The manufacturing of Printed Circuit Board (PCB)
The manufacturing of Printed Circuit Board (PCB) starts off by the Etching Process. In this process copper layers are bonded on a non-conductive substrate. This is usually done with the solution of Ferric Chloride or Hydrochloric acid, since they are easily available and cheap. Other methods are also rarely use. We manufacture Printed Circuit Board Layout Services Canada.

The second important step is to drill the holes where components are to be attached. In the modernized system, it is done by Laser or CNC drills. In the old times, it had to be done with the manual drilling. But for a complex Printed Circuit Board Design, it normally has more than 10,000 drill holes. Therefore; you can imagine how long it will take to drill manually.
In the third and a much simple step, the outer layer of the Printed Circuit Board has copper connection where the components are installed. In order to make this layer solder able, it is covered with some good conductors like gold, tin or nickel.
Similarly in the fourth step we got to do the opposite procedure. The reverse to the solder able layer has to make the non-solder able. For this particular reason, some polymers are to be used to make sure the connections can’t be touched or kept in contact.

The products are now tested using computer applications to check if certain voltages are appeared at the correct point. Some of these famous methods to do so are; Bed of Nails Test, Rigid Needle Adapter and CT Scanning etc.
The final stage comes if the testing is complete and fine, and that is the assembling of the components on a Circuit Board. This can be done by Through-Hole Construction or Surface-Mount Construction. It is attached with the system both mechanically and electrically with the help of some molten metal material.
