Following the adoption of the PumpPrint process from DEK printing machines and the installation of DEK Infinity printers, Tianjin-based OEM HEG has made significant improvements to its adhesive application process yields.

 

The company uses the machines to apply SMT adhesives for their automotive and consumer electronics products, replacing their SMT dispensers.

 

Since the installation of the printers, overall production defect rates have dropped to 20-30 ppm, as confirmed by HEG's quality assurance measures, which include 2-D inspection, visual inspection, AOI and electrical test. The company also reports that throughput for boards that require adhesive application has increased to more than 135 PCBs/hr, and over 81,000 adhesive dots/hr.

 

According to HEG, a major advantage of the PumpPrint process is its ability to operate even in harsh environmental conditions, as the process can adapt to quite a range of temperature and humidity conditions and glue viscosity levels.

 

HEG currently operates 21 automatic insertion machines, seven fully automatic SMT lines and nine manual assembly lines, reportedly achieving 8.16 million SMD placements/day and 8.68 million insertions/day.
