Check the bare board - could also be an unmasked via on the heel of the pad that is sucking solder into it.

groundplane not heating properly.. Is it a J leaded IC? sometimes these get bent slightly in the packaging and sit just far enough off the board to cause solder problems.

I'm having problems with trying to get a good solder joint using a Ceramic PCB. We are using AMTECH hi-temp solder (ws-486 96.5/3.5ag). My profile looks great and I used the recommended profile from Amtech with a few adjustments. My max temp is about

The assumption that a HASL Sn63 PCB can be soldered with SAC solder paste is likely a bad one. The board itself is likely FR4 which can be damaged by lead free temperatures. The HASL finish isn't an issue from the perspective of it's makeup and actu

We are looking at a specialized method of direct soldering ceramic circuit modules (maybe 40mm square) to a mother board with solder joints on only 2 of the 4 sides. These modules would be oriented horizontally, or mezzanine like, to the mother board

Dave: Actually, I'm located in the South Bay (Santa Clara)! Good guess. Now, for more in-depth information: So far, the distribution has been limited to one board out of 10 assembled, so far from one lot. The components assembled are exclusively
