nekuvandudzwa kwehunyanzvi hwemagetsi, mapuranga edunhu anoshandiswa zvakanyanya munzvimbo dzakasiyana siyana, anenge ese emagetsi emagetsi ane mabhodhi edunhu.High-kuguma motokari, avhiyesheni, zvokurapa zvemagetsi, zvakajairika akangwara musha, kutaurirana zvemagetsi, midziyo yemumba, etc. pcb bhodhi somutakuri wemhando dzakasiyana-siyana zvemagetsi zvinoriumba, tamba kushanda kushanda kwezvikamu zvakasiyana, zvinotevera NeoDen kukuudza pamusoro pcb bhodhi. kuchengetedza tembiricha uye mwando uye sei kuchengeta.
PCB bhodhi yekuchengetedza tembiricha uye humidity
PCB bhodhi kugadzirwa matanho, uye zvinodiwa vari yakachena kamuri oparesheni, saka kugadzirwa pcb pamusoro zvakatipoteredza uye tembiricha uye mwando zvinodiwa zviri zvishoma kuomarara.Kupisa uye humidity hazvina kukodzera, zvinotungamirira kune pcb board corrosion, kuderedza hupenyu hwedunhu uye kuderedza kushanda kwebhodhi.Saka pcb board inofanira kuchengetwa munzvimbo yekuchengetedza yekushisa: 22-27 degrees, humidity: 50-60%.
PCB bhodhi nzira yekuchengetedza uye kuchengetedza nguva
1. PCB kugadzirwa uye kugadzirisa, inofanira kuva kekutanga kushandisa vacuum packaging, uye vacuum packaging bhegi inofanira kuva desiccant uye yakasimba kurongedza, haigoni kusangana nemvura nemhepo, kudzivisa pcb redunhu bhodhi pamusoro pfapfaidzo tini uye padhi zvishoma ndiko oxidation kukanganisa. welding uye chigadzirwa chemhando.
2. Mabhodhi ePCB anofanirwa kurongwa uye kunyorwa, mabhokisi akavharwa anofanira kuparadzaniswa kubva pamadziro, haafanirwe kuvhenekerwa nechiedza chezuva, kuchengetedza mune inofefetera uye yakaoma yekuchengetedza kabhineti ine nzvimbo yakanaka yekuchengetedza (tembiricha: 22-27 madhigirii, humidity. : 50-60%).
3. Yakareba nguva isati yashandiswa pcb redunhu bhodhi, yakanakisa munguva yepasi bhurasho matatu anti-varnish, mwando-uchapupu, guruva-uchapupu, anti-oxidation, saka pcb redunhu bhodhi kuchengetedza hupenyu hunogona kuwedzera kusvika kumwedzi 9.
4. Unpacked pcb chigamba chakapedzwa mune anogara tembiricha uye mwando kwezvakatipoteredza kuchengetedza nguva 15 mazuva, kwete anopfuura 3 mazuva pakamuri tembiricha.
5. Unpacked pcb inofanira kushandiswa mukati memazuva matatu, isina kushandiswa kumusoro inoda kushandisa zvakare static mabhegi vacuum yakavharwa.
6. SMT chigamba uye DIP pashure pcb bhodhi kuti kutakurwa uye kuiswa pamwe anti-static chibhakera.
