Description

Technical Field

[0001] This utility model belongs to the field of printed circuit board storage, specifically relating to a variable width printed circuit board storage rack. Background Technology

[0002] In the electronic assembly process, the surface mount section receives materials and PCBs from the production preparation unit at the front end and outputs PCBAs to the insertion / manual soldering unit at the rear end. Due to production planning and interruptions, the surface mount section inevitably needs to store work-in-process (including materials, PCBs, and PCBAs). Materials are stored in low-humidity cabinets to ensure constant temperature and humidity. PCBs and PCBAs are stored on turnover racks by the surface mount section. Because these racks are open, their temperature and humidity fluctuate with changes in the production line's temperature and humidity. Since the production line's temperature and humidity control equipment is turned off during non-working hours, there is some loss of temperature and humidity control for PCBs and PCBAs in the surface mount section. Furthermore, the PCBs received by the surface mount section are stacked, making them prone to scratches and damage during storage and retrieval. The current storage method poses a significant risk and urgently needs improvement. Utility Model Content
