The combination of press-fit pins and servo-electric presses provide a powerful technique for automating and verifying the integrity of board-to-board connector installations. Press-fit connectors have begun to dominate high-end connector applications for telecommunications and computer printed circuit boards (PCB). Compliant press-fit pins come in several styles, including the C-section, action pin and eye of the needle. The press-fit compliant solution provides many advantages when compared with soldering. In surface-mount applications press-fit connectors eliminate the expense of wave solder pallets and masking. In many cases the combination of surface-mount and press-fit connectors can obviate the wave solder process entirely. Servo electric presses fall into such categories as manual, force assisted manual, semiautomatic and fully automatic. These presses sense and record the key press-fit connector variables, providing documentation of the press-fit process for each connector and board.
