Introduction to the welding type of small micro switch

　　Welding type of small micro switch

　　1.The manual welding of small micro-switches has the advantage of accurately grasping the welding of each component.The disadvantage is that it is too time-consuming and labor-intensive.

　　2.Wave soldering of the pin,the price is low,saving time and effort.Disadvantages:As components become smaller and more densely packed,the possibility of bridging and shorting between solder joints has increased.

　　3.Reflow soldering of the chip,the advantage of this process is that the temperature is easy to control,oxidation can be avoided during the soldering process,and the manufacturing cost is also easier to control.The disadvantage of small microswitches is that solder sag occurs during solder heating,which occurs in both preheating and main heating fields.The small micro switch supply is combined.When the preheating temperature is in the range of tens to 100,the solvent which is one of the components in the solder will lower the viscosity and flow out.If the outflow tends to be strong,the solder will be simultaneously The gold-containing particles outside the particle extrusion weld zone,if not returned to the weld zone during melting,also form a retained solder ball.

　　Due to its small size,multi-gear position,and good driving force,it has been widely used in many fields such as household appliances.With the continuous improvement of people's living standards,the upgrading of these household appliances is getting faster and faster,and the number of them needs to be larger and larger.This is also the biggest potential direction for us to be optimistic about its development prospects.
