Sei PCB (yakadhindwa redunhu bhodhi) ichifanira kupendwa nezvinhu zvinopindirana zvekupfeka?Nzira yakarurama uye nokukurumidza kupenda bhodhi redunhu?

PCB inoreva bhodhi redunhu rakadhindwa, rinova mupi wekubatanidza magetsi ezvikamu zvemagetsi.Iyo yakajairika muindasitiri yemagetsi, uye iyo conformal coating inoshandiswawo zvakanyanya.Iko hakuna kunamatira kwePCB matatu proofing glue (pendi).Muchokwadi, ndeye kushandisa dhizaini yeyakaomeswa coating paPCB.

Conformal coating zvinhu ndezvekudzivirira PCB kuti isakuvadzwe nekunze zvinhu uye kugadzirisa hupenyu hwesevhisi yePCB.Sezvo zvigadzirwa zvemagetsi zvepamusoro-soro zvine zvakakwirira uye zvakakwirira zvinodiwa zvePCB mhando, pendi yekuongorora matatu inoshandiswa zvakanyanya pamabhodhi edunhu.

Zvinhu zvinogona kukonzera PCB kukuvara:

Kunyorova ndicho chinhu chakajairika uye chinoparadza kuPCB.Kunyanya kunyorova kunoderedza zvakanyanya kudzivirira kwekudzivirira pakati pemakondakita, kukurumidza kuora, kuderedza Q kukosha, uye corrode conductors.Zvinowanzoitika kuti chikamu chesimbi chePCB chine mhangura yegirini, iyo inokonzerwa nekemikari yemhangura yesimbi ine mhute yemvura uye oksijeni.

Mazana ezvinosvibisa anowanikwa zvakasununguka pamapuranga edunhu akadhindwa ane simba rakafanana rekuparadza.Vanogona kutungamira kune mibairo yakafanana nekukukurwa kwemwando, sekuora kwemagetsi, kuora kwemakondakita uye kunyange pfupi pfupi.Izvo zvinosvibisa zvinowanzowanikwa mumagetsi emagetsi zvinogona kunge zviri zvinhu zvemakemikari zvakasara mukugadzirisa.Izvi zvinosvibisa zvinosanganisira flux, solvent release agent, metal particles uye inki yekumaka.

Kune zvakare mapoka makuru ekusvibisa kunokonzerwa nemaoko evanhu, akaita segirisi revanhu, mafingerprints, cosmetics nemasarira echikafu.Kune zvakare zvakawanda zvinosvibisa munzvimbo yekushanda, zvakaita semunyu wekupfapfaidza, jecha, mafuta, asidhi, imwe mhunga inoora uye mold.

 

Sei uchiisa glue katatu (pendi)?

Iyo PCB yakashongedzwa neyakaomeswa yekupfekedza zvinhu haingogone kuve hunyoro-huchapupu, guruva-hupupu uye kusapinda mvura, asi zvakare iine zvimiro zvekutonhora nekupisa kuvhunduka, kuramba kuchembera, kurwisa kwemwaranzi, kupikisa mhute yemunyu, ozone corrosion resistance, vibration resistance, kuchinjika kwakanaka uye kunamatira kwakasimba.Kana ichinge yakanganiswa nezvinhu zvakashata zvenzvimbo yekushanda, inogona kuderedza kana kubvisa kuderera kwekushanda kwemagetsi.

Nekuda kwenzvimbo dzakasiyana dzekushandisa dzezvakasiyana zvigadzirwa zvekupedzisira, zvinodikanwa zvekuita zveadhesive yehutatu inosimbisa ichasimbiswa.Midziyo yemumba yakaita sefiriji, muchina wekugezesa uye mahita emvura ane zvinodikanwa zvakakwirira zvekudzivirira hunyoro, nepo mafeni ekunze nemarambi emumugwagwa anoda yakanakisa anti fog performance.

 

Maitiro ekukurumidza uye nemazvo kushandisaconformal coatingkuPCB?

Muindasitiri yekugadzira PCB, mune otomatiki michina yakatsaurirwa kuvhara pendi yekudzivirira yemabhodhi edunhu -conformal coating muchina, inozivikanwawo sematatu ehumbowo pendi yekuputira muchina, matatu ehuchapupu pendi yekupfapfaidza muchina, matatu ehuchapupu pendi yekupfapfaidza, matatu euchapupu pendi yekupfapfaidza. muchina, etc., iyo yakatsaurirwa kudzora mvura uye kuvhara chidimbu chetatu cheuchapupu pendi pamusoro pePCB, sekuvhara dhizaini yephotoresist pamusoro pePCB nekupfekera, kupfapfaidza kana kuruka coating.

Iyo conformal yekuputira muchina unonyanya kushandiswa kupfapfaidza chaiyo, kupeta uye kudonha kweglue, pendi uye zvimwe zvinwiwa mukugadzirwa kwechigadzirwa kunzvimbo chaiyo yechigadzirwa chimwe nechimwe.Inogona kushandiswa kudhirowa mitsetse, madenderedzwa kana maarcs.

Conformal coating muchina mudziyo wekupfapfaidza wakagadzirirwa kupfapfaidza pendi yehumbowo hutatu.Pamusana pezvinhu zvakasiyana-siyana zvinofanirwa kupfapfaidzwa uye iyo inoshandiswa kupfapfaidza mvura, kusarudzwa kwechikamu chemushini wekuputira muhutano hwemichina yakasiyanawo.Iwo matatu anti pendi yekuputira muchina anotora yazvino kombiyuta yekudzora chirongwa, iyo inogona kuona matatu-axis yekubatanidza.Panguva imwecheteyo, yakashongedzerwa nekamera yekumisikidza uye yekutevera system, iyo inogona kunyatso kudzora nzvimbo yekupfapfaidza.
