From drawing approval
All skiving is done on a dedicated 3-axis CNC machine with a custom carbide tool.
We control tool wear by measuring fin thickness every 50 pieces.
Deburring is manual, then verified under magnification.
You get a dimensional report per batch, not just a box of parts.
Three reasons buyers send us their drawings
1. Batch-traceable quality.
Every heatsink gets a unique batch number.
We store material certificates, tool settings, and inspection data for each batch for 3 years.
If a field failure happens, you can trace it back to the exact copper lot and machine run.
That is not common for custom heat sinks made in China, but we do it as standard.
Material mill certificate
Dimensional measurements (key features, 5 samples per batch)
Flatness and roughness readings
Photos of the actual parts
The report is signed by the QC lead.
If any dimension is out of tolerance, we reject the batch before it ships.
You do not have to re-inspect everything on arrival.
3. One factory for CNC, stamping, springs, and heatsinks.
BQUQ runs four production lines under one roof.
Your heatsink might need a stamped clip, a CNC-machined base, or a spring for mounting.
We make all of them in-house.
No third-party coordination, no shipping delays between suppliers.
One purchase order, one quality standard, one responsible engineer.
Where these parts are used
IGBT modules in inverters and motor drives
Laser diode mounts and optical transceivers
High-power LED arrays in stadium lighting
CPU and GPU coolers for servers
Medical imaging equipment (CT, MRI power supplies)
RF power amplifiers in telecom base stations
Skived fins give you a solid base with no thermal interface between fins and base.
That means lower thermal resistance than stamped or bonded fin stacks.
For a 100 mm x 100 mm base with 20 mm fins, you can expect thermal resistance around 0.25 °C/W at 2 m/s airflow.
If you need a specific simulation, send us your boundary conditions.
Q: What is your MOQ?
A: None. We accept one-piece prototypes and scale to 10,000 pieces.
The unit price is higher for small batches, but the process and inspection are identical.
Q: How do you control tolerance and quality?
A: We use CMM and optical comparators for critical dimensions.
Flatness is checked on a granite plate with a dial indicator.
Each batch gets a dimensional report.
If you need first-article inspection (FAI) per AS9102 or PPAP, we can do that too.
Q: What is the lead time for custom heat sinks?
A: Prototypes (1–10 pcs) ship in 10–15 working days after drawing approval.
Production runs (100+ pcs) take 20–25 working days.
For urgent orders, we can split the batch and air-ship the first 20 pieces.
Q: Can you provide material certificates?
A: Yes. We supply mill certificates for all copper grades.
C1020 is oxygen-free copper with 101% IACS conductivity.
C1100 is electrolytic tough pitch copper, 100% IACS.
We also provide RoHS and REACH declarations if required.
