IC Substrate PCB Between the microworld of PCBs and the nanoworld of silicon dies, IC substrates offer strong linkages. They have a supporting base in the middle and are made up of numerous layers. Drill holes & conductor routes on IC substrates are denser than on traditional PCBs. An IC package’s substrate is the component […]
High-Frequency PCB Whether rigid or flexible, the high-frequency printed circuit board provides quicker signal flow rates and then a frequency range of up to 100 GHz. It’s significant to note that a variety of materials are created to function at high-frequency regions. Low levels of thermal expansion, a reduced dissipation factor, and a lower dielectric […]
Blind and Buried Vias An exterior layer of a board will be connected to an inner layer by a blind via. Nevertheless, it does not traverse the full PCB. The board contains a concealed through that connects the inner surface without touching the outer layers. Additionally, a through-hole that connects all the layers runs vertically […]
Heavy Copper PCB A circuit board having an exterior and inner copper layer thickness of less than 3 oz per square foot is referred to as a heavy copper PCB. A circuit board’s thicker plating is what qualifies it as a heavy copper PCB. Through the use of plated holes and sidewalls, copper thickness is […]
Teflon PCB High-frequency PCBs utilizing polytetrafluoroethylene (PTFE) as their PCB substrate are known as Teflon PCBs or PTFE PCBs. Teflon PCBs transmit impulses at frequencies up to 5 GHz. Dupont Corporation markets its PTFE materials under the name Teflon, and because of its widespread recognition, people often referred to PTFE substrate PCBs used only for […]
Rogers PCB The Rogers firm manufactures the basic materials for the high-frequency board known as the Rogers PCB. Epoxy resin distinguishes it from traditional PCB boards (FR4). It utilizes a ceramic base as just the high-frequency material and lacks a glass fibre in the middle. The thermal stability and dielectric constant of Rogers are superior. […]
Impedance Control PCB Impedance control involves checking that particular traces’ impedance fall within the designer-specified ranges when the PCB is being manufactured. PCBs frequently adopt a multi-layer construction, and there are numerous ways to design the control impedance. Regardless of the technique employed, the impedance level will be established by the insulating material’s electrical properties […]
Gold Finger PCB The columns with gold plating along the interconnecting borders of printed circuit boards are known as “gold fingers” (PCBs). Gold fingers are used to link a supplementary PCB to a computer’s motherboard. A PCB’s edge may have a small column of rectangle PCB pads with hard-gold plating for connections. PCB gold fingers […]
Custom PCB Small electrical components and printed strands of conductive material, including such copper, can be found on a custom PCB; Regardless of the intricacy of the component, it is utilised to combine circuits as well as other electrical components while conserving space. There are some electrical projects that may require intricate circuitry that must […]
RF PCB An RF Circuit Board is what? In general, any higher-frequency PCB that performs above 100MHz is regarded as a RF circuit board by the PCB industry. Anything above 2GHz inside the radio frequency category is a microwave PCB. A signal with an extremely high frequency is called radio frequency, or RF. The requirements […]
