PCBA inoreva maitiro ekukwira, kuisa uye kushambadzira isina PCB zvikamu.Iyo yekugadzira maitiro ePCBA inoda kuenda kuburikidza neakateedzana maitiro ekupedzisa kugadzira.Ikozvino, PCBFuture ichaunza akasiyana maitiro ekugadzirwa kwePCBA.
PCBA dhizaini yekugadzira inogona kukamurwa kuita akati wandei maitiro, SMT chigamba kugadzirisa → DIP plug-in kugadzirisa → PCBA kuyedzwa → kupera chigadzirwa kusangana.
Kutanga, SMT chigamba kugadzirisa link
Maitiro eSMT chip process ndeiyi: solder paste kusanganisa → solder paste kudhinda → SPI→ kukwira → reflow soldering → AOI→ rework
1, solder paste kusanganisa
Mushure mekunge solder paste yabudiswa mufiriji uye yanyungudutswa, inomutswa nemaoko kana muchina kuti ienderane nekudhinda uye kusona.
2, solder paste kudhinda
Isa solder paste pane stencil, uye shandisa squeegee kudhinda solder paste paPCB pads.
3, SPI
SPI ndiyo solder paste ukobvu detector, iyo inogona kuona kudhindwa kwesolder paste uye kudzora kudhinda kweiyo solder paste.
4. Kukwira
Zvikamu zveSMD zvinoiswa pane yekudyisa, uye iyo yekuisa muchina musoro unoisa izvo zvikamu pane yekudyisa paPCB pads kuburikidza nekuzivikanwa.
5. Reflow soldering
Pfuura iyo yakasimudzwa PCB bhodhi kuburikidza nereflow solder, uye paste-yakafanana solder paste inopisa kuti iite mvura kuburikidza nekupisa kwakanyanya mukati, uye pakupedzisira yakatonhodzwa nekusimbiswa kupedzisa soldering.
6.AOI
AOI ndeye otomatiki optical inspection, inogona kuona welding mhedzisiro yePCB board nekuongorora, uye kuona kukanganisa kwebhodhi.
7. kugadzirisa
Gadzirisa zvakakanganisika zvakaonekwa neAOI kana kuongorora nemaoko.
Chechipiri, DIP plug-in yekugadzirisa link
Maitiro eDIP plug-in kugadzirisa ndeiyi: plug-in → wave soldering → kucheka tsoka → post welding process → washing board → kuongororwa kwemhando
1, plug-in
Gadzirisa mapini ezvishandiso zveplug-in woaisa paPCB board
2, wave soldering
Iro bhodhi rakaiswa rinoiswa pasi pekuisa wave soldering.Mukuita uku, tini remvura richapfapfaidzwa paPCB board, uye pakupedzisira kutonhodzwa kuti ipedze kusodha.
3, kucheka tsoka
Mapini ebhodhi rakatengeswa akareba uye anoda kuchekwa.
4, post welding processing
Shandisa simbi yemagetsi solder kuti utengese nemaoko zvikamu.
5. Shamba ndiro
Mushure mekunge wave soldering, bhodhi rinenge rakasviba, saka unofanirwa kushandisa mvura yekugeza uye tangi yekugezesa kuichenesa, kana kushandisa muchina kuchenesa.
6, kuongororwa kwemhando
Ongorora bhodhi rePCB, zvigadzirwa zvisina kukodzera zvinofanirwa kugadziriswa, uye chete zvigadzirwa zvinokwanisa zvinogona kupinda mune inotevera maitiro.
Chechitatu, PCBA bvunzo
PCBA bvunzo inogona kukamurwa kuita ICT bvunzo, FCT bvunzo, kuchembera bvunzo, vibration bvunzo, nezvimwe.
PCBA bvunzo ndiyo bvunzo hombe.Zvinoenderana neyakasiyana zvigadzirwa uye zvakasiyana zvinodiwa nevatengi, nzira dzekuyedza dzinoshandiswa dzakasiyana.
Yechina, yakapedzwa chigadzirwa gungano
Iyo yakaedzwa PCBA bhodhi inounganidzwa kune goko, uye yozoedzwa, uye pakupedzisira inogona kutumirwa.
Kugadzirwa kwePCBA chimwe chinongedzo mushure mechimwe.Chero dambudziko mune chero chinongedzo richava nemhedzisiro yakakura kwazvo pahupamhi hwese, uye kutonga kwakasimba kwega rega rega kunodiwa.
