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?
The only solder resist color that is currently available is green.
Are there any data available as to the bendability and flexibility of the product?
Reference data for the flex resistance is shown in the table below. The values in the table are the reference values (not guaranteed values). The testing method conforms to "Flex Resistance Testing Method for Flexible PWB - High speed(JPCA UB-1)" and the pattern width of the test sample is 0.5mm. While the substrate thickness is 50 µm, there is no adhesive layer in our products. Therefore, the total thickness is close to that of a flex PCB with a thickness of 25µm. In terms of flex resistance, our products might be less flex resistant than a typical flex PCB.

Is there any method that can be adopted to further improve the flex resistance characteristic?
Certain designing specifications such as bending FPCs 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

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. However, please note that it is crucial to use low-temperature solder and perform soldering 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.

How can I purchase the AgIC products?

We are planning to have an official agency for global sales. Meanwhile, these products below are available at the products page on our online shop.

  • Prototype Ink Kit
  • Circuit Paper
  • Circuit PET Film

Those who are interested in other products such as Circuit Marker, Circuit Eraser and Circuit Study Kit can subscribe a newsletter to get informed of the agency. Sign up at the link below.

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.
Is it possible to change the base film material to polyimide or another type of material?
Unfortunately, Elephantech only offers the product that uses heat-resistant PET as the base film material at the moment.
Is it possible to request a base film thickness other than 50 µm?
Our current standard thickness is 50 µm. However, 125 µm is also available as a special manufacturing specification.
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 produce from a single piece.
Could you tell me the name of the solder resist's manufacturer and its raw material?
The material is cresol novolac type epoxy resin. The name of the manufacturer is nondisclosed.
