In our production process using tin plating brighteners, sometimes the solderability of the coating is poor. Do we have any good measures to solve this?
When we use sulfate tin plating brightener to produce, because of the particularity of stannous ions in the plating solution, the strong acidity of the plating solution and the lack of complexing agent in the plating solution, the maintenance and management of the plating solution are very important.So what parameters need to be paid attention to in the daily production process?
In the production process of using alkaline galvanizing brightener, if there is a large amount of sodium carbonate in the plating solution, it will affect the normal use of the plating solution and cause failures.So how does the sodium carbonate in the plating solution come from?
When aluminum alloy workpieces are produced with electroless nickel plating solution, sometimes the phenomenon that the coating cannot be deposited, what is the reason?
In the production process of using alkaline galvanizing additives, sometimes the surface of the workpiece will appear rough and not bright, what is going on?
When we use the trivalent chrome color zinc passivation solution to produce, sometimes the coating film will have poor adhesion and easy peeling. How to solve this?
