Microwave with ceramic filling
PCBs with ceramic filler are in many respects worse than other alternatives, and therefore are used much less often. Due to special aspects of use, such as shrinkage and large surface roughness, now they are used only in small devices. For example, for integrated circuit packages, in micro assemblies and so on.
Such PCBs are made of polycarbonate-based polymers, which are filled with ceramic filler and reinforced with fiberglass. This type of materials was created to provide characteristics similar to Teflon cards, while making them compatible with classical processing methods.
Microwave on a ceramic base
The printed circuit board is made of materials that are based on fluorocarbon compounds, and additionally reinforced with fiberglass — Teflon. Such PCBs are chosen because they:
— Have increased reliability;
— Have high electrical strength;
— Can operation at high temperatures;
— Have good moisture resistance;
— Easily survive sudden temperature changes.
The glass transition temperature of the used materials is above 240 degrees Celsius. That’s why such PCBs are ideal for power amplifiers, antennas, communication systems, satellite amplifiers and other areas of radio communication.
The materials are also used where a high digital data transfer rate is required and accuracy and signal speed are primarily important.
Composite ceramic material with organic binder. PCBs made of such laminate combine well the qualities of both fluoroplastic and ceramic boards.
High mechanical and electrical stability makes the composite material a good option for creating multilayer PCBs for use in high temperatures and their differences. For example, in aerospace devices.
Saifon Technologies produces ready-to-operate microwave PCBs according to the customer's ready documentation.
