FR4 is not a material`s name, but a kind of grade of fire-resistant, which represents resin materials can self-extinguish when firing. Now there are all kinds of FR4 materials using as PCB, but the majorities are composite made of epoxy resin, filler and fiberglass.
G10 FR4 sheet mainly used as insulation structure parts in electrical, electronic and other industries.
Key Features :
• Flame resistance
• High dielectric strength
• Moisture resistance
• Heat resistant
• Temperature resistance: 180-200℃
• Under the normal temperature 150 ℃, it still has high mechanical strength.

2. Translator
If translator is required and can't be provided by purchaser then we will provide a translator for same charge as initial installation stipulated above. All communicate with our engineer should be in Chinese. Any translation provide by us will be based between English and Chinese only. Purchaser is responsible for the translation between local language and English.
Commercial Terms
1. Warranty
All parts are under two Year Warranty with defects from manufacturer. Any other defect caused by human error, mishandling, wear-and tear & any foreseeable conditions will not be covered by this warranty. All electronic parts and component can be guaranteed by original part's manufacturer or our company.
Â
2. Payment
30% of the total contract amount is to be T/T into assigned account at the period of 5 working days after the Purchase contract is signed.
70% of the balance must to be made via T/T of the remainder balance amount of the purchase contract before the ordered equipment is to be delivered 10 working days prior of the shipment.
