Irresistable Forces


Welleader Co Ltd produces Royal-Ohm brand resistors, including chip, carbon and metal film, metal oxide film, fusible and wire-wound and fixed versions

Hong Kong has a long and successful tradition of manufacturing quality resistors, and companies are well-informed about the latest engineering requirements and demands. While most continue to produce axial-lead resistors, several enterprises have also acquired significant experience in the production of chip resistors.

Founded in 1987, Welleader Co Ltd acts as an agent supplying a broad variety of resistors, including chip, carbon and metal film, metal oxide film, fusible and wire-wound and fixed resistors in a range of physical sizes, value ranges and tolerances.

Among the company's featured products are rectangular chip resistors sporting the Royal-Ohm brand that come in a broad spectrum of values ranging from 0.1 Ohms to 22M Ohms, with a tolerance of plus and minus 1%- 5%.

"Our chip resistors are well-received because we can provide large quantities of reasonable quality goods to the mid- and high-end sectors of the market," says director Lam Chi Biu.

Lam says the company's resistors meet Japanese specification JISC 5202 and are produced under strict Japanese management norms. "Delivery of minimum quantity orders of 5,000 resistors is fast as we can provide goods ex-stock within three days," he adds.

Lam says that Welleader's resistors find their way into toys, adaptors, mobile phones and other electronic equipment. "Business is slightly better for us this year as factories in Guangdong Province are taking in more orders for finished products," he notes.

The principal buyers of Welleader products are Hong Kong-based companies with production facilities on the mainland. "We also have secondary markets in the US and New Zealand," Lam says.

Business is also improving for Asia Akita Electronic Technology Co Ltd, which produces a wide range of resistors including wire-wound, non-inductive and low Ohm models, carbon and metal film types, chip resistors and cement resistors; all usually bearing the TY-OHM brand.

A wide array of wire-wound resistors for customers with higher power rating requirements forms the most popular line, coming as they do in a variety of diameters.

"Thanks to our experience, and the fact that we have factories in Suzhou, Shenzhen and nearby Longgang, we have been very successful in developing the market, particularly for our wire-wound resistors," says general manager Kuo Shing Shyh. "We employ a highly skilled workforce of more than 700 on the mainland, while our facility in Linkou, in Taiwan, employs 100."

The mainland is the most significant market for Asia Akita, while Japan and Korea are also important destinations. Ceramics are sourced on the mainland, as are lead wires, some of which are also sourced in Japan. Coating elements come from Taiwan.

"Our experience spans more than 47 years," says Kuo, "and production quality is demonstrated by ISO 9001- and ISO 14001-certification, while our strict quality control procedures are major plusses for our customers."

With a production capacity in excess of 800 million resistors per month, the company requires minimum orders of 10,000 pieces for delivery one week after confirmation for items in stock or 2-3 weeks after confirmation for production runs.

A different approach is leading to better business for Golden Sing Industrial Co, founded in 1995. "We have enjoyed an increase in our business as we are focusing on the use of 'green' materials, which enables our products to be more widely sold in Europe where environmental regulations are stricter," says marketing manager Maggie Yan.

While producing a variety of resistors, including SMD models, wire-wound and metal oxide resistors, Golden Sing enjoys most success with its carbon film and metal film resistors.

"The popularity of carbon film resistors stems from the fact that they are reliable and can be used in a wide range of products," says Yan. "Ours have a tolerance of plus and minus 5%."

While the company sources most of its materials from the mainland, for those components with RoHS "green" requirements, materials may be procured from Taiwan.

"Apart from that, we believe that our quality control emphasis - with stringent QC procedures in place - and a relatively short lead time for large quantities form our major selling points," Yan says. "Generally, delivery time for large orders is 2-3 weeks as we keep sizeable stocks."

Europe, with its stricter environmental protection standards, is emerging as the most important market for Golden Sing, followed closely by the US, Japan and Korea.

Production takes place at Golden Sing's factory in Shenzhen that employs some 400 workers. Chan says the minimum order requirement and price varies according to the requirements.

With Hong Kong's enviable tradition and record of innovation, it comes as no surprise that resistors from local manufacturers are an irresistible proposition for global electronics manufacturers.
