SDG #187 All about PCBWay's Turnkey Assembly Service

Turnkey assembly is the step most hobbyists hesitate over: handing off not only the bare PCB but the parts sourcing and placement as well. This walkthrough follows a real order of small driver boards through PCBWay’s assembly service, from the initial quote through to inspecting the populated boards under the microscope.

The practical value is in the detail around file preparation. A clean set of production files matters more than the price per board: Gerbers plus a centroid or pick and place file with consistent component references, and a BOM that leaves no ambiguity about which package or tolerance is acceptable. Where a part cannot be sourced, or where the designator numbering in the BOM does not match the placement file, the engineering review becomes an exchange that costs days. The video also covers the choice between consigned parts and allowing the assembler to buy everything, the setup and stencil charges that apply to short runs, and how minimum order quantities affect the arithmetic on a small batch.

On the results side, the finished boards are checked for solder joint quality, part orientation and polarity on the small passives and ICs, and general cleanliness after reflow. That inspection is the part worth watching for anyone weighing assembly against hand populating a panel, because it shows what level of finish to expect rather than what is promised.

The conclusion for anyone considering a first assembled order is that the cost is often lower than expected once the value of one’s own soldering time is counted, but the quality of the documentation largely determines whether the run goes smoothly and whether the quoted lead time holds.
