Laser Cutting Alumina Ceramic Substrate

The high precision laser cutting processing installations can be used for scribing, cutting and drilling ceramic substrates (Minimum hole diameter:0.2mm).Laser cutting method allows to produce ceramic substrates with
various outside contour geometries, hole patterns, cut-outs and snap-lines.

Benefits:
●High cutting accuracy, very small tolerance.
●Eliminating the time-consuming and costly tool fabrication stage.
●As well as increasing the goods supply efficiency by a big margin and shortening the processing circle.

CRITERIA OF SUBSTRATES BY LASER PROCESS

Laser Cutting Alumina Ceramic Substrate

Ceramic substrate refers to a special process board in which copper foil is directly bonded to the surface of alumina (Al2O3) or aluminum nitride (AlN) ceramic substrate (single or double) at high temperature. The made of ultra-thin composite substrate with excellent electrical insulation properties, high thermal conductivity, excellent solderability and high adhesion strength, and the same as the PCB can be etched a variety of graphics, with a large current carrying ability. Therefore, the ceramic substrate has become the basis of high-power power electronic circuit structure technology and interconnect technology.

Application:

1. High Power Power Semiconductor Modules; Semiconductor Coolers, Electronic Heaters; Power Control Circuits, Power Hybrid Circuits.

2. Smart Power Components; High Frequency Switching Power Supply, Solid State Relays.

3. Automotive, Aerospace and Military Electronics Components.

4.Solar panel components; telecommunications switches, receiving systems; lasers and other industrial electronics.
