Connectors not eat tin is the reason? I do? If you exclude the welding process issues, such as solder temperature, suitable flux, low-cost high-temperature line motor 3302, over soldering time, do not eat tin may be contact surfaces caused by oxidation or dirty, pay attention to open the package as soon as possible after use, the storage environment to keep dry. There is a bad product coating, substrate exposed, high-temperature line motor 3302 original, will result not eat tin. It should first determine what is causing. If the process issues, it is necessary to improve the process, for example, choose a suitable flux, set the corresponding solder temperature, adjust the furnace time (reflow), or chain speed (wave) and the like; if pins are dirty, Targeted need cleaning; if it is oxidation problem (basically no solder eat, motor 3302 hot line, or even if there is no infiltration of state tin) more trouble, high-temperature line wholesale motor 3302, and now there is no good reducing the oxide layer removed, 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.
