Description

In the printed circuit board (PCB) manufacture controller in order to the decision position of positioning hole method
Technical field
The present invention relates to printed circuit board (PCB) (Printed Circuit Board; Be called for short PCB) manufacturing process, particularly relate to the method in the manufacture controller of printed circuit board (PCB) in order to decision pilot hole (Pin Holes) position.
Background technology
Printed circuit board (PCB) is according to circuit design, and the electric wiring of connecting circuit part is depicted as wiring figure, and then in modes such as the machining of designing institute appointment, surface treatments, makes electric conductor reappear the circuit board that is constituted on insulator.In other words, printed circuit board (PCB) promptly is meant collocation electronic component substrate before.
The mutual electric current that the major function of printed circuit board (PCB) provides top every part connects, and bringing into play the function of every electronics spare part, and realizes the purpose of signal Processing.Along with electronic equipment becomes increasingly complex, the part that needs is more and more, and PCB the higher authorities' circuit and part are also more and more intensive.Therefore, the height of PCB design quality not only directly influences the fiduciary level of electronic product, but the also performance of left and right sides system product integral body and competitive power.
The manufacturing process of general printed circuit board (PCB) can comprise in regular turn: multilayer board internal layer circuit, multilayer board pressing, boring, through hole copper facing, outer-layer circuit, secondary copper facing, anti-welding green lacquer, text printout, gold-plated, spray tin, moulding and manufacturing process such as inspection eventually.Wherein for example boring and the moulding manufacturing process before, must utilize pin (Pin) to penetrate printed circuit board (PCB) earlier, printed circuit board (PCB) is fixed on the backboard of a platform or mould, just hole or the moulding program.
Figure 1 shows that backboard and printed circuit board (PCB) synoptic diagram, general pilot hole boring is as described below with the pin fixing step.Please refer to Fig. 1, at first, printed circuit board (PCB) 20 is seated on the backboard 10 of boring board or moulding board.Then, controller can form pilot hole 22 simultaneously according to the position of setting on printed circuit board (PCB) 20 and backboard.Afterwards, again pin (not shown) is passed pilot hole 22, so that printed circuit board (PCB) 20 is fixed on the backboard 10.
General backboard 10 can be made of the bakelite material, and keeps its fixed position because printed circuit board (PCB) runs through printed circuit board (PCB) 20 by pin with backboard 10, is can't be reusable so formed the used position of old pilot hole on the backboard 10.For instance, if have the left old vestige that comes several pilot holes 12 of manufacturing process last time on the backboard 10, then the position of each pilot hole 22 all can not be repeated with the position of old pilot hole 12 on the printed circuit board (PCB) 20, otherwise the pin of subsequent fixed may move and make that the stationkeeping of printed circuit board (PCB) 20 is bad, and causes the mistake of follow-up boring or moulding program.
The size of backboard is generally greater than printed circuit board (PCB), and prior art all utilizes trial and error pricing and manual detection to decide the position of printed circuit board (PCB) on backboard, overlaps to avoid new position of positioning hole on the printed circuit board (PCB) and the old position of positioning hole on the backboard.So-called trial and error pricing and manual detection, for instance, on the backboard of not placing printed circuit board (PCB), board can carry out a test drilling step according to predefined new position of positioning hole on backboard earlier, so, make and leave a trace extremely shallow but the cognizable new position of positioning hole of naked eyes on the backboard 10.
Then, utilize manually the position of differentiating new pilot hole on the backboard with naked eyes whether to overlap on the old pilot hole on the backboard 10 again.If above-mentioned new position of positioning hole and old position of positioning hole are overlapping, then select other printed circuit board (PCB) offset distance value to obtain other new position of positioning hole again, repeat above-mentioned test drilling afterwards again and check step, up to determining that the new position of positioning hole on the backboard is not overlapping with old position of positioning hole, just carry out formal pilot hole boring step.
