Boards for electrical circuits - Import export

DBC ceramic substrate: Direct bonded copper (DBC) substrates are commonly used in power modules, because of their very good thermal conductivity. They are composed of a ceramic tile (commonly alumina) with a sheet of copper bonded to one or both sides by a high-temperature oxidation process (the copper and substrate are heated to a carefully controlled temperature in an atmosphere of nitrogen containing about 30 ppm of oxygen; under these conditions, a copper-oxygen eutectic forms which bonds successfully both to copper and the oxides used as substrates). The top copper layer can be preformed prior to firing or chemically etched using printed circuit board technology to form an electrical circuit, while the bottom copper layer is usually kept plain. The substrate is attached to a heat spreader by soldering the bottom copper layer to it. 1. Thickness of substrate can be thin: 0.25mm,0.28mm,0.45mm,0.5mm,0.635mm,1.0mm,1.5mm, 1.8mm,2.0mm 2.

Flexible circuit boards, also known as "flexible boards", are printed circuits made of flexible insulating substrates. Flexible circuits provide excellent electrical performance, can meet the design needs of smaller and higher density installations, and also help reduce assembly processes and enhance reliability.

PCB board is also called printed circuit board, it can realize the mutual connection between electronic components. PCB board can be used in different industries of electronic products, it plays an important role. So what are the components of the PCB board? PCB circuit board is composed of: pattern, dielectric, through hole, solder resistant , silk screen and surface Finish.
