Ideal for electronic applications, like smartphone speakers or display frames, these liquid PSAs open up new possibilities in a variety of markets.
DELO has developed two liquid pressure-sensitive adhesives (PSAs) that reportedly have similar properties to (double-sided) adhesive tapes but are applied in liquid form. According to the company, DELO PHOTOBOND PS4130 and DELO KATIOBOND PS6372 can be dispensed easily and join components accurately with pressure. Components can then be handled immediately in a fully automated process, saving time and money during production. Ideal for electronic applications, like smartphone speakers or display frames, these liquid PSAs open up new possibilities in a variety of markets.
Adhesive tapes are used in a various bonding applications in the electronics industry. Their advantage is the immediate adhesion after two components have been pressed together. However, adhesive tapes have two major disadvantages. The first is when using small or complex tape geometries, automated handling becomes very time consuming or even impossible due to the low stiffness of the carrier material and the high adhesive force. The second challenge is that structures with a low fill factor, like those found in frame bonding, involve a large amount of waste from cutting the geometric shapes. This increases component costs.
