We have experienced a problem with tin leaching or discoloration of lead terminals on random parts on solder side of a paste/paste operation. The profile has been used on previous production runs and there doesn't appear to be any heat damage to othe

I'm thinking that your soldering irons are not up to the task. take a tip temperature measurement of the iron prior to and during soldering process. With high temp solder alloys you need an iron that provides continuous temperature at the tip. Doing

I'm also looking for tips for SMT hand soldering with Sn05Pb93.5Ag1.5. Our technician is quite good with standard SMT hand soldering, but hasn't worked with HMP solder. Some specific questions: - If the iron tip is hot enough (consistently), can we

Hi, We are currently having issues with hand soldering High melting point solder wire. Can anyone give a few tips. We are Preheating boards to 120 deg C and using soldering irons @ 410 deg C. The quality is ok but the ts taking 20-30 seconds to c

Thanks for the advice. We have only done one PCB with HMP solder and did not use preheating, but I've been wondering if it would have been helpful since we had some trouble getting the solder to flow. If you have any more specific advice about the te

I'm looking for a preheater for hand soldering, but haven't used one before so I could use some advice. Does anyone have any preferred styles or brands? Is there anything in particular that I should either look for or should avoid? I've seen prices r
