PCB assembly a very common term that most of us listen today; especially those people who are surrounded by electronic equipment and products. However, still there are few others who are not aware of it. So for them this article would help enlighten few facts about it:
Basically, PCB comprise of various components that are put together to enable the functioning of device. However, the whole process is quite complicated and long one which is needed to be carried out carefully by the manufacturing company. Various multi-stages are carried during the PCB assembly service that includes placing of components of board, soldering them, inspect and lastly test them for working.
The foremost and basic step that is followed by the manufacturer company is ordering of silicon and other semiconductors, further which are then transformed into electronic chips. These chips are then integrated onto a printed circuit board for its working or operation.
Now let’s have a detailed look at the different processes carried under PCB Assembly Services:
Solder Paste Printing: Once the chips are prepared they are needed to be pasted on the board, during the soldering method. Basically, during this process, binding of material is done on the board.
SMT pick and place assembly: On each assembly line, chips are placed appropriately or accurately on their designated places. This is done in order to have proper functioning of device.
Reflow/Through-hole curing: So as to bind the chips properly on the board, hole curing method is performed after soldering is done. This helps to bind the chips more firmly on the board.
Conformal Coating: After the chips are soldered and placed properly, boards are covered with a protective layer coating so that they are not affected by the harmful materials or other things. Usually, conformal selective coating is done by the machines that provides protective layer to the board.
AOI and AXI: In order to get assured that no mistakes are there on the board, inspection process is also carried out during the assembly process. This method is particularly known as Automatic Optical Inspection and Automated X-ray Inspection. After soldering and pasting is done, this method is vital to perform and therefore, PCB manufacturers never miss out to leave this process of inspection.
Reworking: During the inspection, if any defect is detected then that is corrected before the board is sent out for construction. During the reworking process, board is heated, chips are removed and replacement is made with the right chips or semiconductors. Once the chips are soldered then again the inspection process is carried out in order to ensure that now the replaced board is working properly.

Fabrication of printed circuited board and its assembling is a very cumbersome and challenging task. It is generally outsourced by business to the assembly service providers. So make sure to find out the most reliable company for PCB Assembly Manufacturing .
