Verfahren zur Erzeugung von Lothügeln auf einem Substrat |
摘要 |
In a method of producing solder bumps on a substrate by contact with a molten solder bath, at least part of the substrate is cooled during contact with (preferably immersion in) the solder bath. Preferably, the substrate is a chip or wafer and is briefly dipped into the solder bath or wetted by a solder wave. |
