PCB Bare Board Manufacturing

PCB stands for 'printed circuit board' - an essential component within almost all electronic assemblies. These are easily recognisable to most people as green boards with various markings outlined upon them.

The production of PCBs as a standalone process is surprisingly complex, but nonetheless necessary within the manufacture of a larger mechanical assembly. PCBs are often bespoke to the requirement, meaning that they will usually need to be designed according to the application. This is usually done using specialist software, before the project can move onto the production stage.

PCBs are generally made from carbon fibre board clad with copper on both sides. A chemical etching process is used to remove unwanted copper and create the required tracks - alternatively, the copper is removed using a milling machine. Once this process is complete, any holes are drilled accordingly, before a polymer known as 'solder resist' is applied to the board in areas that are not to be soldered - this is done to prevent accidental short-circuiting.

Often, PCBs are additionally screen-printed with text to aid assembly, such as highlighting the intended locations of electronic components. Some electronics companies offer PCB bare board manufacturing as part of a wider assembly service, whilst others may specialise in this process alone.

  • PCB stands for 'printed circuit board' - an essential component within almost all electronic assemblies.
  • The design of PCBs is carried out using specialist software before the project moves into production.
  • The manufacture of PCBs is a multi-step process involving chemical etching/milling, drilling and the application of a polymer known as 'solder resist' to prevent short-circuiting.
  • Additionally, PCBs may be screen-printed with text highlighting the intended location of electronic components.

What is the best method for suppliers to contact you?

We will be putting suppliers in contact with you directly so they can quote your project. Some suppliers may have questions so they can quote you correctly. Additionally, most suppliers usually like to follow up to see how they got on and all we ask is that you provide them with feedback, whether they have won the project or not. With this in mind what is the best method to reach you on (you can choose both)?
