Kodi AOI ndi chiyani

Kodi luso la kuyesa kwa AOI ndi chiyani

AOI ndi mtundu watsopano waukadaulo woyesera womwe wakhala ukukwera mwachangu m'zaka zaposachedwa.Pakadali pano, opanga ambiri akhazikitsa zida zoyesera za AOI.Mukazindikira zokha, makinawo amasanthula PCB kudzera mu kamera, amasonkhanitsa zithunzi, kufananiza zolumikizira zoyeserera ndi magawo oyenerera omwe ali munkhokwe, amawunika zolakwika pa PCB pambuyo pokonza zithunzi, ndikuwonetsa / kuyika zolakwika pa PCB. chiwonetsero kapena chizindikiro chodziwikiratu kuti ogwira ntchito yokonza akonze.

1. Zolinga zokwanilitsa: kukhazikitsidwa kwa AOI kuli ndi zolinga zazikulu ziwiri izi:

(1) Kuthetsa khalidwe.Yang'anirani momwe zinthu ziliri zomaliza zikachoka pamzere wopangira.Pamene vuto la kupanga likuwonekera bwino, kusakaniza kwa mankhwala kumakhala kwakukulu, ndipo kuchuluka kwake ndi liwiro ndilo zinthu zofunika kwambiri, cholinga ichi chimakondedwa.AOI nthawi zambiri imayikidwa kumapeto kwa mzere wopangira.Pamalo awa, zida zimatha kupanga zambiri zowongolera njira.

(2) Kutsata ndondomeko.Gwiritsani ntchito zida zowunikira kuti muwunikire momwe ntchito ikupangidwira.Nthawi zambiri, zimaphatikizanso kusanjika kwatsatanetsatane komanso chidziwitso cha kakhazikitsidwe kagawo.Pamene kudalirika kwa mankhwala kuli kofunika, kupanga kusakaniza kocheperako, ndi kukhazikika kwa zigawo, opanga amapereka patsogolo pa cholinga ichi.Izi nthawi zambiri zimafuna kuti zida zowunikira ziziyikidwa m'malo angapo pamzere wopangira kuti ziwunikire momwe zinthu ziliri pa intaneti ndikupereka maziko ofunikira pakusintha kwakupanga.

2. Malo oyika

Ngakhale AOI ikhoza kugwiritsidwa ntchito m'malo angapo pamzere wopangira, malo aliwonse amatha kuzindikira zolakwika zapadera, zida zowunikira za AOI ziyenera kuyikidwa pamalo pomwe zolakwika zambiri zitha kudziwika ndikuwongolera mwachangu.Pali malo atatu akuluakulu oyendera:

(1) Pambuyo posindikiza phala.Ngati makina osindikizira a solder akukwaniritsa zofunikira, chiwerengero cha zolakwika zomwe zapezeka ndi ICT zikhoza kuchepetsedwa kwambiri.Zowonongeka zosindikiza zikuphatikizapo izi:

A. Kusakwanira solder pa pedi.

B. Pali solder wambiri pa pad.

C. Kuphatikizika pakati pa solder ndi pad ndikovuta.

D. Solder mlatho pakati pa ziyangoyango.

Mu ICT, kuthekera kwa zolakwika zokhudzana ndi izi ndizofanana mwachindunji ndi kuuma kwa zomwe zikuchitika.Kuchepa kwa malata sikumabweretsa chilema, pomwe milandu yayikulu, monga yopanda malata, nthawi zambiri imayambitsa zolakwika mu ICT.Kusakwanira solder kungakhale chimodzi mwa zifukwa za kusowa zigawo kapena lotseguka solder olowa.Komabe, kusankha komwe tingayike AOI kumafuna kuzindikira kuti kutayika kwa chigawocho kungakhale chifukwa cha zifukwa zina zomwe ziyenera kuphatikizidwa mu dongosolo loyendera.Kuyang'ana pamalowa kumathandizira kutsata ndondomeko ndi mawonekedwe.The kachulukidwe ndondomeko ulamuliro deta pa siteji imeneyi monga kusindikiza kuchotsera ndi solder kuchuluka zambiri, ndi Mkhalidwe zambiri za kusindikizidwa solder komanso kwaiye.

(2) Pamaso pa reflow soldering.Kuyang'anirako kumatsirizidwa pambuyo poti zigawozo zayikidwa mu solder phala pa bolodi ndipo PCB isanatumizidwe ku uvuni wa reflow.Awa ndi malo omwe amayika makina oyendera, chifukwa zolakwika zambiri kuchokera ku phala losindikiza ndikuyika makina zitha kupezeka pano.Chidziwitso chowongolera kachulukidwe kamene kamapangidwa pamalo ano chimapereka chidziwitso cha makina opanga mafilimu othamanga kwambiri komanso zida zoyikira zinthu zomwe zili ndi mipata.Izi zitha kugwiritsidwa ntchito kusintha kayikidwe kagawo kapena kuwonetsa kuti chokweracho chikuyenera kusinthidwa.Kuyang'anira malowa kumakwaniritsa cholinga chotsata ndondomeko.

(3) Pambuyo pa reflow soldering.Kuyang'ana pa sitepe yomaliza ya ndondomeko ya SMT ndiye chisankho chodziwika kwambiri cha AOI pakadali pano, chifukwa malowa amatha kuzindikira zolakwika zonse za msonkhano.Kuwunika kwa post reflow kumapereka chitetezo chokwanira chifukwa kumazindikiritsa zolakwika zomwe zimadza chifukwa cha kusindikiza kwa phala, kuyika chigawo, ndi njira zobwereranso.
