The present invention solve technical problem technical solution be:On the one hand, the embodiment provides a kind of pcb board is clear Clean method, includes the following steps,
One, pcb board to be cleaned is placed in fixed fixture;
Two, all tin creams of pcb board plate face are removed;
Three, using the residual tin cream on dust-free paper wiping pcb board;
Four, pcb board is taken out, is blown clean the residual tin cream on pcb board in hole etc. with air gun;
Five, the pcb board after visual inspection cleaning, enters in next step if qualified, returns the pcb board if unqualified Step 2 is returned from new cleaning;
Six, it will be recorded in pcb board plate boarding to management and control table, cleaning is completed.
As an optimization, the tin cream in the step 2 in pcb board plate face is purged using plastic cement stirring blade.
On the other hand, another embodiment of the present invention provides a kind of pcb board cleaning fixed fixture, and fixed fixture is rectangular Plate shape, the centrally disposed through-hole of jig, shape, the size of through-hole are corresponding with the shape of pcb board to be cleaned, size.
As an optimization, the bottom at left and right sides of the fixed fixture, which is provided with, takes board slot.
As an optimization, the depth for taking board slot is more than 10mm.
As an optimization, the top surface of the fixed fixture is provided with lower deep gouge, shape, size and the PCB to be cleaned of lower deep gouge Shape, the size of plate correspond to.
As an optimization, the sinking groove depth is less than or equal to the thickness of pcb board to be cleaned.
As an optimization, feeding slot is additionally provided at left and right sides of the fixed fixture top surface, under the depth of feeding slot is more than Deep gouge, feeding slot are connected to side and the through-hole of jig.
The effect provided in invention content is only the effect of embodiment, rather than invents all whole effects, above-mentioned Technical solution has the following advantages that or advantageous effect:
1. the pcb board clean method and fixed fixture the effective solution pcb board caused by pcb board cleaning is not clean print Bad problem is brushed, solves the problems, such as that welding quality is bad, has saved the maintenance cost brought because of bad.It is good by improving Product rate, improves production capacity, and economic benefit is increased for enterprise.
2. by the centrally disposed through-hole in jig, it can prevent the tin cream on pcb board from polluting fixed fixture, it is therefore prevented that it The pollution of his pcb board.
3. taking board slot by setting, finger is stretched into and takes board slot that can lift jig plate, facilitates taking for jig plate.
4. by the lower deep gouge of setting, pcb board is caught in lower deep gouge and realizes fixation, and more effectively can smoothly fix pcb board makes It will not shake, and ensure being smoothed out for cleaning.
5. by the way that feeding slot is arranged, pcb board can conveniently be picked and placeed by being put into finger.
Description of the drawings
Fig. 1 is a kind of work flow diagram of embodiment of pcb board clean method.
Fig. 2 is that pcb board cleans a kind of overall construction drawing of embodiment of fixed fixture.
Specific implementation mode
In order to clearly illustrate the technical characterstic of this programme, below by specific implementation mode, and its attached drawing is combined, to this Invention is described in detail.Following disclosure provides many different embodiments or example is used for realizing the different knots of the present invention Structure.In order to simplify disclosure of the invention, hereinafter the component of specific examples and setting are described.In addition, the present invention can be with Repeat reference numerals and/or letter in different examples.This repetition is that for purposes of simplicity and clarity, itself is not indicated Relationship between various embodiments and/or setting is discussed.It should be noted that illustrated component is not necessarily to scale in the accompanying drawings It draws.Present invention omits the descriptions to known assemblies and treatment technology and process to avoid the present invention is unnecessarily limiting.
Fig. 1 is a kind of embodiment of pcb board clean method, as shown, a kind of pcb board clean method, including following step Suddenly,
