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...

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...

Covers the information and data to be collected during the generation and use of phototools to improve artwork quality, thereby improving yields downstream. It also helps establish and maintain ISO 9000 certification and SPC by facilitating troubleshooting, standardizing the process for both experienced and inexperienced operators and by identifying process improvements for the ultimate...

Printed board flatness is largely affected by a change in intrinsic properties through exposure to variances in temperature. The worst case deviation of the printed board from flatness may be at room temperature, peak temperature during reflow, or at any temperature in between. Printed board flatness must therefore be characterized during the entire reflow thermal cycle, and not solely at room...

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.

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...

Encapsulation, for the purpose of IPC-7621 standard, is defined as a low pressure molded thermoplastic, e.g., polyamide, which is brought to a liquid state and injection molded and (rather quickly) returned to a temperature below its melting point., forming a durable yet pliable (rubbery-like) form. The desired performance characteristics of low pressure molding (LPM) encapsulation depend on the...

This standard establishes a Market Classification System and Level Classification System for printed electronics assemblies and provides a list of performance criteria and testing methods. It provides a standardized product category structure for designing and manufacturing printed electronics and assemblies which conform to industry-established performance metrics as determined by accepted...

This standard provides industry-approved terms and definitions to create a common language for users and suppliers to develop electronics products that utilize printed electronics alone or as additive processes combined with traditional rigid, flexible and rigid-flex PWB assemblies Released October 2015.

The IPC-6013D covers qualification and performance requirements for flexible printed boards designed to IPC-2221 and IPC-2223. The flexible printed board may be single-sided, double-sided, multilayer or rigid-flex multilayer. All of these constructions may include stiffeners, PTHs, microvias, and blind/buried vias. IPC-6013D incorporates new and updated requirements for final finishes, rigid-to...

Used in conjunction with IPC-2221, IPC-2223 establishes the specific requirements for the design of flexible printed boards and forms of component mounting and interconnecting structures. The flexible materials used in the structures are comprised of insulating films, reinforced and/or non-reinforced dielectric in combination with metallic materials. Revision D provides new design guidance and...
