6 Amazing PCB Fabrication Process

Nowadays, almost every gadget functions with the help of printed circuit boards (PCBs). The boards are needed to be contrived by the company having the most know-how in this field. There are multiple steps in the total procedure of fabricating a PCB, and any error in the intermediate steps can be disastrous for the final product or the overall manufacturing procedure. If the fabrication process is performed by a firm with proven expertise, the likelihood of developing high-quality PCB increases by many folds.

What is PCB fabrication?

The instruments are made of with printed circuit boards in recent times where the diverse electrical and electronic constituents are organized and secured so that all the necessary electronic functions can be fulfilled. However, to achieve the most potent effect, a PCB fabrication process has to ensure the proper electrical conductivity and mechanical support to the electronic or electrical modules imprinted on the conductive paths on the surface of the PCB. It is the most useful decision to hire the most experienced company for the highest quality PCB products.

The PCB manufacture: a short know-how

Any device that needs any sort of computation for it to function will probably have a PCB inside it. The simplest instruments of today, like a digital watch, are run by the PCB. There are many steps in manufacturing a PCB and consulting with or involving a professional company like Greatpcb SMT limited will ensure an error-free PCB fabrication process. Their fundamental steps you should be aware of are given in short below;

1)      Design and printing

The PCBs are firstly designed and printed with the help of software that also specifies the number of components, the path of the relays, and the type of modules for the fabrication process. The most experienced company will use software that can provide the production team with all the relevant data.

2)      Inner layer treatment

After the design has been approved, the inner layers of the PCB are treated with the necessary reagents to laminate and then a UV exposure is performed to harden the cover material.

3)      Multilayer lamination and pressing

Thereafter, the board is developed, etched and an AOI inspection is performed. Upon the passing of the inspection, it is laminated by copper foil and pressed to give the desired tracts.

4)      Drilling and pattern plaiting

The board is drilled, de-smeared and copper-plated with the help of an electrolysis machine that coats the metal into the surface of the PCB. Thereafter, the plate is given an exposure, laminated and the pattern of the schematic is plated onto the PCB.

5)      Solder masking

The board is then coated with a liquid photo imaging solder mask, recoated with a component denoting silkscreen and further sent for a computerized inspection.

6)      CNC routing

Lastly, the board is applied with immersion gold and a final CNC routing procedure is performed.

Concluding remarks

The use of the best PCB produced by the most proficient company will be always the most appropriate option for the customer firm dealing in electronic fixtures. Contact with the most experienced company like Greatpcb SMT limited for all your PCB manufacturing issues.
