Abstract
The present invention provides a kind of anti-welding one side windowing via manufacture method, can solve the problem that via consent printing opacity is bad and customer complaint is leaked bleed and solidify afterwards bullet oil after stannum short circuit problem, and via development and causes problem of faulty soldering by the inventive method.
Description
Technical field
The invention belongs to wiring board processing technique field, more particularly to a kind of anti-welding one side windowing via manufacture method.
Background technology
Now with the densification degree more and more higher of pcb board structure, PCB design person is more and more designed on paster
Via, and it is relatively common, using its operation technique long flow path of filling holes with resin, high cost；Conventionally employed even plug band India side formula is made
There is printing opacity bad phenomenon in industry, anti-welding one side windowing via, there is leakage stannum short circuit hidden danger, and the first aluminium flake net consent of printing prints face oil again
, then there is the quality problem such as PAD and solidify afterwards bleed on development via oil spilling in mode.
The content of the invention
In view of this, the present invention provides a kind of anti-welding one side windowing via manufacture method, can be solved by the inventive method
Certainly via consent printing opacity is bad and customer complaint leaks stannum short circuit problem, and bleed and solidify afterwards bullet oil cause rosin joint after via develops
Problem.
The technical scheme is that：A kind of anti-welding one side windowing via manufacture method, including anti-pre-welding treatment, anti-welding print
Brush, para-position exposure, standing, development, post cure step, when opening one side window via operation is carried out after anti-welding printing, if one side windowing
When hole aperture is 0.1-0.25mm, cancel correspondence aluminium flake net consent, using even plug band India side formula；If one side opening aperture is
During 0.25-0.35mm, aluminium flake net consent bores nozzle and gets out by 0.3-0.4mm apertures.
Further, the online one side windowing of the consent aluminium flake corresponded to a diameter of 0.2-0.3mm of hole drill nozzle, can reduce hole
Interior plug oil mass.
Further, the aluminium flake aperture compensation ± 0.01-0.03mm of the anti-welding one side windowing via.
Further, during development, facet time puts plate operation, and solder mask window faces down development, has anti-welding one side when two-sided
Windowing design, then select the placed face down more than hole count quantity, can reduce pool effect.
Further, during development, washing pressure is 0.7-1.2kg/cm2.Reduce washing pressure to avoid because of anti-welding one side
In windowing via hole, without exposure curing, into liquid form, ink is easily rushed out to return is stained with plate face to ink to ink.
The anti-welding one side windowing via manufacture method that the present invention passes through, by screening different via diameters, using even plug band
Print or aluminium flake net consent mode are printed, and can reduce the corresponding consent of anti-welding one side windowing via and bore nozzle diameter, reduce in hole
Tank oil mass, it is to avoid in development, ink overflow in hole goes out, PAD in residual；And when developing reduce washing pressure, can avoid because
In anti-welding one side windowing via hole, without exposure curing, into liquid form, ink is easily rushed out to return is stained with plate face to ink to ink.It is logical
Cross the inventive method and can solve the problem that via consent printing opacity is bad and customer complaint leakage stannum short circuit problem, and after via development bleed and
Solidify afterwards bullet oil causes problem of faulty soldering.
