Surface mount connectors are lighter and are suitable for low-power connections when onboard grounding schemes are adjacent to routed nets. These direct paths keep noise away from critical signals. Noise from IO connections can be directed to ground planes which create pathways to the case part. Grounding pins that travel through the PCB can be tied off to any, or all, of the ground planes in the PCB layout. Through-hole connections benefit from grounding shields and pins. Considering types of IO utilized by the circuits on your PCB drives selection. There are many connectors for IO interface to join PCB connector signals to other devices. Connectors Benefit from Compatible ECAD/MCAD Tools USB is a universal protocol for connecting devices and there are new developmentsĬompare USB Type-C: A New Frontier for Power and Data Transmissionĭefining IO for your design informs selection of components to put into your 3D model.Memory PCB design pads plug into motherboard socketsĬonsider protocol for memory before designing PCB connection interface. ALTIUM DESIGNER SPICE MODEL ADD LIBRARY DRIVERSIncorporate function with Sporty 3D Component Model Drivers for Layout Those best suited for use on PCBs are surface mount connectors, although many through-hole connectors are used on PCBs for both robustness and for the ability to make solid ties to internal grounding planes. There are thousands of connectors in use for electronic signal transmission. Standards for USB, RS-485, Ethernet, MIDI, SVGA, HDMI, and Radio Frequency resolve into standard mechanical design offerings in connectors. Connectors are categorized by the type of signal propagation in terms of input and output. Electrical characteristics to consider are insulation between pins and contact resistance at connection points. Mechanical features to consider are size, materials, and locking mechanisms. Observe connector placement on your PCB with 3D modeling Connectors enable Input and Output on PCBsĬonnectors are specified in pairs, one a plug, the other a socket. Whichever connector is used on the PCB must mate with its intended connection point on system devices. Connectors have two parts to enable attachment from your PCB to other PCBs, cables, or devices within an electrical system. Used to house conductive pin for connections to pads on the circuit board that interface input-output (IO) signals with other equipment within the system. They are some of the larger electro-mechanical components on a printed circuit assembly. Printed Circuit Board Connector Use Within Electrical SystemsĬonnectors in electrical design provide connection for signals traveling either into or out of, the printed circuit assembly. Ease of collaboration drives elegant designs for IO within your design. STEP files for easy sharing with mechanical designers. The unified environment imports, as well as exports. Footprint editors allow addition of the latest and greatest connector offerings by vendors as well. This ensures, for example, appropriate use of gold plating on gold fingers or smart terminal and pin placement in the printed circuit board PCB design.Īltium Designer provides libraries containing thousands of connector styles along with footprints and 3D models. With chosen components comes footprints with land patterns and housing dimensions for the conductive materials of the connector. Defining communication channels informs connector component selection. ALTIUM DESIGNER SPICE MODEL ADD LIBRARY SERIALProtocols for input and output like universal serial bus (USB) and Ethernet all require physical electro-mechanical connectors between equipment and their printed circuit assemblies.īuilding connectors onto printed circuit assemblies requires definition of communication channels in both ECAD and MCAD modeling tools. Now decades into digital systems data is flying across the room and across the world’s communication needs. In this guide to PCB connectors, we’ll take a look at connectors within electrical systems, how they benefit from ECAD/MCAD tools, and optimal design specifics like appropriate cable connectors or gold fingers gold plating.Ĭonnectors abound on printed circuit assemblies given integrated electrical equipment and their internal electronics.
