Buyini ubuchwepheshe bokuhlola i-AOI
I-AOI wuhlobo olusha lokuhlola ubuchwepheshe obulokhu bukhuphuka ngokushesha eminyakeni yamuva.Njengamanje, abakhiqizi abaningi bethule imishini yokuhlola ye-AOI.Lapho utholwa ngokuzenzakalelayo, umshini uskena i-PCB ngokuzenzakalelayo ngekhamera, uqoqe izithombe, uqhathanise amalunga ahloliwe e-solder namapharamitha afanelekayo ku-database, uhlola amaphutha ku-PCB ngemva kokucutshungulwa kwesithombe, bese ubonisa / umaka amaphutha ku-PCB ngokusebenzisa. isibonisi noma umaki ozenzakalelayo ukuze abasebenzi abalungisayo balungise.
1. Izinjongo zokuqalisa: ukuqaliswa kwe-AOI kunezinhlobo ezimbili eziyinhloko zezinjongo ezilandelayo:
(1) Qeda ikhwalithi.Gada isimo sokugcina semikhiqizo uma iphuma emgqeni wokukhiqiza.Uma inkinga yokukhiqiza icace kakhulu, ukuxubana komkhiqizo kuphezulu, futhi ubuningi nesivinini yizici ezibalulekile, lo mgomo uyathandwa.I-AOI ivamise ukubekwa ekugcineni komugqa wokukhiqiza.Kule ndawo, izisetshenziswa zingakwazi ukukhiqiza ulwazi olubanzi lokulawula inqubo.
(2) Ukulandelela inqubo.Sebenzisa izinto zokuhlola ukuze uqaphe inqubo yokukhiqiza.Ngokuvamile, kuhlanganisa ukuhlukaniswa kwesici okunemininingwane kanye nolwazi lokubekwa kwengxenye ye-offset.Uma ukwethembeka komkhiqizo kubalulekile, ukukhiqizwa kwengxube ephansi, kanye nokuhlinzekwa kwezingxenye ezinzile, abakhiqizi babeka kuqala lo mgomo.Lokhu kuvame ukudinga ukuthi okokusebenza kokuhlola kubekwe ezikhundleni ezimbalwa emugqeni wokukhiqiza ukuze kuqashwe isimo esithile sokukhiqiza ku-inthanethi nokuhlinzeka ngesisekelo esidingekayo sokulungiswa kwenqubo yokukhiqiza.
2. Indawo yokubeka
Nakuba i-AOI ingasetshenziswa ezindaweni eziningi emugqeni wokukhiqiza, indawo ngayinye ingathola amaphutha akhethekile, okokusebenza kokuhlola kwe-AOI kufanele kubekwe endaweni lapho ukukhubazeka okuningi kungabonakala futhi kulungiswe ngokushesha ngangokunokwenzeka.Kunezindawo ezintathu zokuhlola eziyinhloko:
(1) Ngemva kokuphrinta okunamathiselwe.Uma inqubo yokuphrinta yokunamathisela ye-solder ihlangabezana nezidingo, inani leziphambeko ezitholwe yi-ICT lingancishiswa kakhulu.Izinkinga zokuphrinta ezijwayelekile zihlanganisa okulandelayo:
A. Isoda enganele kuphedi.
B. Kukhona i-solder eningi kakhulu kuphedi.
C. Ukugqagqana phakathi kwe-solder ne-pad kubi.
D. Solder ibhuloho phakathi pads.
Ku-ICT, amathuba okuba neziphambeko ngokuhlobene nalezi zimo alingana ngokuqondile nokuqina kwesimo.Inani elincane likathayela alivamisile ukuholela ekulimaleni, kuyilapho izimo ezinzima, ezifana nokungabi bikho nhlobo, cishe njalo kubangela ukukhubazeka ku-ICT.I-solder enganele ingase ibe enye yezimbangela zezingxenye ezingekho noma amalunga e-solder avulekile.Nokho, ukunquma ukuthi ibekwe kuphi i-AOI kudinga ukuqaphela ukuthi ukulahleka kwengxenye kungase kube ngenxa yezinye izimbangela okufanele zifakwe ohlelweni lokuhlola.Ukuhlola kule ndawo kusekela ngokuqondile ukulandelelwa kwenqubo nokuhlukaniswa kwezinhlamvu.Idatha yokulawula inqubo yokulinganisa kulesi sigaba ihlanganisa ulwazi lokuphrinta kwe-offset kanye nenani le-solder, kanye nolwazi lwekhwalithi mayelana ne-solder ephrintiwe nayo ikhiqizwa.
(2) Ngaphambi kwe-reflow soldering.Ukuhlola kuqedwa ngemva kokuba izingxenye zibekwe ku-solder unama ebhodini nangaphambi kokuba i-PCB ithunyelwe kuhhavini lokugeleza kabusha.Lena indawo evamile yokubeka umshini wokuhlola, njengoba iziphambeko eziningi zokunamathisela nokubeka umshini zingatholakala lapha.Ulwazi lokulawula inqubo yobuningi olwenziwa kule ndawo luhlinzeka ngolwazi lokulinganisa lwemishini yefilimu enesivinini esikhulu kanye nezinto zokusebenza zokukhweza izinto ezinezikhala.Lolu lwazi lungasetshenziselwa ukuguqula ukubekwa kwengxenye noma ubonise ukuthi isikhwezi sidinga ukulinganiswa.Ukuhlolwa kwale ndawo kuhlangabezana nomgomo wokulandelela inqubo.
(3) Ngemuva kokufakwa kabusha kwe-solder.Ukuhlola isinyathelo sokugcina senqubo ye-SMT kuwukukhetha okudume kakhulu kwe-AOI okwamanje, ngoba le ndawo ingathola wonke amaphutha omhlangano.Ukuhlola ukugeleza kabusha kokuthunyelwe kunikeza izinga eliphezulu lokuvikeleka ngoba kuhlonza amaphutha abangelwa ukuphrinta kokunamathisela, ukubekwa kwengxenye, nezinqubo zokugeleza kabusha.
