[time-nuts] PCB for frequency dividers

[dave powis]

David,

Have you had a look at http://www.top-tec-pcb.com/eng/index_.html?

I use them for my boards, and running a quick estimate using the details you've published.  They aren't quite at the price you've indicated, but for a slightly higher number they do get significantly cheaper.  There are some items which could affect the price that you haven't quoted, such the number of buried vias, but you can input all that in their on-line calculator - use the Power-Pool quote system, not the prototype quote link.

Regards,
Dave, G4HUP

Subject: [time-nuts] PCB for frequency dividers

I'm going to place an order for the PCB for my frequency divider in the next
few days.   If I can get a batch of ten ordered the cost will be about USD60
each plus postage to wherever you are.   PCB is four layer, 5" by 3.5", pads
will be electrolytic Ni/Au (this house doesn't charge extra for that).

The price goes down as the numbers go up of course.   If anyone thinks they
can better this price, I'm happy to ship the gerbers and NC drill files.

I never did hear back from Magnus about the circuit driving the selectors on
the '4051, so that stays as it is.

I have one firm request from Norman J McSweyn.

If anyone else would like to order a PCB please could you email me directly
(rather than on list) at

david dot partridge at dsl dot pipex dot com

I also have a few spare of the '4017 dividers and lots of BAV99 which I'm
happy to pass on at cost to me.

Cheers
Dave
