For those interested in touring a PCB fabrication house, (in the LA
Calif area), Please post to me (not the list).
The Orange Chapter of the International Microelectronic And Packaging
Society (IMAPS-OC) and the IPC Designers council is having a tour of
McCurdy Circuits (Anaheim, Ca) on 27 April 2000.
Dave Hoover of McCurdy Circuits, will make a presentation on
Controlled Impedance Boards and PCB Surface Finishes.
