1.1 The hermetic integrity of hybrid microcircuit packages is an important material or parts acceptance requirement. Determination of this parameter should be made before the hybrid circuit is assembled and sealed inside the package.

1.2 This test method covers a test for leaks in a package that is intended to be hermetically sealed after hybrid circuit assembly. Various types of hybrid packages may be tested by this test method. The test method is nondestructive and therefore suitable for 100% inspection.

1.3 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
