Q. Hi, I am a technical support in electroplating industry. Currently, i am working on ENEPIG plating on PCB. The EPd solution is taken from my supplier. However, the EPd is very unstable which it is very easy to plate out. I stored the EPd in carboys and every week I saw plate out on the bottom of carboys. I then transferred the EPd to new carboys and added 1ml/L of EPd stabilizer every week suggested by my supplier, but the issue still occurs. I have no idea why EPd keep plating out and I can't find any sources online. Can anyone please help me to find the potential issues that cause the plate out. Thank you so much!
