Mr. Xiong found that the dispersion of the workpiece coating was relatively poor when using tin plating additives. The tin coating in the low current area was thin, which affected the weldability of the workpiece.So Mr. Xiong wants to find a good dispersion of methanesulfonic acid tin plating additive.
Mr. Xu of Tianjin has opened a new production line of methanesulfonic acid type tin plating, which is ready for precise electronic product tin plating processing and production.According to a friend, Mr. Xu used a tin plating brightener, and the workpiece coating was prone to appear blue and yellow, which seriously affected the performance and service life of the workpiece.So Mr. Xu wants to find a better performance methanesulfonic acid tin plating brightener.
Due to production needs, Mr. Chen thinks that the plating speed of his electroless copper plating solution is slow, only 2-3 μm/hour, seriously affecting the production progress.So Mr. Chen wants to find a electroless copper plating additive with fast deposition speed.
Mr. Yang's screws had no problem with the coating after zinc acid plating, but when plating a batch of spring parts, the coating of the workpiece always peeled.Because the coating quality of the workpiece is poor and cannot meet the customer's requirements, Mr. Yang does not want to lose this big customer, so he wants to look for an acid zinc plating brightener that will not peel.
Recently, when Mr. Mai used electroless nickel plating solution, the coating surface of the workpiece after chemical nickel plating is normal, but after hot water washing, the workpiece will be baked in the oven for 10 minutes, and there will be a layer of white water mist on the coating surface.Since the appearance quality of the workpiece is seriously affected, Mr. Mai asked Bigolly engineers to help solve this problem.
Mr. Zhang used the acid tin plating brightener to prepare the bath after new preparation. Although the coating color of the workpiece was uniform after tin plating according to the process parameters, the brightness was relatively poor, and the addition of brightener did not improve.What causes this?
