Substrate-attach adhesives strength testing

Another method for measuring either die- or substrate-attach adhesion strength involves attaching a contact tool to the top of the die or substrate with an adhesive that is stronger than that of the die-attachment adhesive. The tool applies a vertical force until the die detaches from the substrate or until a minimum specified strength is achieved. The test method and failure criteria are specified in Method 2027 of MIL-STD-883F. i... 

Plastic parts with fabric attached to the surface must pass a series of durability tests including the cross-cut adhesion test. The cross-cut test is important in order to assess the adhesion strength of the fabric to the snbstrate plastic. This adhesion test provides a rating for the adhesion between all layers from the fabric surface down to the substrate plastic. The original ASTM standard D3 3 59-02 was developed to measme adhesion between thin paint films and flat, metal snbstrates (4). The cross-...
