Solder Wire SL-18 ROSIN

One of the most important tools in the electrical industry and e-Solder job is .Material fasteners, and the alloy of metal tin and lead is Solder called . In practice, Solder job by a device, the heat developer like soldering iron are done, i.e. by soldering iron, etc. the junction of the two metals to warm him up to the point of melting the solder to reach the solder to protect the connection applied and after cooling, two pieces together are are.As was said solder alloy of tin and lead is based on the percentage of them in the alloy considered to be . If you click on the spool of solder in the look of your two numbers written on it is, for example, 60/40 this to mean that Solder Ultra has 60% tin and 40% lead.Basically, for the solder job on the e-must be from لحیمی be used in a hundred tin it 40 be . The reason is that the melting point of tin is less than. So what percentage of peak is more Solder in the air, only melts . The temperature, if high, causes the defective of semi-conductors like diodes, etc..... Can be, especially when ruining the printed circuit can also be . In addition, in an e-mail from the percentage of tin greater use . The best type of solder, etc. Solder, 63% is in the market of the same name, can be found .
