Summary: PCBs have become an essential part of the electronic device manufacturing industry. The PCB assembly process is based on high precision manufacturing. Read the following write up to know why PCBs are so important.
The Printed Circuit Board Assembly is a method of connecting various electronic components to a circuit board in order to make a fully functional assembly. The electric signals are made to pass through the etchings in copper sheets which are laminated and acts as non conducting substrate.
The process of assembling them has to be very precise. In the event that one fails to follow any of the steps the end results can be disastrous. You will end up with faulty PCBs with two types of faults, ‘short’ or ‘open’. There are two ways of assembling these circuit boards
In the through-hole process PCB components are inserted into holes previously made on the boards.
The second process is called the surface mount process. In this process the components are placed and molded on the external surface.
Both these processes require the components be fixed mechanically and electrically on the board with the help of soldering metals. The soldering process is followed by PCB conformal coating or resin encapsulation. This step is essential because it has to work in many contaminated environments. The coating or encapsulation ensures unobstructed system performance by providing mechanical protection and electrical insulation. The ease of the coating process is an added advantage. Plus the thin coating aids the miniaturization and portability of electronic devices.
PCB’s have become more important now than ever before, because of the following fundamental properties
It lends mechanical support to the electronic devices.
It connects the components to each other internally. And enables electronics to interact with the user through input/output connections.
Aids heat transfer inside the device.
Provides electromagnetic shielding and so on.
Since the PCB plays such an important role in so many electronic devices majority of the electronic manufacturers are now incorporating them in their designs. But because of its precise nature of the assembly process it is a costly affair. It needs an entire assembly set up during the manufacturing processes. In order to surpass this step most companies are now outsourcing this step to Subcontract Electronic Manufacturing companies.
These companies specialize in manufacturing PCB assemblies. They have experienced engineers under their belt are adept in these processes. These Sub Contract PCB Assembly manufacturers not only assemble these circuit boards they can also design them as per the clients request. Apart from assembling they provide other services like testing manufactured devices and fixing faulty ones.
Hiring one of these Subcontract Electronic Manufacturing companies is quite beneficial because
It cuts down the need for setting up a PCB production line.
Helps to keep you focused on the development of the devices design without worrying about the assembly design.
You get to invest the money that you saved on other aspects of the electronic device.
Lastly these Sub Contract PCB Assembly companies have more experience in this field. They have way more technologically advanced engineers and team members.
Thus if you own a small or medium sized electronic device manufacturing companies and hope to expand your horizons go for these PCB assemblies. And don’t forget to hire a veteran contractual manufacturer.
