Standard, customized units make up line

Hong Kong suppliers offer a range of PCB connectors, which include board-to-board, wire-to-board, card-to-board, component to- board, flat flex cable-to-board and jumpers. The products come in standard models, but many companies have inhouse design and tool making capability for customization.

The majority of makers specialize in certain types. Some concentrate on SMD stereo and DC power sockets, while a few dedicate themselves to smart card and USB units. Others have been offering FFC/FPC variants for more than two decades. Many also provide related components such as wire harnesses and cable assemblies.

Dragon City Industries Ltd’s selection includes phone, RCA and DC power jacks. The company has SCART and DIN sockets, speaker terminals, and TV, XLR/microphone, USB and HDMI connectors. Its factories are in Yueqing, Zhejiang province in mainland China.

Ricco Electronics Co. Ltd’s lineup covers assorted connectors such as RGB, and phone, stereo and mini coaxial jacks. It also offers DIN sockets and RCA terminals. The supplier accepts any order size and has a two-week delivery lead time. It conducts production in Dongguan in the mainland’s Guangdong province.

To ensure conformity to global standards, makers upgrade their manufacturing and testing equipment. Many invest in advanced life testers, inductively coupled plasma optical emission spectrometers for elemental analysis, profile projectors, and electric discharge, wire-cutting, grinding and CNC machines. They source high-grade raw materials from Japan, Taiwan and the US.

Companies can modify existing units based on customers’ requirements, and accept orders for small lots.

The bulk of output, including RCA, phone and power jacks, and terminal blocks, is shipped to makers of consumer A/V devices and home appliances. Others go to the telecom, automotive, computer, medical and industrial sectors. Hong Kong suppliers also cater to wholesalers and distributors, mainly for standard models.
