Alumina Ceramic Blocks consist of pure copper bonded to a ceramic substrate such as Al2O3 (Alumina), AlN (Aluminum Nitride), HPS (ZrO2 doped) or silicon based Si3N4 (Silicon Nitride).
Mingrui provides two technologies to attach the substrate with the copper. DBC (direct bond copper) – a high temperature melting and diffusion process where the pure copper is bonded onto the ceramic and AMB (active metal brazing) – a high temperature process where the pure copper is brazed onto the ceramic substrate.
The high heat conductivity as well as the high heat capacity and thermal spreading of the thick copper cladding makes curamik substrates indispensable to power electronics. The mechanical stress on silicon chips mounted directly on the substrate (Chip on Board) is very low, since the coefficient of thermal expansion (CTE) of the ceramic substrate is better matched to the CTE of silicon compared to substrates using a metal or a plastic basis
Alumina Ceramic Blocks are produced in a master card format of 5“x7“ and 5,5“x7,5“. The individual parts can be left in the master card format to support more efficient assembly and mounting of components before being separated into individual pieces. We also offer single pieces for single piece assembly.

Mingrui offers you a wide range of production facilities like extrusion, injection moulding, pressing and casting. Depending on product geometry and quantities, we will choose the suitable technique for your products.For the final finishing of the parts we use CNC machining centres, equipped with diamond tools in order to meet high accuracies.
Our aim is to offer the ideal solution for any application. Our engineers therefore offer custom solutions that range beyond our existing product portfolio. With our well-equipped industrial development facilities, we produce innovations that can be rapidly commercially exploited.
