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...

IPC/WHMA-A-620E-RL is a redline document showing the difference from IPC/WHMA-A-620D to IPC/WHMA-A-620E. IPC/WHMA-A-620E-RL provides a side-by-side comparison of the two documents and includes the figures and tables. The document shows deleted/changed text in the IPC/WHMA-A-620D pages and new/revised text in the IPC/WHMA-A-620E pages. Due to the complexity of this document, it is only available in...

This handbook is an essential resource for anyone involved in manufacturing or purchasing PCBs. Hundreds of real-world, full-color photos spotlight more than 650 PCB process defects, with causes and corrective actions for each. IPC-9121 supersedes the PCB sections of IPC-PE-740A. Released March 2016

IPC-7801 provides process control for solder reflow ovens by baseline and periodic verifications of oven profiles using a standard methodology to demonstrate acceptable oven performance repeatability. Equipment calibration and maintenance guidelines are provided. This standard is intended to verify the operating parameters of the reflow oven. This standard is not intended for the assembly product...

This standard describes the design and assembly challenges for implementing Bottom Termination surface mount Components (BTCs) whose external connections consist of metallized terminals that are an integral part of the component body. The BTCs in this document include all types and forms of bottom-only termination components intended for surface mounting. This includes such industry descriptive...

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...

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...

IPC-WP-024 is a white paper which discusses the issues associated with reliability of smart textiles (e-textiles structures) following multiple washing cycles and emphasizes efforts that industry and research laboratories must undertake to make e-textile structures more robust and able to be washed similarly to everyday textile products (e.g., underwear, clothing, home textiles and technical...

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.

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...
