贴片电解电容焊不住是什么原因和改善方法

贴片电解电容
焊不住是什么原因和改善方法
贴片电解电容的的引脚上没一点焊锡在才会脱落.这种现象都是手工焊接才会这样.因为手工焊接电解电容的大部分焊点在底部很容易造成假焊.
电解电容焊接不住的改善方法,把焊盘做的大一点,增大焊点与线路板的接触面积. 或者先给焊盘上锡,再放贴片的电解电容,焊接。让引脚底部能被焊接上.
贴片电解电容
手焊确实麻烦,

因为大部分焊点在底部,你要想办法全部焊上机械强度才高
先把贴片电解电容引脚镀锡,焊盘镀锡,放上电容,然后烙铁长时间加热,让锡全部熔化,有热风枪的话,用热风枪吹比较方便.
先往贴片电解电容的两个焊盘上沾好锡,然后再焊在各方也是个方法
贴片铝电解
适合机器焊,如果不上机的话,选插件的吧.
