The IPC-9202A, Material and Process Characterization/Qualification Test Protocol that records changes in Surface Insulation Resistance (SIR) on a representative sample of a printed circuit assembly (PCA). It quantifies any deleterious effects that might arise from solder flux or other process residues left on external surfaces after soldering, which can cause unwanted electro-chemical reactions...
The IPC-6903A standard provides 62 additional terms and definitions for the design and manufacture of printed electronics. The IPC-6903A standard creates a common language and understanding for the worldwide printed electronics community.
Strain gage testing allows for objective analysis of the strain and strain rate levels to which a surface mount package may be subjected to during assembly, test and operation. Excessive strain can result in various failure modes for different solder alloys, package types, surface finishes or laminate materials. This document describes specific guidelines for strain gage testing during the printed...
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.
The IPC-9709A standard guideline document establishes an Acoustic Emission (AE) method to enhance evaluation of the performance and reliability of surface mount attachments of electronic assemblies during mechanical loading.
Establishes mechanical drop and shock and test guidelines for assessing solder joint reliability of printed board assemblies from system to component level. This document addresses methods to define mechanical shock use-conditions, methods to define system level, system printed board level and component test board level testing that correlate to such use conditions and guidance on the use of...
Contains over 150 industry approved test techniques and procedures for chemical, mechanical, electrical, and environmental tests on all forms of printed boards and connectors. New and updated test methods are available for download at https://www.ipc.org/test-methods.
The IPC-9505 standard provides details of test methodologies for cleaning chemistry compatibility with electronic assembly materials that replace those in MIL-STD-202 Method 215 for testing electronic and electrical components such as capacitors, resistors, transformers and inductors. The test methods can also be used, when applicable, to parts not covererd by military specifications or drawings
The IPC/JEDEC-9301document is an effort to standardize and document some of the basic tenets of a typical Finite Element Analysis (FEA) model, as well as, to educate new designers (and in some cases even experienced designers) on the basic information and best practices that should be captured and provided to technical reviewers of the results of FEA data.
Tackling PCB cleanliness is a tough job; residues on printed circuit boards are directly related to the reliability of the produced hardware and can result in serious failures if not known or monitored. But how do you measure "cleanliness"? How clean is "clean"? The IPC-5701 provides guidance into how these issues should be approached and specified in purchasing documents, addressing levels of...
This standard is intended as a guideline in the proper preparation of a metallographic sample (microsection) of a printed board. The finished microsection is used for evaluating the quality of the laminate system and plated structures (e.g. PTHs and vias). Microsection sample preparation is regarded by many as a highly developed skill. The guidelines in this standard discuss the many variables and...
Mechanical bend and shock tests are routinely performed on SMT assemblies to ensure that they can sustain anticipated production, handling and end use conditions. The strains and strain rates applied to SMT assemblies during bend and shock testing can lead to a variety of failure modes in the vicinity of the solder joints. This document provides test methods to evaluate the susceptibility of...
IPC-8701 presents acceptance guidelines for the solar panel in final module assembly. The intent of this standard is to cover crystalline solar modules.Some of the content may be applicable to other photovoltaic modules such as thin film. The standard reviews and includes acceptance guidelines for incoming and finished frames, frame assembly, sealant, tape, junction box assembly, and bus bar...

This publication is intended to characterize the frature strength of a component's board level-interconnect by providing a common method of establishing the fracture resistance to flexural loading that may occur during conventional non-cyclic board assembly and test operations. The document is applicable to surface mount components attached to printed wiring boards using conventional solder reflow...
Survey-based study presents data and analysis on the EMS industry, examining trends in sources of revenue, revenue per employee, services offered, markets served, manufacturing technology, capital investment, spending on equipment and materials and market size including forecasts and potential for market expansion. This study is based on data provided by a representative sample of 120 EMS...
Every electronics manufacturer, whether an original equipment manufacturer (OEM) or electronics manufacturing services (EMS) company, must determine if the unpopulated printed boards entering the assembly process have an adequate level of cleanliness. The question of “how clean is clean enough?” is one that has no definitive answer, as there is no "golden number" for board cleanliness. The issue...
