IEC 61188-5-4:2007

IEC 61188-5-4:2007 addresses Printed boards and printed board assemblies - Design and use - Part 5-4: Attachment (land/joint) considerations - Components with J leads on two sides, making it relevant to engineering teams that define PCB attachment details and review solder-joint robustness. As a primary technical reference, it supports design decisions around land and joint considerations for components mounted on printed boards, helping align documentation, technical review, and compliance workflows. IEC 61188-5-4:2007 is especially useful where consistent attachment guidance is needed for product evaluation and manufacturing control.

IEC 61188-5-4:2007 standard overview

This document forms part of the IEC 61188 series on printed boards and printed board assemblies, with a specific focus on attachment considerations for components with J leads on two sides. Its purpose is generally to guide land and joint design choices so that assembly practices can be evaluated in a more consistent way during engineering validation and documented assessment. For organizations managing design-for-manufacture, procurement review, or technical compliance, it provides a structured reference for comparing attachment approaches and supporting operational consistency.

Applications of IEC 61188-5-4:2007

The technical scope is most relevant to electronics design, assembly engineering, and laboratory evaluation of printed board assemblies that use J-leaded components. It may be applied during footprint definition, solder-joint review, reliability-focused design checks, and production documentation for assemblies that require repeatable attachment performance. Procurement and quality teams may also use it as a compliance reference when evaluating supplied documentation or verifying that land patterns and joint-related decisions align with internal engineering specifications and testing workflows.

Why IEC 61188-5-4:2007 matters

Clear attachment guidance can reduce risk in printed board assembly programs by improving consistency in design interpretation, verification activities, and manufacturing handoff. By focusing on land and joint considerations for a defined component style, the document supports technical validation and conformity assessment preparation where solder attachment quality is important. It can also help teams maintain alignment between engineering documentation, production controls, and inspection criteria, which is valuable for quality assurance, procurement review, and controlled compliance workflows.
