SY,ITEQ Fr4 material

  • FR means Fire Retardant.
    FR4 material, it is a glass fiber epoxy laminate material. Fr4 is very commonly used PCB material. A 1.20mm FR4 uses 6 layers of type 7628 Fr4 glass fiber material. The Blue UL/manufacturing logo is print in the middle (the third layer).
    the 7628 laminate include two types of logos: red color and blue color, Red is UL94-V0, blue is UL94-HB. If there are Blue print on your laminate, it is either XPC (phenolic) or G10 (glass epoxy) Fr4; these are older Fr4 Laminate materials.
    Solder mask color: green, black, blue, white, yellow, purple, and matt, etc.
    Solder mask hardness: 6H

FR4 rigid PCB Printed Circuit Board

  • FR-4, is a worldwide acceptable international grade desination for fiberglass reinforced epoxy laminated. After add copper layer on one or both side FR4 laminate, it become to Copper Clad Laminate (CCL), and this is the non-conductive core materail for normal PCB board. PCB by using FR4 as core laminate is "FR4 PCB".
    Fr4 rigid PCB is used to rigid support and electrical connect electronic part using conductive trace, signal tracks.in some place of USA, PCB also named PWB if there are no extra electronic components was added on.
    Classification of FR4 PCB
    base on number of copper layers, FR4 PCB is normally divided into following types:
    Single Sided (S/S), or 1 layer;
    Double Sided (D/S), or 2 layer, 2Layers, 2L;
    Four Layers (4L), Six Layers (6L), Eight Layers (8L), Ten Layers (10L)
    Board with more than 10L
    or 3L, 5L,7L, 9L (one layer etched)
    more than four layers, normally we call it "Multi-layer PCB". so, we can say only 3 type: Single, Double and Multilayers Fr4 rigid PCB.
    If base on manufacturing technology, normally based on hole diameter, we can say:
    Normal through hole Fr4 rigid PCB (diameter >=0.20mm (8mil)
    HDI Fr4 rigid PCB (diameter <=0.15mm (6mil)
    base on copper thickness, we can say:
    Normal copper Fr4 rigid PCB : copper thickness: 0.5 OZ, 1.0 OZ, 2.0 OZ,
    Heavy copper Fr4 rigid PCB : copper thickness: >= 3 OZ
    base on core material, we can say:
    Rigid FR4 PCB: Only FR4, it is rigid for whole board;
    Base on Tg value of FR4, it can be divided into
    Normal Tg: TG135, TG140;
    High Tg: TG170, TG180;
    Base on working frequency (RF) level of PCB, it can be divided into
    Normal: < 300 Mhz
    High Radio Frequency: >300MHz, to 3GHz,or even larger number
    base on board thickness,
    Normal thickness: >=0.30mm
    Extra Thin thickness Fr4 rigid PCB: 0.10~0.30mm;
