How to judge the sintering quality of electrode paste
If it is found that the surface of the lowered electrode is grayish white, dark but not red or reddish, it means that the baking is good. It can also be judged according to the smoke from the electrode when the electrode is put down. For example, a small amount of white smoke on the electrode that is put down is normal, no smoke is overburning, and thick smoke is underburning. In addition, you can also use the round steel to test the electrode that has just been put down on the lower edge of the copper tile.
