If you need substrate clamping without compromise, look no further than our Over Top Snuggers (OTS) technology. Securing printed circuit boards firmly in place ready for processing, the flexible technology is designed to ensure high quality printing for enhanced end-of-line yield.


OTS is a sophisticated device that clamps the board flat before enabling finite snugging and clamp control for precise board location. The board is pulled down flat to enable a strong vacuum tooling contact; the clamps are then pulled away from the board top face surface to allow close edge printing. By optimising edge printed paste deposits, this process substantially enhances yield potential.


In addition to optimal paste deposition, the highly flexible OTS system automatically adjusts for variations in board thickness, eliminating set-up requirements between production batches and runs. Reinforcing the flexibility and security of substrate location even further, OTS’ compliant clamps will also automatically adjust for out-of-parallel boards.
