Hi there - I'm looking at having a small run of metal core PCBs made up. Can anybody recommend any manufacturers? Ideally ones that are happy to do low volume...

Thanks!

Geeeez, you are not asking for much! There ought to be something in the Boston area. But, this is getting into higher cost aerospace stuff!

They are often used with high-power LEDs.

That's what I plan on using them for... I plan on dissipating about 30W within about 20 square cm.

I suspect I'll be wanting to send these out to China as I don't care if my design gets ripped off and I'm paying for the parts myself.

"30W within about 20 square cm"

Your going to need a pretty sweet heatsink for this.

I'm sure you could find a decent supplier online, I know edaboard has quite a few links. Try and find one well recommended and make sure your clear with your specification when ordering - you don't want fr4 boards arriving air mail.

Big block of finned aluminum with 20MPH winds going past it.

Should be just fine - I just need good thermal coupling to that block - hence the MCPCB.

I just did a search of EDAboard and it came up with 0 results for MCPCB?

Here is one manufacturer I have found that does them. Not sure on pricing or quantity requirements.

As an alternative, a MCPCB is really nothing more than a flex circuit (or super-thin substrate) laminated onto an aluminum sheet (type .060"). You could look at getting a flex circuit done and then gluing it onto your heatsink. For construction I suggest placing holes beneath the LED's, so that the case of the LED comes in direct contact with the metal.
