5 Will the Government be providing any of the test equipment NO

6 IPC Class 2 or 3? IPC CLASS 2

7 ROHS? Yes or no? NO

8 Clean / wash PCB’s for flux? Clean using MRF's standard practices.

9 Any testing on the PCB’s post production? Each CCA will be tested as per SOW.

10 Several vendors have stated that the build or mechanical drawings are missing. Pick and place file included in the revised Technical Data Package (TDP). All available files have been provided.

11 The reference under the NSN shows 213809. A vendor has inquired as to if there is an NSN. Doesn't have an NSN.

There is both an excel and a pdf version of the BOM. However there appears to be a quantity difference between the 2 versions.

Could the Government clarify which version of the BOM is accurate? Use PL213809 REV 1.

13 What is the name of the software required to open the technical data files?

They are Gerber files. There are many programs available that circuit card manufactures use to open these files, too many to list.

Any MFR that is capable of building circuit cards, can open these files.

14 Are there Labeling and Serial Numbering requirements? No SN requirement, all other labeling info is included in the TDP.

15 What are the Quality Clauses i.e. Class I, II or III, IPC, J-STD? Same question, IPC class II.

16 Is there a Conformal Coating requirement? If so, what type? No conformal coating.

17 Is it possible that the USG would consider Acceptance at Origin instead of Destination?

Acceptance at TYAD.

18 Is the USG aware of any of the materials identified on the BOM as being obsolete or DMS?

vendor will identify obsolete items.

19 Have any Item Equivalents or Replacements for materials on the BOM already been approved by the USG?

Equivalents / replacements must be proposed.

20 Have any waivers or ECPs been granted for this item that are not included in the TDP? If so, will that information be provided?

There are no ECPs for this CCA.

21 Please confirm that there will be no delay in acceptance between the initial delivery of 10 each and the delivery of the remaining 2,954 each?

3. Delivery Schedule/Shipping Address

a. The contractor shall fabricate, assemble, test, and deliver 10 each CCA’s as soon as possible, but not later than ninety (90) calendar days from the date of contract award. The remaining 2,954 CCA’s shall be delivered at an even rate, on a monthly basis, ensuring completed delivery within one (1) year of contract award for a total of 2,964 Power Interface CCA’s.

Early and Partial Delivery will be accepted.

22 Are there any special solder mask, silkscreen, or plating requirements?

Solder mask - Green

Silkscreen - White

Plating - HASL (Non RoHS)

23 Are there any fabrication drawings, assembly drawings, or other files that have been omitted from the Technical Data Package (TDP)

All available files have been included in the TDP. Our technical personnel have confirmed that all files can be opened using Eagle Software.

24 What is the PCB material? FR4

25 What is the overall thickness of the board? 0.062"

26 How much copper on each of the four layers? 1oz

27 Is there a requirement for the PCB finish to be Matte or Gloss? Matte finish.

28 Is a Hot Air Solder Leveling (HASL) or Electoless Nickel Immersion Gold (ENIG) or other finish required? HASL, but ENIG is acceptable

Follow up to Question 26:

"Q&A set 6 states for item 26 that there is 1 oz of copper on each of the four copper layers. However, in the "213809.HYP" file the thickness of the "SIGNAL" layers is stated as T=0.00070. A copper thickness of 0.0007" is 1/2oz while a copper thickness of 0.0014 (twice as much) would be for 1 oz. Can the Government please clarify this?"

Use 1oz or .5oz as required.

30 Do the page limitation outlined for each volume in the submission include a cover page?

The page limitations do not include a cover page. A cover page may be included to identify the volume. However, any additional information will not be considered upon review and evaluation.

Question 1 states that part CommenAVX part # 245602670000829H+ has a 12- 14 week lead time and allows for substitute parts to be used. If a substitute part is used, are changes to the gerber files/Technical Data Package authorized to accommodate changes in dimension or size?

Any substitute part used must be an exact replacement in fit, form, and function. Importat to note is that consideration has been given to the extended lead time. As a result, the delivery of the first ten CCA's has been changed from 90 days to 120 days. Changes to the TDP to accomodate substitute parts ARE NOT authorized.
