One : exactly like in the lumilux data sheet and another one optimized for hand : soldering. : : See LED_5630.fp and LED_5630_manual.fp in the attachment. Wow, this is exactly what what I need. Thanks! I am thinking about modifying it to use one big pad for cathode and one for anode (instead of two smaller on each side). According to the datasheet, the pad near cathode is unconnected, so it can safely be joined to the cathode pad, and for the anode, both pads are interconnected inside the LED. What do you think about it?
