      電烙鐵可分為幾種類型

      1.電烙鐵分為外熱式和內熱式兩種,外熱式的一般功率都較大。   內熱式的電烙鐵體積較小,而且價格便宜。一般電子制作都用20W-30W的內式電烙鐵。當然有一把50W的外熱式電烙鐵能夠有備無患。內熱式的電烙鐵發熱效率較高,而且更換烙鐵頭也較方便。 
            電烙鐵是用來焊錫的,為方便使用,通常做成“焊錫絲”,焊錫絲內一般都含有助焊的松香。焊錫絲使用約60%的錫和40%的鉛合成,熔點較低。
            松香是一種助焊劑,可以幫助焊接,拉二胡的人肯定有吧,聽說也可到藥店購買。松香可以直接用,也可以配置成松香溶液,就是把松香碾碎,放入小瓶中,再加入酒精攪勻。注意酒精易揮發,用完后記得把瓶蓋擰緊。瓶里可以放一小塊棉花,用時就用鑷子夾出來涂在印刷板上或元器件上。

      2、使用電烙鐵應該注意的問題? 新的電烙鐵在使用前用銼刀銼一下烙鐵的尖頭,接通電源后等一會兒烙鐵頭的顏色會變,證明烙鐵發熱了,然后用焊錫絲放在烙鐵尖頭上鍍上錫,使烙鐵不易被氧化。在使用中,應使烙鐵頭保持清潔,并保證烙鐵的尖頭上始終有焊錫。使用烙鐵時,烙鐵的溫度太低則熔化不了焊錫,或者使焊點未完全熔化而成不好看、不可靠的樣子。太高又會使烙鐵“燒死”(盡管溫度很高,卻不能蘸上錫)。另外也要控制好焊接的時間,電烙鐵停留的時間太短,焊錫不易完全熔化、接觸好,形成“虛焊”,而焊接時間太長又容易損壞元器件,或使印刷電路板的銅箔翹起。一般一兩秒內要焊好一個焊點,若沒完成,寧愿等一會兒再焊一次。焊接電烙鐵不能移動,應該先選好接觸焊點的位置,再用烙鐵頭的搪錫面去接觸焊點。機維修中,經常要更換電路板上的元件,需要使用電烙鐵,且對它的要求也很高。這是因為手機的元件采用表面貼裝工藝,元器件體積小,集成化高,印制電路精細,焊盤小。若電烙鐵選擇不當,在焊接過程中很容易造成人為故障,如虛焊、短路甚至一些大器件如屏蔽罩的焊接,要采用大功率電烙鐵,所以還要準備一把普通的60W以上的粗頭電烙鐵。

      3、常見的電烙鐵的規格有哪幾種?
            常見電烙鐵的規格有:30W,45W,60W,等等的!
