LED Array Holders simplify the LED installation process and reduce installation time due to compression contacts that eliminate hand soldering. The holders allow customers to install LED arrays quickly into fixtures. The LED array holder is produced by one of the world’s top suppliers of connectors and interconnect components.

Producers and marketers of LED luminaires and fixtures want an aesthetical and white product. The reflectivity of the white LED holder also contributes to the light output of the light unit. Luminaire makers also require a solution where the holder does not crack during assembly into the fixture. The producers of the LED array holders developed a solution that will allow them to reflow solder the array into the holder in a simply and reliable way. This all together requires engineering plastics with excellent mechanical, optical and thermal performance.

DSM’s Stanyl ForTii F11C outperforms a liquid crystal polymer (LCP), originally considered for this application, in several aspects. The material has high impact strength and its good flow properties enable it to fill a mold originally designed for an LCP. With Stanyl ForTii you can produce parts with higher weld line strength, resulting in less cracking during assembling.

Stanyl ForTii F11C’s high deflection temperature under load (305°C), required to minimize distortion during reflow soldering, is better than that of other rival thermoplastics such as polyphthalamide (PPA) and LCP’s. Stanyl ForTii F11C has a UL94 V-0 flammability rating, and the special version developed by DSM for LED array holders also has the white color and reflectivity required.

Stanyl ForTii helps to bring to market an easy to assemble, halogen free lower-cost LED.
