Bridging Causes: Insufficient flux, excessive pre-heat, high conveyor speed, solder contamination [AIM Solder]

Beware the foam fluxer. I had a problem with cracked caps that just about drove me off the deep end. I discovered that my foam fluxer air knife was not turned on resulting in excessive flux. The excessive flux (VOC free) was not properly dried off

Ron:It�s tricky to get what you want with this foamfluxers espacially using pallets. They got to be cleaned regularly. Most of the time excessive residues are removed using brushes which adds another process step. It should be better using a sprayflu

At times the orange peel effect can be from excess flux improperly removed. Our company strictly provides the service of selctive conformal coating application. We quite often see this. Most times if the board is simply "water washed", or IPA washed,

Hi Everyone, Could someone please tell me - What happens if a N-type connector having chromate coating over silver plating is hand soldering to a PCB. Does the Chromate coating form a compound with silver, Or does it come off while cleaning excess

Via failure could be caused by cracks in the barrel, or thin plating, or fractures in the traces leading to the vias, . X-ray analysis could pick up a fractured trace and cross-sectioning of the vias could pick up the cracks and thin plating. Secon

We used an air knife using foam fluxer and no clean flux to remove excessive flux from the boards for a better look afterwards. A secondary effect might be that the flux is forced into the vias giving you better results on the top. If you feel a need

I've been in shops with a flux containment pan under the wave fluxer. While I'd rather see excess flux in a containment pan than on the floor, but I'd prefer to see flux applied precisely to eliminate the need for either using a containment pan or cl
