Often, the need to solder wires into PC boards creates costs far in excess of the SMD assembly as this process is extremely labour intensive and a source of failure. These IDC contacts which can be assembled and soldered onto the board in the same SMT process as the other components solves this problem in a cost-effective way.
The solution was engineered for a company which required wires to be connected to a potted mini PCB and is an example of EDAC's ability at finding cost-saving connection solutions.
