IPC-TM-650 2.3.17.1

Description / Abstract: This test is to measure the flow properties of cast adhesive freefilms or coverfilms used in the manufacture of flexible circuitry. The test also provides a measure of the squeeze out, which might be expected to occur around terminal pads or other boundary spaces. It is not possible to define a universal set of laminating conditions that suit all of the various adhesive types. This test is dependent on sample preparation, which is consistent with good industry practice and in accordance with the suppliers' suggested laminating procedures.
