Hi all: We are seeing "solder webbing" on the bottom side of some of our PCBs after wave solder. The solder is sticking (like a spider web) to the solder mask on the PCB. This is only happening on 2 of the many PCBs we wave on that machine. Both o

Now that's surprising that your board fabricator would say the mask was cured properly [without even inspecting the boards]. I wonder if they can backup those BOLD words when testing your boards with the webbing problem. The reason you can�t find t

One of the DFM suggestions I've seen is to remove the solder mask web, i.e. the mask between pads on 20-mil QFP devices. The rational is that if the mask is thicker than the pad the mask can prevent the stencil from making intimate contact with the
