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

Had the very same thing happen the first time we used the small QFNs. The aperture for the thermal pad in the center needs to be cut in a grid form, either squares (with around a 10 mil spacing between openings) or circles, like a BGA pattern. Too mu

Head-in-pillow (HiP), also known as ball-and-socket, is a solder joint defect where the solder paste deposit wets the pad, but does not fully wet the ball. This results in a solder joint with enough of a connection to have electrical integrity, but lacking sufficient mechanical strength. Due to the lack of solder joint strength, these components may fail with very little mechanical or thermal stress. This potentially costly defect is not usually detected in functional testing, and only shows up as a failure in the field after the assembly has been exposed to some physical or thermal stress.
Flux spray coating on a PCB with uniformal thickness down to 5 microns, with clear edge definition and minimal overspray. Can coat large or shoot dots with the same jet.
