Regarding the color variations for the soldermask, clear, black and white are available as custom silk-screen printed options as well as the standard green color by UV inkjet.
|soldermask’s color||Standard/Custom order||Substrate||Printing method||Gold plating compatibility||Soldermask thickness(TYP)||Alignment precision(between the soldermask opening and the copper pattern)||Alignment precision(between soldermask openings)|
|Green||Standard||PET / PI||UV inkjet||Compatible||20μm||0.2mm||0.2mm|
|Green(waterproof)||Custom order||PET||UV inkjet||Compatible||50μm||0.2mm||0.2mm|
|Clear||Custom order||PET||Silk-screen printed||Subject to negotiation||20μm||0.5mm *1||0.2mm *2|
|White・Black||Custom order||PET||Silk-screen printed||Subject to negotiation||20μm||0.5mm *1||0.2mm *2|
*2 : Requires verification for each individual unit
Please note the following regarding these custom color options (clear, black, white):
-The base substrate must be PET
-Accuracy and conditions are different from the specifications since the printing method is not UV inkjet.
Please contact us for details. contact: https://www.elephantech.co.jp/contact/ -With the custom silk-screen printing, certain gold plating patterns may be unavailable in some cases. Please contact us for details.
*The legend color of P-Flex™ will be replaced from black to white in May 2019 (both PET substrate and polyimide base materials).

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.
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.

Transparent, black and white soldermask coatings by silkscreen printing for PET substrate are also under development and may be available upon request.
|Legend printing||UV inkjet printing (white)|
|Surface finish||Oxidation prevention treatment, Electroless nickel gold plating (option)|
|Outline cutting / Hole drilling||Laser cutting|
|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|
