Pemtron Solder Paste Inspection Upgrades EPE Production

Seoul, Korea — Pemtron's TROI 5700 3D solder paste inspection systems (SPI) has been selected to go into service at EPE Corporation, Manchester, New Hampshire — a third-generation, ITAR-Registered, veteran-owned provider of complex electronic contract manufacturing services.

EPE Corporation will utilize the SPI within its quality assurance program, for automated inspection of its printed circuit boards. After assessing the capabilities of four systems, EPE selected the Pemtron SPI over the other offerings. "The features of the system were comparable to the other vendors we evaluated, but offered better value overall," said Matthew Amidon, EPE Corp.'s Director of Manufacturing Operations. "The thing that stands out is the willingness of Pemtron engineering to provide custom solutions to meet our needs."

EPE focuses on manufacturing complex assemblies for low volume, high mix products, providing supply chain optimization for industries requiring high levels of flexibility, configuration management, repair depot services and logistics solutions. The company specializes in contract manufacturing services, providing expertise to support a diverse array of end markets including: defense and homeland security, medical, communications, industrial automation, consumer and RF.

Critical Inspection Needs
EPE's critical inspection requirements called for an SPI solution that would meet the demands of its unique operation. The systems are used in-line to inspect 100 percent of all of its screen printed boards prior to assembly, allowing the printed boards to move into the assembly equipment only after they pass the measurement criteria set at SPI system.

"The equipment prevents us from populating boards that have inadequate solder paste deposits — effectively preventing solder related defects from occurring during the assembly process," said Amidon. "The 5700 SPI immediately identifies problems with the screen printer setup, allowing us to eliminate problems before they occur. Our first pass test yields have increased dramatically on low running prototype and production builds. The systems have allowed us to reduce non-value added labor by eliminating an SMT touch-up step from the process," he added.

The TROI 5700HL system offers in-line, high-resolution, high-speed, dual projection 3D solder paste inspection for large PCB boards, up to 500 x 460mm (20 x 18-in.). The TROI Series color 3D solder paste inspection (3D SPI) systems use the latest color algorithms to produce images in-line with the appearance of an actual PCB, providing customers with powerful quality control, accurate automated 3D inspection with convenient, easy-to-use and highly customizable software. Traditional 3D imaging only expresses the height as a color map. The TROI SPI utilizes Pemtron?s patented technology, connecting 2D colored images with 3D measuring data to provide detailed and accurate 3D color images.

According to the company, the intuitive software offers powerful inspection capability, with quick and easy programming in 5 to 10 minutes. The Gerber import module and user-friendly, step-by-step programming minimizes set-up time and ensures ease-of-use for users at any level. A graphical interface displays all key functions in one convenient window, eliminating the need to switch between multiple screens.

Fully Automated Operation
The TROI can be set to fully automated defect classification or operator classification mode. Classifying defects by operator provides convenient, easy-to-read results and full-color 2D and 3D solder paste views. In addition, statistical data collection is stored for process control in commonly used database formats, which users can sort, recall and print in various chart and graph formats. "The team at Pemtron has been incredibly responsive to our needs," said Amidon. "They have worked with us on every aspect of programming, providing us with the specific features we need. It is that kind of service that makes us confident working with Pemtron. The system has proven to be a very effective quality control tool for our organization and we look forward to working with them in the future for our SPI inspection needs."
