|Hing Keung Printed Circuits Board Ltd produces double-sided and multilayer PCBs of high precision and density|
They are the staples of the electronics industry, and therefore need to be reliable and trustworthy: which is why Hong Kong manufacturers of PCBs take pride in a wide range of flexible, rigid and multilayer options
A vital element in electronic and communications products, printed circuit boards (PCBs) house and connect many different circuits, components and processes. Employing the latest technology, Hong Kong manufacturers of PCBs can meet all needs, be they for rigid or flexible, single-sided, double-sided or multilayered.
Introlines Industrial (HK) Ltd is a classic example. This company has been manu-facturing a complete range of PCBs since 1996. "Our tight quality control procedures ensure that we reach a 99.7% shipment-accept rate, which is very high," says sales manager Edward Chau. "As a reliable PCB partner, our quality means our customers' products enjoy healthy growth and a good reputation in the market."
Mainly selling under its own ITL brand, the firm has a monthly production capacity for 500,000 square feet of PCBs. The maximum board size is 450x650mm and the minimum board thickness is 0.10mm per layer, with up to 14 layers possible for rigid boards and two for flexible boards.
"The trend is towards smaller PCBs with more complex circuit designs by reducing the size and circuit widths of portable electronic applications," comments Chau, adding that the main product sectors for the company's PCBs are telecoms, security devices and controls, with double and single PCBs accounting for 75% of sales.
The minimum order value is US$1,000, and the boards are manufactured at the company's 250,000-square-foot factory in Guangdong Province on the Chinese mainland. Delivery is 2-3 weeks after order confirmation.
"Approximately 80% of our PCB products comply with the RoHS directive that restricts the use of toxic substances such as lead in electronic and electrical equipment," says Chau. "However, the US still accepts HAL standards, which account for non-RoHS PCBs."
Introlines also has ISO 9000 certifi-cation and is TS 16949-approved. Its main markets are Europe and the US, but it expects Eastern Europe and Canada to be growth markets in 2007.
Meanwhile, Japan, the US and China are the main markets for Leadway Technology Corp Ltd's range of double- and multilayer (up to 10) PCBs, with lead-free and RoHS-compliant options available.
The company was set up in 1999 and its PCBs are mainly used in telecoms, controls, digital TVs and multimedia products. "Our PCBs are very competitively priced and we believe in total customer satisfaction," says general manager Eddy Tsoi.
The firm has a monthly production capacity of 500,000 square feet of PCBs, while the maximum board size is 510x610mm. The manufacturing process takes place at an 11,000-square-metre, ISO 9000-certified plant in Guangdong Province. "We can produce boards to a minimum thickness of 0.3mm, FR-4," Tsoi comments, adding that delivery is 3-4 weeks after confirmation for minimum order values of US$1,000.
Another supplier, Soar Industries Ltd, specialises in lead-free, flexible PCBs, which are used mainly in electronic equipment, mobile phones, and audio and video products.
"There is a trend towards using flexible PCBs, which have many advantages over rigid versions, such as being lightweight, thinner and enjoying reduced assembly costs," explains manager Tony Chan. "We can produce single- and double-sided and multilayered boards of up to four layers."
The minimum thickness available is 0.06mm and the maximum board size is 600x800mm. Delivery takes place 7-10 days after order confirmation from the firm's factory in Jiangsu Province on the mainland that can produce 120,000 square feet of PCBs a month.
The company, which was established eight years ago, has ISO 9001 certifi-cation and its products comply with RoHS and the UL safety standards. "Double-layer PCBs are our best sellers and our main markets are the US, Germany and the UK," says Chan.
On the other hand, Asia is the main market for Hing Keung Printed Circuits Board Ltd, and accounts for 60% of all sales. Europe and the US account for 30%. The firm's range of PCBs includes double-sided and multilayer versions, with up to 12 layers, for use in electronics, communi-cations products and computers.
The company has been manufacturing boards since 1995, and is confident about its long-term future. "Taking proactive steps to continually improve and upgrade our manufacturing operations and production capability is just one way we remain competitive," says director Lam Po Ping.
"Our existing strategy, first implemented some 10 years ago, comprises investing in and building a quality manufacturing presence in China, and this has proved to be the correct way to move ahead," Lam asserts. "The strategy has helped us weather difficulties such as price erosion and, barring unforeseen circumstances, we expect continuing good results in the second half of the current financial year."
The ISO 9001-certified company has a 15,000-square-metre factory in Dongguan that claims a monthly production capacity of 30,000 square feet of PCBs. The maximum board size is 520x622mm and the minimum board thickness is 0.4mm. Delivery after order confirmation is appro-ximately 20 days, and the minimum order value is US$3,000.
While prices for all of these manu-facturers' boards vary depending on many factors, such as number of layers, rigid or flexible, thickness, complexity and finish, it is clear that Hong Kong can and does provide a complete range of products and quality.
Getting onboard with Hong Kong PCB manufacturers could be the best way to drive future business.
