摘要

Anti-pressure linear circuit board manufacture comprises providing a first circuit board (2), and cutting the first circuit board to form cut grooves (21). The cut grooves define the second circuit board. The second circuit board is connected to the first circuit board via a connection portion. The first circuit board includes a main circuit. The second board includes a calibrated pressure sensor and an OP amplifier. The method includes precisely calibrating the pressure sensor and the OP amplifier. The main circuit on the first circuit board is electrically connected to the pressure sensor and the OP amplifier on the second circuit board via printed circuits on the connection portion. An independent claim is included for anti-pressure linear circuit board.
