I send out this message earlier with the wrong e-mail address. The correct e-mail address for Dan is [log in to unmask] Thanks Hello, I am looking for a PCB fabrication house that can deliver at a bare minimum cost the requirements listed below. Please email all responses to [log in to unmask] Thanks Dan Pagano, CAD Manager, Samsung Telecommunications America Printed Circuit Board Requirements for RF Prototypes These requirements are intended to yield a quality printed circuit board are bare minimum cost. Modification of these requirements are encouraged to minimize cost. We are flexible. 1. Turnaround: 1 THRU 5 days 2. Number of Layers: 2 (ONE CORE W/COPPER CLADDING ON BOTH SIDES) 3. Core Material Types: Arlon GT250 or equivalent, Rodgers 4350 or equivalent 4. Core Thickness: RANGES FROM 20 TO 31 MILS TYPICALLY 5. Silkscreen: Yes (DESIRED, BUT NOT A REQUIREMENT) 6. Soldermask: No 7. Tin Lead Coating on Copper: PREFERRED, BUT NOT REQUIRED IF IT IS A COST DRIVER 8. Controlled Impedance: Yes, 50 ohms +/- 10% Coupons provided but impedance measurement not necessary unless cost effective. 9. Vias Required: Yes, PLATED THRU HOLES ONLY (12MIL AND 20MIL DRILLS ARE TYPICAL) 10. PCB Structure: STARTING PANEL SIZE IS 12"X18" TYPICAL. USEABLE AREA SHOULD BE AT LEAST 10"X16". The PCB panel should support a 10" x 16" useable area containing multiple unique designs (subcircuits) instantiated onto the same panel. The artwork data will reflect all the unique designs integrated 11. Routing: Each unique design or subcircuit on a panel may need to be routed in a particular manner to accommodate special components. Additionally each subcircuit within the panel will need to be removed from the panel prior to shipment. 12. Output formats: 274D, 274X, ODB++ 13. FTP CAPABILITY FOR FILE TRANSFER 14. EDGE COMPENSATION CAPABILITY - When are data indicates a 7 mil trace we expect the final product to have a 7 mil trace +/- process deviation. 15. INCREMENTAL COST FOR ADDITIONAL PANELS 16.
