Thermals on SMD mechanical support?
I'd suggest follow the datasheet's instructions. Is it going in an enclosure? You should probably consider what forces will be applied to the connector and the support it will...

Prototying Methodology
This is perhaps higher level, but might as well add it to this thread. From an Agilent Appnote. oddbudman

Y/X EMI caps and a case for a DIY power supply
Your using a low frequency transformer from mains to low voltage dc. You probably don't need any X or Y caps for this application provided you follow good grounding, decoupling...

Inductive load switching with FET
Can you just use a higher voltage rated FET? (including a snubber would still be recommended) oddbudman

EMI reality check needed
toalan, Why bring 2 products to market? Won't this mean 2 lots of approval testing? 2 products to manage in production, 2 products to service once in the market ? Your...

EMI reality check needed
Tolan, can you explain your system a little more? Like input voltage/ power (PF?). Output voltages/power. Enclosure? Product Class? Isolation? oddbudman

Led driver
Series / Parallel with resistors. Switch them using a low side switch. Pwm with the switch for dimming.. Use the 12V source. oddbudman

Please give your opinion on my circuit/PCB Layout
Some notes: - your power tracks are too thin - for the through hole components is a good idea to fatten up the tracks when they run into the pad, this will make where the track...

Transistor basics: Load on collector or emitter?
rhoaste, It might be worth getting a copy of LTSpice and looking at some of its example circuits. There is info on the website sticky area on this software I believe. IMHO, Common...

Isolation recommendation
Ali, The tlp521 looks like a much much slower opto then the 6n137. Have you checked the serial speed from the meter ic? oddbudman
