  • Before you layout a circuit, it’s generally a good idea to understand what is happening in your schematic.  And before you lay out a schematic, it’s generally a good idea to understand what is happening in your block diagram. In this 4 part series, we will be Read More
  • Every Electronic Design Automation (EDA) tool is a bit different.  Some have more features than others, some have different features, some offer simulation, some don’t.  But they all have a few features in common: they allow designers to capture a schematic and layout a PCB. In a schematic diagram, Read More
  • After part placement, the next step is to route traces between nets.  In previous lessons, we discussed how to choose trace and space width for your design. How are you supposed to connect intersecting wires or connect wires to nets?  An image below shows several Read More
  • Joe Selvik and Duncan Lowder of FixturFab join us to discuss custom test and programming fixtures. Whether you make 10 or 100,000 test fixtures, learn critical information for your next design. FixturFab provides modern PCBA test solutions for every stage of the hardware development lifecycle. Read More
  • New designers tend to remove a great deal of copper from their boards.  The problem with this approach is that without copper present in equal amounts on mirror-layers of the circuit board that constrain the expansion of the dielectric layers equally, the printed circuit board Read More
  • Every fabrication shop has a list of design rules that they provide to customers that detail the limitations of the manufacturing process.  The specific numbers used will depend on the fabrication shop that you use as well as whether you are using their recommended process Read More
  • Whenever you route a signal trace, you need to pay attention to the return path for that trace — return signals take the path of least impedance, not the path of least resistance. Ideally, every digital signal line and power rail will have an uninterrupted Read More
  • When your signal frequency approaches 10 GHz, copper roughness and fiberglass smoothness and quality come into play. Learn how to move beyond your fabrication houses cheapest materials into higher quality, higher speed materials with Fred Scheer from Panasonic. https://youtu.be/cd16AY1IAgs Download the presentation slides here.

  • FR-4 is commonly used to describe the dielectric material that makes up PCBs. That’s a problem since FR-4 stands for Flame Retardant level 4, and hundreds of possible laminates meet that specification “FR-4” only describes the way the material behaves when exposed to flame. Mark Read More
  • A PCB Panel can hold one or one-thousand boards. How do you design for panelization? What are mouse-bites? V-scores? What about tooling holes? Learn all of this and more with Royal Circuits’ PCB Panelization Expert, Elijah Gracia. Read More
  • To help design engineers get back to work, we are offering a rare, super-low discount on PCBs. Limited-time only. # of Layers Price Per Board Price For 5 Boards 2 Layers $30 $150 4 Layers $60 $300 6 Layers $80 $400 Details Max size 5” Read More
  • What is a Stackup? PCBs are made of alternating layers of conductors and insulators (dielectrics).  Multi-layer PCBs are either made by laminating two or more premade cores together, or by starting with a core and laminating foil on the outside to build up the outer Read More
  • In this customer grab-bag, process engineers from Royal Circuit Solutions and Advanced Assembly answer questions live. https://youtu.be/LeWcwiHxXmQ Read More
  • This webinar covers cleaning and cleanliness testing best-practices including: – Contamination failure mechanisms – Cleaning challenges and strategies to overcome them – Environmental best practices (how to solve one problem and not create another) – Choosing an appropriate cleaning method (a review of various cleaning Read More
  • Learn about material stackups and impedance control with Royal Circuits dedicated stackup engineer Teresa Jensen. This webinar covers all of the industry jargon and lets you know how conductors and dielectrics are selected for your next design. Read More
