Embodiment 1
[0017] Embodiment 1: Taking the pin welding of an interface device with multiple pins arranged in the same direction as an example, a welding method of component pins can be described in detail. Solder to the circuit board. The welding method includes the following steps:
[0018] Step 1: Place the components on the circuit board to be soldered, and use the spray gun to draw solder paste strips on each pin along the direction perpendicular to the pin arrangement direction of the components.
[0019] Step 2: Put the circuit board and components into an oven for baking, and the temperature of the oven is lower than the melting temperature of the part with the lowest melting point in the components and circuit board. Usually, the lowest melting point part of the component or circuit board that is not resistant to high temperature is made of plastic, so low temperature baking is used in this step, and the baking temperature is lower than the melting temperature of the plastic, wh...
