MIL-HDBK-339

Abstract

This handbook presents requirements for the management, design, and manufacturing control of custom monolithic large scale integrated circuits intended for use in high reliability space systems. In addition, this handbook presents the general requirements for the application or use of such devices in high reliability applications such as space systems and launch systems. This handbook is intended to provide the required guidance to ensure coordinated management of the design, development, application, procurement, control, and standardization of Custom Large Scale integrated Circuits (CLSICs) in order to eliminate any failures of such devices and to reduce any problems in their acquisition. <br>This handbook is basically intended to be listed as a guidance document in space vehicle acquisition contracts. However, the guidance information incorporated in the handbook may be followed as a matter of good management practice, Whether contractually suggested or not. Of course, the handbook or some of the requirements in the handbook, could be formally imposed as compliance by appropriate referencing. Even in that case, unless tailoring modifies the compliance required, the use of "should" instead of "shall" in all sections except Appendix C essentially turns the handbook requirements into guidance information only. In any case, the degree of compliance with the "should" requirements might be appropriately scheduled as agenda items at design reviews or technical interchange meetings. Resulting action items, Whether in scope or out of scope, would be handled the same as in scope or out of scope action items on any other subject. Nevertheless, the intended degree of compliance with the "should" requirements must be clearly stated in the contract, and not left to be interpreted after contract award. <br>When the space vehicle contractor procures CLSICs from another organization, the applicable provisions of this handbook should be included in the purchase order or subcontract. Specific CLSIC technical requirements and other design, fabrication, or test provisions which are directly applicable to a particular device are usually determined by the space vehicle contractor. The device requirements be formally imposed for compliance by the device supplier would be stated in a detailed technical requirement document prepared by the contractor, such as a detailed specification for the CLSIC. In that case, the general technical requirements stated in Appendix C of the handbook should be imposed by appropriate referencing of Appendix C in the detailed specification for the CLSIC (see Section <a>10</a>). <br>When this handbook is applied to CLSICs for use in other high reliability applications such as launch vehicles, or other equipment, the term space vehicle should be interpreted as the applicable vehicle or equipment. When this handbook is applied to the acquisition of custom very large scale integrated circuits (VLSIC), or to other device types, the term CLSIC should be interpreted as the applicable device. For the purposes of this handbook, LSIC, CLSIC, and VLSIC have the same requirements. <b><u>Intended Use:</u></b> It is intended that detailed specifications prepared for the procurement of specific devices would reference this general specification to incorporate the applicable requirements. LSICs covered by this specification are intended for use in space vehicles or in equipment with very high reliability requirements. The requirements stated in the specification are a composite of those that have been found to be cost effective for high reliability space vehicle applications. The general manufacturing process control requirements specified are intended to assure that a known quality product is manufactured and that all units in all production lots will have a uniform high reliability. The emphasis is on designing and manufacturing a reliable LSIC rather than screening defective LSICs from the production lot. The specification imposes the concept of product flight accreditation (see <a>3.1</a>) to assure that the LSICs satisfy all requirements that have been found necessary to assure successful space vehicle missions. <br>
