|Vitrox super-fast AXI system. |
Automatic x-ray inspection (AXI) represents the ultimate inspection system for the high-quality production line, and often, one machine alone is not enough. Javad Electronic Manufacturing Services (San Jose, California) recently completed the successful implementation of the ViTrox V810 3-D In-line Automated X-Ray Inspection (AXI) System at its state-of-the-art facility in San Jose, California. Javad EMS prides itself on its quality, from equipment to processes, employees and finished products.
According to Gary Walker, Javad Vice President, the new system cuts program development times in half and provides inspection speeds up to four times faster than the EMS provider's previous AXI system. "The V810 has not compromised on performance," he said. In fact, it has proven to yield better call rates compared to the other vendors. ViTrox has delivered an efficient, production proven solution with the V810."
JEMS has more than 40,000 sq. ft. of manufacturing space in the heart of Silicon Valley, and has updated it to the highest standards of electronic manufacturing services, communication, client support, employee comfort and training.
Four SMT Lines
The company runs four continuous flow SMT lines complete with inline 3-D solder paste inspection and AOI. These lines are highly flexible, allowing for diverse and complex products using the latest in component packaging technologies to be assembled and with quick changeover between products, enabling high-mix, low- to medium-volume production.
Before evaluating the ViTrox V810 AXI system, Javad was well aware of the strong structural defect coverage benefits of 3-D X-ray from its experience with other AXI equipment. From this past experience, Javad also was quite familiar with the common struggles faced when trying to implement this equipment in production. The company has high expectations for this new AXI equipment that is capable of fast program development, high inspection speeds, wide test coverage, low false calls and provides user-friendly interfaces.
Evaluatng Ease of Operation
In selecting the V810, Javad focused on evaluating the ease in which programs could be created while still concentrating on the system's coverage capabilities on leading-edge devices such as Stacked BGAs (Package-on -Package), connectors and heavily shaded components. The system has proven to be a top performer in 3-D AXI solutions. In addition, the V810 was recognized not only for providing the fastest speeds without compromising test coverage, but also for its image clarity, focus accuracy and repeatability as well as its special algorithms. All of these features have allowed the machine to stand out among its competitors, in addition to being chosen as the preferred solution by Javad.
Walker continued, "We assemble high-reliability products that have applications ranging from use 12,000 ft. below the surface of the ocean, to space-launched vehicles, and everything in between. Javad EMS believes that the V810 will contribute to the great product quality that we deliver to our customers and (will provide) a high return on investment."
Top and Bottom Views
Besides the ability to inspect and separate the top- and bottom-side images clearly, V810's Proprietary Auto Focus technology also enables the system to intelligently focus on the desired z-height without any mechanical movement from X-ray or stage. Javad also found the "Virtual Live" that provides users with the flexibility of live content browsing on the board by region to be very useful for failure and defect analysis.
When compared to competitive automated X-ray inspection (AXI) equipment, Javad finds that it's possible to further enhance the system utilization time in production since it is embedded with an auto-adjustment feature with which the confirmation, diagnostic and adjustment (CD&A) is run automatically without interrupting the system. Other types of AXI equipment require up to five hours of down time to make adjustments every few weeks in order to optimize the inspection call rate, thus affecting production usage. The V810 is capable of detecting many defects including shorts, opens, missing components, non-wetting, billboards, tombstones, lifted leads, solder balls, voiding, insufficient solder, reversed tantalum capacitor and excess solder. It has the ability to inspect the toughest hidden joint defects commonly found on the production line such as head-in-pillow, package-on-package, PTH and various types of connector joint defects to a standard far beyond other AXI machines on the market.
Verification Tool Solution
In addition, the inspection system is coupled with the ViTrox Verification Tool Solution (VVTS), which is equipped with SPC capability for reviewing and verifying inspection results and images with which good reference images and previously classified defect images are provided for more effective defect comparison. The company's advanced SPC tool, "VDSPC", can be applied to multiple lines and machines for overall defect/chart analysis.
Both Javad and ViTrox believe in close collaboration in order to provide the best quality to their customers. "ViTrox and its sales channel partners have the sincere thanks from each of us at Javad EMS for their exceptional job in the after-sales support and installation, which are just as important as the sale and performance of the equipment itself," added Walker.
