Offers designers and...

During mass soldering, it is important that all solder joints reach the minimum soldering (reflow) temperature to assure metallurgical bonding of the solder alloy and the base metals to be soldered. Metallurgical bonding requires that both surfaces to be soldered, as well as the solder, reach this minimum soldering temperature for a sufficient time to allow the wetting of the solder surfaces. This...

The IPC-7091 intends to provide useful and practical information to those who are designing, developing or using 3D-packaged semiconductor components or those who are considering 3D package implementation. The 3D semiconductor package may include multiple die elements—some homogeneous and some heterogeneous. The package may also include several discrete passive SMT devices, some of which are...

The successor to the IPC-SM-782A is here! The document covers land pattern design for all types of passive and active components, including resistors, capacitors, MELFs, SSOPs, TSSOPs, QFPs, BGAs, QFNs and SONs. The standard provides many brand new features, including an intelligent land pattern naming convention, zero component rotations for CAD systems, and a set of three separate land pattern...

This document describes the design and assembly challenges for implementing passive and active components, in either formed or placed methodology, into a printed board. It provides useful and practical information to decision makers of formed or placed, passive or active components and helps establish inspection techniques, testing processes, and reliability validations. Users will also learn...

Status of the technology discussion on the various methodologies for mounting and interconnecting active devices to a variety of substrate materials is summarized in this document. Reviews mounting techniques of tape automated bonding (TAB), chip on board (COB) and flip chip. Examinations of the most commonly used substrate options of laminate, ceramic and silicon are also reviewed. Editor: John...

IPC-2292 standard establishes specific requirements for the design of printed electronic applications and their forms of component mounting and interconnecting structures on flexible substrates. Flexible substrates, as pertaining to IPC-2292 standard, are materials or devices which have some amount of flexibility or bendability (not rigid) but are not considered to be stretchable (e.g., fabrics...

The IPC-2231 standard provides guidelines for establishing a best practice methodology for use in developing a formal DFX (Design for Manufacturing, Fabrication, Assembly, Testability, Cost, Reliability, Environment, Reuse) process for layout of printed board assemblies that utilize surface mount and through hole devices.

IPC-1791 provides minimum requirements, policies and procedures for printed board design, fabricating and assembly organizations and/or companies to become trusted sources for markets requiring high levels of confidence in the integrity of delivered products. Demonstration of the ability to meet and maintain the requirements of IPC-1791 as trusted design, fabricator or assembly organization...

The IPC-WP-026 white paper explores blockchain as an emerging technology that has a core strength in providing an immutable, auditable, transparent and secure environment for data exchanges. These advantages make it a prime candidate for implementation in the electronics industry. The IPC-WP-026 white paper explores blockchain and its limitations and challenges. It also provides a few directions...

Manufacturers of high reliability electronics have been working for many years to mitigate the deleterious effects of tin whisker formation. One highly effective means to suppress the growth of tin whiskers is to replace the pure tin plating with reflowed tin-lead solder. One approach is to fully consume the tin plating by tin-lead solder during the SMT reflow process. This phenomenon of tin...

The lack of a uniform component traceability standard has caused an unnecessary consumption of resources (e.g., time, people, money, etc.) to track events or parts to their sources and to remedy any quality, reliability, etc., issues. Lack of a standard has also made it difficult to uniformly create and appropriately enforce the necessary contracts. This standard establishes minimum requirements...
