item, when the check result of contradiction with more than to a certain degree during frequent the generation, the inspection condition of this inspection item of printing inspection apparatus 2, installation check device 4 is increased and decreased with fixed value, and the check result that can eliminate contradiction thus automatically continues the situation of generation.
Therefore, need not to carry out complicated operations as follows: for common or related inspection item as existing this parts hookup wire, when the check result of contradiction between testing fixture, occurring, determine the testing fixture, inspection item, the inspection condition that conflict respectively by operating personnel, change the inspection condition of this inspection item simultaneously by manual operation.And can eliminate original unnecessary defective judgement in early days, its result can more successfully advance the production of substrate.
And, the change of aforesaid inspection condition is (among the step S103 of Figure 12, the S104 for YES time) that implements when satisfying following at least one side's condition: the contradiction that the check result of the substrate of continuous regulation number produces contradiction or check result surpasses the ratio of stipulating and takes place, although so the contradiction that can avoid check result is the momentary contradiction because of generations such as image recognition errors, but the inspection condition still situation of unhelpful change takes place, thereby can keep the reliability checked well.
And above-mentioned parts hookup wire is an embodiment that has been suitable for the parts hookup wire of inspection condition management system of the present invention, but it specifically is formed in appropriate change in the scope that does not break away from purport of the present invention.It for example can be formation as described below.
(1) in embodiment, in the inspection item of in each testing fixture 2,4,6 of parts hookup wire, implementing, with " inspection of (parts) position deviation " and " excessive not enough inspection of solder coating amount " is example, for this inspection item, the situation of just managing the condition of respectively checking of printing inspection apparatus 2 and installation check device 4 is illustrated, certainly for the inspection item beyond it, also applicable the present invention during the inspection condition of managing each testing fixture 2,4,6.For example for inspection item shown in Figure 11, " inspection of (parts) position deviation ", " excessive not enough inspection of solder coating amount " project in addition are also as shown in the figure, in a plurality of testing fixtures 2,4,6, implement, therefore also can be for any one the management printing inspection apparatus 2 in these inspection items, the inspection condition of installation check device 4.
(2) in embodiment, when the check result of contradiction occurring, by the inspection condition of setting in printing inspection apparatus 2 or installation check device 4 (tolerance) is increased and decreased with predetermined fixed value, condition is checked in setting capable of automatic changing, for example its constitute also can for, do not check the change of condition, the information such as contradiction testing fixture 2,4, inspection item, check result and inspection condition that only will produce are shown to display unit 119, show that according to this information operating personnel change the inspection condition (setting tolerance) of each testing fixture 2,4 by manual operation.
So, the change operation of inspection condition is undertaken by manual operation, but operating personnel can promptly determine to produce the testing fixture, inspection item, inspection condition etc. of contradiction according to the demonstration of display unit 119, therefore go up in this point (can promptly carry out this definite this point) and compare, can promptly take measures when in check result, producing contradiction with existing this device.And under this constitutes, by reference check result etc., operating personnel can change into value arbitrarily with inspection condition (tolerance), therefore have the following advantages: for example because of the input error of checking condition etc., in the time of need significantly correcting the setting inspection condition of printing inspection apparatus 2, installation check device 4, can promptly dispose.
(3) when check result produces contradiction, also not necessarily because the inspection condition of setting is incorrect, therefore in this case, can implement the processing of step S110 shown in Figure 13～S113 sometimes, replace the processing of the step S105 in the process flow diagram of Figure 12.
That is, when in step S103, S 104, being judged as YES, carry out the transition to step S110, at this change of judging the inspection condition whether appropriate (step S110).When this is judged as YES, carry out the transition to step S113, change the inspection condition.And the contents processing of this step S113 is the identical contents processing of processing with the step S105 of Figure 12.
On the other hand, when being judged as NO in step S110, will have inspection item of possibility etc., the information such as testing fixture, inspection item, inspection condition that promptly produces contradiction is shown to display unit 119 (step S111).And, for this demonstration, for example after operating personnel have carried out measures necessary, judge whether this operation finishes, particularly, judge the input operation (step S112) that has or not input block 118, when being judged as end, process ends figure.
According to this control, when check result produced contradiction, in order to eliminate this contradiction, therefore will that can the interventional procedure personnel was applicable to the uncertain situation of reason etc. of the contradiction of check result.
Particularly, in the common inspection item " solder bridging inspection " (with reference to Figure 11) of printing inspection apparatus 2 and solder attachment testing fixture 6, be that the check result of qualified judgement solder attachment testing fixture 6 is the situation of defective judgement though there is the check result of printing inspection apparatus 2.At this moment, except the unsuitable situation of inspection condition of printing inspection apparatus 2, the unsuitable possibility of pressure of the parts when parts are installed is also higher, therefore for this inspection item, in step S110, be judged as NO, will exist possible project, the i.e. demonstration of " solder bridging inspection " to be shown to display unit 119 (step S111) with information such as its check result, inspection conditions.
