The principle of welding ERSA wave solder: It is to let the circuit board of the inserted or mounted components contact the wave crest of the molten solder to realize continuous automatic welding. Double wave soldering: There are two wave crests in front of the solder pot, the former one is narrower (the ratio of crest to wave width is greater than 1).
There are 2-3 staggered small peaks at the peak end. Under the action of such a turbulent wave that continuously and rapidly flows up, down, left and right, the gas generated by the welding heat is eliminated, and the surface tension effect is also weakened, so as to obtain a good welding. The latter wave peak is a two-way wide flat wave, and the solder flow is flat and slow, which can remove excess solder, eliminate burrs, bridges and other undesirable phenomena.
In 2009, Shenzhen wenzhan Technology Co., Ltd. was established to build a more timely and effective communication platform, and realize the company's service tenet of serving leading customers.The engineers of the company are professional technicians who have been certified by the original factory for more than 10 years. They always adhere to the value of putting the interests of customers first, and provide customers with high-quality equipment accessories, consumables, fixtures and technical support services.
In order to effectively reduce the cost of customers, the company set up a machining plant, and changed most of the feeder parts to self-produced parts, so as to ensure sufficient inventory and reduce the cost of customers at the same time.
