No, raising the solder pot temperature to 800*F will not affect affect your solder alloy. We expect that you had a fairly high level of intermetallic compound generation, but most of that would be included in the fairly high dross generation that ha

According to J-STD-033 Table 4-1, the bake out time to restore the clock to zero is not only determined by the MSL level, but the package thickness as well. Section 4.2.2 states "SMD packages shipped in low temperature carriers may not be baked in t

We use copper grease on the bolts of our wave solder machines solder pot. The working temperature is up to 1000degC. I believe that the boiling point of mineral oil is a little over 300degC and you will exceed this with iron temperatures, especially

Does any one know of a supplier high temperature PCB ink that can safely used between pads on an SMT connector. The product ideally should be screened on and have resistant to short exposure to heat from a selective lazer. Must be non-conductive and

DevGru: Questions are: * What steps do you recommend taking to "watch out for the exothermic heat from the curing?" * What are typical temperatures for exothermic heat from the curing? * What is the duration of such temperatures? * Do epoxy suppliers

I have never had this come up before. We have a customer that would like all their BGAs baked before production. No a problem, but one of them is in tape and reel. I don't know the temperature limits of tape and reel. Has anyone done this and at what

Those components can be soldered at both SnPb and Pb Free Reflow process. In case you will submit them to Pb Free Reflow temperature you must treat those components as MSL-3 In case you will submit them to SnPb Reflow temperature, you must treat t

We have measured the temperature of CSP solder joint. The peak temperature is 232oC and the wetting time above 217oC is 30s. But we use leaded solder paste instead of lead free solder paste. I doubt why no crack of solder joint was observed after cr

These images are of two melted matrix trays, full of BGA components, which were left to bake in an oven over the weekend. The oven temperature controller was not checked after a recent power failure and reached a temperature of 715�F. The two trays m

It depends on the type of iron. Some of ours have a little plug you pull out that exposes a pot that you tweak to make the temperature of the tip the same as the reading. Others can't be adjusted and the heating element must be replaced if they don't
