We are currently handsoldering PCB jumpers. Does anybody have any experience on how the PCB-pad footprint design should be for screenprinting PCB jumpers to ensure that the connection is soldered?

The reason why we are using soldered PCB jumpers is that it is cheaper than dip-switches, 0 ohms resistors, etc. Field updating is also easier. We are producing different variants of some of our products. It would nice if we could presolder the PCB

rather than applying jumpers, try thinking it another way. Have all possible jumper connections pre-made by the fab design. Use an exacto or dremel to "open" the undesired paths by removing a bit of copper trace. total flexibility, only one fab make

Depends on what you're talking about. For instance: Jumpers between pads: Why not use SMT jumper components? Long ECO jumper runs: When we have a serious problem in the design of our boards, we contract thick film additive jumper work. Search th

Oooo, I get it. We do that trick on the wave solder side of boards. On the bare board, during design / layout, the basic shape of the jumper is a 125 thou disc of copper [that of course is eventually covered with whatever solderability preservative

I have a component that is glue cured on the bottom of a pcb. The component is a 1206 size jumper. It is made up of iron/nickel alloy. The problem I am having is that the part will fall off the board during wave solder. Is the component not able

Adam, As for stripping the boards.. get them right to start with. Believe me you don't want to clean them. If you have to remove the coating most conformal coating brands offer a removal agent that has been tested on most all component ranges. IF yo
