What is an amplifier PCB?
Amplifier modules, also known as amplifier boards, are PCB (printed circuit board) modules that have audio amplifier chips.
Amplifier modules, also known as amplifier boards, are PCB (printed circuit board) modules that have audio amplifier chips.
Some of the substrate materials used in high voltage PCBs include: BT epoxy, phenolic cured rigid laminate, high voltage Teflon (HVPF).
Maintain clearance between high voltage drop traces. Avoid any sharp turns and edges as they can act as areas for concentrated electric fields. Avoid running very high voltage traces on the inner layers of the board.
The high-frequency material most familiar to users of PCB laminates is probably polytetrafluoroethylene (PTFE), a synthetic thermoplastic fluoropolymer with excellent dielectric properties at microwave frequencies.
FR4 is the most used material in PCB construction. Circuit boards made of FR4 are strong, waterproof, and provide good insulation between copper layers, minimizing interference and supporting good signal integrity.
The standard thickness of the PCB is 1.57 mm. Some manufacturers will accommodate other specific thicknesses of 0.78mm or 2.36mm. When we say "thick" or "thin" FR4, we are usually comparing to the standard thickness of 1.57mm.
The impedance of a circuit board trace depends on: trace width and thickness. The height of the dielectric layer between the signal trace and the reference plane. The dielectric constant of the dielectric material used in the circuit board.
Impedance is the combination of capacitance and inductance when a circuit operates at high frequencies.
Two types: electroless nickel immersion gold and electroplated hard gold.
Higher stability, best to withstand high power density designs, ideal for multilayer and HDI PCBs.
The circuit board material must be flame retardant, cannot burn at a certain temperature, but can only soften. This temperature point is called the glass transition temperature (Tg). A higher Tg point means higher temperature requirements during laminatio
Tg, or glass transition temperature, is a basic material parameter of temperature (°C). It defines the temperature at which the substrate becomes mechanically unstable. Tg is the temperature value that guarantees the mechanical stability of the PCB during
