jedev Components such as thin fine-pitch devices and ball grid arrays could be damaged during SMT reflow when moisture trapped inside the component expands.

Part 3 is IPCB and includes procedures for modifying assemblies and accomplishing laminate and conductor repairs. The guidelines in this document are intended to protect printed boards from contamination, physical damage, solderability degradation and moisture uptake.

Proper packaging is a requirement. Moisture sensitive devices are packaged in a moisture barrier antistatic bag with a desiccant and a moisture indicator card which is sealed.

This four-color document provides photographs and illustrations of the target, acceptable and nonconforming conditions that are either internally or externally observable on bare printed boards. It may also be used when press fit connections are employed and for zero insertion force ZIF edge connectors. IPC J-STD – Solderability Tests for Component Leads, Terminations, Lugs, Terminals and Wires – Includes Amendment 1 Se indholdsfortegnelse her This standard prescribes test methods, defect definitions, acceptance criteria, and illustrations for assessing the solderability of electronic component leads, terminations, solid wires, stranded wires, lugs and tabs.

This “C” revision has been updated to address intentional additions to a solder alloy and impurities in the alloy. Coverage is given to adhesion, material qualification, resistances to solvents, and electrical requirements.

Released with Amendment 1: The IPC is supplemented by the appropriate sectional performance specification: IPC J-STD – Solderability Tests for Printed Boards Se indholdsfortegnelse her J-STDC prescribes test methods, defect definitions and illustrations for assessing the solderability of printed board surface conductors, attachment lands, and plated-through holes utilizing either tin-lead or lead-free solders. Inkluderer Amendment 1, august This document contains 64 individual specification sheets that can be searched using keywords.

The tool also allows for modification of dimensional attributes of IPC approved land patterns. This single volume includes all previously published changes and several new procedures for BGAs including reballing and flex-print repair.

Part 1 General Requirements has also been updated for ease of use and provides important direction and guidelines for all procedures. J-STD covers components to be processed at higher temperatures for lead-free and lower temperature Sn-Pb assemblies. This specification is a full-color document that is intended for use by the supplier or printed board fabricator, plating chemistry supplier, contract assembler or EMS facility and the original jedecc manufacturer OEM.

It has the potential to be suitable for aluminum wire bonding. Additionally, nedec keep this revision D current with the global industry, eight specification sheets in the prior revision were removed as they are no longer utilized nor manufactured.

Components must be mounted and reflowed within the allowable period of time floor life out of the bag. This guide is provided in a three ring binder for easy updating.

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.

It is a multifunctional surface finish, applicable to soldering, aluminum wire bonding, press fit connections, and as a contact surface.

Released27 pages. The ENIG board surface finish is an electroless nickel layer capped with a thin layer of immersion gold. Many procedures have color illustrations to help the user understand the guide.

Retrieved from ” https: Major topics include flex attachment, board-in-board, part-on-part, both lead-free and tin-lead criteria, component orientation and soldering criteria for through hole, SMT, cleaning, marking, coating and laminate requirements.

This revision includes two new SMT termination styles, as well as changes in plated-through hole fill and BGA void criteria. The inserted Amendment 1 provides more fole on the solderability of the immersion tin, using both tin-lead as well as “lead-free” solders using appropriate fluxes.

Revision F has photos and illustrations of acceptability criteria — 86 of them new or updated. Increasingly, semiconductors have been manufactured in smaller sizes.
