Abstract (en)

[origin: WO2018024426A1] The invention relates to a printed circuit board, preferably for use in a fuel fill-level sensor and in a fuel fill-level measuring system, comprising conducting tracks (4, 5) formed on two sides of a ceramic substrate (2), wherein the ceramic substrate (2) has at least one metallized hole (3) for through-connection, which hole connects the conducting tracks (4, 5) to each other. The hole (3) of the sintered ceramic substrate (2) is filled with a metal-containing sintering paste introduced under compression pressure. In the fully sintered state, said sintering paste enters into at least one integral bond with the ceramic substrate (2) and completely fills the hole. The invention further relates to a method for producing such a printed circuit board.
