IPC - Association Connecting Electronics Industries
Scope
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.
