COULD YOU PLEASE KINDLY MAKE NECESSARY PREPARATION OF YOUR COMPANY INFORMATION AS WE RECEIVED VERY DETAIL INFORMATION REQUIRED BY OUR CUSTOMER.PLEASE ADVISE VIA RETURN WHETHER IT IS POSSIBLE FOR YOU TO GET ALL DETAIL INFORMATION WHILS WE ARE VISITING YOUR FACTORY. THANK YOU. With Best Regards Somsak O.

It is encouraging to see that we both use the same IPC documents to reference our standards and guidelines. I would like to add that IPC-RB-276 is further supplemented by the IPC-6011 series. As you are aware our vendor survey does not cover PCB fabrication/manufacturing issues. It is appreciated that you have supplied a sample Process Audit Report for the PCB vendor survey/audit scheduled for this November. I did notice on this report that there was no Form # or Revision on the document. We are looking for the link back to your internal documents, please advise. Our greater concern is the quality of the PCB manufacturer that you will be selecting. Naturally we have been in close contact with our current PCB suppliers and we know the product quality. In considering your upcoming audit of your PCB supplier please be aware that in addition to an audit/survey copy, we would like to request the following items: Company Name & Point of Contact Location of Supplier Company History (products, delivery, capability, capacity etc) List of internal Workmanship Standards Manufacturing Process Manufacturing Order/Travelers (sample is ok) Testing & Inspection And potentially for future use, PCB Coupon samples of: System, Sensor and Illumination PCB's, microsectioned according to IPC-TM-650. We are looking for all IPC-A-600 Class 2 acceptability criteria. Please ensure that adequate micro sectioning methods are used, for if improperly done these methods can conceal anomalies rather than revealing them. The ESD protocols for your assembly areas are appropriate. All personnel are conscious of the potential ESD hazards and are wearing wrist straps. It is further reassuring to hear that you would make provisions in your Class 10K SMT and Reflow areas to accommodate the wrist straps for our product as well. It would be requested that some language be added to your current internal ESD plan(?) that describes this added measure for our ZAPPER product. I am assuming however, that procedure # 90-00015 Handling, Storage, Packaging, Preservation and Delivery...contains this requirement, please advise. Wichet, during our visit/survey last week my colleagues and I were very impressed with the Stars facility. Your efforts should be applauded as we recognized throughout the facility, the process controls, documentation, accept/reject criteria for every process station we visited.

According to your e-mail to Mr. Somsak & Mr. Polsak regarding " PCB Fabrication , Vendor Supplier Survey & ESD Requirements" ,I would like to provide the information which PCB manufacturer use as standards to you as following. 1. What standards or processes do you use for Class 2 PCB Fabrication? a.. IPC-RB-276 "Qualification and Performance Specification for rigid board". b.. IPC-ML-950 Rev. C "Performance and Specification of Multilayer Printed Wiring Board" 2. What standards or processes do you use for Class 2 HASL ( Hot Air Solder Leveling ). QQ-S-571 for standards SN63? a.. IPC-S-804 Rev.A "Solderability Test Method for Printed Wiring Board." b.. QQ-S-571"Standard for 60Sn/40Pb." 3. If applicable , what standards or processes do you use for Class 2 Preconditioning of the PCB. a.. IPC-S-804 Rev.A "Solderability Test Method for Printed Wiring Board". b.. QQ-S-571 "Standards for 60 Sn/40Pb." 4. What standards or processes do you use for Class 2 PCB Test Methods for Micro sectioning.IPC-TM-650 Micro sectioning? a.. IPC-TM-650"Test Method Manual". b.. IPC-RB-276 c.. IPC-ML-950 5.What standards or processes do you use for Class 2 PCB Test Method for Continuity Testing? a.. Reference to MIL55110 Rev.E . For open circuitry is 20 Ohm and short circuitry is 5 Mega Ohm. 6.What standards or processes do you use for Class 2 PCB Solder Mask aplication? a.. IPC-SM-840 Rev. B"Qualification and Performance of Permanent Polymer Coating ( Solder Mask ) for Printed Board." 7. Other standards that PCB manufactuer use as. a.. IPC-D-300 Rev.G"Printed Board Dimension and Tolerance". b.. IPC-A-600 Rev.E "Acceptability of Printed Board". 8. As we are using the approved PCB manufacturer by Alactel ,so that we do not have the vendor survey information for this PCB manufacturer yet. But we do have plan to perfrom audit for this PCB manufacturer by ourselves on dated 22-Nov-1999. We also send the sample of the audit report for other part manufacturer which we conducted such audit for your reference in the attached file. 9. ESD. We reference to EIA standard : EIA-625 for ESD practice in STARS. 9.1 According to your concern that the skin is not contact with a conductive path to ground and consequently may discharge through an assembly when handle. We would like to inform that we will be implementing wrist strap for operator throughout assembly line in order to avoid such problem. Please kindly review the above issue and advise any comment you may have.
