Category DescriptionFR4is a glass fiber epoxy laminate,Website:http://www.xce-pcb.com,is the Main material forPCB manufacture.FR4glass fiber epoxy laminate surface colors: yellow FR-4, white FR-4, black FR-4,blueFR-4 and so on.
We are the China's largest exporter of pcb board, we have various types of fr4 materials can be meet the different requirement of customers, and the PCB with ROHS standards, quality assurance of Fr4 materials etc., meantime to provide the most affordable price, also offer one-stop service, to protect the interests of customers.FR4- Glass laminates are widely used for subtractive Printed Circuit Board fabrication because of their ability to meet a wide variety of processing conditions. Thermally stable copper-clad epoxy-glass laminates offer high mechanical strength and machinability and outstanding electrical characteristics. Designed for single and double-sided boards, they provide a combination of processing flexibility and finished board performance needed for many SMT applications.FR4 copper clad is short for fiberglass epoxy resin copper clad, it's divided into the following levels:FR-4 A1 level CCL: This level of CCL is mainly used in military, communications, computers, digital circuits, industrial instrumentation, automotive circuits and other electronic products.This level of CCL widely used, the technical performance indicators to meet the needs of all the electronic products.This level of product quality and fully meet world-class level, the highest level, the best performance of the product.FR-4 A2 level CCL: This level of CCL is mainly used ordinary computer, instrumentation, advanced home appliances and electronic products in general. This grade series CCL widely used, the performance index can meet the general needs of industrial electronic products. A very good price-performance ratio, enabling customers to effectively improve their competitiveness.FR-4 A3 level CCL: This level CCL is mainly used household appliances, computer peripheral products and general electronic products (such as toys, calculators, games, etc.) development and production of FR-4 product. It is characterized by its performance to meet the requirements of the premise, highly competitive prices.Description LayerDouble SidedMaterialFR4Board Thinckness1.6MMSize12*9CMSolder MaskGreenSilkscreenWhiteFinish Copper Thinckness70μm/70μmSurface FinishImmersion Gold 3μ''Board Thinckness Tolerance±10%Impedance Control±10%Warp & Wist0.70%Testing100% Electric Test, IPC Class II.Standard FR-4 Material Properties Performance characteristics Glass Transition Temperature(Tg)150Tg or 170TgDecomposition Temperature(Td)> 325℃Coefficient of Thermal Expansion(CTE)3.0%-3.8%Dielectric Constant(@1 GHz)4.25-4.55Dielectric Constant(@55 GHz)≤5.5Dissipation Factor(@ 1 GHz)0.016Water imbibition (D - 24/23, the thickness of 1.6 mm)≤19mgLaminate thickness0.005”~ 0.125”CombustibilityFV0Density1.70-1.90g/cm³Vertical Layer To The Bending Strength ANormal :E-1/150,150±5℃≥340MpaParallel To The Floor To The Impact Strength (beam)≥233KJ/mExecution StandardGB/T1303.1-1998After Flooding Insulation ResistanceD-24/23):≥5.0×108ΩVertical layer to the electric strength (in the middle of 90 + 2 ℃for transformer oil, thickness 1 mm)≥14.2MV/mPhotos Description: Material FR4 Layers 2 L Size 18*16cm Color Green Board Thinckness 1.6mm Copper Thinckness 1 Oz Dielectric 4.2 Surface Finish Immersion GoldProducts made of epoxy glass fiber board FR - 4, FR - 1, CEM 1, CEM, thick copper foil printed circuit board, high TG PCB, heat dissipation aluminum circuit boards, ultra-small ultra-thin PCB, COB dependend PCB, ceramic plate, high-frequency boards, etc.Surface treatment: hot air leveling (HAL), the full plate electroplating nickel, gold, gold finger, unleaded tin (HASL), chemical gold/silver/tin, prevent oxidation treatment (OSP) and so on.
