We find that 30–40% of the tools show salt bleed-out at the joints. Can you suggest anything we can do to solve this problem?
Read MoreBulk Electropolishing
Is there any way to bulk electropolish smaller parts? We have received requests to electropolish parts that are small and difficult to individually rack. We were thinking of using a barrel technique to do this. Will it work?

We normally operate the plating bath in a temperature range of 50–60°C. Recently the temperature was allowed to reach 70°C due to a broken thermostat. Since the temperature upset, our plating has been pitted, burnt and stressed. Did we ruin the plating bath because of this temperature upset? Can the plating bath be salvaged?

We occasionally have problems with dewetting of our pure gold plating during the soldering step. The parts we plate are thin, made of copper and have a sulfamate nickel strike on them. Do you have any suggestions on how we might solve this problem?
Read MoreAnother Citric Acid Passivation Question
We are having a problem with citric acid passivation of 303 stainless steel. The parts continue to fail a 24-hour salt spray test. Currently we passivate for 30 min. Should we double the amount of time in the citric acid? Do you have any suggestions for us?
