Abstract:

The approach presented in this paper aims toward resolving producibility problems, in the design stage of an electronic circuit assembly. A brief discussion of the three main assembly processes - component placement, soldering and inspection - is followed by an investigation of the design parameters that affect these processes. A methodology for assigning producibility codes for components, with respect to their location and orientation on the board, is devised for enhanced soldering and inspection. Assembly process plans are recommended as a function of the component package styles and board configuration. Finally, a flowchart is presented for placement, utilizing the producibility codes, component area constraints and assembly process plans.

Keywords: Producibility, solderability, inspectability
