Quality rosin, the circuit board soldering helpful. When the tip or element surface oxidation, easy on the tin and welding, stick with a soldering iron rosin can be quickly removed after oxidation, the element becomes easy to weld.
Rosin use of knowledge:
1. Use rosin, solder will prettier, with solder joints will be black.
2. The circuit board is preferably solder with rosin soldering, because the flux is rosin. But not too much, a little on the line, the beginner will master the poor maintenance of propriety, often welding weld like a tin can spot big nor too small, to look at the solder joints on the board. Now all of the welding machine board, individual artificial welding, and welding current is relatively large areas are relatively high voltage areas. Look at the old electronic products or old-fashioned black and white TV with a manual welding. Look good, but strong. No open welding. Late eighties basically welding machine, also known as wave soldering, faster and better, but a little more current big place open welding. Solder paste difficult only when the tin and other items used in iron, corrosive, generally only use rosin on the line, the role of rosin solder oxides precipitated protect the solder from oxidation and increase the mobility of solder .
3. Electronic components are generally Shanghao tin, if rust first scrape off, put on the rosin with a soldering iron hot, and then on the tin. After the circuit board can be directly plugged in already scraping the bright tin rosin core solder wire welding element. Before rosin soldering iron to remove the volatile finish, dip again if sticky rosin solder, solder solidification front moving elements do not.
