  • Current
Published 2018-02-12 by SAE International in United States
This document defines: 1 A default method for those companies that require a pre-defined approach and 2 A protocol for those companies that wish to develop their own test methods. The default method (Section 4 of the document) is intended for use by electronic equipment manufacturers, repair facilities, or programs which, for a variety of reasons, may be unable to develop methods specific to their own products and applications. It is to 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 Pb-free solder. The default method is intended to be conservative, i.e., it is biased toward minimizing the risk to users of AHP electronic equipment. The protocol (Section 5 of the document) is intended for use by manufacturers or repair facilities which have the necessary resources to design and conduct reliability, qualification, or process development tests that are specific to their products, their operating conditions, and their applications. Users of the protocol will have the necessary knowledge, experience,…

Requirements for Using Robotic Hot Solder Dip to Replace the Finish on Electronic Piece Parts

G-24 Pb-free Risk Management Committee for ADHP
  • Aerospace Standard
  • GEIASTD0006A
  • Current
Published 2016-02-24 by SAE International in United States
This standard defines the requirements for fully replacing undesirable surface finishes using robotic hot solder dip. Requirements for qualifying and testing the refinished piece parts are also included. This standard covers the replacement of pure tin and Pb-free tin alloy finishes with SnPb finishes with the intent of subsequent assembly with SnPb solder. This dipping is different from dipping to within some distance of the body for the purposes of solderability; solder dipping for purposes other than full replacement of pure tin and other Pb-free tin alloy finishes are beyond the scope of this document. It covers process and testing requirements for robotic dipping process and does not cover semi-automatic or purely manual dipping processes. This standard does not apply to piece-part manufacturers who build piece parts with a hot solder dip finish. It applies to refinishing performed by a robotic hot solder dip service supplier or production facilities at the customer, whenever the intent of the dipping is to have full coverage and replacement of Pb-free tin. Replacement of BGA spheres or CGA columns…

Program Management/Systems Engineering Guidelines for Managing the Transition to Lead-Free Electronics

G-24 Pb-free Risk Management Committee for ADHP
  • Aerospace Standard
  • GEIAHB0005_1
  • Historical
Published 2006-06-01 by SAE International in United States
This handbook 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. Programs may inadvertently introduce Pb-free elements (including piece part finish, printed wiring board finish, or assembly solder) if careful coordination between buyer and supplier is not exercised. For example, piece part manufacturers may not always change part numbers to identify Pb-free finishes, especially if the previous tin-lead (Sn/Pb)-finished piece part has been discontinued. Detailed examination of piece parts and documents at receiving inspection while crucial, may not be sufficient to identify Pb-free piece parts. Note: Pb-free technology can impact any program regardless of whether the program itself is exempt or bound by environmental regulations. The industry conversion to Pb-free solder technology may affect an aerospace program in one or both of the following ways: If the program is required to implement Pb-free technology (contract requirement, environmental regulation, etc), then the program manager/lead systems engineer will need to assess the impact of in-house transition with respect to design (performance of…
