Custom Skived Heat Sink with Cut-outs

Many projects do not need a plain rectangular sink. They need one that clears capacitors, connectors and harnesses while still leaving room for a screwdriver. These parts are skived first, then milled for clearance and steps.

Sequence matters

Skiving before milling risks distorting the fins during clamping; milling first limits where the fins can go. We choose the sequence per outline complexity and add temporary supports between fins to avoid clamp marks.

Sampling

For irregular parts we suggest one or two samples first, checking fin-to-component clearance and whether the counterbore is deep enough for tool access.

Process notes

Drawing review, process sequencing, clearance slot and step machining, support removal, deburring, surface finishing, trial assembly.

Applications

Power supply internals, inverters, automotive controllers, complex industrial equipment.
