Has anyone here had issues with Titan's (Board house) Leadfree / Rohs compliant boards blistering at lead free temps? MAX temp 250c thx

Jerry, In your initial post you give 260C as solder pot temp if you�re not using lead-free I would reduce the temp to 250C this will also reduce oxidation rate.

Shenzen Comofaje sell out of China, delivery to Ireland takes about a week, but prices are much lower, $15-40 for 250/500 strips. Our ops are happy enough with them http://comofaje.en.alibaba.com/

In regards to the Torque tester from Fuji that tests the peel back force, you can buy that directly from Fuji for $250.

We have both NXT and AIM. Be aware of the width limitation (250mm?)on the M3 module, if you go over it then you have to pair with an adjacent module to build the board.

Help, experiencing discolor of a white solder resist paint after reflow of 250 degree, it turned yellow. Have tried many paints, no luck. Anyone knows one that wouldn't change color and holds the white nicely? Thanks for your support in advance.

We have tried 2. The first is 244C and the 2nd is 252C. The processor BGA document recommends a solder temperature above 250C. Eric

We encoutered few PCB after IR reflow the PCB pad change color from silver to yellowish / brownish. Our IR reflow peak temp is ~250 degree. The brownish cannot be remove with IPA as well. What is the main reason causing this issue?

Thanks Dave I tried various sockts but all were failed.At SnPb profile,maximum- 230'c~240'c, the solder at sockets' pins not melted.Increasing to 250'C, the sockts were deformed.

Why doesn't your leaded paste melt until you get it to 250*C? Is that across the whole board or just at the locations with the sockets?
