IPC J-STD-005B standard lists the requirements for qualification and characterization of solder paste. It references test methods, criteria, and metal content, viscosity, slump, solder ball, tack and wetting of solder pastes. Additional support is provided in IPC-HDBK-005, Guide to Solder Paste Assessment.
Now updated to align with IPC-7912A for end item DPMO, this document defines consistent methodologies for computation of in-process defects per million opportunities (DPMO) metrics for any evaluation stage in the assembly process. It is intended for use in measuring in-process assembly steps rather than end product determination. Calculation of completed item DPMO is addressed in IPC-7912A. A...
This standard prescribes the nomenclature, requirements and test methods for electronic grade solder alloys; for fluxed and non-fluxed bar, ribbon and powder solders for electronic soldering applications; and for ‘‘special’’ electronic grade solders. This is a quality control standard and is not intended to relate directly to the material’s performance in the manufacturing process. Solders for...
The IPC-7093A standard provides essential design and assembly guidance for implementing bottom termination components (BTCs). Specifically, IPC-7093A provides guidelines on critical design, materials, assembly, inspection, repair, quality, and reliability issues associated with BTCs.
The IPC-7525C standard provides guidance for the design and fabrication of stencils for solder paste and surface-mount adhesive with much of the content based on the experience of stencil designers, fabricators, and users.
IPC-9797A is the only industry-consensus standard for Requirements and Acceptance of Press-fit Pins. IPC-9797 describes materials, methods, tests and acceptance criteria for solderless press-fit pin connections. IPC-9797 is supported by IPC-HDBK-9798 “Handbook for Press-fit Standard for Automotive Requirements and other High-Reliability Applications” for those wanting additional information and...
Finally - an end to the confusion when calculating defect opportunities for benchmarking! For customers and manufacturers, it seems like every company has a unique way of calculating defects and then reporting on quality. In a complex electronics assembly operation, is it best to calculate using the number of components? The number of leads? What about solder joints? How can companies calculate...
This standard provides useful and practical information for developing thermal profiles to produce acceptable SnPb and Pb-free electronics assemblies. This revision expands the focus of the original standard from reflow profiling to include profiling for vapor phase, laser, selective soldering and wave soldering. The revision also includes a full-color troubleshooting guide for addressing common...
The IPC-A-640A standard provides acceptance requirements and technical insight that have been removed from acceptance standards for cable and wire harness assemblies incorporating optical fiber, optical cable and hybrid wiring technology. The IPC-A-640A is intended for use by the design engineer, manufacturing engineer, quality engineer and other individuals responsible for tailoring specific...
IPC-7526A handbook addresses understencil cleanliness during stencil printing, removal of solder paste from stencils following the cleaning process and misprint PCB board cleaning considerations.
This document describes the design and assembly challenges and ways to address those challenges for implementing 3D component technology. Recognizing the effects of combining multiple uncased semiconductor die elements in a single-package format can impact individual component characteristics and can dictate suitable assembly methodology. The information contained in this standard focuses on...
IPC-7094A describes the design and assembly challenges for implementing flip chip technology in a direct chip attach (DCA) assembly. The effect of bare-die or die-size components in a flip chip format has an impact on component characteristics and dictates the appropriate assembly methodology. The IPC-7094A standard focuses on design, assembly methodology, critical inspection, repair and...
The IPC-D-620A standard is the cable and wiring harness, systems-level design requirements companion to IPC/WHMA-A-620 and its associated space addendum. The intent of IPC-D-620A is to set forth the general design requirements for electrical wiring harnesses and cable assemblies. The IPC-D-620A is intended for use by the design engineer, manufacturing engineer, quality engineer, or other...
