Frequently Asked Questions — Glass Epoxy FR4 Parts

Direct answers to the questions buyers ask most. Still unsure? Call +91 94938 66029 or WhatsApp us.

What is the difference between G10, G11, FR4 and FR5 glass epoxy?

G10 is epoxy-glass laminate without flame-retardant (B-class, 130°C). FR4 is G10 + flame-retardant chemistry (UL94 V-0, same 130°C). G11 is high-temperature epoxy-glass (H-class, 180°C) without flame-retardant. FR5 is G11 + flame-retardant (UL94 V-0, 180°C). FR4 is the industry workhorse for PCB stiffeners, bus-bar supports and switchgear; FR5 is used in high-temperature motor insulation, VFD IGBT heatsinks and induction coil formers.

What thicknesses and sheet sizes are available?

Thickness range: 0.5, 0.8, 1.0, 1.2, 1.6, 2.0, 2.4, 3.0, 3.2, 4.0, 5.0, 6.0, 8.0, 10.0, 12.0, 16.0, 20.0, 25.0, 30.0, 40.0, 50.0 mm. Standard sheet sizes: 1000 x 1000 mm, 1000 x 2000 mm, 1200 x 2400 mm. Custom cutting from larger laminates by waterjet or CNC router. Oversize up to 2440 x 1220 mm available on indent.

What dielectric strength and mechanical specs can I expect?

Per IEC-60893 / NEMA LI-1 specifications: Dielectric strength perpendicular 14 kV/mm (FR4), 20 kV/mm (G11/FR5). Flexural strength 450 MPa minimum, tensile 310 MPa, compressive 455 MPa. Water absorption <0.15% (24h). Flammability UL94 V-0 for FR4/FR5. Volume resistivity 10^14 ohm-cm. CTI (Comparative Tracking Index) 175 V for FR4.

Can you CNC-machine threaded holes and tapped standoffs in FR4?

Yes. We tap M2.5, M3, M4, M5, M6, M8, M10, M12 threads directly into FR4 / G10 sheets up to 50 mm thick. For high-cycle applications we press-fit brass or stainless threaded inserts (M3 / M4 / M5 heli-coil-equivalent). Counter-bored holes, through-holes, slots, blind-pocket milling and chamfered edges all supported from DXF / STEP / IGES files.

Do you provide IEC-60893 / UL / BIS certification with FR4 parts?

Yes. Every FR4 batch ships with: (1) Mill-Test Report (MTR) from the laminate supplier showing IEC-60893-3-2 EP-GC-202 / 203 / 308 grade compliance, (2) UL94 V-0 flammability certification, (3) UL recognized component tag E-number where applicable, (4) BIS IS-3043 traceability for Indian switchgear projects, (5) RoHS-3 compliance letter. ISO-9001 QA stamp on inspection report.

Lead time and MOQ for FR4 glass-epoxy machined parts?

Prototype 1-10 pcs: 3-5 working days. Standard 100-500 pcs: 7-10 days. Bulk 1000-5000 pcs: 15-20 days. 10,000+ pcs/month production: 25-30 days first lot, 15-18 days repeat. No MOQ for standard sizes; MOQ 50 pcs on custom DXFs. Express 48-hour slot available for ongoing switchgear and EV customers.
