When we use pyrophosphate copper plating brightener, why the plating tends to burn?

As the workpiece high area of the main salt metal ions discharge too fast, in the cathode interface liquid layer due to insufficient mass transfer, resulting in a large concentration difference with the depth of the solution, the cathodic polarization value is too large, in which case, in the low cathodic current density of discharge difficulties in hydrogen ions to take advantage of the opportunity to a large number of discharge reductions, on the one hand, hydrogen, on the other hand, the interface is also due to the insufficient mass transfer of hydrogen ions lead to pH rise, the formation of metal hydroxide, etc., intermingled in the At this time, the plating layer is either rough, or loose and porous and spongy, so scorching occurs.

We can use Bigely pyrophosphate copper plating brightener Cu-203, it is a product developed by a team of engineers after several years of precipitation, with a wide range of permissible current densities, which can ensure that the plating solution deposits a crystalline and detailed copper plating layer under a higher range of current densities, without burning and other faults.
