Schweizer: Materials for PCBs / Schweizer Electronic AG

Background

Important PCB properties are determined by the used base material. The choice of the right base material is therefore based on the technical specification for the overall application in which the PCB will be supplied. And last but not least, the costs arising from the choice of base material play an important role.

Applications

Each sector has specific requirements for the application in question. In the automotive sector, the coarse ambient conditions and high reliability requirement influence the choice of the right base material. In telecommunications, the need for signal integrity and focus on the dielectric properties of the insulation material prevail.

High-frequency PCBs for use at up to 79 GHz have been introduced in the automotive sector through radar-supported applications such as ACC. These extremely special, expensive materials are generally used to produce hybrid circuits. This involves an outer antenna layer made from a high-frequency base material with a core made from a standard material.
