Malo a makina a SMT AOI pamzere wopangira wa SMT

PameneMakina a SMT AOIzitha kugwiritsidwa ntchito m'malo angapo pamzere wopangira wa SMT kuti muwone zolakwika zinazake, zida zowunikira za AOI ziyenera kuyikidwa pamalo pomwe zolakwika zambiri zitha kudziwika ndikuwongolera mwachangu momwe zingathere.Pali malo atatu akulu cheke:

Pambuyo pa solder phala kusindikizidwa

Ngati solder phala ndondomeko yosindikizira akukumana zofunika, chiwerengero cha ICT zolakwika akhoza kwambiri kuchepetsedwa.Zowonongeka zosindikiza zikuphatikizapo izi:

A.Kusakwanira malata otenthetsera pachosindikizira cha stencil.

B. Solder kwambiri pa solder pad.

C. Kusalumikizana bwino kwa solder to solder pad.

D. Solder mlatho pakati pa ziyangoyango.

Mu ICT, kuthekera kwa zolakwika zokhudzana ndi izi ndizomwe zimayenderana ndi kuuma kwa zomwe zikuchitika.Kuchepa pang'ono kwa malata sikumabweretsa zilema, pomwe milandu yayikulu, monga malata oyambira, nthawi zambiri imatsogolera ku zolakwika mu ICT.Kusakwanira kwa solder kungakhale chifukwa cha kuwonongeka kwa chigawo kapena kutseguka kwa solder.Komabe, kusankha komwe tingayike AOI kumafuna kuzindikira kuti kutayika kwa chinthu kungachitike pazifukwa zina zomwe ziyenera kuphatikizidwa mu dongosolo loyendera.Kuyang'anira malowa kumathandizira kwambiri kutsata ndondomeko ndi mawonekedwe.Kachulukidwe ndondomeko ulamuliro deta pa siteji imeneyi zikuphatikizapo kusindikiza kuchotsera ndi solder voliyumu zambiri, pamene mfundo za khalidwe la solder kusindikizidwa amapangidwanso.

Pambuyo pareflow uvuni

Kuyang'anira kumachitika pambuyo chigawocho chikayikidwa mu solder phala pa bolodi ndipo PCB isanadyetsedwe mu ng'anjo ya reflow.Awa ndi malo omwe amayika makina oyendera, chifukwa zolakwika zambiri kuchokera ku makina osindikizira a solder ndikuyika makina zingapezeke pano.Chidziwitso chowongolera kachulukidwe kamene kamapangidwa pamalo ano chimapereka chidziwitso pakuwongolera makina othamanga kwambiri komanso zida zoyikiramo zida zapakatikati.Izi zitha kugwiritsidwa ntchito kusintha kayimidwe kagawo kapena kuwonetsa kuti chokwera chikufunika kusinthidwa.Kuyang'anira malowa kumakwaniritsa cholinga chotsata ndondomekoyi.

Pambuyo pa reflow soldering

Yang'anani kumapeto kwa ndondomeko ya SMT, yomwe ndi njira yotchuka kwambiri ya AOI, chifukwa apa ndi pamene zolakwika zonse za msonkhano zingapezeke.Kuyang'ana pambuyo pa reflow kumapereka chitetezo chokwanira chifukwa kumazindikiritsa zolakwika zomwe zimayambitsidwa ndi kusindikiza kwa solder paste, kukwera kwa zigawo, ndi njira yobwezeretsanso.
