What are Circuit Boards Made Of?
If you've ever looked at a circuit board, you probably noticed that it was green and lots of little gizmos all over it. Those gizmos are switches, transistors, capacitors and resistors. They all have different jobs -- for a more detailed and scientific explanation, you'll have to talk to an electrical engineer. You'll also notice lines that connect the gizmos and little holes which are called vias. (Again, for a more scientific explanation, consult your local, friendly engineer!)How are Circuit Boards Made?
The process of manufacturing a circuit board involves several steps, including:- Silk screen printing
- Photoengraving
- PCB milling
- Laser resist ablation
Circuit Board Manufacturers
SAE Circuits is a Colorado-based circuit board manufacturer. The company has more than 35 years of experience and offers fast turn around times; their standard turnaround time is 10 days, but for customers who need orders filled fast, SAE offers 2-, 3- and 4- day turnarounds.Photo credit: docoverachiever / Foter / CC BY
