Thanks folks, I will keep everyone up to date as to the progress of the order. In the interim, anyone who is interested kindly PM me your shipping information so I can make my list as we go.

Again, thanks for the interest.

Dear Jason,
I had ordered two sets of the semiconductors on PMI, but the consignment is lost in transit. Can you supply full set of semiconductors along with the boards? Other parts can be sourced locally. At what price?
Also, how to mount the pcb on a heat sink, 200mm (Horizontal)*100mm (Vertical), optimally? How do you envisage the mounting?

Mounting is intended to be vertical with the MOSFETs placed towards the bottom of the heat sink. I believe at least one prior purchaser is mounting them horizontally. That would likely be fine too, though I have not personally tried that.

As for the semiconductors, they aren't expensive or hard to source. You can even use other devices so long as the pin-out is the same and the voltage ratings aren't exceeded. Everything I have specified is current production from Fairchild, and possibly other manufacturers, with the exception of the output MOSFETs. For those we are looking for Renesas devices and I have been getting those from Tayda Electronics.

I haven't really given much thought to including parts with these boards. I don't want to be on the hook for a pile of components if the boards don't move in a timely manner. It becomes a situation for me; I'm sure some would spend a little extra to have the semiconductors included, others have their own already or prefer to source their own. I'd prefer not to pay shipping and duty on numerous small orders to fill requests on demand, but can't really afford to buy a full set for each board and wait for them to sell either. If I were to include semiconductors on an 'as needed / requested' basis it would have to be worth the extra time, effort and expense on my part. This might sound expensive, but my thoughts would be an extra $25USD per board to have the semiconductors included. Some of the semiconductors I'm currently out of (the outputs specifically) and would have to wait for them to arrive which might delay the dispatch of the boards as well, just so anyone seriously thinking about it knows about the likelihood of a delay in shipment.

In any event, let me know your thoughts.
