PCB soldering of reed components
Due to the presence of reeds in this type of component, if an external force is applied to the reed during the soldering of the pcb, the spring force of the reed is easily damaged, resulting in component failure.
Precautions for soldering of reed components:
(1) Reliable tin plating of components of pcb.
(2) The board cannot be applied to any direction of the component during assembly welding.
(3) The amount of solder should be small, otherwise it will cause the elastic force of the static contact piece in the reed component to change and the component to fail.
(4) The installation should not be too tight, otherwise the deformation of the reed will be invalid.
(5) The welding time should be short.
PCB soldering of ceramic capacitors, light-emitting diodes, mid-week and other components
The commonality of such components is that the temperature is too high during soldering, and the soldering time is too long, which may cause component failure and damage. The precautions for welding are as follows:
1) Reliably tin the components.
2) The heat can be dissipated by using a tweezers to clamp the leads.
3) The welding speed is fast, and it is not possible to repeatedly heat one lead.
PCB soldering method for micro components
Due to its small size, micro-components tend to cause lead adhesion during soldering. Precautions when welding:
1) The component leads should be soldered reliably.
2) Select a conical electric iron tip, and the tip should be as sharp as possible.
3) Select a table lamp with a magnifying glass.
