CheckSum's Value Philosophy

1. In circuit test is a mature but still cost effective technology that will continue to be the primary means of electronics manufacturing test.

2. The fault spectrum of circuit boards has shifted significantly over the past 5 years.

3. Digital component defect rates have declined dramatically, reducing the need for expensive-to-implement digital vector testing.  

4. Boundary-scan and vectorless techniques such as TestJet Technology have mostly supplanted vectors.

5. Traditional in circuit testers, optimized around digital vector testing, require expensive fixtures, programs, and support.

6. In circuit testers with purchase and operating costs less than half those of traditional ICT provide test coverage well matched to today’s fault spectrum.

7. Using the Tester Portfolio Strategy, employing both low-cost and traditional ICT, allows test engineers to ensure that each test job is tooled for the appropriate tester, reducing total testing cost.

8. We recognize that privacy is important. We work with many companies that can be in competition. Please review our Privacy Policy.
