Parlex Meeting

11-04-2004

Adhesive process

• Parlex does not have a written detail work instruction on how to handle and apply adhesive film material (FM 73).

• Parlex called the manufacture Cytec and found out additional information on how to handle adhesive thought the process:

1. Adhesive should be placed in a vapor barrier bag at all times, to avoid any moisture.
2. When remove from freeze bring to room temp prior to applying
3. Apply 40 PSI (pressure)
4. Rap up material 30 to 60 minutes prior to bake of 250 degrees
5. After cleaning of connectors, connectors are to be baked to remove any moisture.

• Parlex will perform sample testing of the adhesive to achieve a bubble free process.

Parlex will notify SLAC of results

Create a detail work instruction and submit to SLAC for review

Review NCR’s, and Cause and Corrective Actions

11-04-04 LAT QA performed a final inspection on eight flex cable at the vendors; multiple anomalies were found reviewed discrepancies with Parlex QA department and Assemblers. Cables were to be reworked and shipped to SLAC.

SLAC received flex cables on 11-03-04 LAT QA performed inspection and found the exact same type of anomalies but now different locations of the cable.

1. Damaged connector pins

2. Foreign material in connector socket

3. Foreign material in between connector sockets

4. No test data to validate retest of cables

5. Missing micro sections and coupons

• Parlex QA Frank Golden could not provide any type of Cause and Corrective Action at this time.

• LAT QA will e-mail all NCR’s to Parlex

Omnectics connectors

• Parlex indicated that the omnectic connector rims are getting damaged due to test equipment.

• Parlex will change their test work instructions to incorporate inspections points after every mate and demate of the connectors.

• Parlex will create a mate demate log

• Parlex will create a retest data sheet for rework flex cables to validate retesting of flex cable .

• Parlex to create a rework work instructions and traveler for the removal and replace of any connectors

• SLAC LAT QA will ship connector saver to Parlex

• SLAC LAT QA to perform 100% inspection on all connectors (at Parlex)

SLAC’s requirements

• Notification of PMR/QCMR Product

Parlex QA (Frank Golden) could not indicate on how Parlex could implement requirement, but for the mean time QA Nancy Snow would fax QCMR’s to SLAC with in the required 24hr period.

LAT QA to provide Parlex a Fax No.

• Material Tractability

As of today Parlex still has not implemented any type of material trace ability on adhesive material. (Conformal coat, epoxy, adhesive film, and solder)

Parlex indicated that they could add the information in there work order traveler

• Qual Procedure

Parlex submitted Qual procedure to SLAC for review and approval as of today procedure has not been approved by SLAC

• Statement Of Work

Parlex has not received a revision 2, SOW from SLAC

LAT Tracker Engineering must work with Subcontracts to send rev 2 SOW ASAP. LAT QA to work with Tracker Engineering to ensure all revisions are incorporated.

• Redlines

SLAC to Redline the appropriate documentation to incorporate flex (pwb) Military Standard 5084

SLAC to Redline the appropriate documentation to incorporate connector savers.

Coupon and Micro-section

• Parlex does not know at this time as to why micro-sections exhibit material separation.

• GSFC will perform a SEM test on cross-section s/n 58-60

SEM results will be sent to Parlex

• GSFC will perform a barrel separation to detect as to why the material separation

Results will be sent to Parlex

• GSFC will perform additional inspection on micro-sections that are from scrap lots.

Parlex / SLAC to submit samples

• Parlex to confirm as to what holes are exhibited in the micro-sections, VIA or Connector.

• Parlex will physically mark the coupons as to where the locations of the coupons were physically located on the board.

Several weeks ago GSFC visited Parlex and reviewed (written doc) a polishing technique with Parlex QA department to insure that any anomalies would be detected at in process inspection rather than at the Customer (GSFC).

Parlex never implemented the polishing technique due to the time that was involved, and there production schedule.

• GSFC will check at their facility if they might possibly have a spare microscope to lend Parlex to help with the in process inspection of the micro-sections. If not they would provide the microscope model no. and manufactures name in order for Parlex to purchase one.
