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. WE PREFER THE VENDOR PROCURE THE MATERIAL
