Why Printed Circuit Boards Remain in High Demand

 · The board’s design is dependent on the requirement of the electric circuit. A PCB is normally used in all electrical and electronics equipment and the reason why it has remained popular. The global economy is drastically experiencing broad technology developments, which are increasing the demand for PCBs.

What are some alternatives to circuit boards for

A computer circuit board is used to connect the electronic components and circuits inside of a computer. Computer circuit boards are composed of laminates, copper clad laminates, and copper foil.

Waste printed circuit board recycling techniques and

In this process, copper migrated to the cathode compartment and deposited on the cathode, whereas lead moved toward either anode or cathode and little was deposited on the cathode. This allowed the efficient separation of the metals from waste printed circuit boards together with the degradation of brominated compounds.

How to Properly Dispose of Old or Unwanted Electronics

 · Many of these metals comprise circuit boards and electrical parts such as computer chips, monitors, and wiring. Many electronics also include flame-retardant chemicals that might pose potential health risks when exposed. When these elements are safely encased in our computers and devices, e-waste dangers aren't problematic.

High techWikipedia

High technology, or high tech (sometimes also called frontier technology or frontier tech), is technology that is at the cutting edge: the most advanced technology available. The opposite of high tech is low technology, referring to simple, often traditional or mechanical technology; for example, a slide rule is a low-tech calculating device.

Cleaning Up Electronic Waste (E-Waste) | International

Managing the e-waste created by an increasing amount of computer and telecommunication equipment is important to the Ethiopian government, and many international partners have worked in Ethiopia to help address this concern. In 2010, EPA provided funds to the United Nations University (UNU) to assess e-waste in Ethiopia.
