Product Description

FR4 PCB CEM1 CEM3 Electronic Circuit Board Manufacturer


FR-4, is a widely acceptable international grade desination for fiberglass reinforced epoxy laminated that are flame retardant (self extinguishing). After add copper layer on one or each side FR4, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal printed cricuit board (PCB). Printed circuit board using FR4 as core material will be named as "FR4 PCB".

PCB is used to mechanically support and electrically connect electronic components using conductive pathways, tracks or signal traces etched from copper clad laminate substrate. Sometimes, PCB also named Printed Wiring Board (PWB) or etching wiring board if no extra electronic components was added on.

Features of FR4 to Consider When Choosing FR4 PCB CEM1 CEM3 Electronic Circuit Board

When choosing or ordering FR4 printed circuit board, an electrical engineer or technician must look at the following features:

  • Thickness:

The thickness of an FR4 sheet varies depending on your project. Ideally, you will require an FR4 with a thickness of 1.3 thou to 3 inches.

  • Impedance Matching:

The impedance matching is very important in high-frequency PCBs. It helps to maintain the function of the board of directors. It also determines the capacitance of the layers in multi-layered boards.

  • Space & Flexibility:

Depending on your project, you can choose an FR4 material for your PCB boards. Mostly, people prefer thinner sheets as they take less space and are more flexible.

  • Weight of the FR4:

Since, the thickness of the board determines its weight. For lighter products, choose FR4 boards with lighter

  • Thermal Conductivity:

To determine the temperature management of the FR4, look at the value of the thermal coefficient of dielectric constant. However, FR4 is heat resistant and it is one of the main reasons for its popular use.
