This standard describes test methods by which both the surface conductors and attachment lands and plated-through holes may be evaluated for solderability. Most of this damage is not visible on the component surface.
This document contains 64 individual specification sheets that can be searched using keywords. From there, the designer chooses the appropriate sectional standard for a specific technology. This is known as the “popcorn” effect. Components such as thin fine-pitch devices and ball grid arrays could be damaged during SMT reflow when moisture trapped inside the component expands.
It has the potential to be suitable for aluminum wire bonding. It includes requirements for ENIG deposit thicknesses based on performance criteria. Kravene omfatter konstruktioner i alle tre klasser. This page was last edited on 7 August j-sts-020, at In addition, the tables and appendices have tjpe updated with the latest alloy information.
These are j-std-002 be used primarily for rigid and multilayer printed boards for electrical and electronic circuits. The series is built around the IPC se indholdsfortegnelse herGeneric Standard on Printed Board Design, the base document that covers all generic requirements for printed board design, regardless of materials.
IPC J-STD – Requirements for Soldering Fluxes – includes Amendment 1 Se indholdsfortegnelse her This standard prescribes general requirements for the classification and characterization of fluxes for high quality solder interconnections. IPC-A is the most widely used electronics assembly standard in the world. Additionally, wherever possible statements were modified to make readability easier and to enhance understanding — all without thpe any requirements.
Views Read Edit View history. Released27 pages. All five sectional standards are included with the series: Part 1 General Requirements has also been updated for ease of use and provides important direction and guidelines for all procedures.
This “C” revision has been updated to address intentional additions to a solder alloy and impurities in the alloy. The immersion gold protects the underlying nickel from oxidation or passivation over its intended life. It is not the intent of this standard to exclude any acceptable flux or soldering material; however, these materials must produce the desired electrical and metallurgical interconnection.
IPC-M includes seven documents. IPC – Printed Board Handling and Storage Guidelines Se indholdsfortegnelse her The industry’s sole guideline on the handling, packaging and storage of printed boards.
IPC-D S e indholdsfortegnelse her Establishes the general requirements for documentation necessary to fully describe end product printed boards, regardless of raw material, special fabrication requirements, layer count or end product usage. The expansion of trapped moisture can result in internal separation delamination of the plastic from the die or lead-frame, wire bond damage, die damage, and internal cracks. Revision E incorporates requirements for flexible cover materials used as a flexible dielectric protective layer over etched conductors and other conductive features.
Increasingly, semiconductors have been manufactured in smaller sizes. Containing full color photographs, this specification sets the requirements for the use of ENIG as a surface finish for printed boards.
Exposure to moisture and air contaminants, such as sulfur and chlorine, may negatively impact the useful life of the deposit. IPC-SM – Qualification and Performance Specification of Permanent Solder Mask and Flexible Cover Materials Se indholdsfortegnelse her Establishes the requirements for the evaluation of liquid and dry film solder mask material and for the filr of the acceptability of use on a standard printed board system.
Moisture sensitive devices are packaged in a moisture barrier antistatic bag with a desiccant and a moisture indicator card which is sealed. Additionally, to keep this revision D current with the global industry, eight specification sheets in the prior gile were removed as they are no longer utilized nor manufactured.

The immersion silver protects the underlying copper from oxidation over its intended shelf life. Many procedures have color illustrations to help the user understand the guide. Note that, in this revision, both a single thickness range is in place j-xtd-020 an upper limit for immersion silver thickness has been established.
