Current State

www.ieee-astr.org September 28- 30 2016, Pensacola Beach, Florida 3

Current Practices Will Not Support Future Demand

• One part currently undergoes HASS testingo Dedicated Chamber and 3 Bay Tester

o 4 products tested at once

o Fixtures “permanently” installed in chamber parts loaded into fixtures

o Multiple electrical connections made in the fixture

o Complex product – extensive test times to allow for electrical coverage during HASS testing

o Significant Floor Space required to support a single product.

Problem Statement

www.ieee-astr.org September 28- 30 2016, Pensacola Beach, Florida 4

How do we optimize throughput while minimizing capital expenditure and assuring quality?

• 5 distinctly shaped products require testing• What are the common elements we can leverage?• What will change-over look like?• What is the maximum number of products

that can he tested at one time?• Smallest footprint possible with easy

product flow• What do the operators think?
