High-Tg PCBs are ideal to use in high-temperature requirements (>170 degree Celsius). Tg or Glass Transition Temperature defines the temperature limit for the proper working of PCB. To put it simply, the working temperature of the PCB should always be less than the Tg(glass transition temperature) value of the substrate. Tg affects the molecular weight, crosslinks, and flexibility of the polymer u...

In electronic devices that send and receive signals like mobile uses High-frequency PCB, this PCB can be used for transmission of radio waves, microwaves. The operating frequency for this board is from five hundred Mega-Hertz to two Gigahertz. To get a high value of frequency from this board such materials are used that fulfill the characteristic for a high-frequency generation. So the strength of...

A Flex PCB or FPCB is a patterned arrangement of printed circuitry and components that utilizes flexible based material with or without flexible coverlay. These flexible electronic assemblies may be fabricated using the same components used for rigid printed circuit boards, but allowing the board to conform to a desired shape (flex) during its application. FPCBs are used widely in everyday technol...

Rigid Flex PCB Fabrication Applications Rigid flex printed circuit boards are boards using a combination of flexible and rigid board technologies in an application. Most rigid flex boards consist of multiple layers of flexible circuit substrates attached to one or more rigid boards externally and/or internally, depending upon the design of the application. The flexible substrates are designed to b...
