Abstract

Keksintö liittyy piirilevyjärjestelyyn piirilevyn (11) suojaamiseksi poraamisen aikana esiintyvältä mekaaniselta rasitukselta, käsittäen piirilevyn (11), jolla on kimmomoduuli; ensimmäisen suojakerroksen (12), joka on järjestetty sulkemaan piirilevy (11) sisäänsä, ensimmäisen suojakerroksen (12) omatessa kimmomoduulin; ja toisen suojakerroksen (13), joka on järjestetty sulkemaan ensimmäinen piirilevy (12) sisäänsä vähintään osittain, toisen suojakerroksen (13) omatessa kimmomoduulin; jolloin ensimmäisen suojakerroksen (12) kimmomoduuli on erisuuri toisen suojakerroksen (13) kimmomoduulin kanssa; piirilevy (11) on ensimmäisen suojakerroksen (12) tukema; ja ensimmäinen suojakerros (12) on toisen suojakerroksen (13) tukema. Keksintö liittyy myös poraustyökaluun (2), joka käsittää ontelon (21) piirilevyn (11) vastaanottamiseksi poraustyökalun (2) sisään ja yllä kuvatun piirilevyjärjestelyn (1) järjestettynä onteloon (21).The invention relates to a circuit board arrangement for protecting a circuit board (11) from mechanical stress during drilling, comprising a circuit board (11) having a modulus of elasticity; a first protective layer (12) arranged to enclose the circuit board (11), the first protective layer (12) having a modulus of elasticity; and a second protective layer (13) arranged to enclose the first circuit board (12) at least partially, the second protective layer (13) having an elastic modulus; wherein the elastic modulus of the first protective layer (12) is different from the elastic modulus of the second protective layer (13); the printed circuit board (11) being supported by the first protective layer (12); and the first protective layer (12) is supported by the second protective layer (13). The invention also relates to a drilling tool (2) comprising a cavity (21) for receiving a circuit board (11) inside a drilling tool (2) and a circuit board arrangement (1) as described above arranged in the cavity (21).
