Here is the playbook to avoid that. deal · sample · order · inspect · ship Step 0: do not start on Alibaba Counter-intuitive but true. Start on 1688.com (the domestic-facing version, prices in RMB, less padded for Western buyers), LCSC (for components), and Made-in-China.com (better verification of trade licences).

Commercial bench supplies start at $80 and feel like 2003. This build gives you a serial console, programmable presets, USB-C input, and a part you can read every line of. A...

Cost: $700. Time: a long weekend plus a week of fiddling. PCB on bed 0402 R 0402 C 0805 R SOIC SOT-23 QFN Why build instead of buy Commercial desktop pick-and-places start at $4,500 (LumenPnP, with feeders) and the entry-level pro models from China land near $9,000.
