HATS²™ Technology

7 Test Nets - Single Micro-Via Structures or Daisy Chain Nets Connected with Press-fit connectors Allows for Multiple Cycle Reflow Simulation & Thermal Shock. 36 Coupons (252 Test Nets) can fit into a HATS²™ Tester.

IPC-2221B Type "D" Coupons with 2 or 3 Daisy-chain Nets Connected with Press-fit Connectors Allows for Multiple Cycle Reflow Simulation and Thermal Shock. 72 IPC "D" Coupons (144 Nets for 2 net & 216 Nets for 3 net) can fit into a HATS²™ Tester.

Traditional HATS™ Coupons with 4 Daisy-chain Nets Connected with Press-fit Connectors Allows for Multiple Cycle Reflow Simulation and Thermal Shock. 36 of these (144 Test Nets) can fit into a HATS²™ tester.

7 Test Nets - Single Through-Via Structures or Daisy Chain Nets Connected with Press-fit connectors Allows for Multiple Cycle Reflow Simulation & Thermal Shock. 36 Coupons (252 Test Nets) can fit into a HATS²™ Tester.

HATS²™ Technology Platform was developed in 2020 as an update to the original HATS™ test technology, adding the capability to test a variety of industry accepted test coupons, the patented HATS²™ Single Via Coupon*, along with custom test coupons containing up to 7 test nets. The updated HATS²™ platform performs multiple cycle Convection Reflow Simulation up to 265°C in accordance with IPC-TM-650 Method 2.6.27 and other customer specific reflow profiles automatically. This Convection Reflow Simulation Methodology with In-Situ resistance measurements can detect cracks and separations in the via structures that occur during the high heat & material expansion of convection reflow which could reconnect mechanically at lower temperatures and not be detectable.

HATS²™ Technology also boasts an improved measurement sub-systems capable of high-current, micro-ohm precision, 4-wire resistance measurements. This allows testing of the patented HATS²™ Single Via Test Coupon*, Substrate based test coupons and Custom test coupons containing up to 7 test nets. This updated measurement subsystem also allows HATS²™ units to be able to test up to 72 of the IPC-2221B Type "D" coupons and 36 Traditional or Single Via HATS²™ coupons for both multiple cycle Convection Oven Reflow Simulation and Thermal Shock/Cycling. For more information about the patented HATS²™ Single Via Test Coupon*, please visit our dedicated HATS ² ™ Single Via page which can be found under the HATS ² ™ Technology heading.

HATS²™ Technology also includes new reporting software that allows customers to gain a clear understanding of test results both graphically and in tables. For more information, please view an EXAMPLE REPORT which can be found under the RESOURCES heading.
