    Factory of Fiberglass Insulation Sheet Fr4 Price - Fr4 Sheet ...
    FR4 insulation sheet prices vary significantly by size, thickness, quantity, and supplier, ranging from a few dollars for small pieces (e.g., $1-$4.50/lb or per piece from Alibaba for small batches) to over $100-$600+ for large, thick sheets (like a 4ftx8ft x 1/4" sheet costing $600+) from U.S. distributors like Curbell Plastics or ePlastics, with bulk discounts available. Expect prices from a few dollars for small, thin sheets on Amazon or eBay to hundreds for industrial-sized stock. 
    Price Factors: 
    • Thickness: Thicker sheets cost more (e.g., 3mm vs. 10mm).
    • Size: Larger dimensions (4'x8' sheets) are more expensive than smaller cut pieces.
    • Quantity: Buying in bulk (e.g., 10+ pieces) dramatically lowers the per-unit cost.
    • Supplier: Alibaba/China suppliers often have lower prices for larger volumes; U.S. distributors (ePlastics, Curbell) offer custom cuts but at a premium.
    • Copper Clad vs. Bare: Copper-clad FR4 (used for PCBs) has different pricing than standard insulation grade. 
    Price Examples: 
    • Small Pieces (Alibaba/Amazon): $1 - $10+ (depending on size/thickness).
    • Bulk (Alibaba): $1.90 - $9.80 per kg/unit range for wholesale.
    • Industrial Sizes (Curbell/ePlastics): A 1/4" x 48" x 96" sheet can be around $600+. 
    Where to Buy: 
    • Alibaba, IndiaMART: For wholesale, international, and bulk orders.
    • ePlastics, Curbell Plastics, Professional Plastics: For specific sizes, cut-to-size, and U.S. fulfillment.
    • Amazon, eBay: For smaller, individual sheets for hobbyists.

    How thick is a FR4 sheet?

    AI Overview
    FR4 Material for PCB Fabrication | Sierra Circuits
    FR4 thickness varies, but the most common standard is 1.6 mm (0.062"), with typical options ranging from thin (around 0.8mm) for flexibility/space-saving to thicker (2.0-3.0mm+) for durability, impedance control, or mechanical strength in automotive/industrial uses, with even thinner (<0.4mm) for wearables and thicker (<0.2mm to >6mm) for specialized high-frequency or power applications.
     
    Common Thicknesses & Uses
    • Standard: 1.6 mm (0.062") for general purpose PCBs. 
    • Thin (0.2mm - 0.8mm): Wearables, mobile devices, space-constrained designs, needing flexibility. 
    • Thick (2.0mm - 3.0mm+): Industrial, automotive, aerospace, or large panels needing rigidity and better heat/stress resistance. 
    Key Factors Influencing Choice
    • Space & Weight: Thinner boards save space and weight. 
    • Impedance Control: Tighter dielectric thickness (often thinner) is crucial for high-speed signals. 
    • Mechanical Strength: Thicker boards resist flexing and vibration better. 
    • Component Compatibility: Through-hole components need adequate thickness for soldering. 
    How it's Measured
    Thickness is usually specified for the laminate itself (the core) and also includes the copper layers, which are often 1 oz/ft² (about 35µm) for standard use, but can vary.
