Panasonic FELIOS Adhesiveless Flexible Laminates are the ideal choice for technically advanced Multilayer, Rigid-flex, Double and Single sided applications. FELIOS Flex is an engineered, all Polyimide Substrate with premium copper foil bonded on two sides.

The peelable soldermask SD 2955 is a particularlary heat resisitant 1-pack screen-printable ink that can be easily peelaed off like a film before or after soldering leaving no residues.

RO4000 dielectric materials have long been used in combination with FR4 cores and prepreg as a means to achieve a performance upgrade of standard FR4 multilayer designs. RO4003Cand RO4350Bglass reinforced hydrocarbon/ceramic laminates have been used in layers where operating frequency, dielectric constant, or high-speed signal requirements dictate the need for high performance materials.
