PCB Material Properties You Should Consider During Board Design

WebFeb 25, 2024 · Thermal Conductivity (Κ, λ, or κ.) is a physical quantity in PCB measures, which can be defined as the rate at which heat is transferred from a heat source to cooler regions of the PCB. Talking about this, we need to know another term “Tg”, which is always misleadingly translated as “glass transition temperature. Peel strength Peel strength is a measure of the bond strength between the copper conductor and the dielectric material. It is expressed in pounds of force per linear inch (PLI, or average load per conductor width) required to … See more free leather wallet patterns pdf https://thebaylorlawgroup.com
