Dongguan light touch switch in use and welding need to have temperature requirements, what are the specific requirements? Let's give you a detailed introduction.
Dongguan light touch switch is a key parameter relative to the material that needs welding. It is equivalent to the temperature of ferrochrome. If the temperature is not enough, it can not be welded. Excessive temperature will cause raw materials to burn or lead to structural damage, which will lead to the strength deterioration. Each company chooses different transducers, the output amplitude of the transducer will fluctuate. By adapting different ratio horn and welding head, the working amplitude of the welding head can be calibrated to meet the requirements.
The output amplitude of common transducer is 10-20 micron, and the working amplitude is generally about 30 micron. The ratio of horn and weld head is related to the shape of horn and weld head, the ratio of front to back area and other factors, such as exponential amplitude, functional amplitude, step-type amplitude, etc., which have a great influence on the ratio. The ratio of front to back area is proportional to the total ratio. The welding machines of different brands are selected. The simplest method is to make the welded joints according to the proportional size of the welded joints, which can ensure the stability of the amplitude parameters. The bonding strength of Dongguan light touch switch meets the requirement temporarily, but the epoxy resin of organic material decreases with the aging of time, the micro-switch reduces the bonding strength, and the lead may fall off potentially in the long-term use, which may cause the breaker to fail in operation.
In order to solve these problems, we look for a kind of Dongguan light touch switch material, which is suitable for the connection between sheet lead and electrodes. It has high strength, simple technology, easy control of material dosage, beautiful appearance, and does not affect the performance of capacitors. Through repeated tests, 62Sn/36Pb/2Ag paste solder paste was selected for welding positioning, and many tests and performance tests were carried out.
