For Electronic Manufacturing Services
(EMS) firms, achieving high yields on manufactured
circuit boards and sub-assemblies is imperative. But,
testing to achieve a higher yield must be done efficiently.
That's just what ScanWorks with its JTAG capabilities
has provided for a number of EMS firms who now are
deeply committed to boundary scan test processes.
Jabil, for
example, reduced its ICT test development costs significantly
when it teamed ScanWorks with Agilent Technologies'
3070 ICT systems. Another EMS, Reptron
Manufacturing Services, compiled a thorough study
that demonstrated the accelerated return on investment
(ROI) it received from ScanWorks. Moreover, SMT,
a contract manufacturer, faced an unacceptable failure
rate on a circuit board with poor ICT test coverage
because of limited physical access. Once SMT
combined boundary scan and ICT, the failure rate dropped
precipitously.
OEMs working with EMS firms have found that deploying
ScanWorks early in the manufacturing process pays
off handsomely throughout a product's life cycle.
ADC, for instance, saw
its yields on lots of manufactured circuit boards
increase from the 10 to 60 percent range to well over
90 percent when it worked with its EMS to implement
ScanWorks. As a startup, Neoscale
saved significant debug time when it began using ScanWorks
on the circuit boards it received from its EMS .

"Our boards have no in-circuit testing (ICT) capability due to extremely high chip density," said John Howard, manufacturing manager for the BATG Division of ADC Telecom Inc., in Cleveland, OH. "There was no room for test points and physical access to the fine pitch pins is very limited. It was taking us up to a month to test, troubleshoot and bring up a batch of 50 boards.With the testability services we've received from ASSET InterTech's Ensure DFT Division, as well as our contractors use of the ASSET boundary scan test and in-system programming system, we can now bring up a batch of boards in hours versus days." 
Agilent
ScanWorks® Completes Successful Assessment at
Jabil Circuit. One of the first places electronics
manufacturers look to reduce expenses is through the
elimination of redundant effort. Jabil Circuit, Inc.
one of the top Electronic Manufacturing Services providers
was first to perform early assessment of Agilent Technologies’
and ASSET InterTech’s joint effort to enable
manufacturers to leverage boundary scan tests across
the product life cycle. 
The ScanWorks® JTAG system tracks down faults missed by other test methods. For a start-up electronic company like NeoScale Systems, Inc., a provider of enterprise storage security solutions, time is of the essence. That's why NeoScale is making full use of ASSET's ScanWorks JTAG test and programming system. 
When contract manufacturer SMT Unlimited L. P. ran into a high failure rate on a densely populated telecommunications board, Hom-Ming Chang, Vice President of Test Engineering and Information Systems, wasn't sure what he could do to solve the problem. "We really don't have boundary scan (IEEE 1149.1 JTAG) expertise on our staff here," Mr. Chang said. "So we turned to Ensure DFT to help us and they developed a test program for us that's been very successful. In one case, we've gone from having an unacceptably high failure rate to a failure rate close to zero. I'd say that was very successful." 
EMS firm finds that JTAG testing with ScanWorks pays for itself by saving "money, time and company resources." Accelerated ROI: The ScanWorks JTAG system reduced troubleshooting time by 1,457 percent! Because of the nature of its business, Reptron Manufacturing Services, an electronics manufacturing services (EMS) company with its headquarters in Tampa, Fla., and a major manufacturing facility in Hibbing, MN, had to be certain that its investment in boundary-scan test equipment would not only generate a healthy return on investment, but it would do so over a very short period of time. The firm found its solution in ASSET's ScanWorks boundary-scan test and in-system programming environment.
