The PCB is populated with two industry standard right angle SMT Leds, like Bivar's SMR series and two industry standard SMT LED's. The right angle SMT LEDs illuminate the lower two light pipe positions on the quad level assembly. The top two light pipe positions within the assembly align with traditional SMT LEDs in either 0603 or 0805 packages.
This innovative footprint allows for a quad-level indicator in less than 0.5" of front panel space allowed for use in aTCA and compact PCI (cPCI) mezzanine cards. There currently is no other solution recognized by PICMG for incorporation of 4 indicators in a single light pipe within the front panel envelope and PCB footprint for the aTCA specification. These products are all manufactured Pb free in compliance with RoHS material and processes, meeting global regulations for environmental responsibility.
