SDG #187 All about PCBWay's Turnkey Assembly Service

Turnkey assembly is the step most hobbyists hesitate over: handing off not just the bare PCB but the parts sourcing and placement too. 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 here is in the detail around file preparation. Getting 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 line up with the placement file, the engineering review turns into a back-and-forth that costs days. The video also covers the choice between consigned parts and letting the assembler buy everything, the setup and stencil charges that apply to short runs, and how minimum order quantities affect the maths 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 if you are weighing assembly against hand-populating a panel yourself, because it shows what level of finish to expect rather than what is promised.

The takeaway for anyone considering a first assembled order: the cost is often lower than expected once you value your own soldering time, but the quality of your documentation largely determines whether the run goes smoothly and whether the quoted lead time holds.
