The board-to-board connector is a miniature coupling plug and socket that can directly connect power and signals between printed circuit boards through the pins of the connector. Because the board-to-board connector is getting smaller and smaller, the pin density of the design is getting higher and higher, so the pins of the board-to-board connector are generally more difficult to solder. Because if the distance between the pins is too close during welding, the two pins may be welded together without care, which will affect the welding effect.

For the soldering process of board-to-board connectors, some techniques can make the connector products more quality assurance.
1. Applying flux to the solder joint pins before soldering can make the soldering smoother.
2. After applying the flux, use a soldering iron to clean the tin on each solder joint to prevent too much tin on the solder joint from causing false soldering.
3. When soldering board-to-board connectors, do not use too much force to avoid bending of the pins and showing unevenness on the pads.
4. Note that after the final welding is completed, you need to use a multimeter to measure the diode to check whether the welding is good. For example, whether there is any looseness or false welding of the pins, and if there is any phenomenon, the welding should be repeated.
