Ensure safety and precision in PCB board prototyping by adhering to guidelines such as insulation for soldering irons, understanding IC functionality, using isolation transformers, high-resistance test instruments, monitoring heat dissipation, maintaining solder quality, rationalizing lead wire testing, cautious IC diagnosis, and preventing pin short circuits.
Defective PCBAs post-inspection necessitate repair, employing either manual soldering with constant temperature irons or hot air welding. Soldering iron usage demands completion within 5 seconds, ideally 3, with preparation including coating with solder and precautions against oxide layer formation. Hot air welding on a repair workbench suits QFP, BGA, PLCC, and intricate components, necessitating specific nozzles and adherence to operational manuals, featuring temperature curves akin to reflow furnaces in advanced models like the company’s SMD-1000.
The methods for completely disassembling an integrated circuit include using a tin suction device, an internal thermal desolder removal method, and a medical hollow core needle disassembly method.