Generally can be easy to avoid old position of positioning hole on it and determine printed circuit board (PCB) rapidly without use or the few backboard of access times.But, after the use of certain number of times of backboard process,, manually can not determine suitable offset distance easily in order to using by having too much use location thereon, and must just can make all new pilot holes not overlapping through test drilling test repeatedly with old pilot hole.Perhaps, because manually-operated personnel's operating experience difference, when having too many shallow pilot hole vestige on the backboard, more inexperienced operating personnel not only waste the too many time easily and are differentiating on the position of positioning hole, and can't determine correct offset distance.In addition,, in the time manually can't positioning the hole site differentiation, just must carry out the replacing of backboard, so can make the utilization rate of backboard reduce and the manufacturing cost of increase printed circuit board (PCB) though still have not use location on the backboard.
In above-mentioned prior art, avoid used position on the backboard with manually-operated and trial and error pricing, can not obtain the high usage ratio of effective time control and backboard, so cause the manufacturing cost of printed circuit board (PCB) to increase.
Summary of the invention
At above-mentioned the deficiencies in the prior art, purpose of the present invention is for providing a kind of system in order to the decision position of positioning hole, be applied in the manufacture controller of printed circuit board (PCB), utilize judge module and arithmetic unit, see through stored the processing and the position of positioning hole data of will process of storage device, and avoid used position on the backboard automatically, and obtain new offset distance.So, the use of backboard is subjected to the control of robotization, with previous operations time of shortening printed circuit board (PCB) and obtain higher backboard utilization rate.
According to above-mentioned purpose, the present invention comprises in order to the system of decision position of positioning hole: a storage device, in order to store new pilot hole and the old positioning hole data that is positioned on the backboard; One arithmetic unit and a judge module, wherein arithmetic unit is by obtaining new pilot hole and old positioning hole data in the storage device, and utilize a location boring ratio that method is carried out one first comparison step by judge module, in order to inspect the position of new pilot hole, if judge module is judged arbitrary position of new pilot hole and is not met the condition of the first comparison step, then carry out recomputating step by arithmetic unit, obtain an offset distance value and the position of the new pilot hole of emulation on backboard, to repeat the first comparison step in the substitution judge module, if judge module is judged the position of all new pilot holes and is all met the condition of the first comparison step, then finishes comparison.
Above-mentioned pilot hole comparison method comprises: utilize arithmetic unit to calculate the distance in the old pilot hole center of circle and the new pilot hole center of circle earlier, and calculate a limiting distance, wherein limiting distance is the radius that the radius of old pilot hole adds new pilot hole; Then, utilize discrimination module to judge that whether the distance in the old pilot hole center of circle and the new pilot hole center of circle is less than limiting distance, if the distance in the old pilot hole center of circle and the new pilot hole center of circle, is then judged new position of positioning hole less than limiting distance and is not met the condition of pilot hole comparison method.For shortening comparison time, can be set in an effective ratio earlier the old pilot hole in the scope is just carried out above-mentioned pilot hole comparison method.This effective ratio is that the length of side equals that the radius of maximum old pilot hole adds the new pilot hole radius of being compared on the backboard to scope definition, perhaps adds the permissible error value and the square area that constitutes.
In addition, also be in order to shorten comparison time, can before above-mentioned pilot hole comparison method, to carry out another more rough comparison step, block density comparison method for example of the present invention.If judge module is judged arbitrary position of new pilot hole and is not met the condition of above-mentioned another comparison step that then arithmetic unit can recomputate step and repeat above-mentioned another comparison step by judge module.And, if judging the position of new pilot hole, judge module all meets the condition of above-mentioned another comparison step, then just proceed aforesaid pilot hole comparison method.And, because the adding of above-mentioned another comparison step, then do not meet pilot hole comparison method and recomputate the new pilot hole of step, also need begin to compare again by above-mentioned another comparison step earlier.
Block density comparison method of the present invention comprises: arithmetic unit is several blocks with the backboard virtual dividing earlier, and calculates the density of block separately of these blocks; Then, arithmetic unit definition one restriction block density; If the block density of arbitrary block that includes new pilot hole is greater than restriction block density, then judge module judges that the position of new pilot hole does not meet the condition of block density comparison method; And if the block density of all blocks that comprises new pilot hole is all less than restriction block density, then judge module judges that the position of new pilot hole meets the condition of block density comparison method.Wherein, above-mentioned block density is represented in the single block, and the summation area of the pilot hole of haveing been friends in the past is than the ratio of last single block area.
