Further, in step D, baking temperature is 105 DEG C.
Further, in step D, baking time 50min.
Further, in step F and H, drying is hot-air seasoning.
Further, in step F and H, pcb board all also passes through deionized water rinsing after clear water cleaning, before drying.
Further, in step G, hydrogen peroxide concentration 70g/L.
Beneficial effects of the present invention are：The present invention discloses a kind of pcb board method for plugging of anti-foaming, sets rational baking
It parameter and nog plate parameter, can effectively slow down the unavoidable reaction that anti-solder ink is occurred with OSP micro-corrosion liquids, and can make
The unnecessary anti-solder ink in filling perforation edge obtains sufficient polish-brush, so as to effectively reduce the contact area of ink and OSP micro-corrosion liquids, drop
The probability of low anti-solder ink foaming, in addition, setting rational OSP parameters, can significantly reduce OSP micro-corrosion liquids to anti-welding in filling perforation
The attack of ink, the probability of anti-solder ink foaming is fully reduced, and cleaning in time is remained on pcb board after OSP processing is completed
OSP micro-corrosion liquids, can further reduce ink foaming probability.
Embodiment
For the feature of the present invention, technological means and the specific purposes reached, function can be further appreciated that, with reference to
Embodiment is described in further detail to the present invention.
The embodiment of the present invention discloses a kind of pcb board method for plugging of anti-foaming, comprises the following steps：
A, pcb board is prepared：A pcb board is provided, pcb board is provided with the filling perforation of ink to be filled in；
B, silk-screen half tone is made：According to the design requirement of pcb board, by the film, silk-screen half tone is made in exposure imaging on grenadine；
C, consent：Silk-screen half tone alignment pcb board is placed, anti-solder ink is filled into filling perforation by silk-screen half tone；
D, toast：Pcb board is toasted, solidifies anti-solder ink, baking temperature be 100~120 DEG C, baking time be 50~
60min, it can effectively slow down the unavoidable reaction that anti-solder ink is occurred with OSP micro-corrosion liquids, so as to reduce anti-solder ink
There is the probability bubbled；
E, nog plate：Nog plate is carried out to all consent faces of pcb board, the face where filling perforation mouth is consent face, and filling perforation edge is unnecessary
Anti-solder ink polish, nog plate speed is 1.8~2.0m/min, and nog plate pressure is 2.8~3.0kg/cm2, filling perforation side can be made
The unnecessary anti-solder ink of edge obtains sufficient polish-brush；
