Connectors not eat tin is the reason? I do? If you exclude the welding process issues, such as solder temperature, suitable flux, solder over time, do not eat tin oxide contact surfaces may be caused or dirty, Note that you should use as soon as possible after opening the package, the storage environment to keep dry. There is a bad product coating, substrate exposed, can also cause eating tin. It should first determine what is causing. If the process issues, it is necessary to improve the process, for example, select a suitable flux adequate supply of the motor Cable line, set the corresponding solder temperature, adjust the furnace time (reflow) Motor Cable line market price, or chain speed (Wave) and so on; if it is dirty pins, it needs targeted cleaning; if it is a problem oxide (basic Solder eat no motor Cable line market, or even if there is no infiltration of state tin) more trouble, have not yet good reducing agent to remove the oxide layer, you may want to consider scrapping, in practice, in the case of small quantities of some companies after scraping the oxide layer welding methods, but the reliability of this approach has not been verified. Because now need to use the connector to the appearance of fine products, ease of installation and long life direction, there is a pin row female connector of a good solution to this connector uses the needs of manufacturers, Pai Pai mother Connector become many manufacturers of all ages use the connector, after a number of related tests. Motor Cable wire shelf, Xu Chong-electronic products factory, motor Cable line consists of Dongguan Shijie Xu Chong-electronic products factory provided.
