Luciano, Checkout the following vendors: PCB123: www.pcb123.com PCB Express www.pcbexpress.com Both vendors offer a fairly cheap and quick turnaround on boards. You will need to use their software which is fairly simple and straightforward to use. They accept gerbers but for quick prototypes using their software will allow you to create a library which you can reuse for later courses. It will help by adding continuity to future courses. If you conform to their existing PCB templates you can get on their manufacturing shuttle (something akin to what we run at large Semiconductor foundries) which gets you your parts cheaper. Adding solder mask and silk screen is also optional. You can experiment with that when teaching your students about how it would affect the microwave properties with and without solder mask. Hope this helps.

I'm not sure they take Gerbers but it doesn't cost anything to ask. They can do drilling but no plated vias. Wolfgang "Luciano Boglione" <l.boglione@xxxxxxxx> Sent by: si-list-bounce@xxxxxxxxxxxxx 02/23/2009 01:15 PM To <si-list@xxxxxxxxxxxxx> cc Subject [SI-LIST] PCB Advise All, I teach a microwave class for undergrads and I have the opportunity to support a project whereby my student can design, fabricate, and test a simple distributed circuit. The idea is to give them some hands-on experience on microwave circuit and measurement. The plan is for each student to use ADS and generate a Gerber file for the vendor. To keep things simple, the FR4 would only have top/bottom copper layer, if possible without vias. This is my question: can you suggest the name of a vendor that can support fabrication of individual PCBs at competitive prices? I have never interfaced directly with vendors and I do not have a sense of who can do a good job for me. Also, my challenge is to fabricate individual PCBs (7 to be precise) rather than 10's or 100's copies of the same layout. Thank you in advance for your suggestions.
