students attending the certification-training program were from commercial production companies with no contractual performance for DoD. In addition to establishing product acceptance criteria, the specification also detailed methods for process control and defect reduction to be used in assembly. One hundred percent inspection was required unless specific conditions were met, so that sample-based inspection might be used with confidence. As a result of elimination of the various military standards, most DoD and termed highreliability production is defined through contractual implementation of the commercial IPC equivalent standards, such as J-STD-001, and IPC-A-610. 52.1.2.2 Space Production Requirements. Standards associated with space applications have significantly different purposes than process control documents commonly used for large-volume production electronics. For the purpose of space applications, there is seldom a large enough production volume to benefit from process development, and each individual product must be acceptable based on the environments experienced with space applications.These could be quite similar to the initial developments for DoD acceptance discussed earlier since they also involved space considerations. Current space application standards have evolved from NHB 5300 through to NASA-STD-8739.3, Soldered Electrical Connections. Additionally, the space user community has created a space addendum to the commercial standard J-STD-001 for the opportunity to employ consensus standards used by many of their contractors for various other programs. The addendum modifies requirements to a degree consistent with space interests and in effect makes the performance and acceptance requirements similar to that of the NASA-generated standard. 52.1.2.3 J-STD-001 and IPC-A-610 Industry Standards. These consensus industry association standards are widely recognized as the most common standards for requirements and workmanship for PCB assemblies, both nationally and internationally. They allow flexible definition of requirements based on three distinct classes of product, and the acceptability and performance requirements change based upon the contract provisions for the individual product as these classes are applied. 52.1.2.3.1 J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies. Since acquisition reform and elimination of the very commonly adopted military standards, IPC standards have filled the resulting void and have also brought with them additional valuable practices and perspectives from commercial producers. J-STD-001, Requirements for Soldered Electrical and Electronic Assemblies, was first released in April 1992 as a modification of the previous IPC-S-815, which had limited application, likely due to the competition from contractually imposed military and other industry-unique standards that were available to the users and managers at the time. IPC-S-815 had very similar criteria to that of the military baseline or General Requirements discussed earlier. The resulting J-STD-001 defines three levels of electronic assemblies based on the intended end-item use. The three classifications were established to reflect differences in consequences of failure, harshness of the operating environment, and expected term of operation. The three classes are summarized as follows:

CLASS 1: General Electronic Products This class includes products suitable for applications where the major requirement is function of the completed assembly. CLASS 2: Dedicated Service Electronic Products Class 2 includes products where continued performance and extended life is required, and for which uninterrupted service is desired but not critical. Typically the end-use environment would not cause failures. CLASS 3: High-Performance Electronic Products These include products where continued high performance or performance-on-demand is critical, equipment downtime cannot be tolerated, end-use environment may be uncommonly harsh, and the equipment must function when required. Examples include life support or other critical systems.

J-STD-001 addresses many of the same subjects as MIL-STD-2000, and in most cases for Class 1 and 2 production, the requirements are again similar to the General Requirements of the previous standards. The Class 3 requirements for the majority of the subject areas are similar to MIL-STD-2000, Detail Requirements. Since the deactivation of MIL-STD-2000 and the associated revisions, many contract performance requirements have been transitioned to this document and family of IPC standards. As with the predecessor documents, it should be recognized that a successful soldering process requires consistent materials and the ability to select the materials for a given process that will perform well in combination with compatibility for the application. As with acceptability, users may have the flexibility to establish their own requirements for these materials, but it would be difficult to find suppliers willing to create materials qualifications for anything other than a standardized definition. The following discussion provides a brief overview of the family of standardized criteria for materials associated with acceptable production standards. 52.1.2.3.2 J-STD-002, Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires. This standard prescribes the recommended test methods, defect definitions, acceptance criteria, and illustrations for assessing the solderability of electronic component leads, terminations, solid wire, stranded wire, lugs, and tabs. Solderability evaluations are made to verify that the solderability of component leads and terminations meets the requirements established in J-STD-002 and that subsequent storage has had limited adverse effect on the ability to solder components to an interconnect. Determination of solderability can be made at the time of manufacture, at receipt of the components by the user, or just prior to assembly and soldering. Similar to J-STD-001, J-STD-002 has its origin with military standards, which in this case was MIL-STD-202, Method 208. It defines standardized methods of evaluating the ability of a surface to accept solder and in addition defines the durability of the solderable surface with three categories of product and related conditioning to determine the product performance before soldering. Category 1 is the least demanding performance, where the product would be used soon after testing, and Category 3 is applied where the product may be stored for extended periods of time before soldering. The intent is to identify solderability problems before the expense of production is added or the production schedule is delayed while waiting for solderable replacement parts. For a more detailed discussion of solderability and the related issues, refer to Sec. 52.5. 52.1.2.3.3 J-STD-003, Solderability Tests for Printed Boards. J-STD- 003, Solderability Tests for Printed Boards, was released in April 1992 to complement the requirements of J-STD-001. This standard prescribes the recommended test methods, defect definitions, and illustrations for assessing the solderability of printed board surface conductors, attachment lands, and plated-through holes. The solderability determination is made to verify that the PCB fabrication processes and subsequent storage have had no adverse effect on the solderability of those portions of the PCB intended to be soldered. This is determined by evaluation of the solderability specimen portion of a board, or representative coupon, that has been processed as part of the panel of boards and subsequently removed for testing per the method selected. The objective of the solderability test methods described in J-STD-003 is to determine the ability of printed board surface conductors, attachment lands, and plated-through holes to wet easily with solder and to withstand the rigors of the PCB assembly processes. For a more detailed discussion of solderability issues, refer to Sec. 52.5. 52.1.2.3.4 J-STD-004, Requirements for Soldering Fluxes. J-STD-004 prescribes general requirements for the classification and testing of soldering fluxes for high-quality interconnections. This standard is a flux characterization, quality control, and procurement document for solder flux and flux-containing material. This standard defines the classification of soldering materials through specifications of test methods and inspection criteria. These materials include liquid flux, paste flux, solderpaste
