HATS™ Plated-through Hole Reliability Testing Technology has been recognized and utilized since 2003.
Over the years, a number of papers have been published regarding the technology and its bene
HATS™ coupons are daisy chain coupons and can be electrically tested with other thermal
shock technologies that electrically test daisy chains, including dual chamber. The HATS™ tester uses high speed air as the heat transfer ( uid) mechanism to heat and cool the test coupons along with a Keithley 2400 system meter to make accurate and repeatable 4-wire resistance
measurements of the coupons.
Other technologies use different mechanisms like oil, nitrogen, sand or internal conduction to transfer heat to the coupons which results in different transfer rates. Alternative thermal shock methods utilize electrical measurement techniques (2-wire, 3-wire, etc.) and meters/switching systems that may not have the accuracy and repeatability of the HATS™ tester. These differences mean that HATS™ testing technology and cannot be directly compared to other non-dual-chamber thermal shock technologies. HATS™ testers use air as the heat transfer mechanism just like the tried and true method used by dual chamber thermal shock testers for the last 50+ years.
HATS™ testing requires a HATS™ tester. HATS™ testers can test 36 (4 net) coupons for a total of
144 daisy chain test nets per test run. Doing 1000 cycles of that many coupons/nets with other technologies can take weeks if not months due to their limited capacity. The HATS™ tester does
1000 cycles of 36 coupons/144 nets in less than a week. Carefully research the methodologies out there before you decide.
