Thermacool Metal Core PCB Base Laminate material is an insulated metal clad substrate, comprising of three layers:
A base plate made of 1.5mm Aluminum at the bottom
100um dieletric layer (FR4) 100μm thickness, consisting of glass fabric combined with a mixture from epoxy resin and ceramic(s).
35μm thick copper foil on the upper side. Between the two layers there is an electrically isolating layer (FR4) 100μm thickness, consisting of glass fabric combined with a mixture from epoxy resin and ceramic(s).
The middle layer givers a very good thermal conduction at 1.6W/mK, a high dielectric strength and a continuous high temperature resistance.
Processing of this type of board is carried out in the conventional manner. There is only one difference: The Aluminum must be covered when developing or etching the board, in order to prevent contact between the aluminum and the developer or Etchant.
Common applications for this type of material are:-
- Ultra bright LED Substrate
- Power Conversion
- PDP, LED, Regulator for TV
- Monitor Drives
- Automotive electronics (Vehicle lightning, regulator, converters, power module)
- Rectifiers, Power Supplies
- Areas requiring high heat dissapation from the circuit
Supplied in 150 x 230mm size sheets, Other sizes available by request.
