| Hi, | | For hand placement you should see about 150-200 ppm of errors (solder, placement, values etc) on a board populated of types such as 1206, 0805, SOT, Tantalum etc. . As for solely wrong components (component at wrong location) you can usual

Clarissa, Dave had good suggestions. We load several boards manual at this time. We set our components up in clearly marked bins. The documentation includes a chart with the part number, bin number, reference designator and color code for the par

ProcEng1 made a super important point. The packaging needs to be able to survive the temps needed to reflow the paste. There are a number of jobs we have that we either hand or selective solder the connectors after the surface mount is done for that
