Method for an automated test station for mobile CPU modules

Disclosed is a method for an automated test station for mobile central processing unit (CPU) modules. Benefits include improved functionality and improved yield.

Background

         Automation is required in manufacturing process to achieve higher throughput with less factory space/time requirements. Automation is required during the test phase to eliminate human interaction, improve yield, and reduce cost. The goal is to achieve 100% automated test flow for mobile CPU products.

Description

         The disclosed method includes an automated tester and test station for mobile CPU modules.

The tester has a pneumatic front loading tray for loading and unloading the device under test (DUT). Loading and unloading can be performed by a human operator for a semi-manual mode or a robot for full automatic mode. An actuation mechanism inserts/deinserts the DUT into the test bed (see Figure 1).

         The communication subsystem reports the DUT’s individual serial number and the test Fail/Pass information to the manufacturing database. The recognition system is responsible for determining the DUT’s product type and downloading the appropriate testing software for that specific product (see Figure 2).

Advantages

         The disclosed method provides advantages, including:

•         Improved functionality due to enabling a 100% automated test of mobile CPU module products for manufacturing

•         Improved yield due to improved test flow compared to manual test oper...
