JESD22-B107, Revision D, on Marking Permanency for Integrated Circuits, has just been released at the beginning of March. It replaces all previous editions of the standard.
The JESD22 series is a set of test methods for integrated circuits that are widely used in the semiconductor industry. It is composed of both JESD22-A and JESD22-B series standards.
The B107 test method provides two tests for determining the marking permanency of ink marked integrated circuits. A new non-destructive tape test method is introduced to quickly determine marking integrity. The test method also specifies a resistance to solvents method based upon MIL-STD-883 Test Method 2015.
