What would be a typical thermal test regime to verify the quality of solder joints for high specification applications - what would be the specific benefits of utilizing a "HALT" process over other traditional test techniques ?

Yes. Baking boards is best. Hitting the hamer on the head!

They must live in a perfect world where they give you perfect boards and perfects parts.

Don't tell them you repaired them.

Being very new to SMT I won't assume I know what the problem is but.... I had lots of air pockets in solder joints, 95% of the boards. Everyone I spoke to thought it was a problem with my process but when one board was sent to our supplier they admi

How about your bare pcb handling? do you stuff smd component prior hand soldering? you can try to bake the pcb and then see if this problem still exist.

Do your boards only have three parts on them? Otherwise, i dont see how this is possible. Do you scrap the board if there is an issue or do you fix it and make it look like reflow soldering?

We do selective soldering here so if you attach the pictures I might be able to offer some suggestions.

Hi, I have received a report form a board supplier, analysing the reuslts form non wetting problems we have been expereincing with their boards. I assumed it was due to the gold layer being too thin, thus allowing the nicklel layer to be exposed and

This processes has the potential to cause barrel cracking and pad lifting, because the heating is very hot [troop crank-up the volume on their iron when they see thick boards] for a relatively small area on one side of the board. What do we suggest
