Product Description

This FR-4 double-sided PCB with immersion gold surface finish,only 0.8mm thickness,comes with certificates of UL, ISO, TS16949.

We are a professional factory with 16 years experience in manufacturing printed circuit boards, which can be made by a various of materials such as Aluminum/FR4/Cermic/Rogers/High Frenquency/FR1/FR2/FR4/CEM1/CEM3.

Your are welcome to check this FR4 PCB board with good quality and cheap prices.

Note: FR-4 is the primary insulating backbone upon which the vast majority of rigid printed circuit boards (PCBs) are produced. A thin layer of copper foil is laminated to one, or both sides of an FR-4 glass epoxy panel. These are commonly referred to as “copperclad laminates.”

FR-4 copper-clad sheets are fabricated with circuitry etched into copper layers to produce printed circuit boards. More sophisticated and complex FR-4 printed circuit boards are produced in multiple layers, also known as “multilayer circuitry”.
