Product Overview

Cooling Built Around Your Circuit Design

Electronic heat sinks are mechanical parts that must fit a PCB layout, a component height profile and an enclosure opening at the same time. We machine to your assembly drawing so the heat sink drops in without rework, and we can accommodate component cut-outs and standoffs in the same operation.

Zhigao is a manufacturer of electronic profile heat sink cnc machining serving customers in Europe, North America and Asia. Every order is produced to your drawing and inspected against your specification before shipment, with full documentation supplied.

Frequently Asked Questions

Can the heat sink be electrically insulated from the PCB?
Yes. The anodic oxide layer formed during anodizing is electrically insulating, and we can also supply insulating pads where higher dielectric strength is needed.
Can you machine mounting holes for specific components?
Yes. Send us your PCB layout or mechanical drawing and we will machine standoffs, clearances and screw holes to match.
What tolerance do you hold on machined features?
We hold +/-0.02mm on machined features such as holes, slots and mounting faces.
Do you supply thermal interface material?
Yes. Thermal pads, phase change material and thermal compound can be applied or supplied separately.
What is the minimum order quantity?
We accept orders from 1 piece for prototypes and sample validation.
How is the product packed?
Each heat sink is protected with film and EPE foam, then packed in export cartons or plywood cases.
