Elma Electronic, a pioneer in light guide and light guide with integrated LED combination technology, has introduced a new range of high temperature tolerant light guides with integrated LEDs.
The new, patented material and forming process called M-Pipe Technology, is ideal for soldering profiles conforming to IPC/JEDEC J-STD-G20, DIN 45802 and DIN EN60068-2-58. Previously, the temperatures commonly used with the industry standard profiles of IR and Vapour Phase soldering has been too high for light guides and light guides with integrated LEDs.
The Elma M-Pipes can withstand 260 degrees C for 40 seconds, or 200 degrees C for 180 seconds. This represents a substantial improvement in compatible solderability, with other components from the previous 235 degrees C and 185 degrees C, respectively. Additionally, because the SMD LED devices themselves are far removed from direct contact to the front panel, ESD protection is greatly increased over conventional LED designs, providing 7kV-12kV isolation, depending on the series.
