回流焊注意事項(xiàng)(Warning for Reflow )
1、建議焊錫膏涂抹厚度最大為0.25mm, 過多錫膏可能會(huì)造成短路,特別是手工焊接
(The printed solder thickness is not over 0.25mm,Excess solder may cause a short circuit, especially during hand soldering)
2、如果回流焊溫度超過建議值,組件可能被損壞
(If reflow temperatures exceed the recommended profile, devices may not meet the performance requirements)
3、該器件不適合波峰焊,如果是手工焊接或浸焊請(qǐng)聯(lián)系制造商TLC給予建議
(Device can not be wave soldered. Please contact TLC for hand soldering and dip soldering recommendations.)
4、使用回流焊時(shí),不可將組件置于電路板之背面/底面-組件不可與溶劑直接接觸
(Device can’t contact solvent)
注意(Note):所有溫度皆為組件表面之測(cè)量值 (All temperature in top chart is measured on the surface of devices)
