About Elephantech's manufacturing method (Pure Additive™️ method)

P-Flex® – Print Metal Ink Directly and then Apply Copper Plating

The Pure Additive™️ method involves converting metal into nanoparticle ink state, which is then printed on a substrate using an inkjet printer. The metal is then grown by electroless copper plating to form a circuit. This technology requires fewer manufacturing processes compared to conventional methods, resulting in significant reductions in environmental impact and improved cost performance.
(* Patent No. 6300213)

The world's first practical application using printing technology

Taking the example of printed circuit boards, the conventional manufacturing method was an extremely long process in which copper foil is manufactured, laminated with film (production of CCL), and laminated with photosensitive materials before the desired copper pattern is achieved by dissolving and discarding the copper foil from unnecessary parts by exposure, development, and etching.

Our process achieves the desired copper pattern by printing the metal onto film and growing it, not only forgoing the need for copper foil manufacturing and CCL manufacturing processes but also eliminating the need for the etching process to dissolve and discard the copper foil.

Environmentally Friendly, Proprietary Technologies
LCA_230607_en_16_9Led by the growing momentum to reduce greenhouse gas emissions, more significant consideration is given to environmental impact.
Amid such global trends, Elephantech believes it is a corporate responsibility to communicate on efforts made in reducing environmental impact and has worked on the visualization of its sustainability efforts from the three angles of “climate change,” “natural resources,” and “hazardous substances.” 

Our Sustainability

Elephantech: Company Introduction by CEO 2022 (see 0:38-2:40)

Before: 「Etching unnecessary metal」→ Lot of waste.

Now:「Print the metal you need」→ There's no waste.


P-Flex🄬 Mass Production Case Studies

Xacti-logo-21_Dec   Xacti Corporation

P-Flex® was adopted in the camera unit for the following safety camera systems:
・Safety camera system for heavy machinery【DOBORECO® Series】
・Safety camera system for forklift 【FOCRECO】
P-Flex® was adopted because it uses a polyimide base material that has excellent heat resistance and mechanical properties, as well as the flexibility needed for set integration. These properties enable a rapid start to mass production. The customer's interest in the product's low environmental impact also contributed to its selection.

Customer’s Voice: Why P-Flex® ?
We focused on this product as an environmentally friendly flexible substrate manufactured using a process that reduces the amount of waste water, and as a product that realizes sustainability.
In addition to the environmental considerations, we are also grateful for the flexible support we received in our product development process from prototype evaluation to mass production readiness, which played a big role in helping us achieve product delivery on schedule.

P-Flex® is used in the pressure sensor module which plays a pivotal role in the Air Leak Test System.
Air leak test system deploys multiple pressure sensors in high density space and hence such modules need to be small. Typically, initial cost of flexible circuit boards can be a big issue depending on the lot size, and there are many cases where there is no choice but to use cable wiring that takes up a lot of space. Elephantech's P-Flex® was awarded for this system as its manufacturing method substantially reduces costs both of mass production and development regardless lot size while also allowing for the miniaturization of the module.

Customer’s Voice: Why P-Flex® ?
The utilization of P-Flex® resulted in a 30% reduction of the footprint, as well as a decrease in the total number of components required and the streamlining of assembly procedures.
