A printed circuit board (PCB) is an essential component of most electronic devices. It provides the mechanical structure to mount and interconnect electronic components using conductive tracks and pads etched from copper sheets onto a non-conductive substrate. Test points on a PCB provide access to test and measure various signals Read more…
Rogers Corporation pioneered some of the earliest commercial laminate materials used as insulating dielectric substrates for manufacturing printed circuit boards (PCB). Their branded materials offer enhanced electrical and thermal performance meeting demanding microwave applications. FR4 constitutes the baseline cost-effective epoxy-glass laminate grade heavily utilized across majority of electronics over many Read more…
SMT stands for “Surface Mount Technology” referring to a method of mounting electronic components onto the surface of printed circuit boards (PCB) rather than passing component leads through holes to solder on the opposite side. First appearing commercially in the 1960s, surface mount became widely adopted by the late 1980s. Read more…
A “footprint” in printed circuit board design refers to the pattern of copper pads, lines, and holes defining the area where a component connects onto a PCB. Like a human footprint pressed into sand, this imprint outlines the physical interface bridging components to circuit boards. Standardized footprints allow reliable assembly Read more…
Impedance describes the total measure of opposition to electrical current flow within a circuit. Managing impedance proves vital for avoiding unintended resistance that degrades signals transferred across traces in high-frequency printed circuit board (PCB) designs. By mathematically modeling a PCB stackup configuration, engineers determine expected impedance values for board layouts Read more…
Turnkey PCB assembly refers to a streamlined service provided by electronics manufacturers where they handle the complete process of assembling printed circuit boards (PCBs). This spans from procuring components to soldering to post-production testing. The customer simply provides their finished board design files and bill of materials (BOM) to the Read more…
A Gerber file is a type of computer-aided design (CAD) file format used for printed circuit boards (PCBs). Gerber files are used to communicate design data from CAD software to PCB fabrication equipment. Gerber files contain vector images of the different layers of a PCB, including copper layers, solder mask, Read more…
