Good evening, I�ve just solved very similar soldering issue. In my case the problem was with 0603 chips. Solder joint had same appearance. I suspected that solder do not melted and increased TAL and peak temperature. No result. Next thing I tried to

How do you melt it together ?

Darren: Do you know what these residues are ? How clean is your solderbath ? How often during a day do you clean it ? My first impression is that you deal with oxides. M2C Wolfgang

I know nothing about Xbox specific rework, but have a lot of experience with PCB repairs. "...maybe think its a bad idea now not knowing what im doing" Don't get discouraged, it's a learning process. If it was that easy everyone would be doing it.

Joe: I know this is not the correct forum to post chip "reworking" questions. Reply: Rework questions are as appropriate as the next topic here on SMTnet J: BGA will not reflow at any normal temperature level. I believe these chips may have been gen

Hi. In the past years I had made dozens of PCBs but now I am trying to get a professional finishing on them. The main problem is oxidation of the copper traces. Basically I use the silkscreen method to make the pattern in both layers and then etch. L

Jason: How did you determine that the deposits are tin oxide? What does this stuff look like? Klein Wassink "Soldering in Electronics" (p. 221, quoting original work by others). States (in effect) tin (or solder) quickly forms a protective oxide

Steve, How do you measure the resistance is it by probing the surface? Concerning the alloy there is a straightforward linear correlation between the tin content and the electrical conductivity of the alloy. The higher the tin content in the alloy,
