High-performance products
for advanced customer needs

Sales of smartphones and tablet computers are increasing rapidly. And consumer expectations for these mobile devices are rising just as fast. They expect them to become ever more portable, yet more robust and reliable. Henkel’s Adhesive Technologies business sector helps manufacturers to meet these challenges by developing materials for handheld device assembly and semiconductor packaging.

Henkel Adhesive Technologies manufactures materials for a wide range of applications – from inside the chip to the outside of the mobile device. Underfills, for example, help ensure that if your mobile device is dropped, it will still work. Electrically conductive solders are used to secure semiconductor devices to circuit boards and establish the electrical connections so that data and information can be processed and transmitted by mobile electronic devices. Structural adhesives bond the device housing, buttons, connectors and displays. “Henkel adhesives can be found in most smartphones and tablets around the globe,” says Andrew J. Bardon, Senior Application Engineer in Technical Customer Service.

Customized global solutions

Henkel has several development laboratories located around the globe, each set up to validate our materials in equipment similar to what our customers use. Working in our labs in Rocky Hill, Connecticut, USA, Bardon states: “We test our materials in the same way as our customers, which gives us great insight on how to improve our formulations.”

Henkel’s adhesives are dispensed using special equipment, including an innovative Loctite 4530 HC dispensing robot. This unit was developed by Henkel specifically for dispensing structural adhesives, not only for testing but also for high-volume manufacturing at customers. Andrew Bardon continually checks that the robot is dispensing the adhesive correctly – applying an ultrafine strand with a diameter of just 0.35 millimeters at a speed of 50 millimeters per second. The Loctite 4530 HC is offered to customers together with Henkel adhesives as a complete system solution that perfectly matches their advanced needs.

Henkel teams comprised of researchers, engineers and sales managers support manufacturers throughout the product design and production process. “We test our products on prototypes and often participate in the design of next-generation mobile devices,” states Bardon. “ After we complete development with our customers’ design centers, we hand off the materials for production testing and implementation in Asia, where the handheld devices are generally produced on a large scale.”

Rapid response, technological expertise, and timely customer interaction are essential for successful collaboration in fast-paced markets, like electronics. Thus, we have strategically located our Henkel material design and test laboratories close to customers. For example, the site in Irvine, California, USA, is closely located to customer design centers, while our Shanghai design center is close to the manufacturing hubs in China. This way, products can be engineered and tested around the clock.
