If that's the case, let your customer go. I have run into this situation recently. Q. Why do you not run a dedicated line for lead free? A. You (the customer) give less than 12 weeks forcast and expect us to have a dedicated line for your product?

We have a name brand aqueous batch cleaner that uses a chemical and DI water to clean ROL0 flux from our PCBs. It does ok most of the time for SMT boards and we want to include through hole assemblies as well which should be a better cleaning process

Hey there fellow people with SMT issues... What's the proper procedure for soldering through-hole headers on the back-side of the PCB (pins poking out on same side as SMT parts)? ( Yes - I did the SMT side first and am now faced with LOTS of pin-poin