Use method of the present invention, the position of positioning hole that can manage on the backboard automatically to be determined, operating personnel need only process according to the deviation post that method is advised, and do not need to carry out trial and error pricing processes such as for example test drilling as prior art, can avoid the use location on the backboard.And see through effective management of controller, can avoid operating personnel to neglect or lack experience and the shortcoming that causes the backboard utilization rate to descend.According to above-mentioned advantage, method of the present invention can reduce time and the consumables cost that printed circuit board (PCB) is made simultaneously.

Embodiment
The present invention discloses in a kind of printed circuit board (PCB) manufacture controller the method in order to the decision position of positioning hole, and is more detailed and complete in order to make narration of the present invention, can be with reference to the diagram of following description and cooperation Fig. 2 to Fig. 6.
Figure 2 shows that in the printed circuit board (PCB) manufacture controller of the present invention preferred embodiment process flow diagram in order to the method for decision position of positioning hole, implement method of the present invention and comprise a storage device, an arithmetic unit and a judge module at least, carry out the explanation of the inventive method with this preferable enforcement and operating process in this present invention.Please refer to Fig. 2, at first pilot hole work procedure 50 in the opening controller by taking out several data in the storage device, is put down in writing old positioning hole data of having holed and the new positioning hole data that will hole in these data.Then, arithmetic unit can read above-mentioned data, finds out the position of positioning hole of the step of will holing, Here it is so-called procedure simulation 52.And arithmetic unit also calculates the maximum distribution scope 54 of pilot hole and obtains the offset distance value 56 that originally set in the pilot hole work procedure except finding out the position of positioning hole of holing.
Wherein, above-mentioned maximum distribution scope 54 is meant the maximum distribution district of pilot hole, needs not be equal to the area size of printed circuit board (PCB).In addition, the offset distance value 56 that arithmetic unit calculated just is recorded in the above-mentioned pilot hole work procedure 50 originally, and is specified by the program designer.And the offset distance value of indication in the present invention, the standoff distance of another position of certain some position and backboard on the finger mark printed circuit board, and the appointment reference point on these printed circuit board (PCB)s and the backboard all can be defined voluntarily by operating personnel, the invention is not restricted to this.And the present invention does not limit and must give arithmetic unit one offset distance value at the very start.
Above-mentioned steps 50 to step 56 obtains the process of positioning hole data for normal controller, and should be those skilled in the art and know, and does not give unnecessary details so the present invention does not do at the method for above steps and calculating.And, increase or delete above-mentioned steps or utilize other flow process and obtain pilot hole related datas such as maximum distribution scope and first offset distance value that all can continue to be applied in the present invention's method described later, the present invention is not limited to this.
Obtain the maximum distribution scope and new and old positioning hole data of pilot hole when arithmetic unit after, then, judge module will carry out the comparison of new position of positioning hole and old position of positioning hole.If new position of positioning hole and old position of positioning hole repeat, then method is just created a loop, recomputates other offset distance value with in the substitution discriminating step, till the position of new pilot hole is eligible to make arithmetic unit according to predetermined rule.In preferred embodiment of the present invention, make judge module carry out more rough block density comparison method 58 earlier and judge whether new position of positioning hole is eligible.If new position of positioning hole do not meet block density comparison method 58 fixed condition, then arithmetic unit can recomputate new offset distance value 60, carries out the comparison step that block density is compared method 58 again.
If new position of positioning hole meet block density comparison method 58 fixed condition, then judge module can be again according to than the precise positioning boring ratio method 62 being compared.Similarly, if new position of positioning hole do not meet pilot hole comparison method 62 fixed condition, then arithmetic unit can recomputate new offset distance value 60, comes back to the comparison step that block density is compared method 58 again.And for example the new position of positioning hole of fruit meet pilot hole comparison method 62 fixed condition, promptly finish pilot hole comparison 64, represent new position of positioning hole not overlapping with old position of positioning hole, can make board carry out formal boring step.
