The IPC-9202A, Material and Process Characterization/Qualification Test Protocol that records changes in Surface Insulation Resistance (SIR) on a representative sample of a printed circuit assembly (PCA). It quantifies any deleterious effects that might arise from solder flux or other process residues left on external surfaces after soldering, which can cause unwanted electro-chemical reactions...
This document describes the design and assembly challenges and ways to address those challenges for implementing 3D component technology. Recognizing the effects of combining multiple uncased semiconductor die elements in a single-package format can impact individual component characteristics and can dictate suitable assembly methodology. The information contained in this standard focuses on...
The IPC-6903A standard provides 62 additional terms and definitions for the design and manufacture of printed electronics. The IPC-6903A standard creates a common language and understanding for the worldwide printed electronics community.
This standard prescribes the nomenclature, requirements and test methods for electronic grade solder alloys; for fluxed and non-fluxed bar, ribbon and powder solders for electronic soldering applications; and for ‘‘special’’ electronic grade solders. This is a quality control standard and is not intended to relate directly to the material’s performance in the manufacturing process. Solders for...
This specification sets requirements based on performance criteria for the use of Immersion Silver (IAg) as a surface finish for printed circuit boards. It is intended for use by chemical suppliers, printed board manufacturers, electronics manufacturing services (EMS) companies and original equipment manufacturers (OEM). IAg is a thin immersion deposit over copper. It is a multifunctional surface...
Strain gage testing allows for objective analysis of the strain and strain rate levels to which a surface mount package may be subjected to during assembly, test and operation. Excessive strain can result in various failure modes for different solder alloys, package types, surface finishes or laminate materials. This document describes specific guidelines for strain gage testing during the printed...
This document standardizes the requirements for power conversion devices (PCDs) for the computer and telecommunications industries. The phrase “power conversion devices” refers to ac to dc and dc to dc modules, converters and power supplies.
