Your drawing. Our machines. A heatsink that fits exactly where it must.
We are BQUQ, a precision manufacturing factory in Dongguan, China. 20 years on the floor. CNC machining, metal stamping, springs, and heat sinks under one roof. We make DC-DC module heatsinks from your PDF, STEP, or even a napkin sketch.
Every part is verified before shipment. Not sampled. Every batch.
| Parameter | Value | Notes |
|---|---|---|
| Material | Al 6061-T6, 6063-T5, 5052-H32, Cu C1100 | Lead-free, RoHS compliant |
| Machining | CNC 3-axis & 4-axis | Max part size 800×600×300 mm |
| Stamping | Progressive die, 25–160 ton | For fins, clips, brackets |
| Tolerance | ±0.05 mm (machined), ±0.1 mm (stamped) | Tighter on request |
| Surface finish | Anodize (clear, black, hard), Ni plating, tin plating | Thickness 8–25 μm anodize |
| Flatness | ≤0.1 mm over 100 mm | Critical for TIM contact |
| Roughness | Ra 0.8–1.6 μm on mating face | Optional mirror polish |
| Batch size | 1–100,000 pcs | No MOQ, tooling amortized per order |
| Inspection | CMM, 2D projector, thermal resistance test | Report per batch, PDF or hard copy |
| Lead time | 7–12 days prototypes, 15–20 days production | Air freight available |
1. Batch-traceable quality. Every heatsink gets a heat number and a QC stamp. You can trace the material lot, machine operator, and inspection date. If a field failure happens, we pull the batch record in minutes. No guesswork.
2. Inspection report per batch. You get dimensional data, surface finish readings, and thermal resistance values. Not a generic certificate. Real numbers from our CMM and thermal test rig. If we miss a spec, you know before it ships.
3. One factory for CNC + stamping + springs + heatsink. Your DC-DC module needs more than a heatsink. It needs a spring clip, a stamped baseplate, maybe a machined mounting block. We make all of it in-house. One PO, one quality system, one shipping address. No juggling three suppliers across time zones.
DC-DC module heatsinks from BQUQ go into:
If it converts DC voltage and gets hot, we’ve made a heatsink for it.

Q: Do you really have no MOQ? A: Yes. We run prototypes at 1–5 pieces. Production runs start at 100. Tooling cost is quoted separately and amortized if you repeat orders.
Q: What tolerance can you hold on a stamped heatsink? A: ±0.1 mm on stamped features, ±0.05 mm on CNC-machined surfaces. For critical mating faces, we can go to ±0.02 mm with a grinding pass. Ask us before quoting – we’ll tell you if it’s worth the cost.
Q: How fast can I get a sample? A: 7–12 days for CNC-machined prototypes. Stamped parts need tooling – 15–20 days for soft tool, 25–35 days for hard tool. We ship via DHL or FedEx.
Q: Do you provide material certificates? A: Yes. Mill certificates for aluminum and copper, RoHS and REACH declarations, and our own inspection report with dimensional and thermal data. All free with every batch.
