14 Things You Need To Know About Printed Circuit Boards

Categories Business

Do you know what a printed circuit board is? Have you ever seen one? A printed circuit board is inside a gadget or an electronic device. You won’t be able to see it unless you actually open the device.

They are an amazing part of a device. Without it, the gadget will never work. It’s like the brain of an electronic device.

Here are some things you need to know about printed circuit boards.


1. This is an obvious fact, but to those who do not have an idea what printed circuit boards need to know that boards are usually colored green. The solder mask gives it the green color. PCBs are found in different electronic devices such as radios, computers, radars, etc.
PCB2. They are designed differently, depending how they are used for. CAD or Computer Aided Design is the computer program used to design a printed circuit board. People who make a printed circuit board sometimes do not use the computer program as there are manufacturers who are giving away their PCBs for free.

3. Manufacturers need to be extra careful with the boards especially in manufacturing them. The environment needs to be clean and dust- free. A dirty environment could actually contaminate the printed circuit board.

PCB4. Manufacturers are strict when they do quality control for a printed circuit board. PCBs undergo many quality control tests before they are out in the market for sale. Some of them would even go through environmental tests to ensure that the printed board would really work. If they find just a single fault in it, they always take it out. Once quality control is done, PCBs are then tested whether they function or not.

5. The size of the printed circuit board would always depend on the size of the electronic equipment. Bigger devices contain bigger PCBs too. Small electronics have smaller PCBs.

6. Some equipment also contain layers of boards.

Complicated designs have multi-layer PCBs. Don’t get too caught up on the design on a printed circuit board. You will really be confused if you’re not too techy.

7. There are guidelines that you need to follow when creating a printed circuit board. If you’re making complicated layers, check with the manufacturers before submitting your own design. Circuit boards with complex designs usually have different guidelines.

8. Manufacturing printed circuit boards take a lot of time. If you’re thinking about making one, go for a low-cost printed circuit board.

9. Some circuit board designs are free. The only downside is you will not be able to modify it. Nope, you can’t place layers on the printed circuit board unless you ask permission from the manufacturer. To be on the safe side, always ask permission for modification if the design isn’t yours.

10. One important thing to note about printed circuit boards: complicated devices like computers have multi- layer PCBs. They will not run on a single-layered PCB.

11. A device, depending on how complicated it is, can have up to 12 PCB layers.

12. There are three types of PCBs: First would be the single- sided PCBs. Simple devices have this design. It is also easy to manufacture, and it’s not pricey. The next type is the double- sided. The design are for devices that aren’t too complex. The last type is the multi- layered PCBs. Computers usually have this design.

13. Two technologies are used in manufacturing a printed circuit board. First is the Through Hole Technology. This is the older version. The newer one is the Surface Mount Technology. Manufacturers still use both technology these days.

14. High quality electronics contain the FR4. The board becomes thicker if they use the FR4. Low-end electronics do not use this because it’s a little expensive. There are less expensive materials like phenolics that they can use, but they’re not really that durable compared to the FR4.

PCBs are an amazing invention. Without it, we won’t be able to enjoy our gadgets. While they may seem sufficient for modern-day applications though, rest assured that they’re continuously evolving.