General judge module utilizes pilot hole comparison method can confirm whether the position between two pilot holes is overlapping, but can increase the processing time of system because the number of new pilot hole and old pilot hole is numerous, therefore, in the above-mentioned preferred embodiment of the present invention, it is close to the comparison method to increase by one block before pilot hole comparison method, can delete the scope of invalid block earlier roughly, and speed the distinguishing speed of system.It should be noted that the visual manufacturing process of operating personnel needs and before pilot hole comparison method, other comparison method of increase or step the invention is not restricted to this in judge module.
Be illustrated in figure 3 as the synoptic diagram of the backboard of using block density comparison method, old pilot hole and new pilot hole.Please refer to Fig. 3, have many old pilot holes 102 positions on the backboard 100, shown in the soft dot among Fig. 3.At first, according to specific dimensions, virtual dividing is several square block of cells to arithmetic unit with the area of backboard 100.In addition, the new pilot hole of several of printed circuit board (PCB) 112 positions also can according to former deviation post by arithmetic unit emulation on backboard 100, shown in the round dot that has oblique line among Fig. 3, and the square that surrounds all new pilot hole 112 positions is represented the maximum distribution scope 110 of several new pilot hole 112 positions.
And so-called block density comparison method supposes that exactly single block area is A C, and the shared summation area of new and old pilot hole is A in this block H, and arithmetic unit can calculate the block density A of each block H/ A CValue, and set A H/ A CA restriction proportion, for example about 70%.Then, judge module can be compared the A of new pilot hole 112 place blocks one by one H/ A CRatio detects the A of all new pilot hole 112 place blocks H/ A CWhether ratio is less than 70%.
Referring again to Fig. 4, the block area that the present invention will comprise the 5*5 of maximum distribution scope 110 amplifies.Wherein new pilot hole 112a is positioned at the junction of four blocks, so judge module must comprise the block of new pilot hole 112a position at all, that is shown in the point-like scope of 2*2 block among Fig. 4, carries out A H/ A CThe affirmation of ratio.If the A of 5*5 block among Fig. 4 H/ A CRatio then represents new pilot hole 112 positions by block density comparison method all less than 70%, can proceed next comparison step.
But in the process of above-mentioned block density comparison method, judge module is in case find to have the A of arbitrary pilot hole 112 place blocks H/ A CRatio is greater than 70%, then representing the distribution range of new pilot hole 112 to have drops in the block that can't use, do not need to carry out again the block density comparison of other new pilot hole, must seek new offset distance and emulation position in addition, carry out the position comparison again by judge module again by arithmetic unit.Perhaps, operating personnel can be set in after judge module finishes the block comparison that comprises new position of positioning hole to some extent, differentiate the existence whether invalid block (block density is greater than 70%) is arranged again,, the invention is not restricted to this to carry out the new offset distance of subsequent calculations or to carry out next comparison step.
Wherein above-mentioned 70% maximum A H/ A CRestriction proportion is only for for example, and operating personnel can optionally and voluntarily define, and operating personnel more can define the definition rule of block density voluntarily, the invention is not restricted to this.
Judge module then positions boring ratio to method after finishing block density comparison method.Figure 5 shows that the effective ratio of using pilot hole comparison method is to the scope synoptic diagram.Please refer to Fig. 5, so-called pilot hole comparison method is the center by arithmetic unit with new pilot hole 112b earlier, there to be maximum old pilot hole aperture L on the whole back plate 1, add the radius L of the new pilot hole 112b at above-mentioned center 2, add comparison permissible error value q 1, set so formed square region scope as effective ratio to scope 130.Then, all are dropped on effective ratio to the old position of positioning hole in the scope 130, to carry out overlap ratio right with the pilot hole 112b at center.
