Founded in 1984, Weltronics has 130 employees in Hong Kong, Macau and its offices in Shenzhen, Guangzhou, Shanghai, Chengdu, Xiamen and Beijing on the Chinese mainland. "We posted a turnover of US$35.7m in 2004," semiconductor division sales manager Davy Ho notes.
This success is founded on a customer base consisting of 400 active accounts, covering "virtually everything" in the electronics field, he adds. "Our clients make televisions, microwave ovens, air-conditioners, refrigerators, phones, VCRs and many other things," Ho explains.
These manufacturers rely on the 10 million small signal transistors and diodes and rectifiers that Weltronics produces every month for buyers worldwide. "We sell our products under the AUK and YS brand names in the US, Europe and the mainland," he reveals.
Ho says another factor in Weltronics' success is two warehouses in Hong Kong and Shenzhen that cover 3,000 square metres and are capable of handling orders of any size, though the company's minimum order is 3,000 units per reel delivered 4-6 weeks after order confirmation.
"We are well aware of the intense competition in this market and believe we have always responded in an innovative way," he says. "We now supply high-quality products to Japan, the US, Germany, Korea, the mainland and other places."
It is important, Ho believes, to have a good relationship with customers and partners and maintains Weltronics excels in this area. "We strive to meet the production timetables of our customers and ensure that they have a steady and reliable stream of the parts they need to stay ahead of their competition."
A newer company in the LED business is four-year-old OptoSupply Int'l Ltd, which operates a 5,000-square-metre, 200-worker factory in Longgang on the southern Chinese mainland.
The ISO 9001-certified plant specialises in LEDs, including high-power, SMDs and through-hole versions, says marketing manager Victor Cheung. "We make a full range of LEDs, including UV, white, IR and more," he explains, adding that Optosupply does both OEM and ODM work.
Cheung notes that Optosupply's in-house production lines are fully automated, and feature wire and die bonding machines, auto encapsulation, auto bin classification and tape and reel packaging imported from overseas. "We undertake all the production processes in Class 10K clean rooms with temperature, humidity and ESD control," he adds.
Optosupply produces 60 million units a month for markets worldwide, many of which bear its own Optosupply brand name. "We do not have a minimum order requirement and we will ship an order within seven days of confirmation," Cheung adds.
Much of Optosupply's success is due to its dedicated R&D team that creates new value for the company's customers. "Our R&D team focuses on three directions, namely materials, process and optics innovation," Cheung explains.
He says the company strives to improve LED performance by deploying non-imaging optics techniques, including ray tracing and LED light source optical modelling. "We also deploy the Japanese concept of 'gemba kaizen' or workplace improvement, as well as the Six Sigma methodology for eliminating defects," Cheung adds.
Another company committed to quality is Wing Shing Computer Components Co (HK) Ltd, which produces more than 20,000 different products including LCDs and LEDs.
"We have more than 20 years' experience and our consistent efforts have paid off," managing director Lin Kwok Hung claims. "We are known throughout the world and now have more than 60 global partners."
These include many high-profile companies. "We work with Motorola, Intel, Philips, Siemens, Texas Instruments, Toshiba, Hitachi and NEC, among others," he claims, adding, "We stock more than 20,000 items and our WS brand is well-respected everywhere."
All Wing Shing devices such as diodes, thyristors and transistors have been converted to a lead-free finish, which helps boost the company's sales in environmentally conscious markets. "We have a minimum order quantity of 10,000 units, which we deliver 1-2 weeks after confirmation of the order," Lin adds.
Proof positive that no one can beat Hong Kong when it comes to producing and delivering the high quality, competitively priced diodes and transistors that drive the world's electronic devices.
