The idea is to ensure that the registration holes are accurately punctured. The optical inspection has to do with the alignment of the inner layers to the outer layers. This is an important step to be taken to ensure that the board doesn’t suffer defects later on.

Inner Layers’ Printing: the inner layer of the PCB will now be printed or have the mapped-out figure of the copper path unto the copper foil.For this process, a set of steps, including the making of “photo films” of the PCB, and the punching of “registration holes” through the films as a way of perfecting the alignment of the films. Circuit Board Printing: this has to do with the transfer or transcribing of the PCB (schematic) design onto the bare board – the physical structure of the circuit board.Here are some of the things you need to know about this stage of PCB electronics manufacturing: Circuit Board FabricationĪ lot of steps go into fabricating the board ahead of the component placement ( assembly). The reason for doing this is to inform the designer of the design expectations, as well as the PCB schematic design tool/software used for the design. You must also note that there might be issues arising from the schematics and it often happens when you don’t communicate with the designer ahead of time. It is after the design has been made that you can contact a PCB manufacturing company to act upon it and start designing.

It is expedient to mention that the schematic design needs to be done with the best tools, such as Eagle, Altium Designer, KiCAD, OrCAD and Pads. The creation of the schematic design entails the production of the early-stage design for the PCB, which would serve as a guide for the next stages of production. However, we have listed and explained some of the most important processes below: 1. It could range from 10 and 20, depending on what you want to achieve. A lot of processes go into the production of circuit boards.
