Abstract
A power-electronic metal-ceramic module (10) comprising a metal-ceramic substrate (12) made of a ceramic carrier (14) having a metal top and bottom ply (16, 18), which is joined on or in the metal top ply (16) and/or the metal bottom ply (18) with a metal layer (16, 18, 22, 23) forming a frame (24) for accommodating at least one electronic component (30) and at least one electronic component (30) accommodated in the frame (24).
Claims9
Method for producing a circuit board module with integrated power-electronic metal-ceramic module, comprising the following steps to form a first layer sequence:
- providing a circuit board base frame made of metal-laminated circuit board carrier material, the circuit board base frame including a first recess for accommodating a power-electronic metal-ceramic module;
- inserting the power-electronic metal-ceramic module into the first recess in the circuit board base frame, the power-electronic metal-ceramic module comprising a ceramic carrier having a metal top ply and a metal bottom ply and a frame including a second recess accommodating an electronic component, wherein the frame is formed in the metal top ply or the metal bottom ply, or wherein the frame is formed in a metal layer applied to the metal top ply or the metal bottom ply, respectively;
- applying insulation plies and at least one metal foil to form a top metal outer ply;
- compressing the first layer sequence in such a way that a liquefaction of the insulation plies occurs and liquid resin fills up gaps between the first recess and the power-electronic metal-ceramic module and gaps between the electronic component and the frame of the metal-ceramic module and subsequently curing the insulation plies;
- and
- producing through contacts and connecting the electronic component with the top metal outer ply.
Circuit board module, comprising:
- a circuit board base frame made of metal-laminated circuit board carrier material, the circuit board base frame including a first recess;
- a power-electronic metal-ceramic module disposed in the first recess;
- the power-electronic metal-ceramic module comprising a ceramic carrier having a metal top ply and a metal bottom ply, and a frame including a second recess accommodating an electronic component, wherein the frame is formed in the metal top ply or the metal bottom ply, or wherein the frame is formed in a metal layer applied to the metal top ply or the metal bottom ply, respectively;
- insulation layers to embed the power-electronic metal-ceramic module in the first recess of the circuit board base frame;
- a top metal outer ply;
- and
- through contacts to connect the electronic component with top metal outer ply.
