Soldering Iron Dremel
Manufacturing circuit boards is a process that takes some time and it is not considered a "simple thing" to complete. Although, there are enthusiasts who can make their boards that are own home with the proper materials, but they often are usually never as complex as bulk manufactured people. Also, it might be pretty time intensive to hand make 20,000 PCBs. Below, I shall quickly walk you through the PCB Assembly procedure and what is included at each and every phase.
PCB Assembly, which can be also called Printed Circuit Board Assembly is once you solder components that are electronic a PCB or printed circuit board. A circuit board which includes maybe not yet been put together with the electronic components are called PCB or Printed Circuit board as soon as the boards have soldered components on it, they have been theoretically called Printed Circuit Assembly or Printed Circuit Board Assembly.

9. Finishing - the process of covering the pad areas having a slim layer of solder to get ready the board for the wave that is eventual or reflow soldering procedure that will occur at a later time after the components have been placed.
10. Silk Screening - the entire process of applying the markings for component designations and component outlines to the board. Can be put on just the top side or to both edges if components are mounted on both top and bottom edges.
11. Routing - the entire process of isolating multiple boards from a panel of identical boards; this process additionally allows cutting notches or slots into the board if required.
12. Quality Control - a inspection that is visual of panels; also can function as process of inspecting wall quality for plated through holes in multilayer boards by cross-sectioning or other techniques.
13. Electrical Testing - the entire process of checking for continuity or shorted connections on the panels by means using a voltage between different points on the board and determining in cases where a flow that is current. Depending upon the board complexity, this technique may need a especially designed test fixture and test system to incorporate because of the electric test system employed by the board manufacturer.
