A PCB or printed circuit board is a plate or a board used for assembling together different elements that are essential for an electrical circuit that carries a technical and electrical connection between them.
The simplest of PCBs are those ones that contain copper tracks or any other form of interconnection between them. This type is known as the layer 1 printed circuit board or a 1layer PCB. However, the most common form of PCBs that are layer 2 PCBs. They have copper tracks on the both surfaces.
PCBs can be manufactured in eight different ways.
The tactics of Soldermask:
In order to mount the required electrical components, there must an assembly process. This process is done manually or by specially designed machines. This process requires the use of solder in order to place the components on both sides. The most common color of solder that is used for this PCBs are green.
The Process of silkscreen:
Silkscreen is a manufacturing process that prints all information on the soldermask which facilitates the conducive process of assembling, verification and repair. It requires a lot of information like the position, orientation and reference of the electronic components that are commonly used in old PC motherboard. The information can be printed on both the sides of the board.
The Process Related To Stack Up:
As you already noted that printed circuit board can be of various levels. Many times, PCBs are manufactured with EDA software and that helps building it in many layers. Like the silkscreen and the soldermask are nonconductive layers. Having both conductive and non-conductive leads to confusion. This is why CAD or computer-aided designs are taken into considerations and this is why this task is done well.
To sum up
There are many other techniques related to the manufacturing and assembling PCBs. These three are the top ones and mostly used in the interest of the business owners and their clients. Printed circuit board assembly in China brings more advantages.
However, if you are not partnering with a reliable solution provider, you may run into trouble for sure. But if you hire a good company providing PCB assembly services you can make the entire thing done.
Talk to experts in the industry and they would be able to give you the right way to get started at the right time.
Once you start you get an idea about the process to follow that strikes a balance between the two. It will help you get started and in the future will help you make the most of your money invested.
