FPC flexible circuit board can not ignore the influence of fingerprint

 　　FPC flexible circuit board in the process of processing if do not pay attention to touch the circuit board welding pad with your croquette, especially do face treatment of FPC, the flexible circuit board will beget oxidation.


　　FPC flexible circuit board face oxidation in the welding of factors, easy to beget shelling and scrap, because croquette marks are sweat stains, some inorganic tar and fat,etc., easy to beget circuit board paralysis.


　　What are the troubles of a bitsy croquette print?


　　1. Touching the flexible circuit board with your croquette will beget the bull on the board to suffer chemical response in a truly short time, leading to the oxidation of the bull face.


　　After a little longer time in electroplating after obvious fingerprints, uneven coating, causing serious scars in the appearance of the product.


　　2. Cutlet contact with FPC board ahead solder resistance will lead to poor adhesion of the covering film beneath solder resistance.


　　3. During the process from resistance welding to packaging of submerged gold plate, bare hands touching the plate face will lead to sick plate face and poor weldability.


　　Still, this croquette print phenomenon will beget great damage to the good rate of products, If not prevented. In the product process of flexible circuit board, Yongmingsheng circuit board factory strictly requires workers to wear croquette gloves to hold the board, thus greatly reducing the rework rate and perfecting the work effectiveness.
