The construction may be single, double, multilayered, or HDI technology and may include embedded (integrated)...

The definitive standard on printed board dimensioning and tolerancing is finally here! IPC-2615 comprehensively covers dimensioning and tolerancing of electronic packaging and is consistent with other IPC printed board standards such as IPC-6012A and IPC-2221A. The document includes fundamental dimensioning and tolerancing rules, positional, profile, orientation and form tolerances and detailed...

IPC-8401 standard provides guidelines for In-Mold Electronics (IME) manufacturing processes, part structures, candidate materials, and production test methods. In-Mold Electronics integrates printed electronics and electrical components into injection molded plastics, creating a three-dimensional smart molded structure. IME technology uses mass production processes, materials, and components. IME...

IPC-6012F Redline document shows the changes from IPC-6012E to IPC-6012F in a side-by-side comparison of the two documents. The IPC-6012F redline is available in both electronic and hardcopy format.

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...

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 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...

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...

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...

This specification covers qualification and performance requirements of rigid mass laminated panels for use in multilayer printed boards. Testing procedures and criteria are addressed. 21 pages. Released July 1994.

Covers the materials, qualification, certification and performance requirements for multilayer polymer thick film (PTF) printed, extrusion deposited, or otherwise applied conductor, insulator and through-hole technology. This specification may also be used for procurement of single and double-sided boards. 59 pages. Released November 1989.

Contains backplane design information from the fabrication and assembly perspective. Includes sections on design and documentation; fabrication; assembly; repair; and inspection. 17 pages. Revised September 1982.

Describes the usage of libraries within the processing and generation of information files. The data contained within covers both the definition and usage of internal (existing within the information file) and external libraries. The libraries can be used to make generated data more compact and facilitate data exchange and archival. The subroutines within a library can be used one or more times...

Describes an intelligent, digital data transfer format for describing component mounting information. Supplements IPC-D-350 and is for designers and assemblers. Data included are pin location, component orientation, etc. This document is frozen; no future updates are planned. 33 pages. Released January 1995.

Describes the relationship between elements used in electromechanical design and packaging of printed boards. Includes descriptions for logical and physical elements necessary as input to a design system, as well as the network of interconnection description between the various electronic parts. Provides the capability of describing all elements in their final form upon design completion. The...

Describes an intelligent, digital format for transfer of drawings between printed wiring board designers, manufacturers and customers. Also conveys additional requirements, guidelines and examples necessary to provide the data structures and concepts for drawing description in digital form. Supplements ANSI/IPC-D-350. Pertains to four basic types of drawings: master drawings, schematics, assembly...

Covers the information and data to be collected during the generation and use of phototools to improve artwork quality, thereby improving yields downstream. It also helps establish and maintain ISO 9000 certification and SPC by facilitating troubleshooting, standardizing the process for both experienced and inexperienced operators and by identifying process improvements for the ultimate...

Printed board flatness is largely affected by a change in intrinsic properties through exposure to variances in temperature. The worst case deviation of the printed board from flatness may be at room temperature, peak temperature during reflow, or at any temperature in between. Printed board flatness must therefore be characterized during the entire reflow thermal cycle, and not solely at room...

This document is a tool for a customer or supplier organization's internal audit group to assess a statistical process control (SPC) system against the requirements of IPC-9191.

Encapsulation, for the purpose of IPC-7621 standard, is defined as a low pressure molded thermoplastic, e.g., polyamide, which is brought to a liquid state and injection molded and (rather quickly) returned to a temperature below its melting point., forming a durable yet pliable (rubbery-like) form. The desired performance characteristics of low pressure molding (LPM) encapsulation depend on the...
