Heatsinks with lock-in transistor retaining springs
10 March 2004Manufacturing / Production Technology, Hardware & Services
Simplified transistor fastening on heatsinks with a reduction in cost is possible using a new series of extruded heatsinks and lock-in springs made by Fischer Elektronik. The special geometry of the groove in the heatsink allows easy transistor fastening with a specially shaped stainless steel spring that is simply snapped in.
This type of fastening ensures a firm hold for almost all versions and sizes of transistor cases (TO220, TO218, TO247, etc), diverse SIP multiwatt and MAX types without holes. The special geometry of the groove in the heatsink in combination with the retaining spring ensures optimum heat transfer between the component and the heatsink.

Editor's Choice Manufacturing / Production Technology, Hardware & Services
Dross formation is an inevitable consequence of wave soldering. It occurs when molten solder comes into contact with oxygen, forming metal oxides that float on the surface of the solder bath. Over time, this oxidation byproduct accumulates and must be removed to maintain solder quality and process consistency.
