3m Iyo inoshandiswa kune PCB mutengesi masking uye zvimwe zvakanyanyisa tembiricha zvinoshandiswa.
"Shandisa 3m ™ polyimide firimu tepi 5413 yePCB mutengesi masking uye zvimwe zvakakwirira zvekushandisa mukati mehukuru hwe73 ° C kusvika 260 ° C. Iyi amber yakarongedzwa, 2.7 mil thick tepi inogadzirwa nefirimu rekurima uye silicone afesive. Iyo zvakare inoratidza polyethy tepi core pane kadhibhodi. Iyo Silicone ADhesive's yakanyanya kupisa tembiricha inogadzirisa chinonamatira iyo inobatsira kubvisa kuchenesa, kukubvumira kuti urambe uchigadzira kumusoro. Firimu rePolyimi rinopa kusunungurwa kwakanaka sezvo risinganyoreri uye rinogara rakapfava rakagadzikana pakudziya kwakanyanya - kudzivirira rework. Nzvimbo dzakachengetedzwa nekuda kwemapipi aya murazvo Retared, makemikari uye radiation kuramba, kudzora mutengo wekutsiva. "
