1. What is the method for declaration RoHS for material like IPA, FLux & Solder paste. 2. What is the allowable limit for RoHS compliance for the above material?

I agree customer is being overly stringent, and that their is a possibility that BGA's have voids prior to installation. If you determine that the BGA's do not have voids prior to installation I suggest you slow down your ramp speed to allow the flu

Hi Everyone, Could someone please tell me - What happens if a N-type connector having chromate coating over silver plating is hand soldering to a PCB. Does the Chromate coating form a compound with silver, Or does it come off while cleaning excess

An industry issue??? Sounds more like another ROHS issue to me. Experience tells us the LF flux leave much more residue inside the oven

Davef, thnx for your reply. Sorry, forgot to clarify "our normal soldering process". We use standard Sn/Pb & SAC305 for our non RoHS & RoHS requirements. We only have a "No Clean" process, no aqueous flux is used. Hence our flux will be mild. As susp

If you add any "flux cored" wire solder to the pot make sure you have ventilation as the flux will burn off and smoke like crazy. This solder pot is like any used in a wave or selective solder, no flux. The flux is added to wire prior to di

We have already started to ship ROHS products to our customer since mid of last year. So far, I do not encounter any problems that you describe. Have to check with your flux manufacturer, is it for leadfree process?

Just 2 cents, lead free flux residue is no clean?, how about leaded flux? how much flux residue it leaves on both types? is there a clean up procedure after wave solder? or is there a wave solder process?

We are using Superior 515 flux to clean and tin selective solder nozzles. Yesterday the flux turned a bright yellow (like a highlighter) when heated after the flux being applied. This does not happen with our Lead Free solder, only the Lead alloy.
