IPC D-279:1996

Establishes design concepts, guidelines and procedures for reliable printed wiring assemblies. Focuses on SMT or mixed technology PWAs, specifically addressing the interconnect structure and the solder joint itself. Discusses substrates, components, attachment materials, costings and assembly processes and testing considerations. In addition, this document contains detailed appendices covering: solder attachments; plated-through via structures; insulation resistance; thermal considerations; environmental stresses; coefficient of thermal expansion; electrostatic discharge; solvents; testability; corrosion aerospace and high altitude concerns.
