通常含鉛量高果o的錫線溶點較低;加左銀或銅o既溶點就高o的,要火數大o的先焊得好!作者: fbs 時間: 2012-4-16 17:35
The melting point is lowest when the ratio is 63/37. Why it is difficult to melt is the China wire is not use for electronic soldering and is only use for welding. For soldering, the wire should have flux core to help further lower down the melting point and clean the soldering point. You can go to hardware shop to buy a can of flux if you want to use up the existing China Tin/Lead wire.作者: BUNNYYUEN 時間: 2012-4-17 09:27
其實仲有一點好緊要既就系你焊線既位置的清潔問題,goot 的錫線的橫切面中間是松香油,此松香的作用是幫你清潔焊面與焊點之間金屬的清潔作用,如你在焊缐或焊點/面時再塗上多一些松香膏/或油的話會事半功倍,而大陸仔的錫線通常含鉛比較多和沒松香,所以比較難上錫作者: 86j 時間: 2012-4-18 20:56
