The illustration shows the number of units that failed and the test step involved. By having this immediately available the source of the failure can be fixed to improve the First Pass Yield. ESCATEC reports that ESCADA has resulted in a significant improvement in FPY of around 25%.
“The ESCATEC Data Analysis enables us to spot manufacturing issues much earlier and correct them,” commented Thomas Eschenmoser, Section Head Test Engineering, ESCATEC. “This is a key part of our drive to catch problems early as part of our on-going programme to reduce production costs. These savings we can then pass on to customers. In addition, by having a detailed database of test results and issues, it becomes much easier to fix any problems that occur later in a product’s life. As a rule of thumb, fixing an issue once a product is out in the field can cost up to hundred times more than fixing at the component level during manufacture.”
