FAQ

Can Elephantech supply the product on rigid or rigid flexible printed boards?
Elephantech does not offer the product on rigid or rigid flexible printed boards. The only version of the product that is available is the one that uses flexible printed boards.
Are there any durability data available for long-term use, such as anti-ionic migration characteristics, etc.?
Tests were performed to confirm that our products do not suffer from any short circuit caused by ionic migration in 85℃85%RH, using conductor patterns incorporating interdigital electrodes placed at 0.5 mm intervals, to which a voltage of 50V was applied continuously for 1440 hours.
Are there any options available for the color of solder resist?
Our standard resist color is green. However, transparent, black or white is also available as a special manufacturing specification.
Are there any data available as to the bendability and flexibility of the product?

Reference data for the flex resistance are as shown in the table below. The copper film thickness is 3 μm. However, these values are reference values and not guaranteed values.

The test method conforms to JPCA UB-1 “Flex Resistance Testing Method for Flexible PCB - High speed”, with the pattern width of the test sample at 0.5 mm and the bending speed set at 10 bends per second.

Reference data of flex resistance
substrateBending radius R[mm]Number of bends for which operability has been tested
PI512 million times
PET520 million times
Is there any method that can be adopted to further improve the flex resistance characteristic?
Certain designing specifications such as bending flexible PCBs with the circuit patterns facing inward or running the circuit patterns in serpentine lines in the areas that will be bent up will help improve the products to become more flex resistant. Please consult us for further information.
Do you have any data on its resistence to bends and folds?

See the table below for the reference data of the minimum bending radius when folding the flex PCB with metal molds and such. The values in the table are reference values (not guaranteed values).

Reference data of the minimum bending radius


Reference data of the minimum bending radius
The minimum bending radius R[mm]0.5
Can Elephantech provide the product with double-side printing or via holes?
Elephantech does not currently offer either of these options but is planning on offering them in the future.
Is it possible to perform soldering on the product?

Soldering can be performed on the product.

While P-Flex PI can be soldered with standard solders, P-Flex PET should be soldered with low-temperature solder at around 200°C. Our business partner’s factory is capable of performing low-temperature reflow soldering, so please consult us for further details. If a customer prefers to manually perform soldering instead, Elephantech recommends using lead-free, low-temperature, and flux-cored ECO SOLDER LEO manufactured by Senju Metal Industry.

Is there any particular type of connector that is recommended by Elephantech?

Any connector can be applied as long as the minimum conductor track width of the pads being used is 200 µm, with the minimum spacing between conductive tracks being 200 µm. So most connectors that have a pitch of at least 0.4 mm can be used.

In addition, if connectors with a thickness of 300 µm must be used, our stiffeners can be applied to achieve evenness in thickness.

Do you limit the maximum voltage or current?
There are no limits for voltage. Please refer to the specifications for the limit of the current.
Although you have set the minimum pattern as 200μm, is it possible to make it narrower?
We can try to make prototypes depending on the yield. An additional fee will be charged.
We have only the old format of the Gerber data such as RS-272D. Would you accept it?
We principally accept only RS-272X since it is difficult to guarantee the quality with the other gerber formats. We can make an exception and produce the product but only under your understanding that some problems may occur and that we cannot guarantee its quality.
Do you have a minimum order quantity?
We can manufacture from 1 piece as the prototype before mass production.
We can produce from a single piece.
The material is cresol novolac type epoxy resin. The name of the manufacturer is nondisclosed.
