Fr4 Circuit Board Material Properties

fr4 circuit board material properties

Fr4 is the backbone material upon which most rigid circuit boards are built. however, many are unaware of what fr4 is, let alone why it is the most popular pcb base. read on to learn more about fr4 printed circuit boards, such as what they are, why they are so popular and how fr4 pcb specifications compare to other options within the industry.. About fr4 pcb trace. it’s a misconception to think that fr4 denotes a specific type of material used in pcb manufacturing. instead, fr4 is a standard defined by the nema li 1-1998 specification and covers a set of properties that the material used needs to comply with.. Different materials are used for manufacturing printed circuit boards (pcbs). the type of the material varies, based on the application for which the pcbs are to be used. each material has its own properties, beneficial features, pros, cons, and capabilities, which determine their compatibility with the applications. among the many materials that are used today,read more.

Specifying pcb laminates to your performance needs

fr4 circuit board material properties Most printed circuit boards are manufactured using glass-reinforced epoxy laminate as the substrate. while there are a wide variety of laminates available on the market, fr-4 is both versatile and well-accepted as a standard material for pcb manufacture.. Pcb design-aid: details on the selection of the right printed circuit board material. whereas for many standard applications the classical fr4 material is sufficient, possibly in high tg version (for improved thermo-mechanical properties), for other areas (such as high frequencies) alternate materials are absolutely required..
