Printed Circuit Boards should be manufactured and produced in a clean environment. This is to avoid air contamination with the raw materials etched to the Printed Circuit Boards. Each of the companies and manufacturers for the Printed Circuit Boards have their own kind and way of proprietary processes. You can check and get more details from http://www.nemco.co.uk for its exclusive way of manufacturing Printed Circuit Boards.
Producing and Creating the Substrate
First, what is a substrate? A substrate is the base of the board or the very most seed of the circuit board. A glass fiber is needed to feed a process where it is being sprayed and dipped with epoxy resin. After which, the impregnated glass fiber will be put through a rollers to design it to its designed thinness or thickness and to remove extra and excess epoxy resin.
Then, the impregnated glass fiber will then be put into an oven where a semi-cured is done. After the oven, the product will be cut into large panels. Then the copper sheets are being applied to the panels with different number of layers with they are being pressed with a temperature of around 340 Fahrenheit for like an hour or more thus creating and curing epoxy resins and binds the copper sheets and foils tightly to the surface of the substrate material.
The Holes Will be Drilled
The substrate or circuit boards are now large enough to make enough space for a single printed circuit board. These are stacked up on top of each other and are clipped to keep them from moving while the drilling process is going on; they will be drilled according to the designed and planned circuit board.
Each of the holes are designed to function a and provide a conductive circuit of the printed circuit boards and from one side of the board to the other side of the board through the copper sheets.
Making the Printed Circuit Board Pattern on the Substrate Material
There are two ways in manufacturing and creating the Printed Circuit Board. The first kind or way is the additive process. In this process of creating the Printed Circuit Board is that the copper sheet is plated or is being added to the substrate in the planned and desired pattern leaving the rest of the surface and spaces not plated. The second way of creating the PCB pattern on the substrate surface is the subtractive process. In this process, the substrate is being plated first and the areas that are not being plated are being etched and subtracted away.
Mounting All the Components
Each of the printed circuit boards pass through several machines which place each of the raw materials and electronic components in their desired and proper location and placement on the substrate or board. With the specialized and high quality computer operated systems, the Printed Circuit Board is manufactured and being produced with perfection even to the smallest details.
