PCB Assembly Production

PCB Assembly Production Description:

At the stage where production PCB assembly is being planned, many other factors come into play, particularly Design-for-Test (DFT) and Design-for-Manufacturability (DFM) issues, making sure documentation is current, planning diagnostics tests and macros, determining test limitations and assuring that troubleshooting guidelines are well-documented among others.

Regarding DFM, circuit board fabrication issues include using the right size panels that will offer the highest yield. This is particularly important in projects with non-standard circuit board shapes. OEM takes the time required to assure that the right fabrication panels are used so as to minimize waste. Another important factor is the number of panels per board because it can have an effect on testing as well as on the pick and place line. Having a balanced placement of boards per panel can increase PCB assembly speed where SMT and wave solder fixtures are used to run multiple boards through each of the assembly processes.
