inSMTDuring the post-furnace testing, it is often found that the current does not pass through frequently. After the solder pad is tested with a multimeter for a path, it is discovered that only when the layer of keratin on the upper surface of the solder pad after passing through the furnace is removed will there be a path. Then,SMTThe conductivity of solder paste after soldering is poor. How should we deal with this problem? Now, Shenzhen JJY Solder Paste Manufacturer will explain: First, try to reduce the residue of solder paste. It is recommended to choose no-rinse solder paste. Second, it must be cleaned before conducting the test......

Solder paste is an indispensable soldering material in the electronics industry. It is a gel-like substance made by mixing metal powder, solder paste and solvent, and is used to attach electronic devices toPCBThe plates are joined together to form firm weld points. Syringe solder paste is a kind of professional solder paste. It is made by filling the solder paste in a syringe and precisely controlling the amount and position of the solder paste through a dispensing machine or manual operation. It is applicable to the soldering of various surface mount electronic devices, such as capacitors, resistors, diodes, transistors, and integrations......
