What Is Solder Mask Expansion and Which Value Should You Use? The solder stop mask layer caps off the PCB and provides a protective film over copper on the surface layers. Solder mask needs to be pulled back from landing pads on the surface layer so that you have a surface where components can be mounted and soldered. This removal of the solder mask from a pad on the top layer should extend some distance around the edge of the pad, creating either NSMD or SMD pads for your components. How far back should Read Article 30:00 Routing Fundamentals & Techniques When you’re ready to start using a new design tool, you just want to dive in and get going.

Read Article Harness mmWave Routing with a Mode-Selective Transmission Line High frequency and data rate channels can be routed as a mode-selective transmission line. Here’s when you should consider this routing technique. Read Article Using the Sun to Keep Your Clunker Happy A lot of folks have transitioned to working from home either part time or completely which means they sometimes leave their automobiles in the driveway for days or weeks at a time. I, for one, am definitely in this camp. I could easily go for weeks without starting my clunker which means, very frequently, my car battery will die. We usually combat this problem by periodically turning on our cars and drive around the block a few times. At the best Read Article PCB Motor Robots Creation with Carl Bugeja Carl Bugeja, a well-known Youtube Creator, talks about his experience designing electronics and his fascination with inventing new things. Watch now or listen on the go. Carl will also share some exciting robotics projects he is currently working on. Read Article Thermal Management in PCB Today Clearing up the confusion about the IPC 2152 with Mike Jouppi, the “Thermal Man''. Watch this episode and be enlightened about thermal management on PCB, which will be very useful to apply to your next PCB design project. Read Article Parasitic Extraction with an Electromagnetic Solver in PCB Routing Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms. There are many 3rd party applications that can be Read Article 34:28 How Project Templates can Improve Your Design Flow With each use of Altium Designer, each of us develops a certain approach to creating and working with our PCB Watch Video Part 4: Creating Fabrication and Assembly Drawings In Altium Designer Draftsman is a sophisticated yet easy to use drawing tool that is integrated within Altium Designer, for the creation of fabrication and assembly drawings.
