Are you interested in learning more about how all the electronics you use work? Most of your electronics from your phone to your TV have printed circuit board assembly that helps your electronics work. Whether you?re wanting to learn more about the pcb fabrication process and assembly or interested in trying to build your electronics with a pcb assembly quote, you need to know more about pcb assembly first.
Development of Printed Circuit Board Assembly Over the Years
Printed circuit boards have changed the industry over the years. They were first introduced around 70 years ago. By 1995, they were a $7.1 billion industry. In less than 50 years, the industry boomed that much. By 2012, they were over a $60 billion industry across the world.
Nowadays, there is a printed circuit board design software that makes things even easier. Prior to this, designers had to develop a proposed design which they then created a transparent photomask of. This was done using Mylar sheets which were much bigger than the board itself. Now, it?s much easier to do this process with the design software.
How Printed Circuit Board Assembly Works Now
Now, there are computer-aided design systems in place that help create the layout of the circuit board. This is done with a special software that helps make spaces between electrical conducting paths as small as possible. The goal is to have them as small as .04 inches when possible.
There are also different types of boards. Some are double layered while others are multilayered. Double layered boards come from two methods. The first is through-hole technology and the second is surface mount technology. For multilayer boards, you can find these in 4, 6, 8, or 10 layers. Multilayered boards are only needed for complex electronic circuits. Otherwise you can stick to single or double layered circuit boards.
In order to measure how thick a board is, you have to know something about copper. This is how designers measure a circuit board?s thickness. The goals is to keep thickness at one to two ounces of copper. Some designers instead choose to go with six ounces of thickness, instead.
In the future, the goal will be to continue to improve on circuit boards so that designers can improve our electronics. One future goal is for transistors to be miniaturized even further than they are currently. Designers hope to miniaturize them to a single nanometer. This means the thickness is equal to 10 atoms back-to-back.
If this is a career that interests you, it?s good to know that you need an engineering degree to get started learning all you can about circuit board assembly. You can work for a PCB assembly services or start your own company offering a PCB assembly quote to customers. If you prefer to pick it up as a hobby in your spare time, you can still learn about PCB assembly and potentially pick up side gigs offering a PCB assembly quote to potential customers.
Are you hoping to earn a degree in engineering to continue learning about PCB fabrication and how to offer a PCB assembly quote to those interested in buying printed circuit boards? Let us know about your experience with printed circuit boards.
