1.The inorwadza mwando kuti zvemagetsi zvinoriumba uye yose muchina
Most zvemagetsi zvigadzirwa zvinoda anodawo uye kuchengetera pasi pakaoma conditions.According nokuongorora, kupfuura kota maindasitiri kugadzira zvinhu zvakaipa zvenyika vane ukama dampness.For electronic indasitiri, ari dampness dzakakonzerwa yave imwe huru zvinokonzera kukanganisa chatingatevedzera zvigadzirwa.
(1) revatema akadhindwa redunhu bhodhi: zviri dampness kuti mwando kuti semiconductor indasitiri dzinowanzotsigi- wakaratidzwa mwando kuti anogona kupinda munzvimbo IC mukati kuburikidza IC epurasitiki kavha uye kubva nembambo nedzimwe pakakoromorwa, ichibereka IC mwando Absorção de Água chinonakidza.
Water mhute anovaka panguva kudziyisa kwacho ari SMT pcb assmblling muitiro, kusika kumanikidza unounza IC nebwe pasuru kutsemuka uye oxidize chicherwa mukati IC mudziyo, zvichiguma chigadzirwa kukundikana. Uyezve, kana mudziyo ari pcb bhodhi nomoto muitiro, nokuda nokubudiswa mvura mhute kumanikidzwa, kuchaita kuti weld.
Kubva musi IPC - M190 J - STD - 033 mureza, zvinotevera kugara mhepo uye mwando hwaiitwa SMD zvinoriumba, zvakafanira kuiisa pasi 10% RH mwando dzokupisa nguva yakaitika muchoto kuti 10 nguva iyoyo, "workshop" upenyu of chinhu kudzorerawo kudzivisa chinyorwa, nechokwadi kuchengeteka.
(2) LCD mudziyo: LCD chidzitiro LCD mano akadai girazi uye chamber, kunyange Sefa mubishi okuwana rokuchenesa nokuomesa, asi pashure kutonhora ayo vachange sei kubudikidza mwando, kuderedza muzana vanopfuura of products.Therefore, zvinofanira kuchengetwa nenzira yakaoma ezvinhu pasi 40% RH pashure kuchenesa uye kuomesa.
(3) zvimwe zvigadzirwa zvinoriumba: capacitors, zvedongo zvinoriumba, connectors, haizoshandisi, pokunamatidza pcb, rekristaro, nesilicon, Goldstone oscillator, SMT namira guruu, electrode zvinhu, zvemagetsi namatidza, mukuru kupenya mano, etc, zvose zvichashaya ne kunyorova kukuvara.
(4) mukushanda kwacho zvemagetsi: Semi-dzapedza zvigadzirwa ari pasuru unotevera muitiro; pcb kavha vasati uye pashure encapsulation kubatanidza; The IC, BGA uye pcb kuti vasina kushandiswa Pashure nekukatanura, Waiting nokuti pokunamatidza mudziyo; The mudziyo kuti akagadzirira kuti vakadzokera tembiricha pashure kubikira; Unpacked apedza zvigadzirwa, nezvimwewo, zvichashaya nokuda dampness.
(5) vanhu rakapedzwa zvigadzirwa vacharaswa dzaparadzwa nokuda mwando munguva warehousing process.If kuchengetera nguva iri kuresa pamatunhu mwando, zvichaita kuti kukundikana kuitika, uye kombiyuta bhodhi cpus achaita ndarama nomunwe oxidation kuti chikonzero kukundikana kubatana.
Kugadzirwa zvigadzirwa maindasitiri zvigadzirwa uye kuchengetera ezvinhu chezvinhu zvinofanira pazasi 40% .Some mhando dzinodawo zvishoma mwando.
KingSong Technology rakafanana chete-kumisa Assembly pcb Manufacturer , ane yakaoma kuzvidzora kuti zvemagetsi zvinoriumba, kuitira kubudirira kwayo, sezvo saka kupa vatengi yedu quality.if zvakanaka muine PCBA chirongwa, anobvumirwa nesu pachena, ndatenda!
