Detail the cause of multilayer circuit board electroplating on nickel gold tin plate?

multilayer circuit board electroplating nickel gold plate cause analysis, tin can be studied from the following aspects of adjustment


1, and false gold-plated layer, and nickel layer washing time is too long or oxidation passivation, pay attention to pure water and strengthen the use of hot water washing time control.


2, electroless nickel plating or nickel cylinder problem: pollution heavy metal pollution agents, recommended low current electrolysis or active carbon filter element, PH value, dilute sulfuric acid or abnormal nickel carbonate, nickel coating thickness adjustment can be not enough, porosity is too high, check nickel plating current density, current on the table to check the current rod current and instrument display current time consistency, nickel, when necessary to do metallographic view Observe the thickness and surface condition of nickel layer; This can occur with low/high slot additives between nickel plating layers, but the additives may be lower. In addition, the nickel chloride content has little effect on the solderability of the nickel layer, with a focus on optimal value adjustment, high strength, and large and high porosity in the lower layers.


3, electroplating pretreatment: oil removal, acid recently low temperature, there may be a part of resistance welding PCB board proofing surface residue or film/can not deal with the network, can adjust the temperature, concentration in oil/also pay attention to other cavitation depth and plate surface uniform skin color.


4. Bad post-processing; After washing should be timely dry, well-ventilated place, preferably not in the plating workshop!


5. Other multilayer circuit boards are also worth noting that the quality requirements of all chemical treatment and clean water are higher than those of general electroplating. ! ! ! ! General municipal water/tap water, circulating water/well water lake is recommended not to use, because of the hardness of the water/contains other complex organic substances!

Keyou circuit is a professional production of high precision double-sided multilayer circuit board, module gold circuit board, car circuit board, car charging circuit board, traffic recorder,COB power supply, computer motherboard, medical circuit board, module board, thermoelectric separation copper substrate, etc., quality assurance, delivery on time, to sales as one of the high-tech enterprises.
