Basa rekuongorora kweakasiyana SMT chitarisiko chekuongorora michina AOI

a) : Inoshandiswa kuyera solder paste kudhinda mhando yekuongorora muchina SPI mushure memuchina wekudhinda: SPI inspection inoitwa mushure meiyo solder paste kudhinda, uye kukanganisa mukudhinda kunowanikwa, nekudaro kuderedza kukanganiswa kwekutengesa kunokonzerwa neasina solder paste. kudhinda kusvika padiki.Kukanganisa kudhinda kunosanganisira pfungwa dzinotevera: kusakwana kana kuwandisa solder pamapedhi;kudhinda offset;mabhiriji emarata pakati pemapedhi;ukobvu uye huwandu hweakadhindwa solder paste.Panguva ino, panofanirwa kuve neine simba process monitoring data (SPC), senge kudhinda offset uye solder vhoriyamu ruzivo, uye ruzivo rwemhando yeakadhindwa solder ichagadzirwawo kuti iongororwe uye ishandiswe nevashandi vekugadzira maitiro.Nenzira iyi, maitiro anovandudzwa, maitiro anovandudzwa, uye mari inoderedzwa.Iyi mhando yemidziyo parizvino yakakamurwa kuita 2D uye 3D mhando.2D haigone kuyera ukobvu hwesolder paste, chete chimiro chesolder paste.3D inogona kuyera ese ukobvu hweiyo solder paste uye nzvimbo ye solder paste, kuitira kuti huwandu hweiyo solder paste iverengerwe.Ne miniaturization yezvikamu, ukobvu hweiyo solder paste inodiwa kune zvikamu zvakaita se 01005 ingori 75um, ukuwo ukobvu hwezvimwe zvakajairika zvikamu zvakakura zvinosvika 130um.Iyo otomatiki printer inogona kudhinda akasiyana solder paste ukobvu yabuda.Naizvozvo, chete 3D SPI inogona kusangana nezvinodiwa zveramangwana solder paste process control.Saka rudzii rweSPI yatinganyatso kuzadzisa zvinodiwa nehurongwa mune ramangwana?Zvikuru izvi zvinodiwa:

1. Inofanira kunge iri 3D.
2. Yepamusoro-kumhanya yekuongorora, ikozvino laser SPI ukobvu kuyerwa kwakaringana, asi kumhanya hakugone kuzadzisa zvizere zvinodiwa zvekugadzira.
3. Kururamisa kana kuchinjika magnification (Optical uye digital magnification ma parameter akakosha, aya ma parameter anogona kuona kugona kwekupedzisira kuona kwechishandiso. Kuti uone nemazvo 0201 uye 01005 zvishandiso, optical uye digital magnification kwakakosha, uye zvinodikanwa kuve nechokwadi kuti yekuongorora algorithm yakapihwa kune software yeAOI ine mhinduro yakakwana uye ruzivo rwemufananidzo).Nekudaro, kana pixel yekamera yagadziriswa, kukwidziridzwa kunopesana neFOV, uye saizi yeFOV ichakanganisa kumhanya kwemuchina.Pabhodhi rimwe chete, zvikamu zvakakura uye zviduku zviripo panguva imwe chete, saka zvakakosha kusarudza zvakakodzera optical resolution kana kugadziriswa optical resolution maererano nehukuru hwezvikamu pane chigadzirwa.
4. Optional light source: kushandisa programmable light sources ichave nzira yakakosha yekuonesa kuwanda kwekuona chirema.
5. Kunyanya kurongeka uye kudzokororwa: Iyo miniaturization yezvikamu inoita kuti iko kurongeka uye kudzokorora kwemidziyo inoshandiswa mukugadzira maitiro akanyanya kukosha.
6. Ultra-low misjudgment rate: Chete nekudzora mwero wakasarudzika wekukanganisa ndipo panogona kuwanikwa, kusarudzwa uye kushanda kweruzivo rwunounzwa nemushini kuchirongwa ichi kunyatso shandiswa.
7. SPC process yekuongorora nekukanganisa kugovana ruzivo neAOI kune dzimwe nzvimbo: ine simba SPC process ongororo, chinangwa chekupedzisira chekuongorora chitarisiko ndechekuvandudza maitirwo, kururamisa maitiro, kuwana mamiriro akakwana, uye kutonga mutengo wekugadzira.

