2. Second, according to the size and pin layout of the tubular IC, design and manufacture the PCB board. there will be pads on the PCB board corresponding to the pins of the tubular IC.
3. Then, the tubular IC is patched onto the pads, followed by the soldering process. By means of hot air or hot plate, etc., the tubular IC is soldered to the pads on the PCB board so that they are firmly connected together.
4. Finally, inspection and testing of the tubular IC is performed. This includes testing the functional, performance and electrical characteristics of the tubular IC using automated test equipment to ensure its quality and reliability.
