The customer in this case specialized in developing and manufacturing small and medium-sized LCD touch modules. They produce TFT, OLED and LCM modules but acquired touch screen and optical bonding services from third party suppliers.

CHALLENGE

For this project, the client had highly specific needs. Their original suppliers were not able to accept special designs, small quantities, or technical modifications. After the customer learned that the original supplier would not customize the design, they contacted AMT, hoping that we could solve the problem. Our sales person immediately contacted them by phone after receiving the request. They identified the pain points and analyzed the issues in the original design. They then developed an innovative plan to provide the very best solution to meet the client's needs.

SOLUTION

The challenge in this case was the product depth of industrial plastic frames. Because of the design and the depth of the frame, rollers cannot be used for bonding. Additionally, most plastic frames are black which absorb light. Therefore UV cannot be used to cure LOCA or “liquid optically clear adhesive”.

Lucent Gel SOCA, or “solid optically clear adhesive”, produced by AMT, is the best solution for this type of product. Lucent Gel is Silicon-based, which is soft and pliable with good defoaming (debubble) performance. Coupled with a special bonding fixture, it is suitable for optical bonding of plastic frames at all depths. Last but not least, if there is any problem in the manufacturing process, Lucent Gel has significantly better reworkability than LOCA.

OUTCOME

The client trusted AMT’s professional technology and sent prototypes to us immediately. AMT was able to begin prototype production that met the customer’s unique requirements within a week of receiving the sample products. We are proud of our professional capabilities and always willing and excited to help our customers.
