9 production faults are unavoidable during assembly process (DPMO) a test coverage of 100% is unrealistic (technical) slip-through is the amount of boards which are passing the test strategy and still may contain production faults at customer side slip-through will be calculated in advance slip-through explained

10 test methods X-ray AOI FPT ICT BST combination test FT IEEE & IEEE

11 DfT – way of working test strategy “as is”: AOI + FPT + BST test strategy “as advised”: AOI + FPT + EBS test quality x 4,7

12 NIKHEF - HAM base promise 2 via structural tests the slip-through can be reduced to 0,08 % less functional test or no functional test at all at board level

13 the most cost efficient structural test method which can also test components functionally what can be tested? pcba with mixed analogue and digital technology pcba with only analogue technology cost reduction versus functional testing automated testing minimum troubleshoot effort EBS test – Extended Boundary Scan test
