The problem of the plating of the wire is rough, the coating blister and the deposition speed is slow..
1 the coating is rough and the passivation film is not bright. Bath temperature is too high; cathodic current density is too large, the plating liquid in high levels of zinc or sodium hydroxide and DPE content is too low; plating fluid solid particles or metal impurities such as will cause the fault.
2 coating foaming, the combination is not good. The temperature of the plating bath is not good, the additive quality is bad or the additive and the organic impurities can cause the joint force not well..
3 slow deposition rate, deep plating ability. The low temperature of the plating bath, the low current density of the cathode, the content of sodium hydroxide in the plating bath or DPE content in the plating bath or the impurities such as lead and other impurities can appear this kind of problems..
