Embodiment 1
[0026] The invention proposes a design method for canceling the PCBA wave soldering process. The main idea of this method is: use a single-pin connector with a material temperature resistance higher than 280 degrees that can go through a reflow soldering process, and use a Pin in Paste through-hole process (Pin in Paste) in the surface mount technology process. ) first soldered to the printed circuit board, and then use the plug-in method to insert the parts that are not resistant to high temperature into these single-pin connectors.
[0027] Specific design plan:
[0028] Single pin connector:
[0029] Choose a single-pin connector, one end is a Pin pin, which is used for soldering with the through hole of the printed circuit board, using the Pin InPaste process; the other end is a pin hole, which is used for mechanical connection with the Pin pin of the DIP part.
[0030] Surface mount technology process PIP process:
[0031] According to the pin dipping solder paste th...
