39、611921:2003 WORKMANSHIP REQUIREMENTS FOR SOLDERED ELECTRONIC ASSEMBLIES Part 1: General 1 Scope and object This part of IEC 61192 specifies general requirements for workmanship in soldered electronic assemblies on printed boards and on similar laminates attached to the surface(s) of organic substrat

40、es. This standard does not include hybrid circuits in which the conductor metallization is deposited directly on a ceramic substrate or onto a ceramic-coated metal substrate. It includes multichip modules assembled on organic substrates but excludes them when they are assembled on inorganic substrat

41、e surfaces such as ceramic or silicon. The purpose of this standards is: a) to define requirements and guidelines for good workmanship and practice in the preparation, soldering, inspection and testing of electronic and electrical assemblies; b) to enable achievement of high yields and high product

42、quality through process control in production: c) to enable the suppliers and users of electronic assemblies to specify good manufacturing practice as part of a contract. 2 Normative references The following referenced documents are indispensable for the application of this document.
