(1) Plug-in: This part varies for each customer’s PCB. The equipment for plug-in is different for each customer. Some physical manufacturers use customized plug-in assembly lines. For customers in small batch production, consider purchasing two aluminum profiles and creating a PCB slot after lathe processing. This can make the plug-in process more efficient and save tin during dip soldering.
(2) Welding: The focus of this process is the equipment and solder used, which includes a PCB manual dip soldering machine, tin bar, and flux.
Principle: Dip soldering involves melting a large amount of tin in a tin furnace, immersing the soldering surface, and creating tin solder joints. This technique is essential for both plug-in technology and SMT red glue surfaces.
Introduction of dip soldering: Dip soldering involves dipping the PCB board with components inserted into a melting tin furnace to complete multiple solder joints simultaneously.
Operation process: Manual dip soldering requires a person to hold a fixture to clamp the inserted PCB and manually complete the dip soldering process.
The characteristics of manual dip soldering include simple equipment, easy operation, low investment, higher efficiency compared to manual soldering with a soldering iron, and producing beautiful solder joints.
(3) Foot cutting: The common cutting method in the market is to use a hand-push type circuit board cutting machine. The advantages of this method are high efficiency, resulting in neat and beautiful cut feet. The cost may range from 3000-6000. Of course, diagonal pliers are also a good choice for small batch development and production.
(4) Repair soldering: After the PCB is cut to the feet, the entire soldering process is completed. Next, it is necessary to trim the PCB and visually inspect the circuit board for any missing soldering, false soldering, or continuous soldering. These can be trimmed with a soldering iron, and if necessary, go through the tin furnace again.
(5) Cleaning and measurement: The repair welding part is just a simple trimming of the circuit board from the appearance. If you have high requirements for your own products, it still needs to be cleaned. The cleaning fluid used is professional plate washing water, which can be applied using manual brush or ultrasonic cleaning equipment. (The cost of this part is relatively high, and can be adjusted according to the actual situation)
Inspection and measurement: High-quality products need to be inspected using professional instruments. Commonly used testing instruments include oscilloscopes, withstand voltage testers, LCR digital bridges, and electronic load meters. Choose different instruments based on the functions to be tested. For advice on selecting the appropriate instruments, professional instrument sellers can be consulted. The individuals mentioned above have several years of experience in selling welding equipment.
