Product Description

Sheets FW FR4
Epoxy Glass Laminated Sheet

Ref:IEC60893-2-EP-GC202.UNE-53189 Part1./Hgw-2372. DIN-7735(9/75.)/FR4./NEMA LI-1 /JIS KEL-GEF
 

1. COMPOSITION AND PRESENTATION

FW FR4 is a stratified insulator made from fibre glass fabric and epoxy resin.
At delivery time the presentation of the sheets is as follows:
 

- Available sizes: 1020X1220/1020X2040mm	- Thickness: From 0.2 mm
- Colour: Light green / Natural/Black/other any color	- Surfaces: Shining
- On demand we can deliver strips or finished components.

 

1. PROPERTIES.

 

- Very low hygrometric susceptibility	- Small losses at high frequency
- Excellent mechanical properties when cold	- Good dielectric properties
- High resistance to flame ( V-0 )	- Workable while cold up to 3mm. thick

 

1. APPLICATIONS.

Very convenient for equipment for high frequencies and in general for all elements put under high dynamic stresses with high resistance to fatigue, can also be used extensively for test instrucments of PCB, and sports equipment.