b) .AOI pamberi pevira: Nekuda kweminiaturization yezvikamu, zvakaoma kugadzirisa 0201 chikamu chakaremara mushure mekutengesa, uye kukanganisa kwe01005 zvikamu hazvigone kugadziriswa zvakanyanya.Naizvozvo, iyo AOI pamberi pechoto ichawedzera kukosha.Iyo AOI pamberi pechoto inokwanisa kuona kukanganiswa kwemaitiro ekuisa senge kusarongeka, zvikamu zvisiri izvo, zvisipo, zvikamu zvakawanda, uye reverse polarity.Naizvozvo, iyo AOI pamberi pechoto inofanira kunge iri online, uye zvinonyanya kukosha zviratidzo zvinomhanya zvakanyanya, kukwirira kwakarurama uye kudzokorora, uye kuderera kwekutonga zvisirizvo.Panguva imwecheteyo, inogonawo kugovera ruzivo rwe data nehurongwa hwekudyisa, kungoona zvisizvo zvikamu zvekuwedzera mafuta panguva yekuwedzera, kuderedza mishumo yehurongwa, uye zvakare kutumira ruzivo rwekutsauka kwezvikamu kune SMT programming system kugadzirisa. iyo SMT muchina chirongwa nekukurumidza.

c) AOI mushure mechoto: AOI mushure mechoto yakakamurwa kuita mafomu maviri: online uye kunze kweindaneti maererano nenzira yebhodhi.AOI mushure mevira ndiyo muchengeti wegedhi wekupedzisira wechigadzirwa, saka parizvino ndiyo inonyanya kushandiswa AOI.Inoda kuona kukanganisa kwePCB, kukanganisa kwechikamu uye zvese zvakakanganisika mumutsara wese wekugadzira.Chete matatu-mavara-yakakwirira-kupenya dome LED mwenje sosi inogona kuratidza zvizere akasiyana solder wetting nzvimbo kuti ione zvirinani kukanganiswa kwekutengesa.Naizvozvo, mune ramangwana, chete AOI yechiedza ichi chine nzvimbo yekuvandudzwa.Ehe, mune ramangwana, kuitira kubata nePCB dzakasiyana Kurongeka kwemavara uye matatu-mavara RGB zvakare inorongwa.Zvinonyanya kushanduka.Saka imhando ipi yeAOI mushure mevira inogona kuzadzisa zvido zveSMT yedu yekuvandudza kugadzira mune ramangwana?Ndiko kuti:

1. high speed.
2. Yakanyanya kurongeka uye yakakwirira kudzokorora.
3. Makamera akakwira-resolution kana makamera akasiyana-siyana: kusangana nezvinodiwa zvekumhanya uye kurongeka panguva imwe chete.
4. Kusafungira kwakaderera uye kutadza kutonga: Izvi zvinoda kuvandudzwa pasoftware, uye kutariswa kwehunhu hwewelding ndiko kunokonzeresa kusanzwisisa uye kutadza kutonga.
5. AXI mushure mechoto: Kukanganisa kunogona kuongororwa kunosanganisira: majoini e solder, mabhiriji, tombstones, solder isina kukwana, pores, asipo zvikamu, IC yakasimudza tsoka, IC shoma tin, etc. Kunyanya, X-RAY inogonawo kuongorora zvakavanzwa solder majoini akadaro. seBGA, PLCC, CSP, nezvimwewo. Chinhu chakanaka chekuwedzera kune chiedza chinooneka AOI.
