This document describes manufacturing process simulations for use with applicable component specifications to assure that electronic components can meet expected reliability requirements after exposure to assembly factory processes. It is not intended as an assembly production specification or a stand alone qualification document. The procedure consists of a set of assembly process simulations which can be performed by either the component user or manufacturer prior to reliability testing as specified in the applicable component qualification and reliability monitoring documents. The simulations include alternative conditions depending on the component type, physical characteristics and anticipated use.

This recommended practice is intended to assist in the use of uniform methods of indicating the number of places of figures which are to be considered significant in specified limiting values, for example, specified maximum values and specified minimum values. I t s aim is to outline methods which should aid in clarifying limiting values with which observed values or calculated values obtained from tests are compared in determining conformance with specifications.

Industrial Gas Test (Battelle Method), Connectors

IPC TM-650 3.11-1975 连接器热震 修订版A 1975年7月

This manual is a road map for current and developing cleaning issues, rather than to function as a highly detailed document for all areas touched on. in areas of cleaning where recent detailed IPC manuals already exist, the relevant sections in IPC-CH-65A will contain only sufficient information to make the reader reasonably knowledgeable. This guideline manual will refer the reader to appropriate existing IPC documents (where they exist) for in-depth information on the particular subject. An example of such a reference IPC manual is IPC-AC-62, Aqueous Cleaning Handbook It is only where existing IPC documents are not available that IPC-CH-65A will expand information beyond the basics in order to cover what is currently known about the subject. A benefit of this approach is that the manual does not become unwieldy and tends to foster a user-friendly environment.
