Large Size Low Warpage Alumina Ceramic Substrate

  Large Size Low Warpage Alumina Ceramic Substrate   Large scale ceramic substrates are our company's core products, such as 240 * 280 * 1mm, 95 * 400 * 1mm and other large series ceramic substrate products, which have received unanimous praise from customers.   Typically, with ceramic substrates produced by tape-casting, the thinner the product, the greater the camber. For instance,conventional products such as 120*120*0.5, 127*127*0.5, 138* 190*0.5/0.635 generally have more than 0.39% camber.Our company adopts a special fiat fring technique to solve the problem,reducing the camber to less than 0.25%.     Ceramic substrate raw materials are often mixed with iron containing oxides.With high temperature sintering,products willdevelop red spots,affecting not only the whiteness of the product,but also the electrical properties of the product such as volumeresistivity and dielectric strength.The unique iron removal process developed by our company reduces the…
