Today's PCB Assembly Processes
The process of assembling and manufacturing a printed circuit board can be broken down into five stages: pasting, pick and place, "cooking," inspection and testing. After a manufacturer has all they will need, they usually follow this overview or processes.
Begin by applying solder paste to the empty board. There are a few ways to handle this but it is common to use a solder screen. The screen is created using the files provided by the designer and contains holes delineating the location of each component on the PCB. Paste is then applied through these holes directly on to the surface in a precise manner, which ensures that when the solder pads of each component are added later in the process, there will be enough paste on that spot to bond to the pad and temporarily attach the component to the board.

The next stage of the PCB assembly process involves the actual placement of the components onto the board through what is known as "pick and place." In this procedure, a machine, programmed with the PCB design specifications, picks each component from a dispenser of some type and places it in the correct location on the board. Solder paste will temporarily adhere all components to the PCB until they are permanently adhered to the board in the following step.
After all of the components have been set in paste, it is time to "cook" the PCB. This involves putting the PCB through an oven, heating the board just enough to permanently attach the components while not causing any damage. For components that are too fragile to be soldered with this process, there are other ways to do it.
Once this is done, the PCB has to go through an inspection process to be sure it is working to specifications. Commonly, this is done by putting the board in a machine that checks all connections and confirms locations for every component. A few of these machines have the ability to determine any errors caused by wrong components chosen by the pick and place machine.

The last step in the PCB assembly process is the board testing. This is sometimes called the burn-in process, in which the PCB is inserted into the device for which it was created, such as a computer, and the computer is run for a certain amount of time to determine whether the board is fully functional.
