The document includes fundamental dimensioning and tolerancing rules, positional, profile, orientation and form tolerances and detailed...

This document is intended to clarify terms used in the area of fluid dispensing. As is often the case, different terms are used by different manufacturers to convey a similar meaning. Common interchangeable terms are shown in parenthesis and the reader should not infer one term is preferred over the other.

IPC-9716 provides requirements for automated optical inspection (AOI) systems to define, set up, establish, and apply process control for manufacturing printed board assemblies, including general and specific process and AOI system conditions. Requirements include inspection parameters, lighting conditions, calibration, detectability, resolution, threshold limits, program setups, measurement...

The IPC-5262 prescribes the minimum design, critical process and acceptance requirements for the application of polymeric materials to electrical/electronic components, modules, printed wiring assemblies and other elements thereof. The intent of IPC-5262 is to establish a baseline of requirements, procedures, practices and process attributes based on lessons learned and best practices that have...

Printed board quality encompasses many parameters, cleanliness being one important parameter. This document defines the recommended general requirements for the cleanliness of unpopulated (bare) single, double-sided and multilayer printed boards. Coverage is given to Ion Chromatography (IC) testing and Ionic cleanliness testing for process control. 6 pages. Released December 2009.

Printed board cleanliness has historically been an unknown factor in the quality assessment of unpopulated (bare) printed boards; this has often been attributed to a lack of understanding of materials and processes. This document addresses the various printed board fabrication processes and how each may impact, directly or indirectly, the final cleanliness of packaged bare printed boards and...

Every electronics manufacturer, whether an original equipment manufacturer (OEM) or electronics manufacturing services (EMS) company, must determine if the unpopulated printed boards entering the assembly process have an adequate level of cleanliness. The question of “how clean is clean enough?” is one that has no definitive answer, as there is no "golden number" for board cleanliness. The issue...

Tackling PCB cleanliness is a tough job; residues on printed circuit boards are directly related to the reliability of the produced hardware and can result in serious failures if not known or monitored. But how do you measure "cleanliness"? How clean is "clean"? The IPC-5701 provides guidance into how these issues should be approached and specified in purchasing documents, addressing levels of...

This guideline covers the requirements for resin coated copper foil intended for use in the formation of high density interconnect surface microvias for printed boards and printed board assemblies. 19 pages. Released November 2007.

The IPC-4555 standard covers the requirements and testing for organic solderability preservatives (OSP) processes for printed boards to be used primarily for electrical and electronic circuits. Details for lead free soldering are covered in IPC-4555

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. It also establishes a set of designations and expectations for product performance. A large variety of terminal structures are recognized for a wide range of applications ranging from...

IPC-4121 provides industry-approved guidelines for selecting core constructions for multilayer printed wiring boards (PWBs). The specification sheets in the document categorize the different core constructions by laminate type and nominal thickness. The constructions are rated for characteristics such as dielectric constant (DK), dimensional stability (DS), flatness, smoothness and drillability...

Establishes the specific requirements for organic mounting structures used to interconnect chip components, which in combination form the completed functional organic single-chip module (SCM-L) or organic multichip module (MCM-L) assembly. Includes the quality and reliability assurance requirements that must be met for their acquisition. For use with IPC-6011. 25 pages. Released February 1998.

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...

Used in conjunction with IPC-2221A, IPC-2225 establishes the requirements and other considerations (thermal, electrical, electromechanical and mechanical) for the design of Single Chip Module (SCM-L), MCM or MCM-L assemblies. Key concepts include adhesive interconnection information, typical die attach materials, microvia material properties and relationships with DFM and DFE.

Defines a machine readable input format for Computer Numerical Control (CNC) drilling and routing machine tools used by the printed wiring board industry. The format may be used to transfer drilling and routing information between printed board designers, manufacturers and users or as the output CNC standard from converters that expand higher level design input such as IPC-D-350 data. Provides a...
