Gallery View: PCB assemblies from EMS providers

EMS companies offer various service packages and have facilities equipped with SMT and DIP lines.

A typical EMS process entails software and hardware development, structural design, molding and sample testing, materials sourcing, production and packing. It extends to storage, logistics and aftersales service. In mainland China, some companies also cooperate with customers in product design.

Shenzhen Kingford Technology Co. Ltd has 22 production lines, including more than 12 for SMT and 60 equipment. Its capacity is 3.5 million points for SMT and 300,000 points for DIP daily. The maker's roster of clients includes Molex, Bosch, Flextronics, GE, Tyco, Panasonic, Hitachi, Cisco, Intel, Philips, Cree and Schneider.

With five production lines and capability for SMT and DIP, Shenzhen Jiubaba Electronics Co. Ltd can accommodate full and partial assembly turnkey orders. Its facility has Panasonic and Yamaha equipment.

Shenzhen Leadsin Technology Co. Ltd has advanced high-speed SMT lines that can handle 0201 chip placement, and DIP lines. Auter and Eltra GmbH are among its clients.

Taiwan-based Effy Deal Global Co. Ltd manages a network of electronic component sources and production lines for PCB manufacturing, PCB assemblies, metal and plastic parts fabrication and cable assemblies. Its services includes logistical arrangements.

Mainland manufacturers turn to local providers of PCBs, passive components, chips, other electronic inputs and materials to lower cost, and use imported variants only when required. In past months, outlay rose by over 20 percent and resulted in higher quotes, although some suppliers opted to keep rates flat for competitive advantage.

In coming months, the majority of companies are not ruling out further adjustments if material and component costs continue to climb.

The PCB assemblies in this gallery have been handpicked by our market analyst for representing current trends in EMS.
