Clip-on heat sink / finger-style heat sink for transistors

Clip-on heat sink as a stamped and formed part for transistor packages (e.g. TO-220): the heat sink slides onto the component, the integrated retaining clip secures it mechanically and ensures thermal contact. The protruding cooling fingers maximize surface area per volume and dissipate low to medium power losses directly on the printed circuit board.

Material: Copper alloy CuSn4, tin-plated · 0.6 mm

Häufige Fragen zur Fertigung: Clip-on heat sink / finger-style heat sink for transistors

You can produce Clip-on heat sink / finger-style heat sink for transistors on the FMS-Q 80 RS and FMS-Q 120 RS. The FMS-Q 80 RS works with 80 kN punching force, strip material up to 50 mm width, wire up to 4 mm. At up to 400 parts per minute, the machine is designed for series production — finished parts come straight off the machine.

The radial design positions the bending slides freely through 360° around the central bending core — ideal for parts like Clip-on heat sink with multiple bends in different directions. Tool changes take less than 30 minutes, so even smaller batches are economical.

Copper alloy CuSn4, tin-plated (0.6 mm) runs through the punch-bending machine as strip or wire stock in a progressive process: punching, bending, and inspection happen in one pass. Instead of buying parts from suppliers, you produce them in-house at significantly lower unit costs from medium quantities upwards — Biegema configures the machine specifically for your part.
