PCBGRIP electronics assembly system holds printed circuit boards in place to aid in the speed of assembly. Flexible, modular design is said to simplify a variety of electronics assembly tasks, including holding through-hole components (even upside down) in place during soldering; holding SMT stencils during paste application, and holding components in place. Permits PCB to be rotated, tilted, swung around, or raised/lowered.
