Experts, If I have to allow my CM to use No Clean solder paste, what kind of note should I put on assembly drawing (with some kind of qualification requirement)? Our product is for telecom/networking industry so I rather specify some kind of qualification requirements (if any) than just write - use no clean solder paste. I know all pastes are not same and may not be suitable for certain industry. I used to put a note on my assembly drawing for hand soldering something like... HAND SOLDER FOLLOWING COMPONENTS USING TELCORDIA (BELCORE) COMPLIANT NO-CLEAN FLUX. Any help will be appreciated. Thanking you in advance.
