  • Non-conductive substrate with tracks formed by sand blasting
    Patent number: 10335922
    Abstract: A method for forming track(s) on low temperature co-fired ceramic (LTCC) substrate, the method comprising the steps of, forming a layer of coating material on an operative face of the LTCC substrate, disposing a stencil on the layer of coating material thereby covering a selected portion of the layer of coating material while leaving exposed a portion of the layer of coating material corresponding to the track(s) to be formed and forming an assembly of the LTCC substrate, the layer of coating material and the stencil, eroding the exposed portion of the layer of coating material by propelling an abrasive material using a blasting gun towards the assembly on the face on which the layer of coating material is formed and the stencil is disposed and separating the stencil from the abraded assembly, wherein the abrasive material has a composition that is compatible with that of the LTCC substrate.
