I have the situation where we may need to use a variety of reflow temperatures. It seems that the design engineers want us to try a variety of "unspecified" pastes on the products. For example, the first PCB would be assembled using a higher temperat

Hey!!! Watch it!!! I don�t want to get you believing too much of this stuff. But if you bought that, listen to this � some circuits are so critical with that skin effect stuff that they use silver as the top level solderability preservative. Turn

To all, This may appear to be laziness on my part, but I need to ask for some advice. We are in the process of qualifying no-clean solder paste to replace or current RMA paste. I have performed qualification runs and extensive reliability testing

Hi all Pls. help advise. Our board use RMA solder paste (Pb-free Sn96.5/Ag3.0/Cu0.5). Can we use No-clean paste flux (Delta 670S1) in rework process? If it can not be used, why?. Thanks very much for your advice. Surachai

J-STD-001C, 7.2.1 Flux Application says words to the effect of: When an external flux is used in conjunction with flux cored solders, the fluxes shall be compatible. Regardless of whether these are or not flux cored solders, this begs the question:
