The base is machined from 6063 aluminum with a flat TEC face and drilled clamp holes, grooved on the fin side. Aluminum fins are cut, bonded with thermal epoxy and cured under load; the TEC face is fly-cut after bonding so clamp pressure lands evenly, and the part is cleaned and packed with the face protected.
Takes screw pressure without bowing.
Convects with no fan or a small one.
Clamp screws sit outside the TEC footprint.
Even contact under the module.
Fits the instrument, not the bench.

| Capacity | 60,000+ thermal parts per year |
| Lead Time | Samples typically 7-15 days; production scheduled to volume |
Note: values above are KingKa build options and verified capability; final geometry, holes and finish are confirmed against your drawing.
Clamp load is the hidden spec: a base that bows under the screws lifts the module edge and adds contact resistance, which is why base thickness is set by stiffness and the face is cut after bonding.
Design & CFD. 3D layout with CFD review sizes the fin field, pipe route and base thickness to the load and airflow.
Base machining. Plate, pockets and pipe channels are milled on 50+ CNC centers to +/-0.005 mm.
Fin and pipe joining. Fins skived, stacked or extruded; pipes pressed and soldered; the stack joined to the base by the process the design calls for.
Face fly-cutting. Contact face machined flat after joining so the part sits true on the device.
Final inspection. Hexagon CMM (+/-0.001 mm) and 2.5D projector check critical features; 4-stage IQC / IPQC / FQC.
Fin pitch and height - measured against the drawing before packing.
Base flatness - fly-cut face checked on the contact side.
CMM report - critical dimensions to +/-0.001 mm.
Joint inspection - solder or weld fillet checked along the stack feet.
Visual and batch audit - IQC / IPQC / FQC on every run.
TEC hot-side sinks are specified by clamp load and air, not by wattage alone:
TEC cooling assemblies
Laser temperature control
Laboratory instruments
Portable coolers
Sensor cold stages
Send the TEC footprint, the module stack height, the clamp method and the ambient. KingKa sets base thickness for the clamp load and fin pitch for the air that is actually available.
KingKa is a direct manufacturer with 16+ years in thermal production, 50+ CNC centers, in-house skiving, FSW and vacuum brazing, certified to ISO 9001:2015 and IATF 16949:2016.
Send the clamp method with the drawing - screws, spring clips and bars load the base differently, and the thickness that works for one is wrong for another.
One supplier for the whole assembly. Base, fins, pipes and hardware under one quality system.
CFD before tooling. Design review catches a bad layout before metal is cut.
Prototype to volume. Samples in 7-15 days, production scheduled to forecast.
