How are PCBs fabricated?

How are PCBs fabricated?

The manufacture of the PCBs is normally achieved using a chemical etching process. Typically the copper on the bare printed circuit boards is covered with a thin layer of photo-resist. It is then exposed to light through a photographic film or photo-mask detailing the tracks required.

What are PCBs made up of?

Printed circuit boards (PCBs) are usually a flat laminated composite made from non-conductive substrate materials with layers of copper circuitry buried internally or on the external surfaces. They can be as simple as one or two layers of copper, or in high density applications they can have fifty layers or more.

How are PCBs made in the manufacturing process?

Basic PCB manufacturing process. With the bare PCB boards chosen and available the next step is to create the required tracks on the board and remove the unwanted copper. The manufacture of the PCBs is normally achieved using a chemical etching process. The most common form of etch used with PCBs is ferric chloride.

What goes on behind the scenes at the PCB manufacturer?

While you can find information on circuit board design easily, we sought to answer the question: what goes on behind the scenes at the PCB manufacturer? Bay Area Circuits, a Silicon Valley PCB manufacturer specializing in quick turn prototype manufacturing, was kind enough to give us an inside look at the process.

How is a PCB manufactured at Bay Area circuits?

At Bay Area Circuits, a Planner will also create a set of instructions called a “process card” (or “traveler”) which will travel along with the work as it’s being completed. Additionally, a CAM Engineer will perform the design review and converts design files into the data format used for manufacturing.

What do you need to know before making a PCB?

Before PCB design, circuit designers are recommended to get a tour of a PC board shop and communicate with fabricators face to face over their PCB manufacturing demands. It helps prevent designers making any unnecessary errors from getting transmitted during the design stage.
