Mobile Phone, Smart Phone, Automotive, LED Lighting, High Power Application,
Computer, Instrumentation, Communication Equipment, Electronic Game Machine, VCR, etc.
- Core Thickness: 0.002” (0.05mm) to 0.200” (5mm), available in sheet or panel form
- Copper Foil: 1/4oz to 12oz
- Prepregs are available in roll or panel form
- E-Glass styles: 7628, 1506, 1500, 2113, 2313, 3313, 2116, 1080, 1086, 1078, 106 & 1067, etc.
Note: For cores ≤ 0.005”, it is recommended to use the reverse treated copper due to the low profile. The peel strength for RT foil is ≈1-2lbs/in (0.35Kg/m) less than standard foil.
