Hi "theSaint", We are using SN100C in our wave solder machine. As far as the solder itself, the wave process follows pretty much the same concept as leaded solder. You bring the assembly temp to 90 C or more before the actual wave. Sometimes for mul

This is a bad situation and if you use (better to rework) adhesive that means it will work worse in your normal process(wont hold). Heat all the leads to reflow temp, twist (rotate)the part untill it breaks free. Most adhesives are not designed for t

Sorry theres a mistake on previous question. It should be lead free component termination but non lead free solder alloy Sn63/Pb37. The reflow profile i am using : Soaking temp. 120 to 160 deg C; time 90 to 120 sec. Peak temp. 215 to 225 deg C; time

Hello all, I am looking for a high temp lead free solder wire to use when attaching thermocouples for oven profiling. I figure something that reflows at 270-300c would do the trick. Can anyone give me a Brand, model# for such a solder? THANKS.

When the component suppliers specify the cap as no more than 50sec (or even less time)above 200C, is there any way the lead-free profile window will fit if we wil have to achieve a peak temp of 230c for at least 30sec for the lead-free process? maybe

Francisco, You need to be concerned about "lead-free" BGAs. The SAC balls will not reflow at at standard tin-lead process temps. I have seen many examples where this has been a very big problem. In once case the BGAs just poped-off when the board was

Nothing wrong with using RoHS BGAs except that the spheres won't melt/collapse at normal leaded reflow temps. Reliability will questionable. Some people use a hybrid profile with a slightly higher temp (~230C)and a slightly longer TAL (60 -90 sec).

From what I have read so far the temps are, if not close to being the same for both alloy formulas. Preheat is a function of flux activation and thermal shock. Solder temp varies from place to place. Russ

Hello, Some questions.... Are you running lead free? What alloy? What�s your pot temp at? Temp of the board after preheat? Are you getting any solder in the barrels (

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