Time Lapse of the assembly process for a 3D Printed PCB: Adding copper traces and then soldering on the components.
Actual assembly time was 1 hour
Copper is 2.75 mils thick to handle the full 24 amps the Fairchild Power N-MOSFET is rated for.
At the end of the clip the MOSFET daughter board is soldered into the 3D Printed base board ( Base board has 4 MOSFET switches and one MOSFET driver + appropriate terminal blocks )

Advantages from professional circuit board assembly
If you are wondering about accomplishing the circuit board assembly in-house at a professional level you’re shortly going to realize the original investment expenditure is very high. You must have a minimum of: one pick and place device, one stencil printing machine and one reflow oven. You may in addition want other relevant gear for inspection work and hand soldering gear. You will probably need manpower and expertise which could raise the investment cost notably. And ultimately when you think about there is little or no ROI from this sort of expense you will swiftly make a decision to use outside agencies for the circuit board assembly service. Most frequently delegating the circuit board assembly service to an outward service provider ought to be more affordable.
Then there’s the element of quality; a firm committed to circuit board assembly services will have the experience and manpower to provide great quality. They’ll also put money into their development by always having the most advanced technology to make sure the client gets all the benefits from the completely new assembly technologies. Chances are that you’ll hit a equipment related limitation doing in-house assembly if you can’t up-grade the equipment routinely, by way of example, you might end-up in a predicament where you aren’t able to efficiently assembly the most up-to-date BGA package for a brand-new processor.
Additionally, there is the facet of quality control. A great circuit board assembly factory will also have an effective tested quality control service that you could make the most of by not being required to do the quality control in-house. Sure, you might need to do an additional quality control step in-house but it is great to know at any rate the pcb’s are all doing work effectively when they depart from the assembly line.
Downsides of professional circuit board assembly
One reason you will not want to contract out the assembly of your project is to safeguard intellectual property. For everybody who is working away at some top secret project or the most current idea that will transform something, you ought to keep that as confidential as possible so in that case you could do the circuit board assembly in-house.
In addition there are cases when the turn-around time of a prototype is important so you can not afford to wait a week for your circuit board to return from a professional assembly line. If so it may make more sense to carry out the assembly in house.
Cost is likewise a pretty important reason you may possibly not wish to decide on a professional circuit board assembly factory, specifically for smaller businesses or lovers. Charges for circuit board assembly services have lessened significantly in the past few years so this is less of an issue as of late but you may not see loads of people sending their one-time hobby projects to a circuit board assembly factory.
