How much pressure is necessary for adhesion of a pressure sensitive attached component to ensure a good bond? How much time is the pressure required?
A. The goal is to pressurize to achieve 100% wet-out of the adhesive. This is affected by size, shape, flexibility and tape placement of the components to be bonded. As a rule, 30 PSI or a 15 lb. roller for 0.5″ tape is used. More flexible components may need less pressure. The time factor is determined by the component flex, more than needs of the adhesive. The time is determined by the ability to flex the part such as to achieve 100% wet-out. Q.
