Mr. Li is the boss of a rolling tin plating factory for electronic components.When Mr. Li's diode workpiece was tinned some time ago, due to the use of the sulfuric acid system tin plating process, the workpiece was immersed in the plating solution for a long time during the barrel plating process, which led to the glass part of the diode being corroded and could not be used normally.So Mr. Li wanted to find a tin plating additive that would not corrode the glass.
the coating of the workpiece appeared zinc explosion.The operating parameters of the plating solution are all within the normal range, and the workpiece will still appear zinc explosion after adjusting the brightener and the plating solution.Due to the serious impact on normal production, Mr. Zhang was not easy to explain to the boss, so he wanted to quickly replace an alkaline galvanizing brightener with good performance.
Recently, a batch of steel ball valve workpieces produced by Mr. Feng have been coated with 10~15 μ m thick electroless nickel coating, which is very brittle, and always cracks and falls off after bending 180 °.Since Mr. Feng did not want to lose this big customer, he was eager to find a high phosphorus electroless nickel plating solution with small coating brittleness that could meet customer requirements.
When Mr. Dong's hinge workpiece is produced with barrel nickel brightener, although there is a slight blackening phenomenon in the low current area of the coating, the customer can barely accept it.Recently, a customer has a batch of battery shell workpieces that yellow and rust in the low current area after barrel nickel plating, which makes the customer very dissatisfied.So Mr. Dong wanted to find a barrel nickel plating brightener with good deep plating ability.
Mr. Shi was introduced by a friend to use the medium phosphorus electroless nickel plating additive, but after using this additive, the plating solution is prone to floccules, resulting in a large amount of potion and a short service life of the plating solution.So Mr. Shi wanted to find a medium phosphorus electroless nickel plating additive with better performance.
Mr. Pan from Xiamen, Fujian is the owner of an electroless nickel electroplating factory.Recently, in the process of using medium phosphorus electroless nickel plating solution, Mr. Pan found that the deep plating ability of the deep hole workpiece coating is relatively poor, which affects the performance requirements of the workpiece.So Mr. Pan asked Bigolly engineers whether this electroless nickel plating solution was not easy to use.
