Best PCB design software

printed circuit boards (PCBs) are used in all but the simplest electronic products. They are more costly to design but they allow automated manufacturing and assembly. As a result, products become faster and cheaper to manufacture, while being more reliable. Here are a few of the best PCB design software programs available for personal use. They aren’t listed in any specific order, the project’s requirements will determine which one will be better suited to that project. ZenitPCB A great to...

How to Deal With PCBs When Recycling Electronics

Printed circuit boards (PCBs) are integral components of many electronic devices, typically composed of a dry film laminated onto copper foil with a fiberglass base. Manufacturers usually install them as plug in parts, so when they burn out or become obsolete, you can replace them. Because they contain potentially harmful chemicals and metals, the EPA classifies them as toxic or "special" waste. Here's how to dispose of them safely. Instructions 1 Recycle PCBs by finding a local facility that ...

How to Make Your Own Circuit Board Devices

printed circuit boards (PCBs) allow engineers to create permanent electrical circuits that consist of multiple components and are capable of complex functions. Each board starts as a thin sheet of fiberglass with one side coated in a layer of copper foil. The surface is then etched with a strong acid, leaving only the circuit paths and terminals. Once holes for the circuit components are drilled into the board, a technician carefully solders each into place. Most manufacturers use expensive, aut...

DIY Circuit Boards

Many tools are available for hobbyists who want to make their own printed circuit boards (PCBs). One of the simplest methods uses a laser printer. You create the PCB pattern using software, print it on the laser printer and transfer it to the circuit board. If you don’t want to get your hands dirty, you can send the pattern to a company that can make the board for you. MaterialsTo make your own printed circuits at home, first pick up a few items at a store that sells electronics parts for hobb...

How to Balance PCB Copper

Printed circuit boards (PCBs) consist of insulating substrates upon which tiny copper tracks and electrical components are placed. The thickness value of a copper track is often expressed in copper weight. A copper weight of one-quarter oz. corresponds to a thickness of .00036 inch. Modern-day PCBs are often double-sided; when this is the case, similar thicknesses and amounts of copper should be placed on each side. This process is known as copper weight balancing. Instructions 1 Create a new...

How to Reduce Noise in a PCB Board

Electronic noise in printed circuit boards (PCBs) can adversely affect the operation of the circuit. This is especially true for circuits that operate at frequencies in MHz range and higher. This is because at high frequencies, electromagnetic waves that are created around the traces and inside components can be picked up by other traces and components. This may result in degradation of performance through changes induced in the shapes of current and voltage pulses. Reducing noise and its advers...

Circuit Board Infrared Inspection Techniques

Infrared inspection of printed circuit boards (PCBs) uses heat that is emitted. This requires the presence of some current. Infrared inspection can provide information not available from optical inspections due to variations of heat emitted in different parts of the PCB. The circuit boards can be compared to known standards. Image subtraction using computer software is another technique for infrared inspection. Temperature ProfilesFlaws in printed circuit boards can cause variations in tempera...

Common Signal Integrity Issues in a PCB Layout

Electrical circuits for equipment such as televisions and cell phones contain printed circuit boards (PCBs). A typical PCB contains a large number of electronic components, such as resistors and electronic chips. These components are connected through copper traces on the board. Electrical currents, or signals, pass between the components through these traces. The quality of these currents or signals is often termed "signal integrity." Various factors can affect signal integrity. Signal Reflec...
