The Aluminium-Kühlkörper für Seeed Studio XIAO combines 2.0 mm fin pitch with 1.0 mm stock in 6061-T6 aluminium, so 20 x 20 x 10 mm parts keep 0.05 mm over 100 mm on the mounting face. Thermal resistance is 0.35 K/W, measured at CMM 0.001 mm resolution per lot.
Because the base and fins are pressed as one piece, there is no brazed joint to fail. 0.05 mm over 100 mm flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.
A single 160 T stroke forms the whole Aluminium-Kühlkörper für Seeed Studio XIAO, so part cost stops scaling with complexity. Tooling runs ±0.05 mm, and the 8 s cycle feeds a 120,000 pcs line.
The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between 6061-T6 aluminium and the airflow except the stamped surface itself.

Stamped construction tolerates batch variation better than extrusion: die wear shows up first as a measurable shift in fin pitch, which inspection catches at CMM 0.001 mm resolution rather than in the field.
One supplier now covers 1.0 mm to 1.0 mm fin gauges from the same 160 T press family, so a thermal redesign is a tooling change rather than a new vendor.
The standard material is 6061-T6 aluminium, supplied with zinc-nickel plating, trivalent passivation. For applications where EV and OBC charger exposure is a concern, we recommend the passivated route; where conductivity matters more than weight, copper C110 raises thermal performance and roughly doubles unit mass.
General dimensions run to ±0.10 mm, with critical features such as ±0.03 mm on fin pitch held separately. Formed geometry inherits tooling repeatability of ±0.05 mm, and hole position is held to ±0.10 mm. Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.
Each batch carries a CMM report from CMM 0.001 mm resolution. We record flatness, pitch, base thickness and hole position, and flag anything outside ±0.10 mm before it leaves the line.
Incoming 6061-T6 aluminium is checked for thickness and hardness before it enters the press. After forming, CMM 0.001 mm resolution confirms 0.05 mm over 100 mm and 2.0 mm against the drawing.

Flatness is measured on granite rather than on cast iron, because 0.05 mm over 100 mm at 20 x 20 x 10 mm reads differently on a plate that has not been lapped. Records keep both readings.

Final containment is PE bag + export carton, 20 kg per carton. Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.

EV and OBC charger programs are the reason this geometry exists. Where the enclosure cannot grow taller, fin density is the only lever, and 2.0 mm pitch with 1.0 mm stock is the practical ceiling for aluminium.
EV and OBC charger customers typically specify 6061-T6 aluminium for corrosion reasons and then hold the drawing to ±0.10 mm. The 120,000 pcs line absorbs the volume without a second source.
EV and OBC charger packaging and vibration rules push toward one-piece construction. A stamped Aluminium-Kühlkörper für Seeed Studio XIAO has no adhesive to creep, which is the usual failure mode in two-part coolers.
EV and OBC charger designs often run a 2.0 m/s forced-air path. 0.35 K/W at ΔT = 60 K, natural convection means EV and OBC charger can hold its target with fan power below the acoustic limit.

Every lot is inspected with CMM 0.001 mm resolution, and the report is included in the shipment. We check 0.05 mm over 100 mm, 2.0 mm, 1.5 mm and hole position against ±0.10 mm. Lot traceability from coil to carton is kept for 10 years.

Prototype is 7 working days from drawing approval; production is 12 working days after the first article is signed off. Tooling for a new part takes . We quote FOB Shenzhen, and sea freight to Europe runs about 25 to 30 days after booking.
The family covers 20 x 20 x 10 mm, with unit weights from 280 g. Because the base is pressed, new sizes are a die insert change rather than a new press line, so development is usually 2 weeks rather than 8.

Standard packing is PE bag + export carton, 20 kg per carton. We quote FOB Shenzhen. Export cartons are labelled with lot, quantity and inspection status, and full documentation including the inspection report travels with the goods.
The key is avoiding a second metal at the wet contact area. We recommend zinc-nickel plating, trivalent passivation and, where the part touches an aluminium chassis, an isolating washer. Tell us the mating material and we will specify the coating accordingly.
Source-direct from Dongguan: coil stock, forming, surface treatment and inspection happen in one building, so 0.05 mm over 100 mm flatness is verified before the part is packed.
Our EV and OBC charger experience runs back to the first tooling programme in 2015. That history is why the standard zinc-nickel plating, trivalent passivation and ±0.10 mm are conservative rather than optimistic.

We quote FOB Shenzhen and hold 50 pcs for sampling. Sampling is sample fee 30-80 USD, so a first evaluation does not require a production commitment.
