IPC-SM-840. If overall thickness is not specified in purchasing documents, a supplier will do whatever it wants. Specify your requirements. Typical values are 20-50um. Regards

Hello Everyone, I have noticed that everytime that we have ran a PCB with fine pitch components (or even 0603s), there are little white strands on the leads or on top of the components. It occurs on both lead and lead free solder. We usually soak
