LONG TERM Your plans to buy a vaccuum bag resealer and a batch drying oven sound good as you say, but you�re correct. They will not help with this current situation. SHORT TERM If your connections are clean, free of pits and holes with a smooth,

We have some BGA's that don't solder very well. They weren't properly stored in regards to moisture protection. The balls look dull and rough. After reflow there seemed to be a diffinate line between the balls and the solder on the PCB's. I think

Stephano- There is a Chemical process to revert the contamination back to its original form. The EMPF Developed it back a few years ago in conjunction with Rockwell and some others. Please contact ACI at 610-362-1200 and ask for Dr. Greg Parks. This

Baking before assembly does nothing good. It: * Increases costs. * Adds steps to the process and makes scheduling more cumbersome. * Increases the amount corrosion on solderable surfaces. We used to bake to remove the moisture from boards that caus

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
