High-temperature tolerant light guides

Elma Electronic's new high-temperature tolerant light guides with integrated LEDs can withstand 260?C for 40s, or 200?C for 180s, which is an improvement in compatible solderability with other components rated at 235?C and 185?C, respectively.

Based on a patented material and forming process, called M-Pipe Technology, the M-Pipes light guides are suitable for soldering profiles conforming to IPC/JEDEC J-STD-G20, DIN 45802 and DIN EN60068-2-58. Previously, the temperatures commonly used with industry standard profiles for IR and vapor phase soldering were too high for light guides and light guides with integrated LEDs.

In addition, since the SMD LED devices themselves are far removed from direct contact to the front panel, ESD protection is significantly increased over conventional LED designs, providing 7-12kV isolation, depending on the series, said the company.

Available in different styles, the M-pipes come with or without additional solder tags or fixing pins; with single or dual LED versions in two different diameters and shapes; with or without adjacent-light radiating covers, and in both vertical and horizontal orientations. They are compatible with all standard automatic insertion equipment and are RoHS compliant.

Elma's M-pipes are priced at approximately 70 cents in volume, depending on configuration. Delivery is from stock to two weeks.
