FREMONT, Calif., 26 Oct. 2006. Elma Electronic in Fremont, Calif., is introducing a range of temperature-tolerant light guides with integrated light-emitting diodes (LEDs).
This material and forming process, called M-Pipe Technology, is for soldering profiles conforming to IPC/JEDEC J-STD-G20, DIN 45802 and DIN EN60068-2-58. Previously, the temperatures commonly used with this industry standard profiles of IR and vapor-phase soldering has been too high for light guides and light guides with integrated LEDs.
The Elma M-Pipes can withstand 260 degrees Celsius for 40 seconds, or 200 C for 180 seconds. This represents a substantial improvement in compatible solderability with other components from the previous 235 C and 185 C respectively.
Additionally, because the SMD LED devices themselves are far removed from direct contact to the front panel, electrostatic discharge protection increases over conventional LED designs, providing 7-to-12-kilovolt isolation, depending on the series.
Available in different styles, the Elma 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. M-Pipes are compatible with all standard automatic insertion equipment and were designed from their inception to be completely RoHS compliant.
