aluminum heat sink for seeed studio xiao
Key Takeaway
Aluminum heat sink for Seeed Studio XIAO uses copper-alloy CuZn37 with 0.5 mm fin thickness, 1.5 mm fin pitch, and 0.85 K/W thermal resistance. Black anodize Type II at 10-15 µm and general tolerance ±0.10 mm are standard. Lead time is 10 working days, with capacity from 50 to 50,000 pieces, and tooling designed around measured process capability rather than inspection filtering.
Whether you need 50 pieces for validation or 50,000 for a production line, aluminum heat sink for seeed studio xiao follows the same physics. What changes is which process window we hold, and how much inspection we put behind it.

Market and Technical Context
Consolidation among 1U server and AI accelerator buyers means fewer, larger programs. That rewards suppliers who can document process capability at 300,000 pcs rather than those who win on a single sample.

Tariff and logistics uncertainty has made regional qualification a priority in 1U server and AI accelerator. Buyers increasingly ask for a second qualified source, which changes how aluminum heat sink for seeed studio xiao is specified and how tolerances are documented.
How We Manufacture It
Tooling is designed around the measured capability of the process, so ±0.10 mm is a consequence of tooling geometry rather than an inspection filter. That is why 10 working days is realistic instead of optimistic.

In production, aluminum heat sink for seeed studio xiao runs with in-process checks at fixed intervals. Operators log dimensions every 30 to 50 pieces, which catches tool wear before the batch drifts outside ±0.10 mm.

Deburring and edge conditioning are specified on the drawing for aluminum heat sink for seeed studio xiao. A sharp edge that passes dimensional inspection can still fail assembly, so edge break is a controlled parameter rather than a cosmetic one.

Material and Surface Finish
copper-alloy CuZn37 is the default for aluminum heat sink for seeed studio xiao because it holds ±0.10 mm predictably and machines without work hardening surprises. Alternatives are quoted when corrosion or conductivity dominates the requirement.

Substitution requests are common when copper-alloy CuZn37 goes on allocation. We qualify any substitute against the same ±0.10 mm and black anodize Type II, 10-15 µm criteria before shipping, and provide the certificate with the change.
Compare it with High Power IGBT Heat Sink.
Recycled content and RoHS/REACH declarations are available for aluminum heat sink for seeed studio xiao on request. If your 1U server and AI accelerator customer audits material origin, ask for the mill certificate at quote stage, not at delivery.
Tolerance and Inspection
General dimensions on aluminum heat sink for seeed studio xiao are held to ±0.10 mm; critical features are identified on the drawing and controlled separately with a tighter band.
First-article inspection for aluminum heat sink for seeed studio xiao reports every dimension on the drawing, not a sample of them. That report is the reference for the rest of the batch and for any future reorder.
Process capability is tracked per feature. Where Cpk falls below the agreed threshold on aluminum heat sink for seeed studio xiao, we either adjust the process or reclassify the feature, rather than sorting parts at the end.
Where It Is Used
Service environment drives more redesigns than load does. aluminum heat sink for seeed studio xiao in outdoor or washdown service needs black anodize Type II, 10-15 µm and sealing considered at design stage, not added later.
Retrofit requests are common: an existing assembly needs aluminum heat sink for seeed studio xiao in a slightly different size. Because the process window is already known, 10 working days on a retrofit is usually shorter than on a new part.
What to Confirm Before Ordering
Define critical features at quote stage. Moving a feature from general ±0.10 mm to critical after tooling adds cost and extends 10 working days, which is the most avoidable delay in custom sourcing.

Packaging is part of the specification. Parts arriving with edge damage or mixed lots cost more than the packaging difference, especially for aluminum heat sink for seeed studio xiao with finished surfaces.
FAQ: Your Questions Before Ordering
What tolerance can you hold on aluminum heat sink for seeed studio xiao?
Prototype quantities start well below production minimums. Production runs for aluminum heat sink for seeed studio xiao start at 2000 pcs, which is where the process window is proven and unit cost stabilises.
What is the minimum order quantity for aluminum heat sink for seeed studio xiao?
Standard lead time for aluminum heat sink for seeed studio xiao is 10 working days after drawing approval and tooling sign-off. Prototypes are typically faster because they bypass tooling, and repeat orders are faster still because tooling exists.

What surface finishes are available for aluminum heat sink for seeed studio xiao?
black anodize Type II, 10-15 µm is standard for aluminum heat sink for seeed studio xiao. Other finishes are quoted with a defined thickness range and verified on a coupon from the same batch rather than assumed from process settings.
Can you prototype before tooling?
Yes, and we recommend it. Prototyping aluminum heat sink for seeed studio xiao without tooling validates fit and function at a fraction of tooling cost, and usually surfaces a design change before steel is cut.
How do you handle a design change mid-program?
Changes are documented against the original first-article report. We identify which dimensions are affected, requote only the affected operations, and tell you whether existing stock of aluminum heat sink for seeed studio xiao remains usable.

Frequently Asked Questions
What is the thermal resistance of this aluminum heat sink for Seeed Studio XIAO?
The thermal resistance is 0.85 K/W, based on the copper-alloy CuZn37 construction with 0.5 mm fin thickness and 1.5 mm fin pitch. This value is measured under standard conditions and should be confirmed for your specific airflow and mounting configuration.
What material and surface finish do you use?
We use copper-alloy CuZn37 with black anodize Type II at 10-15 µm. This combination provides corrosion resistance and consistent thermal performance. The general tolerance is ±0.10 mm, and the finish is suitable for most Seeed Studio XIAO enclosure and mounting requirements.
What is the lead time and minimum order quantity?
Lead time is 10 working days, and the minimum order quantity is 50 pieces. We can scale to 50,000 pieces for production lines. The same physics apply across volumes; only the process window and inspection level change.
Can you support a 300,000-piece program?
Yes. We document process capability at 300,000 pcs, which is increasingly required by 1U server and AI accelerator buyers. Our tooling is designed around measured capability, so ±0.10 mm is a consequence of tooling geometry rather than an inspection filter.
Do you offer a second qualified source?
Buyers often request a second qualified source to reduce supply chain risk. We can provide documentation and inspection records to support dual sourcing. This changes how the aluminum heat sink for Seeed Studio XIAO is specified and how tolerances are documented.

How do you ensure tolerance and quality?
Tolerance is held at ±0.10 mm through tooling designed around measured process capability. We inspect fin thickness, pitch, and coating thickness, and record inspection data per lot. This approach supports consistent quality from 50 to 50,000 pieces.

What should I confirm before ordering?
Confirm your required thermal resistance (0.85 K/W), material (CuZn37), finish (black anodize Type II, 10-15 µm), tolerance (±0.10 mm), quantity (50 to 50,000 pieces), and lead time (10 working days). Also clarify whether you need a second qualified source or regional qualification documentation.
