Simultaneous Testing Provides Actionable Data... Continued from previous page


mized for automation. These functional test systems provide simultaneous testing and programming at a single high-throughput station, making them excellent for nonstop 24/7 production lines. VanNewkirk states that CheckSum provides 300 percent faster board test and programming times than its competitors, making the company a true val- ue-add partner. These fast systems solve throughput


challenges by using multi-core ICT, Multi- Writer™ flash programming, parallel func- tional test, which is inline-suitable for 24/7 production lines and fully scalable with flex- ible testing architecture. Capturing function- al test information earlier in the line has a significant benefit: real-time feedback that allows manufacturers to pause production before more defective boards are pro- duced.


MultiWriter is CheckSum’s on-


board programming technology that was first developed 12 years ago. By programming an entire panel in par- allel, the company can deliver the fastest possible programming solu- tion to customers. “Now, after pro- gramming a billion chips and han- dling panels of 100-up-plus, Check- Sum is recognized as the innovator in gang programming,” says Van- Newkirk. Next, the company developed


MultiCore ICT. CheckSum offers multiple V12 ICT modules operating in parallel, both inline and offline, to test boards simultaneously. For high- volume manufacturers of panelized boards, MultiCore ICT continues to offer a major throughput advantage. More recently, CheckSum intro-


duced its newest development: paral- lel functional test. Like MultiWriter, parallel functional test has unlimited scalability architecture, testing a panel of 40 boards in the same time it takes to test one singulated board.


Fixturing Solutions. CheckSum of- fers complete turnkey packages that are ready for production when they land on the receiving dock. The com- pany can provide design and drilling for all CheckSum fixture types, full ICT test programming for CheckSum systems, custom fixturing for unique test requirements, direct engineer-to- engineer support for turnkey proj- ects, design for test analysis, and strain analysis. The company pro- vides the following fixture options: pneumatic, fully automated inline fixture systems that test up to 3,000 connections; dual-level automated pneumatic fixture systems; vacuum fixture systems; mechanical advan- tage fixture systems; and benchtop pneumatic fixture systems.


In-System Programming Solu- tions. CheckSum’s MultiWriter tech- nology is used to program up to 384 serial flash devices in parallel. Capa- bilities include simultaneous flash programming of up to 384 devices, device libraries for virtually every se- rial programmable device, security and data encryption to protect cus- tomers’ IP, and serial numbers, cal constants, and margin verification. These systems come standard


with high signal integrity with short wire lengths and galvanic isolation of power and programming signals per location. Programming, byte-by-byte verification, chip erase, blank check- ing, CRC verification, and device locking are all supported. CheckSum is also a sensor spe-


cialist and provides an all-in-one so- lution optimized for sensor manufac-

turers. The company’s board test and pro- gramming solutions offer ICT and flash functional test at board level for increased throughput. Being able to test many boards in parallel is a critical capability for manu- facturers looking to meet the increasing de- mand for sensors with as little rework as possible. CheckSum’s three parallel testing solu-


tions provide the opportunity for customers to maximize throughput and provide imme- diate feedback to line. Success in parallel testing requires more than just a tester, it requires a partner. Contact: CheckSum, LLC, 6120 195th


CheckSum can provide custom fixturing for unique test requirements, as well as design for test analysis.
