Hey, nice video! I actually am an electrical engineer, and you pretty much got everything about as good as you can doing it by hand. If you have the fab or assembly house do it they are going to have everything automated, the paste will be applied to the stencil in a machine, a machine will place the parts, and they will have a long oven with a conveyor belt through that actually ramps the temp to a specific profile through. One thing to keep in mind about getting springing to get it assembled is you can have them do only some of the parts (for example everything but the hot swaps). I commonly do this for prototyping, I’ll have the assembly house do all the SMT parts except maybe a few I want to play with the values or if there’s only one or two through hole parts since that’s a separate machine.
