This four-color document provides photographs and illustrations of the target, acceptable and nonconforming conditions that are either internally or externally observable on bare printed boards. Make sure your operators, inspectors, and engineers have the most current industry consensus information. With new or revised photographs and illustrations, revision J provides new coverage on topics such as microvia contact dimensions, plating, voiding and fill, along with updated and expanded coverage for dielectric removal etchback, smear and wicking , plating folds, surface plating for edge connectors, SMT and BGA pads, marking, hole registration, delamination, cap plating, via fill and flexible circuits.
Number of pages: Released May Scope This IPC-AJ document describes the target, acceptable, and nonconforming conditions that are either externally or internally observable on printed boards.
It represents the visual interpretation of minimum requirements set forth in various printed board specifications, e.
In order to properly apply and use the content of this document, the printed board should comply with the design requirements of the applicable IPC series document and the performance requirements of the applicable IPC series document. In the event the printed board does not comply with these or equivalent requirements, then the acceptance criteria should be as agreed between user and supplier AABUS. In some cases, such as voids or blisters, the actual condition is an internal phenomenon and is detectable from the exterior.
In some cases, these features may be visible from the exterior and require microsectioning in order to assess acceptability requirements. Specimens should be illuminated during evaluation to the extent needed for effective examination.
The illumination should be such that no shadow falls on the area of interest except those shadows caused by the specimen itself. The illustrations in this document portray specific criteria relating to the heading and subheading of each page, with brief descriptions of the acceptable and nonconforming conditions for each product class.
See 1. The visual quality acceptance criteria are intended to provide proper tools for the evaluation of visual anomalies. The illustrations and photographs in each situation are related to specific requirements. Supported by appropriate user requirements, this document should provide effective visual criteria to quality assurance and manufacturing personnel.
The value of this document lies in its use as a baseline document that may be modified by expansions, exceptions, and variations which may be appropriate for specific applications. This document is a tool for observing how a product may deviate due to variation in processes.
Refer to IPC AIT may be applicable to the evaluation of many of the dimensional characteristics illustrated in this document. Classification This standard recognizes that electrical and electronic products are subject to classifications by intended end-item use.
