Why do Optical Chip Production Lines Generally Use COC Fishbone Fixtures/Clamps?

♦ Precise Damage Prevention: Independent elastic springs apply pressure evenly at multiple points, ensuring uniform force distribution and preventing chip deformation, edge chipping, and plating damage;

♦ Process Compatibility: One-stop adaptation for the entire process of wire bonding, room temperature testing, high-temperature aging, and retesting. Automated production lines reduce multiple material transfers and fixture changes;

♦ High-Efficiency Mass Production: Simultaneously adaptable to manual sample production and automated equipment, catering to both small-batch R&D and large-scale mass production needs;

♦ Strong Stability: Wide temperature control adaptation range, less prone to deformation and displacement under high-temperature aging conditions, reducing test data errors;

♦ Wide Versatility: Supports customized adaptation to different sizes of COC and CoS carriers; some customized solutions are compatible with specific TO-type device testing.
