Etron Technology, Inc. is a fabless IC design and product company founded in February 1991, specializing in buffer memory and system-on-chips.
In the new era of the “experience economy”, Etron's buffer memory products act like brain memory, its USB3.0 host products are like nerves providing connectivity, and the webcam IC are like eyes supplying vision. Moreover, the flash drive – commonly known as a thumb drive – is now moving from the USB2.0 era to USB3.0. Etron's recently launched USB3.0 device controller ICs have established world records in terms of speed.
Etron has completed the development of USB 3.1 Type C and second-generation USB electric power transmission (USB-PD 2.0) chips for products including, the industry’s first electric power transmission USB-PD 2.0 control IC, a Type C connector IC, and the world’s first single-chip that integrates Type C and USB-PD 2.0 functions.
USB 3.1 Type C connectors have just 2.4mm plugs and hot insertability. They are also pluggable on their reverse side and can simultaneously transmit USB, PCIe and display port signals. They transmit 100W of power and can replace wire functions of traditional power sources, such as USB and HDMI. Therefore, they can solve the current difficulties with having separate lines of transmission for power, data, and audio-visual in 3C products.
Etron Chairman and CEO Nicky Lu stated that the outlook for USB3.1 Type C applications is extremely optimistic. Just one connecting outlet can take care of everything. It is therefore anticipated that in the future, it will be comprehensively used in many 3C products.
Nicky Lu also pointed out Apple’s new MacBook model supports a USB 3.1 Type C connector and predicted that it will lead other companies to follow suit. When more companies adopt this, it is antici-pated that connectors will enter the brand new USB 3.1 Type C era.

Wanshih Electronic Co.
With the latest standard USB and LTE, Wanshih is focusing on the top speed of connecting users’ life.
Chasing ultra-high speed, high power and tiny size, USB 3.1 interface is what Wanshih is focusing on right now. The company takes the lead of passing USB-IF USB 3.1 Gen2 10G speed standard as the first cable assembly manufacturer.
Wanshih has devoted to USB 3.1 C to C coaxial cable ultra-high speed technology. Emphasizing on antenna design since 2001, the company has full antenna production lines(LTE/UMTS/GSM/WiFi). Its ultra high precision 3D printer and CTIA 3D full size OTA (Over The Air) LAB support users with antenna total solutions.
With the PC industry starting to adopt USB 3.1 technology, prices for cables that can connect to these products are also expected to rapidly fall, according to manufacturers.
In March, Apple was among the first to come out with a laptop built with a single USB 3.1 port that used the Type-C connector.
The USB 3.1 standard promises data transfer speeds of 10G, two times faster than USB 3.0. But given that the technology is still new, prices for USB 3.1 cables with Type-C connectors are hovering between $24 and $29.
More affordable cables, however, will start to arrive in next year’s first half, said Lake Chang, Gneral Mnager of Wanshih Electronic, a maker of USB connectors. By next year, the prices could fall to $15,” he said.
Lake Chang pointed out that USB 3.1 is essential in completing PC, consumer eletronics and even Internet of Things (IoT).
Lake Chang forecast that USB Type-C is a specification for a reversible-plug connector for USB devices and USB cabling, which will probably make a biggest wave of replacement in the past ten years.
