ApoSMT AOI muchinainogona kushandiswa munzvimbo dzakawanda pamutsara wekugadzira weSMT kuona chakakanganisika, michina yekuongorora yeAOI inofanira kuiswa panzvimbo inonyanyozivikanwa nekugadziriswa nekukasika.Kune matatu makuru ekutarisa nzvimbo:
Mushure mokunge solder paste yakadhindwa
Kana iyo solder paste kudhinda maitiro inosangana nezvinodiwa, huwandu hweICT hurema hunogona kuderedzwa zvakanyanya.Kukanganisa kudhinda kunosanganisira zvinotevera:
A.Marata ekusodha asina kukwana pastencil printer.
B. Solder yakawandisa pane solder pad.
C. Kusawirirana kwakashata kwe solder kune solder pad.
D. Zambuko rekutengesa pakati pemapedhi.
MuICT, mukana wekukanganisa maererano nemamiriro ezvinhu aya wakanyatsoenderana nekuoma kwemamiriro ezvinhu.Zvishoma zvishoma tin haawanzo tungamira kune hurema, nepo nyaya dzakakomba, senge yakakosha tin, dzinogara dzichitungamira mukukanganisa muICT.Kusakwana solder kunogona kunge kuri chikonzero chekurasikirwa kwechikamu kana kuvhurika solder majoini.Zvakadaro, kusarudza pekuisa AOI kunoda kuziva kuti kurasikirwa kwechikamu kunogona kuitika nekuda kwezvimwe zvikonzero zvinofanirwa kuverengerwa muchirongwa chekuongorora.Iyi ongororo yenzvimbo inonyanya kutsigira nzira yekutevera uye maitiro.Quantitative process control data pane ino nhanho inosanganisira kudhinda offset uye solder vhoriyamu ruzivo, nepo ruzivo rwemhando nezve yakadhindwa solder inogadzirwa zvakare.
Pamberi pareflow oven
Kuongorora kunoitwa mushure mekunge chikamu chacho chaiswa mune solder paste pabhodhi uye PCB isati yapinzwa muvira reflow.Iyi inzvimbo yakajairwa yekuisa muchina wekuongorora, sezvo hurema hwakawanda kubva kune solder paste kudhinda uye kuisa muchina kunogona kuwanikwa pano.Iyo yehuwandu maitiro inodzora ruzivo inogadzirwa panzvimbo ino inopa ruzivo pamusoro pekuenzanisa kweakakwira-kumhanya chip michina uye yakavharwa-yakaparadzana chikamu chekuisa michina.Ruzivo urwu runogona kushandiswa kugadzirisa kuiswa kwechikamu kana kuratidza kuti chinokwirisa chinoda kuenzanisa.Kuongororwa kwenzvimbo iyi kunosangana nechinangwa chekutsvaga nzira.
Mushure mokunge reflow soldering
Tarisa pakupera kweSMT process, inova ndiyo inonyanya kufarirwa sarudzo yeAOI, nekuti apa ndipo panowanikwa kukanganisa kwese kwegungano.Kuongorora kwePost-reflow kunopa hupamhi hwekuchengetedza nekuti inoratidza zvikanganiso zvakakonzerwa nekudhinda paste paste, kukwidziridzwa kwechikamu, uye maitiro ekudzokorora.
