Product Description

Electronic 94V0 Pcb Board FR4 Multilayer Circuit Board


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.

Classification of FR4 Printed Circuit Board
According to number of copper trace layers, FR4 printed circuit board is normally divided into following types:
  • Single Sided ,or Single layer;
  • Double Sided or double layer, 2Layers, 2L;
  • Four Layers (4L), Six Layers (6L), Eight Layers (8L), Ten Layers (10L)
  • Board with more than 10L

In fact, for board more than four layers, people will named it "Multi-layer PCB". According to that standard, there're only three types of PCB: Single, Double and Multi-layers.

A print circuit board with FR4 is called the FR4 PCB board. It is a printed circuit board that essentially uses the FR4 sheets.
At first, the FR4 is used in the insulating layer of the circuit board. Then, we add a copper layer on either side of the FR4 sheet.
As a result of this, it becomes CCL (Copper Clad Laminate). Due to FR4, CCL acts as an insulating material.
It is then used in manufacturing FDR PCB boards.

The FR4 gives PCB boards a strength. Moreover, they are great at absorbing moisture and resisting fire.
