EPTE Newsletter: Internepcon Japan 2020

Reading time ( words)

The largest electronics exhibition in Asia opened January 15 at Tokyo Big Sight. The three-day event was larger than last year with more trade show participants as well as visitors. However, the trade show was not on the main floor this year. Tokyo Big Sight is now home to media that is covering the 2020 Summer Olympics, and hundreds of exhibitions and conventions will have to cancel or change venues.

Internepcon Japan 2020 was somewhat displaced, and the show was divided among the different halls at Tokyo Big Sight. This was an inconvenience for visitors, and it was nearly impossible to visit all booths during the event. I decided to focus my attention on a few select companies due to logistics and a time constraint. The most popular trade show booths were affiliated with car electronics, ultra-high density, wearable devices, and 5G ultra-wideband.

Fine pattern generation is an ongoing project for printed circuit manufacturers. Chemical suppliers JCU and Okuno demonstrated line pitches less than 5 microns produced through a semi-additive process. These processes can generate one-micron traces, but circuit manufacturers are not ready to use the ultra-fine circuits. Current assembling processes and connection technologies that use soldering and wire bonding are not capable of using ultra-fine traces. Compass, a tape shape flex circuit manufacturer in Hong Kong, displayed finer traces than 15 microns designed for driver modules for display devices and double-sided chip-on-film (COF) with microvia holes produced reel-to-reel manufacturing process.

Low-loss materials for high-frequency circuits are an ongoing design project. American laminate suppliers Rogers and Nelco dominate the market for rigid circuit boards. Liquid crystal polymer (LCP) film is leading the flex circuit industry. New low-loss materials—such as low-loss polyimide film, fluoropolymer resins, and PEEK resin—are looking for second positions. One problem is the high cost. 


P-ban.com, an online printed circuit supplier, displayed various products, including multi-layer rigid boards, flexible circuits, and rigid-flex. One of their main features is a series of flexible thick-film circuits produced by a screen-printing process, with fine line circuits down to 30-micron line/space. The company also displayed monocoque circuits, a unique hybrid 3D circuit produced by thick film technology.                

Chinese circuit manufacturers and distributors continue to increase their presence at these trade shows. Most of them claimed they are capable of supplying a broad range of circuit products, including rigid, flex, and rigid-flex. They provided snapshots of their manufacturing plants in China. I was impressed with their buildings and manufacturing equipment; most of their facilities looked better than circuit manufacturers in the U.S. and Japan.

The Chinese manufacturers also displayed typical examples of the circuits. The quality levels of the samples were not on par with Taiwanese and Korean manufacturers. It may take a few more years for them to catch up and have an equivalent quality level.
