Product Design: PD17 - Testing in the Age of Global Production

Paul Messick, Avermetrics - Los Angeles, CA, USA

Good design is hard. Good testing should be easy. After designing a product, making it work, and making sure it meets all the specs, often little time is left to design the right tests to make sure the product is being built correctly at the factory. Instead, already overworked design engineers are asked at the last minute to come up with the factory production test regimen. Its no wonder that production testing is too often done poorly and commonly ends up looking eerily like R&D—costs and all.

Through this tutorial you will learn more about:

• How to do the “right amount” of testing, without false positives or false negatives
• Different ways to implement product testing in the factory
• How to make the most cost effective, yet thorough, end-to-end test solution for your products
• What to look out for when setting up production line tests both domestically and overseas
• How to manage production test remotely and better manage testing costs
• The difference between product engineering verification and production test
• How test fixtures can greatly speed up production testing
• Subassembly testing vs. Board-level testing vs. Finished Goods testing
• Design for Testing and Built-in test
• Testing high-volume products quickly and speed up testing low-volume products
• The non-linear relationship between test time and test expense
• Making testing count: collecting metrics and improving delivered products"
