Description
Technical field
The present invention relates to a kind of FPC silver paste grouting steel disc grounded system practice.
Background technology
Flexible PCB is that the one made for base material with polyimides or mylar has height reliability, absolutely
Good flexible printed circuit；It is called for short soft board or FPC, has that distribution density is high, lightweight, thickness is thin
Advantage；FPC steel disc ground connection traditional handicraft is to stick on one layer of pure glue of conduction between steel disc and FPC, by pressure
Conjunction, baking-curing, it is achieved the electric conductivity between steel disc and FPC ground wire；Gluing poor performance is connect owing to conduction is pure,
Operating difficulties, and the unnecessary waste material in steel disc edge needs the most manual one by one to scrape clean process, so producing effect
Rate is the lowest；The pure glue that additionally conducts electricity is expensive, and production cost is high, and various limitation cause traditional handicraft
Optimization imperative；Thus the innovation FPC silver paste grouting steel disc grounded system practice, improves traditional handicraft efficiency
The defect that low, cost is high.
Summary of the invention
For the shortcoming of above-mentioned prior art, it is an object of the present invention to provide a kind of FPC silver paste grouting steel disc ground connection
Facture.
A kind of FPC silver paste grouting steel disc grounded system practice, comprises the steps:
(1) making circuit board with polyimides or mylar base material, design circuit trace-diagram, access area is bored
1.0mm hole；
(2) the region high adhesive-layer of print of holing avoided by circuit board glue；
(3) by glue bond steel disc patch FPC；
(4) high viscose glue and steel disc pressing；
(5) circuit board after pressing is through baking-curing；
(6) silver slurry is filled in hole；
(7) baking-curing；
(8) steel disc earthing test；
Described high viscose glue is one layer of Wear Characteristics of Epoxy Adhesive oxidant layer, and thickness is 12～20 μm；
Baking-curing is baking box direct baking, and condition is 160 DEG C/30 minutes；
Described pressing pressure is 80～120kg/cm2；
The general thickness of the FPC made by said method is between 0.05～0.5 millimeter.
The method compared with prior art, has the advantage that
A, production efficiency improve: high viscose glue is workable, and employee produces fast；Separately further each and every one need not clear up steel
Sheet edge waste, has saved a large amount of artificial；
B, cost are greatly reduced: conventional conductive pure glue about 0.2 yuan/PCS of steel disc ground connection cost of manufacture, silver paste grouting steel disc
About 0.08 yuan/PCS of ground connection cost of manufacture, manufacturing cost reduces by 60%.
The various limitation of FPC steel disc ground connection traditional handicraft, cause this link to become whole FPC industry production
Bottleneck operation；The silver paste grouting steel disc grounded system practice truly solves this difficult problem, and this method will have
More vast potential for future development.

1.0mm hole；
(2) the region high adhesive-layer of print of holing avoided by circuit board glue；
(3) by glue bond steel disc patch FPC；
(4) high viscose glue and steel disc pressing；
(5) circuit board after pressing is through baking-curing；
(6) silver slurry is filled in hole；
(7) baking-curing；
(8) steel disc earthing test.
Described high viscose glue is one layer of Wear Characteristics of Epoxy Adhesive oxidant layer, and thickness is 12～20 μm.
Baking-curing is baking box direct baking, and condition is 160 DEG C/30 minutes.
Described pressing pressure is 80～120kg/cm2。
The general thickness of the FPC made by said method is between 0.05～0.5 millimeter.
The above, only presently preferred embodiments of the present invention, not the present invention is made any pro forma limit
System；The those of ordinary skill of all industry all can shown in by specification accompanying drawing and the above and implement this swimmingly
Invention；But, all those skilled in the art are in the range of without departing from technical solution of the present invention, available
Disclosed above technology contents and a little change made, the equivalent variations modifying and develop, be the present invention
Equivalent embodiments；Meanwhile, all any equivalents made above example according to the substantial technological of the present invention become
Change change, modify and differentiation etc., within all still falling within the protection domain of technical scheme.
