Lead in solders for the soldering to machined through hole discoidal and planar array ceramic multilayer capacitors.

通孔盘状及平面阵列陶瓷多层电容器焊料所含的铅；

I endeavoured to unhasp the casement，but the hook was soldered into the staple.

我试着那窗子，但窗钩给焊在钩环里了。

For instance, you should make sure that the insulations between the soldering tweezers and welding cable are ok and the earthing point and each termipoint of soldering machine are in good condition.
