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...
IPC JEDEC J-STD-020 is used to determine what moisture-sensitivity-level (MSL) classification level should be used so that surface mount devices (SMDs) can be properly packaged, stored and handled to avoid subsequent thermal and mechanical damage during the assembly solder reflow attachment and/or repair operation. J-STD-020 covers components to be processed at higher temperatures for lead-free...
J-STD-075 picks up where J-STD-020 left off by providing test methods to classify worst-case thermal process limitations for electronic components. Classification is referenced to common industry wave and reflow solder profiles including lead-free processing. The classifications represent maximum process sensitivity levels and do not establish rework conditions or recommended processes for an...
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...
This specification covers qualification and performance of rigid printed boards, including single-sided, double-sided, with or without plated-through holes, multilayer with or without blind/buried vias and metal core boards. It addresses final finish and surface plating coating requirements, conductors, holes/vias, frequency of acceptance testing and quality conformance as well as electrical...
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.
Discusses the many variables and problems associated with the process--from sample removal to micro-etch-- and the variables common to high volume microsection. The process variables and problems are organized so that the reader can research a specific issue or overview the variables of a process area. 31 pages. Released October 1993.
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...
Provides information on multichip module technology, including parametric data, design and manufacturing information and a proposed categorization of various approaches to multichip interconnect substrate technologies based on dielectric family. 120 pages. Released August 1992.
IPC-9631 addresses concerns and considerations related to IPC-TM-650, Method 2.6.27, Thermal Stress, Convection Reflow Assembly Simulation. This document describes how the test method is intended for use and the rationale behind some of the protocols and requirements. This document was developed with the understanding that the test method will require special equipment and the proper set-up 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...
Provides information on design characteristics and the application of solderless surface mount connectors, including conductive adhesives to aid IC package and board interconnection. 34 pages. Released January 1994.
Establishes the requirements for the evaluation of liquid and dry film solder mask material and for the determination of the acceptability of use on a standard printed board system. IPC-SM-840 provides two classes of requirements, T and H, to reflect functional performance requirements and testing severity based on industry/end use requirements. Coverage is given to adhesion, material qualification...
Printed board cleanliness has historically been an unknown factor in the quality assessment of unpopulated (bare) printed boards; this has often been attributed to a lack of understanding of materials and processes. This document addresses the various printed board fabrication processes and how each may impact, directly or indirectly, the final cleanliness of packaged bare printed boards and...
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...
