IMS PCB prototypes with Aluminium core

The abbreviation IMS stands for Insulated Metal Substrates. With IMS printed circuit boards instead of the usual base material, aluminium is used as the carrier for copper.

Aluminium core printed circuit boards are used for the thermal management of the circuit. High power LEDs are the most well-known example of it. In addition, parts for controls, power transducers etc. are often developed with IMS PCBs.



Presently we offer aluminium core printed circuit boards with the following technology in the IMS POOL:

  • 1.5 mm thickness
  • Isolation layer: 100µm
  • Copper: 35µm Cu singlesided

Soldermask & Silkscreen

Depending on whether light is to be absorbed or reflected, you can select between black or white soldermask.

Silkscreen colours of black and white are available in the aluminium core PCB-POOL® service.

Soldermask for one-sided printed circuit boards costs R114.55 (independent of size).

Silkscreen costs R114.55 (independent of size).

Mechanical processing

Would you like to mount your IMS (Insulated Metallic Substrate) PCB? No problem!

For an optional extra charge it is possible to integrate threads, counter-sunk drills and depth milling. Such data must be delivered separately and is only accepted by us in DXF or Target Front Panel Designer formats.
