Terminal welding knowledge

Terminals of the welding conditions have strict requirements and professional standards, the material, specification, welding way through strictly controlled. Shenzhen jet electronic as a famous domestic terminal manufacturer, here to give you the most professional answer.
There is significant difference between the welding conditions, depending on the type of Terminal Blocks and welding process steps.Suitable for wave soldering, installed on the PCB terminals is a typical punch installation type.Perforation of welding pin must be accurate positioning, suitable size, balanced placement, and has good weldability, conducive to insert and welding.
In the process of the whole assembly, must withstand preheating zone, high temperature and wave soldering to the terminal body temperature.Flux may not affect terminal, must be easy to remove, there cannot be any residue.The whole assembly process must be clean with water.Preheat temperature often up to 100 ° C or higher, peak temperature of 280 ° C is also not uncommon.
Perforation of welding pin must be accurate positioning, suitable size, balanced placement, and has good weldability, conducive to insert and welding.In the process of the whole assembly must withstand high temperature shock produced by heat treatment, mainly used in welding ir preheat preheat and convection heat conduction to welding needle and tin interface with molten solder paste.
The sudden high temperature melt terminal, often distorted, blister and deformation.General component is so assembly time, a few minutes of exposure to the flux of time, a few minutes of preheating period, and the peaks of a few seconds, and cleaning and drying period of a few minutes.Choosing the right metal materials, resin can improve the reliability of terminal welding.
