Located in the Tianjin Free Trade Zone, HEG OEM Electronics (Tianjin, China) operates 21 automatic insertion machines, seven fully automatic surface mount technology lines and nine manual assembly lines. With this level of investment, the company is able to execute 8.16 million surface mount device placements and 8.68 million insertions each day. The company also operates in-line and functional test equipment to help ensure the quality of its end product.

In past years, the company used dispensing machines to apply adhesives to its printed circuit boards (PCBs), but found that slow application speeds were affecting board throughput. The process also resulted in an unacceptably high defect rate.
