Here's a look at how I assemble my work, I do 99% surface mount components, usually 0402 capacitors and resistors, leadless packages and smaller BGAs. All without a scope ;).

Here's a look at my setup, it's just a simple rework station and an ESD mat.

A bare PCB, the one picture is a A04 revision.

Here is the same PCB with the ICs, USB port, and Power switch

And the same PCB with all the capacitors and resistors added.

The completed PCB with the motors and rechargeable battery

The battery and motors in their housing, and...

The completed unit!

Loading the bootloader firmware

Loading the encoder module firmware

And loading the diagnostic software! This unit is ready to go through final testing and QA!
