This standard is intended as a guideline in the proper preparation of a metallographic sample (microsection) of a printed board. The finished microsection is used for evaluating the quality of the laminate system and plated structures (e.g. PTHs and vias). Microsection sample preparation is regarded by many as a highly developed skill. The guidelines in this standard discuss the many variables and...

The European Union’s Restriction of Hazardous Substances (RoHS) legislation has had a profound impact on the electronics industry. One of the restricted substances, lead (Pb), is commonly used in alloys with tin for component finishes, printed board finishes and solders. Pb-free materials directly affect product performance, reliability and service life in many ways. There have been numerous...

This standard, developed jointly by IPC and the Electronic Industries Association (EIA) establishes the construction detail requirements for balls and other terminal structures on Ball Grid Array (BGA) packages.

IPC JEDEC J-STD-020 is used to determine what moisture-sensitivity-level (MSL) classification level should be used so that surface mount devices (SMDs) can be properly packaged, stored and handled to avoid subsequent thermal and mechanical damage during the assembly solder reflow attachment and/or repair operation. J-STD-020 covers components to be processed at higher temperatures for lead-free...

The IPC-9505 standard provides details of test methodologies for cleaning chemistry compatibility with electronic assembly materials that replace those in MIL-STD-202 Method 215 for testing electronic and electrical components such as capacitors, resistors, transformers and inductors. The test methods can also be used, when applicable, to parts not covererd by military specifications or drawings

J-STD-075 picks up where J-STD-020 left off by providing test methods to classify worst-case thermal process limitations for electronic components. Classification is referenced to common industry wave and reflow solder profiles including lead-free processing. The classifications represent maximum process sensitivity levels and do not establish rework conditions or recommended processes for an...

Electrical, thermal and mechanical chip design parameters and methodologies are covered in the standard, as well as the reliability aspects associated with...

This standard establishes construction detail requirements for bumps and other terminal structures used for Flip Chip Scale carriers. The specific standards for different terminations are appropriately matched to a particular interconnection process and include such diverse terminations as solder bumps, columns, non-melting stand-offs and conductive polymer deposits. The document articulates a set...

This specification covers qualification and performance of rigid printed boards, including single-sided, double-sided, with or without plated-through holes, multilayer with or without blind/buried vias and metal core boards. It addresses final finish and surface plating coating requirements, conductors, holes/vias, frequency of acceptance testing and quality conformance as well as electrical...

Establishes the requirements for the evaluation of liquid and dry film solder mask material and for the determination of the acceptability of use on a standard printed board system. IPC-SM-840 provides two classes of requirements, T and H, to reflect functional performance requirements and testing severity based on industry/end use requirements. Coverage is given to adhesion, material qualification...

This document examines key issues in advanced packaging techniques. Provides information on what types of parts are available, the techniques and processes necessary for their proper use, possible advantages/disadvantages or problems, how to start implementation and where to find additional information. 138 pages.

Provides information on multichip module technology, including parametric data, design and manufacturing information and a proposed categorization of various approaches to multichip interconnect substrate technologies based on dielectric family. 120 pages. Released August 1992.

This document will provide insight into the theory behind tin whisker formation as it is known today and, based on this knowledge, potential mitigation practices that may delay the onset of, or prevent tin whisker formation. The potential effectiveness of various mitigation practices will also be briefly discussed. References behind each of the theories and mitigation practices are provided. It...

IPC J-STD-001F is recognized worldwide as the sole industry-consensus standard covering soldering materials and processes. This revision includes support for both traditional solder alloys and for lead-free manufacturing. Examples of some of the significant changes are revision to plated-through hole, PTH, minimum fill requirements; criteria for two new SMT termination types; and expanded...

Provides information on design characteristics and the application of solderless surface mount connectors, including conductive adhesives to aid IC package and board interconnection. 34 pages. Released January 1994.

J-STD-001E is recognized worldwide as the sole industry-consensus standard covering soldering materials and processes. This revision includes support for lead free manufacturing, in addition to easier to understand criteria for materials, methods and verification for producing quality soldered interconnections and assemblies. The requirements for all three classes of construction are included...

This standard prescribes test methods, defect definitions, acceptance criteria, and illustrations for assessing the solderability of electronic component leads, terminations, solid wires, stranded wires, lugs and tabs. A test method for the resistance to dissolution/dewetting of metallization is also included in the standard. Intended for use by both vendors and users, J-STD-002D was developed by...
