We have a customer enquiry that requires PCB assemblies to be cleaned to J-STD-001 / -004 class 3. We use both water based and no clean process chemistries. No clean flux residues are not permitted and would therefore have to be cleaned. My question

Do we really need to follow the IPC J-STD-001 Solder purity? If so, how to effectively balance the chemistry of Sn63/Pb37 other than adding a pure tin on the solder bath? Is this really needed to monitor in monthly basis?How many kgs of pure tin pe
