WG 1 - TC 107/WG 1

IEC TS 62647-4:2018(E) defines the requirements for replacing solder balls on ball grid array (BGA) component packages in the context of an electronic components management plan (ECMP) for aerospace, defence and high reliability products. The intent of this document is to provide re-balling companies (hereinafter referred to as the re-balling provider) with the administrative and technical requirements to be incorporated within existing processes or for establishing, implementing and maintaining a new set of processes or the creation of a stand-alone re-balling process.

IEC TS 62647-3:2014(E) defines for circuit card assemblies a default method for those companies that require a pre-defined approach, and a protocol for those companies that wish to develop their own test methods. The intent of this document is to aid avionics/defence suppliers in satisfying the reliability and/or performance requirements of IEC/TS 62647-1 as well as support the expectations in IEC/TS 62647-21. The default method is intended for use by electronic equipment manufacturers, repair facilities, or programs that may be unable to develop methods specific to their own products and applications. It should be used when little or no other information is available to define, conduct, and interpret results from reliability, qualification, or other tests for electronic equipment containing lead-free (Pb-free) solder. The default method is intended to be conservative, i.e., it is biased toward minimizing the risk to users of avionics electronic equipment.

IEC/TS 62647-23:2013(E) provides technical background, procurement guidance, engineering procedures, and guidelines to assist organizations reworking/repairing aerospace and high performance electronic systems, whether they were assembled or previously reworked/repaired using traditional alloys such as Sn-Pb or Pb-free alloys, or a combination of both solders and surface finishes. This document contains a review of known impacts and issues, processes for rework/repair, focused to provide the technical structure to allow the repair technician to execute the task. This document focuses on the removal and replacement of piece parts. The information contained within this document is based on the current knowledge of the industry at the time of publication.

IEC/TS 62647-22:2013(E) is intended for use as technical guidance by aerospace, defence, and high performance (ADHP) electronic applications and systems suppliers, e.g., original equipment manufacturers (OEMs) and system maintenance facilities, in developing and implementing designs and processes to ensure the continued performance, quality, reliability, safety, airworthiness, configuration control, affordability, maintainability, and supportability of high performance aerospace systems both during and after the transition to Pb-free electronics. The guidelines may be used by the OEMs and maintenance facilities to implement the methodologies they use to ensure the performance, reliability, airworthiness, safety, and certifiability of their products, in accordance with IEC/TS 62647-1:2012. This document also contains lessons learned from previous experience with Pb-free aerospace electronic systems.

IEC/TS 62647-21:2013(E) is designed to assist program management and/or systems engineering management in managing the transition to lead-free electronics to assure product reliability and performance. The basic principles delineated in this document can be used for program management and/or systems engineering management of any aerospace and/or high performance program. The annexes in the document describe tools that can be used in conjunction with this document. This document is designed to assist a program in assuring the performance, reliability, airworthiness, safety, and certifiability of product(s), in accordance with IEC/TS 62647-1.

IEC/TS 62647-2:2012(E) establishes processes for documenting the mitigating steps taken to reduce the harmful effects of Pb-free tin in electronic systems. This Technical Specification is applicable to aerospace, defence, and high performance (ADHP) electronic applications which procure equipment that may contain Pb-free tin finishes. It may be used by other high-performance and high-reliability industries, at their discretion.

IEC/TS 62647-1:2012(E) defines the objectives of, and requirements for, documenting processes that assure customers and regulatory agencies that aerospace and defence electronic systems containing Pb-free solder, piece parts, and PWBs will satisfy the applicable requirements for performance, reliability, airworthiness, safety, and certifiability throughout the specified life of performance. Keywords: avionics, lead-free solder

IEC/PAS 62647-21:2011(E) is designed to assist program management and/or systems engineering management in managing the transition to lead-free (Pb-free) electronics to assure product reliability and performance.
This publication is to be read in conjunction with IEC/PAS 62647-1:2011 and IEC/PAS 62647-2:2011.

IEC/PAS 62647-22:2011(E) is intended for use as technical guidance by Aerospace system Suppliers, e.g., Aerospace system Original Equipment Manufacturers and Aerospace system maintenance facilities, in developing and implementing designs and processes to ensure the continued performance, quality, reliability, safety, airworthiness, configuration control, affordability, maintainability, and supportability of high performance aerospace systems (subsequently referred to as AHP) both during and after the transition to Pb-Free electronics.

IEC/PAS 62647-23:2011(E) provides technical background, procurement guidance, engineering procedures, and guidelines to assist organizations reworking/repairing aerospace and high performance electronic systems, whether they were assembled or previously reworked/repaired using traditional alloys such as SnPb or Pb-free alloys, or a combination of both solders and surface finishes.

IEC/PAS 62647-3:2011(E) addresses the evaluation of failure mechanisms, thru performance testing, expected in electronic products containing lead-free (Pb-free) solder.

IEC/PAS 62647-1:2011(E) defines the objectives of, and requirements for, documenting processes that assure customers and regulatory agencies that aerospace and high performance electronic systems containing Pb-free solder, piece parts, and boards will satisfy the applicable requirements for performance, reliability, airworthiness, safety, and certifiability throughout the specified life of performance. The goal is to communicate requirements for a Lead-free Control Plan (LFCP) and to assist suppliers in the development of their own plans.
