> Subject:      [TN] Copper Core PWB's
>
> We are currently experiencing difficulty in locating a production
> supplier for a copper core board we are using in a newly developed
> product (estimated usage 250 - 2,500 annually).  The past supplier who
> provided a quality circuit at an economical price has decided to move
> out of the copper core business as a result of the increase in their
> telecommunications business for standard product.
>
> We located two suppliers who have experience with this technology;
> however, our cost have increased 4X and the performance to date has
> been
> less than satisfactory.  Problems to date have revolved around,
> drilling
> and routing of the .045 copper plate, selective routing on the top and
> bottom side of the board to the copper plate, and plating to our
> specification.  Unfortunately, we have opened our tolerances up as
> much
> as possible and our new suppliers are still experiencing problems.
>
> If you have knowledge of a supplier through experience with this
> technology or are a supplier, please contact me at the address below.
> The attached Word file details the requirements of the board.  If you
> would like a .ps or .gbr of the detail drawings let me know.  Thanks
> in
> advance!
