Hello, Welcome to the Altium Learning Hub

What are PCBs? PCBs are Printed Circuit Boards and they are the heart of everything electronic. The circuit board offer mechanical support and create an electrical connection between several electronic components with the aid of pads, conductive tracks, and several other features which are made from copper sheets and laminated onto non-conductive substrates. The PCB is also a housing unit on which several components (resistors, capacitors or...

I have been designing printed boards for a long time. Like most experienced PCB designers, I have my reservations about autorouters. Autorouters have a reputation for being difficult to set up and run, taking a long time to work, and giving questionable results. Often you would put your board into the router in the evening only to find the next morning that the results were not worth saving. I knew designers who would spend hours and hours...

Many years ago, I was a junior PCB learning the ropes of the trade in a large company. To help me understand the entire product production process, my boss took me on a tour of the manufacturing floor. The people that I met there were not rude per say, but I noticed a subtle attitude of, “Oh, you’re one of them” that puzzled me. The reason for their annoyance I found out later was that they would routinely suffer delays because of bad...

Sending information to other departments and personnel is a regular part of the PCB design process. For purchasing, their part of this process starts when engineering sends them a bill of materials () for a new design. At this point in the design cycle, the is a preliminary document and it is constantly changing as are added, updated, or eliminated during the design cycle. The problem for purchasing is that this constantly changing data impacts...

When starting a high speed PCB design, there’s a lot that must be considered before the design ever gets into layout. Schematic organization, board materials & layer configuration, critical component placement, and how high speed signals are to be routed are all aspects of high speed design that need to be planned for. Often there is one area that doesn’t get as much consideration as everything else, and that is the component footprint shapes...

Traces in a PCB are given two possible names based on their location in a PCB stackup: striplines and microstrips. In a PCB, a stripline and microstrip are two different transmission line structures used in a PCB layout. Microstrips and striplines also come in the coplanar and differential varieties, and all of these have certain advantages when used for high-speed or high-frequency signals. If you're looking for a thorough comparison of...

            On Track Newsletter September 2017 VOL. 1 No 6   Welcome to the September edition of Altium’s On Track Newsletter. This month PCB designer extraordinaire, Susy Webb, shares her tireless passion and continual pursuit of excellence in Design Like a Girl.
