Main Characteristics of P-Flex™ PET

It is inexpensive to mass produce compared to polyimide base materials, and it is suitable for environments with high or extreme humidity due to it being resistive to absorbing moisture. Also, parts other than the pattern or components can have a transparent appearance when transparent resist is used.

About P-Flex™

P-Flex™ is a single-face flex PCB manufactured using the Pure Additive™ method. Conventionally, electronic circuits have been manufactured by applying a method known as lithography, in which a thin metallic sheet is first applied to the board surface, and then unrequired sections are melted away.

Pure-Additive-method

The Pure Additive™ method (*) developed by Elephantech is a concept completely opposite to what had been used until now, using a proprietary manufacturing technology that prints metal nanoparticles with inkjet only on the necessary parts and grows metals by electroless plating technology.
(* Patent No. 6300213)

By reducing the amount of metal, liquid waste and man-hours, we can lessen manufacturing costs and shorten the lead time.
Elephantech will continue to reduce its environmental burden and contribute to the achievement of SDGs.

Stiffeners When specifying the thickness of the connector part, film stiffeners can be used to adapt to connectors of 200 µm or 300 µm in total thickness.
Component mounted parts and such can be adapted by using FR4 stiffeners of 0.1, 0.3, 0.5, 1.0, and 1.6mm in thickness.
Other stiffeners, electromagnetic wave shield film, double-sided tape and such are also available.
Inspection Visual inspection + opens/shorts test
