This application provides a bead-stringing fixture for the immersion
nickel-gold process of printed circuit boards, belonging to the field of PCB
manufacturing technology. The fixture includes an upper comb-tooth insert plate, a first non-elastic high-strength
fishing line, a lower comb-tooth insert plate, a second non-elastic high-strength
fishing line, and a third non-elastic high-strength
fishing line. The frameless design of this fixture increases production capacity and reduces chemical carryover, thus saving costs and improving production efficiency. The use of high-strength materials ensures stability and
corrosion resistance, guaranteeing the fixture's stability and durability during long-term operation, reducing maintenance frequency, lowering production costs, and providing a stable and durable structure. The upper and lower comb-tooth insert plates offer maximum capacity improvement, increased efficiency, and
cost savings for immersion
nickel-gold processes and multi-piece operations on gantry lines, making it highly adaptable.
