Purpose

This publication describes materials, methods and acceptability criteria for producing quality soldering interconnections and assemblies. It is not the intent of this document to exclude any acceptable procedure for component placement or for applying flux and solder used to make the electrical connection; however, the methods used must produce completed solder joints conforming to the acceptability requirements described in this document.

The illustrations in this document portray specific points noted in the title of each page. A brief description follows each illustration.

In the case of a discrepancy, the description or written criteria always takes precedence over the illustrations.

The visual standards in this document reflect the requirements of existing IPC and other applicable specifications. In order for the user to apply and use the content of this document, the assembly/product must comply first with other existing IPC requirements, such as IPC-SM-782, IPC-D-275 and IPC-A- 600. (¡.e. if the assembly does not comply with the design requirements of IPC-D-275 or IPC-SM-782, then the criteria can not be applied. It must be redefined between the customer and supplier.
