Part of the rigid circuit board shall consider the bending strength of the vertical layer of the substrate material, impact strength of the parallel layer, water absorption,
Material density, combustibility, melting point of pressure plate, high chemical resistance, thermoplasticity, resistance to drug, abrasion and dimensional stability;
Part of the rigid circuit board needs to consider the material vertical layer to electrical strength, parallel layer to breakdown voltage, specific frequency point（50HZ\1MHZ\13.56MHZ\915MHZ\2.4GHZ\5GHZ\10GHZ）Relative dielectric constant and loss factor.
Special processes: blind hole, buried hole, micro hole, cross blind hole, any order HDI, same surface multiple surface processes/ink, etc.
|Microelectronics technology||Materials technology：||Special (substrate, thermosetting ink, photosensitive ink, silver oil, carbon oil, copper paste, stable performance of the coating adhesive) material;|
Part of the multi-layer rigid circuit board inner layer needs to be embedded with special materials or special devices;

Multilayer rigid circuit boards mostly act as component/circuit connection support carrier in electronic circuit hardware technology environment;
A few multilayer rigid circuit boards can be used as LCR devices (such as variable carbon-oil bridge resistors, parallel plate capacitors, coil inductors, etc.);
Some multilayer rigid circuit boards use differential circuit to design MESH safety circuit.
Some multilayer rigid circuit boards simulate anti-static ESD, anti-interference EMI, resonance, transformer, high-frequency signal transmission circuit.
