Kugadzirwa kwemagetsi ndeimwe yemhando yakakosha yeindasitiri yeruzivo tekinoroji.Pakugadzirwa uye kusangana kwezvigadzirwa zvemagetsi, PCBA (yakadhindwa redunhu bhodhi musangano) ndiyo inonyanya kukosha uye yakakosha chikamu.Iko kune kazhinji iyo SMT (Surface Mount Technology) uye DIP (Dual in -line package) zvigadzirwa.
Chinangwa chekutsvaga mukugadzirwa kweindasitiri yemagetsi chiri kuwedzera huwandu hwekushanda uku uchideredza saizi, kureva, kuita kuti chigadzirwa chive chidiki uye chireruke.Mune mamwe mazwi, chinangwa ndechekuwedzera mamwe mabasa kune imwechete saizi yedunhu bhodhi kana kuchengetedza basa rimwechete asi kuderedza nzvimbo.Nzira chete yekuzadzisa chinangwa ndeyekudzikisa zvigadzirwa zvemagetsi, kuzvishandisa kutsiva zvakajairwa zvikamu.Nekuda kweizvozvo, iyo SMT inogadzirwa.
SMT tekinoroji yakavakirwa pakutsiva izvo zvakajairwa zvemagetsi zvikamu newafer-mhando yemagetsi zvikamu uye kushandisa mu-tireyi yekurongedza.Panguva imwecheteyo, nzira yakajairwa yekuchera nekupinza yakatsiviwa nekunamira nekukurumidza pamusoro pePCB.Zvakare, iyo nzvimbo yepamusoro yePCB yakaderedzwa nekugadzira akawanda akaturikidzana emabhodhi kubva kune imwechete dhizaini yebhodhi.
Midziyo mikuru yeSMT yekugadzira mutsara inosanganisira: Stencil printer, SPI, pick nekuisa muchina, reflow soldering oveni, AOI.
Zvakanakira kubva kune SMT zvigadzirwa
Kushandisa SMT yechigadzirwa hakusi kwekuda kwemusika chete asiwo maitiro ayo asina kunanga pakudzikisa mutengo.SMT inoderedza mutengo nekuda kwezvinotevera:
1. Iyo inodiwa nzvimbo uye zvidimbu zvePCB zvakaderedzwa.
Nzvimbo inodiwa yePCB yekutakura zvinhu inodzikiswa nekuti saizi yezviya zvekuunganidza zvikamu zvakadzikiswa.Zvakare, iyo mari yezvinhu zvePCB yakaderedzwa, uye zvakare hapasisina mari yekugadzirisa yekuchera kune kuburikidza-maburi.Imhaka yekuti soldering yePCB muSMD nzira yakananga uye yakati sandarara pachinzvimbo chekuvimba nemapini ezvikamu muDIP kuti apfuure nemaburi akacherwa kuitira kuti atengeswe kuPCB.Pamusoro pezvo, iyo PCB dhizaini inova inoshanda zvakanyanya mukushaikwa kwemaburi-maburi, uye semhedzisiro, iyo inodiwa zvidimbu zvePCB inoderedzwa.Semuenzaniso, yekutanga mana akaturikidzana edhizaini yeDIP anogona kudzikiswa kuita maviri akaturikidzana nenzira yeSMD.Imhaka yekuti kana uchishandisa nzira yeSMD, iwo maviri akaturikidzana emapuranga achave akakwana pakukodzera mune ese wiring.Mutengo wezvikamu zviviri zvemapuranga ndezvechokwadi zvishoma pane zvezvikamu zvina zvemapuranga.
2. SMD inonyanya kukodzera kune yakawanda yakawanda yekugadzirwa
Iyo yekurongedza yeSMD inoita kuti ive sarudzo iri nani yekugadzira otomatiki.Kunyangwe kune izvo zvakajairwa zvikamu zveDIP, kune zvakare otomatiki yekuunganidza nzvimbo, semuenzaniso, yakatwasuka mhando yemuchina wekuisa, iyo yakatwasuka mhando yemuchina wekupinza, odd-fomu yekuisa muchina, uye IC yekuisa muchina;zvisinei, kugadzirwa panguva imwe neimwe unit ichiri shoma pane iyo SMD.Sezvo huwandu hwekugadzira hunowedzera kune yega nguva yekushanda, iyo unit yemutengo wekugadzira inodzikiswa.
3. Vashoma vashandisi vanodiwa
Kazhinji, vanenge vatatu vanoshanda chete vanodiwa pamutsetse wekugadzira weSMT, asi vanhu gumi kusvika makumi maviri vanodiwa pamutsetse weDIP.Nekudzikisa huwandu hwevanhu, kwete chete mari yevashandi inoderedzwa asiwo manejimendi anova nyore.
