The various stages in PCB manufacturing and assembly include adding solder paste to the board, picking and place of the components, soldering, inspection, and testing

2. • Within a printed circuit board electronics assembly/production or
manufacturing process there are a number of individual stages.
However, it is necessary for them all to work together to form an
integrated overall process.
• Each stage of assembly and production must be compatible with the
next, and there must be feedback from the output to the input to
ensure that the highest quality is maintained. In this way, any
problems are detected quickly and the process can be adjusted
accordingly.

3. PCB assembly process overview
• The various stages in PCB manufacturing and assembly include adding
solder paste to the board, picking and place of the components,
soldering, inspection, and testing.
• All these processes are required and need to be monitored to ensure
that product of the highest quality is produced. The PCB assembly
process described below assumes that surface mount components
are being used as virtually all PCB assembly these days uses surface
mount technology.

4. • Solder paste
• Pick and place
• Soldering
• Inspection
• Test
• Feedback

5. • The PCB assembly process for the manufacture of loaded printed circuit
boards has been considerably simplified in this overview. The PCB assembly
and production processes are generally optimized to ensure very low levels
of defects, and in this way produce the highest quality product.
• In view of the number of components and solder joints in today’s products
and the very high demands placed on quality, the operation of this process
is critical to the success of the products that are manufactured.
