Most companies do a simple board swap for the customer, but then send the faulty boards back to the factory to be 'refurbished' - ie. run through the automated test rig and check every function is fully working. By doing that, an unnecessary board swap is 'free' to the manufacturer - which makes diagnosing problems in the store far easier - just keep swapping parts till the issue is resolved. When those boards end up back at the factory, they'll pass the test immediately and be able to be sent right out again for another repair. For boards that don't pass the test, sort them by the failure symptoms and suddenly repair becomes far easier - "these 50 need a new power supply IC, pay someone $25/hour on the rework station to do that, costing $3/board labour and $3/board in components". |
