FPC Cover Film (Coverlay)
Designed to offer best protection for flexible printed circuit boards (FPCs). Made from high-performance polyimide, this coverlay film guarantees long-lasting protection for the sensitive components of the PCB by shielding the conductive layers from environmental damage like moisture, dust, and pollutants.
Without sacrificing its protective properties, this flexible, strong film can resist bending, folding, and extreme temperature swings. It also guarantees, under demanding circumstances, copper foil on the FPC stays free from oxidation and corrosion. Perfect for uses needing great dependability, the FPC Cover Film is ideal for usage in electronics where durability, performance, and adaptability rule most importantly.