So, operating personnel can be in erecting device 3A, 3B whether the pressure of inspection part suitable substantially, and do not have the inspection condition that changes printing inspection apparatus 2 when unusual.Therefore, can effectively avoid the pressure of the parts among no matter erecting device 3A, the 3B whether incorrect, all change the problem of the inspection condition of printing inspection apparatus 2, can reasonably eliminate the contradiction reason.
Wherein, is that example is illustrated as inspection item with " solder bridging inspection ", for inspection item in addition, former for the contradiction of check result because the project of other (beyond checking that condition enactment is inappropriate) reasons, in step S110, be redefined for and make NO and judge, make operating personnel's will to get involved and get final product.
(4) in embodiment, between printing inspection apparatus 2 or installation check device 4 and solder attachment testing fixture 6, when producing contradiction in the check result, check result with solder attachment testing fixture 6 be as the criterion (as benchmark), change is as the inspection condition of printing inspection apparatus 2 grades of the inspection of its preceding operation, and this is because the inspection after the reflow treatment is the inspection of terminal stage, its condition is generally compared comparatively strict with printing inspection apparatus 2 grades, higher with the reliability of check result is prerequisite.Therefore, when the inspection grade (measure of precision of inspection) of printing inspection apparatus 2 grades and solder attachment testing fixture 6 when not having difference, also can change the inspection condition of solder attachment testing fixture 6,, get final product according to suitable settings such as concrete inspection items as for which check result to be benchmark with.
And, in embodiment, for common or related inspection item between printing inspection apparatus 2 or installation check device 4 and the solder attachment testing fixture 6, the situation that produces contradiction in the check result is illustrated, applicable too the present invention when check result produces contradiction between printing inspection apparatus 2 and installation check device 4 certainly, in this case, which check result to be that benchmark gets final product according to suitable settings such as concrete inspection items with.
(5) in embodiment, central management device 8 is set on the parts hookup wire, fox message storage part 122 is set on its control part main body 110, checks condition changing control part 123, reaches display control unit 124 etc., but for example also these functions can be constituted the control device that is arranged at solder attachment testing fixture 6, the contradiction judgement of check result, the processing such as change instruction of inspection condition are carried out in solder attachment testing fixture 6.
(6) in embodiment, upstream side at erecting device 3A, 3B, as paste coating apparatus configuration solder printing device 1, testing fixture configuration printing inspection apparatus 2 as its processing, also can be used as paste coating apparatus configuration point gum machine, as the testing fixture configuration coating testing fixture of its processing.
(7) each testing fixture 2,4,6 also can be respectively formation as follows.
1. printing inspection apparatus
In embodiment, printing inspection apparatus 2 independently is arranged between solder printing device 1 and the erecting device 3A, but also can with solder printing device 1 integrated (for example one is assembled into the substrate submitting portion of solder printing device 1), perhaps with the erecting device 3A of a last operation side integrated (for example the one substrate that is assembled into erecting device 3A is sent into part).At this moment, when adopting the formation of above-mentioned (6), also be identical certainly to the coating testing fixture.
2. installation check device
In embodiment, two common installation check devices 4 of erecting device 3A, 3B are arranged between the erecting device 3B and reflow ovens 5 of subsequent processing side independently, but also can special-purpose installation check device be set to each erecting device 3A, 3B.
Promptly, between the erecting device 3B (for being called the second erecting device 3B for simplicity) of erecting device 3A of a last operation (for being called the first erecting device 3A for simplicity) and subsequent processing, separate configurations is used to check the installation check device (for being called the first installation check device 4A for simplicity) of the substrate after the first erecting device 3A handles, between the second erecting device 3B and reflow ovens 5, separate configurations is used to check the installation check device (for being called the second installation check device 4B for simplicity) of the substrate after the second erecting device 3B handles.And, when as mentioned above each erecting device 3A, 3B being provided with the installation check device, the first installation check device 4A, also with the incorporate device of the first erecting device 3A (for example one is assembled into the device of the substrate submitting portion of the first erecting device 3A) or with the incorporate device of the second erecting device 3B (for example the one substrate that is assembled into the second erecting device 3B is sent into part).Equally, for the second installation check device 4B, can be with the incorporate device of the second erecting device 3B (for example one is assembled into the substrate submitting portion of the second erecting device 3B) or with reflow ovens 5 incorporate devices (for example the one substrate that is assembled into reflow ovens 5 is sent into the device of part).
