• The Top 10 D-Sub Connectors

    March 20, 2019 The SnapEDA Team

    D-Sub connectors, also known as D-subminiature or DB connectors, are electrical connectors commonly used in communications. They consist of two or more parallel rows of pins (in male connectors) or holes (in female connectors). The name D-Sub comes from their characteristic D-shaped metal shield, which has two important functions: it provides mechanical strength and ensures…

    The top 10 linear voltage regulators

    March 3, 2019 Faust

    In electronics, linear voltage regulators are commonly used to stabilize voltages. Regardless of the input voltages or load conditions, they will provide fixed output voltages, thus protecting devices from fluctuating outputs, which can cause inefficient performance or even damage. When designing a power supply for an application that requires a small difference between its input…

  • How to make global fiducials in Allegro

    November 28, 2018 The SnapEDA Team

    Fiducial reference points are necessary in a circuit board if you are going to assemble your PCB using automated pick and place machines. Automated assembly machines require incredible precision to accurately place a 0201 size resistor or a 2mm x 2mm chip-scale micro BGA. A fiducial is the reference point on the PCB for assembly…

  • The top 10 USB connectors

    October 11, 2018 Faust

    Two decades ago, parallel and serial ports were the dominant interfaces for connectivity and communication between computers and their peripheral devices. Today, USB connectors have largely replaced them, becoming so ubiquitous that they’re now the default interface of choice for most electronic devices – even supplying power. The first integrated circuits supporting USB were produced by Intel…

  • The top 10 AC-DC converters

    August 16, 2018 Elizabeth

    As a follow-up to our post on the Top 10 DC-DC Converters downloaded by the SnapEDA community, we thought it was about time to cover the top 10 AC/DC converters! Converting alternating current (AC) into direct current (DC) is one of the most common power electronics applications since electricity is transmitted as AC, yet electronics generally…

  • Tutorial: Removing excess solder mask and solder paste added during import to Altium

    July 4, 2018 The SnapEDA Team

    When importing footprints downloaded from SnapEDA into Altium, the importer will automatically add solder paste and solder mask anywhere there is a copper pad. Most of the time, a 1:1 ratio between the copper pad and these other layers is ideal (as per IPC standards), however, there are times when you’ll want to remove the…
