Component Layout in Placement Processes
Positioning CSPs and noise-sensitive devices are two of a host of considerations.
Effective, accurate component placement takes into account the best practices of design and assembly, both of them inextricably intertwined. The layout engineer must take special care to correctly place components on the board, since this has a direct bearing on assembly and testability.
Also, with the evolution of various technologies, assembly takes on newer meanings, dimensions, and demands. In particular, use of fine-pitch BGAs is escalating, challenging current assembly practices and procedures. In these situations, PCB design and assembly know-how and experience are the linchpins for effective placement.