And so-called overlap ratio is right, utilize earlier two distance of center circle that arithmetic unit calculates old pilot hole and new pilot hole from one limit distance, be L to the radius of the old pilot hole of scope 130 wherein if hypothesis is arranged in effective ratio 3, the radius that then limits distance value and be old pilot hole is L 3The center that adds new pilot hole 112b radius L 2Add permissible error value q 2Then, utilize again two distance of center circle that judge module judges old pilot hole and new pilot hole from, whether less than above-mentioned qualification distance value (L 3+ L 2+ q 2).If two distance of center circle of old pilot hole and new pilot hole are from less than (L 3+ L 2+ q 2) the qualification distance value, judge that then the position of above-mentioned new pilot hole 112b and old pilot hole are overlapping, that is new position of positioning hole is ineligible, must recomputate new offset distance by arithmetic unit, carry out block density comparison method by judge module again.
Wherein, above-mentioned permissible error value q 1With permissible error value q 2All can look manufacturing process or product needed and set up on their own by operating personnel.
In addition, please refer to Fig. 6, Figure 6 shows that and use the synoptic diagram that spiral method decides new pilot hole offset direction.In a preferred embodiment of the present invention, be used as calculating the reference of offset distance with spiral method.Position X wherein 1Represent original position of the reference point of aforementioned printed circuit board (PCB), when judge module judged that new position of positioning hole does not meet the condition of aforementioned comparison method, then arithmetic unit can be turned right new pilot hole skew one distance earlier to position X 2The line data of going forward side by side calculates, and carries out the condition comparison again by judge module again.If again ineligible, then according to as shown in Figure 6 direction deviation post X in regular turn 3, X 4, X 5, X 6, X 7, X 8, X 9With X 10Or the like, compare again.It should be noted that among Fig. 6 each position and distance thereof only for for example, operating personnel can use clockwise or anti-clockwise spiral method voluntarily, recomputate offset distance.
In addition, the distance between each position can be according to the incongruent condition of new pilot hole, and different account forms is arranged, and operating personnel can define the computation rule of arithmetic unit voluntarily, and the present invention is not limited to this.
According to a preferred embodiment of the present invention, if new pilot hole does not meet the condition of block density comparison method, then arithmetic unit can be made the offset direction according to spiral method, and calculate and in all invalid blocks, can make new pilot hole shift out the maximum offset of invalid block, this is the distance between the two positions in the above-mentioned spiral method.But arithmetic unit can be added above-mentioned maximum offset former offset distance before as new offset distance value, the process of comparing again again.
Perhaps, if new pilot hole is the condition that does not meet pilot hole comparison method, then arithmetic unit is made the offset direction except the foundation spiral method, and can calculate and can make overlapping new pilot hole move on to the outer required amount of movement of safe range, and this is the distance between the two positions in the above-mentioned spiral method.But the former offset distance before arithmetic unit also can be added above-mentioned amount of movement automatically is with the process of comparing again as new offset distance value.
Through behind the above-mentioned comparison method, if all new position of positioning hole not only meet block density comparison method and meet pilot hole comparison method, then can confirm new position of positioning hole not with backboard on institute's position of positioning hole of haveing been friends in the past overlapping, finished the comparison step to this.Then, the final offset distance value that can utilize arithmetic unit to advise is carried out drilling program.And except the position of positioning hole in the formal drilling program can be stored in the storage device, arithmetic unit more can recomputate each block density, and is stored in synchronously in the storage device, the reference data with as next position of positioning hole emulation the time.
Because above-mentioned general pilot hole manufacturing process carried out before boring step or forming step, therefore can with the present invention in order to the system applies of decision position of positioning hole in the controller of drilling machine or make-up machine, but the present invention is not limited to the controller of above-mentioned drilling machine or make-up machine.
Utilize system of the present invention and controller, can manage pilot hole automatically and must not use trial and error pricing and manually seek suitable offset distance value, and compare according to new and old positioning hole data automatically by system, overlapping if any new and old pilot hole, then system can produce the offset distance value that is fit to automatically.And system also can manage positioning hole data automatically, can add up backboard institute used location hole count, and these data can be decided in its sole discretion by operating personnel and keep or removing.
Because all processes are managed automatically by the system of controller, therefore can shorten the manufacturing time of printed circuit board (PCB).Therefore and the use of backboard and offset distance value all can be come unified management by system, can improve the utilization rate of backboard and reduce consumables cost.Thus, will help the manufacturing of printed circuit board (PCB), and improve the competitive power of electronic product.
