無鉛焊錫絲炸錫、爆錫造成的原因和解決方案

什么是炸錫?

炸錫是指在焊接作業時,高溫烙鐵頭碰到焊錫絲時,會發出一種炸裂的聲音,同時會彈出一

些色澤光亮的小錫珠固體金屬,這就是炸錫現象。

炸錫的原因

表面原因:
1.受潮水份的問題:

由于空氣中存在水分,特別是春天雨多,潮濕的天氣,容易使焊錫絲或電路板因為保管不周或不

妥而受潮,附有水份在表面,這種可能會引發斷續性的炸錫或爆錫現象。

2.焊錫絲加工的問題:在生產焊錫絲過程中,經過拉絲機時,焊錫絲如有裂縫,拉絲油會隨裂縫滲入,


也是引發焊接作業時炸錫現象的發生。

主要的原因:

最主要的原因是由于焊錫絲的結構造成的,只有認識到這一點才能真正的解決問題所在,焊錫絲的結構

是錫在外面,焊錫絲內有一小管道是填充滿助焊劑的。在焊錫的時候,如果高溫烙鐵頭碰到焊錫絲,焊

錫絲內的助焊劑會迅速融化產生大量氣泡炸開,因為焊錫絲管道是密封的,產生的大量氣泡引起高壓,

壓力大于管道的壓力時,形成將焊錫炸飛,從而形成爆炸。

如果您買到這類焊錫絲,一定會及時反饋給焊錫絲供應商,讓他們改善這種現象,否則炸錫后殘留多,還得

需要清洗。

  華金金屬是專門生產焊錫絲的廠家,采用云南原礦精錫作為原材料,所生產的焊錫絲產品質量穩定,焊點飽

滿光亮,焊接飛濺少,無需清洗。

如果您需要采購焊錫絲產品記得來華金金屬哦,華金金屬二十年專業生產焊錫絲,質量穩定,廠家直銷,價格

優勢。
