Whenever a computer or a variety of other electronic devices is used, a PCB (printed circuit board) is engaged. PCBs were first introduced in the 1940s, but in 1995, just a little over 50 years after they were first introduced, they became an over seven billion dollar industry for the first time. With the tech boom of the modern era, the industry is now worth over $60 billion around the world. And, as time has passed, there’s been further innovation and streamlining in terms of the different kinds of PCB’s and how they’re assembled and manufactured. Manufacturers are always looking to cut costs where they can without (hopefully) sacrificing the quality, which can often lead to upset customers and a decline in sales. So how can costs be cut? What needs to go into the assembly and manufacturing of PCB’s?
