Today, we will introduce the packaging and welding method of touch switch. We will give you detailed details below.
Light touch switch is widely used. As long as the hand is released, the light touch switch will automatically disconnect. At present, it is used in digital products, household appliances, laser pen keys, computer products and so on. So how to package and weld the light touch switch? Let's learn about it.
Packaging and welding method of touch switch:
1. Wave soldering of pins has the advantages of low price, time-saving and labor-saving. The disadvantage is that as the components become smaller and smaller, PCB becomes denser and denser, the possibility of bridging and short-circuit between solder joints increases.

2. Reflow soldering of patches has the advantages of easy control of temperature, avoidance of oxidation during welding and easier control of manufacturing cost. The disadvantage is that solder collapse also occurs during welding heating, which occurs in preheating and main heating situations. When preheating temperature is in the range of tens to 100, solvents, as one of the components of solder, will reduce viscosity. If the outflow tends to be strong in the lower part, the solder particles will be extruded out of the gold-bearing particles outside the welding zone at the same time. If the solder particles can not be returned to the welding zone during melting, the retained solder balls will also be formed.
3. The advantage of manual welding is that it can accurately grasp the welding of each component, but the disadvantage is that it is too time-consuming and laborious.
