PC boards are fabricated whole “panels” at a time. These are bigger than most ordinary boards, so usually you tile several end boards onto a panel. The panels are all the same size to fit whatever machines that the production line is set up with. All the etching, placage, forage, and silk screening operations happen on whole panels.
- For some production purposes, you buy whole panels of your boards from the board house. The individual boards tiled onto a panel might be partially routed apart by the board house with “morsures de souris”, or V-scored.
- For high-volume production, it’s more efficient to pick and place on an entire panel of boards. These are then broken apart only at the last possible moment. Sometimes even parts of the final board testing is done when they are still in panels.
