Nemaitiro ekusimudzira eiyo miniaturization yezvikamu zveSMD uye izvo zvepamusoro uye zvepamusoro zvinodiwa zveSMT maitiro, indasitiri yekugadzira zvemagetsi ine yakakwirira uye yepamusoro zvinodiwa zvekuyedza michina.Mune ramangwana, mashopu ekugadzira eSMT anofanirwa kuve nemichina yekuyedza kupfuura yekugadzira SMT.Mhinduro yekupedzisira inofanira kuva musanganiswa weSPI + AOI pamberi pevira + AOI + AXI mushure mevira.
- Maitiro ekuita miniaturization yeSMD zvikamu uye kudiwa kweAOI michina
Nekufambira mberi kwevanhu uye nekuvandudzwa kwesainzi uye tekinoroji, michina inotakurika yakawanda inosangana nezvishuwo zvevanhu zvakasiyana, uye kugadzirwa kwacho kunowedzera uye kwakaoma, senge Bluetooth mahedhifoni, PDAs, netbooks, MP4, SD makadhi uye zvichingodaro.Kudiwa kwezvinhu izvi kwakasimudzira kuvandudzwa kweiyo miniaturization yeSMD zvikamu, uye miniaturization yezvikamu zvakasimudzirawo kuvandudzwa kwemidziyo inotakurika.Maitiro ekusimudzira eSMD passive components akaita seizvi: 0603 zvikamu zvakaonekwa muna 1983, 0402 zvikamu zvakaonekwa muna 1989, 0201 zvikamu zvakatanga kuoneka muna 1999, uye nhasi tatanga kushandisa 01005 zvikamu.
01005 zvikamu zvakatanga kushandiswa muhukuru-sensitive uye isingadhuri michina yekurapa yakadai sepacemaker.Nekugadzirwa kwakakura kwezvikamu zve 01005, mutengo wezvikamu zve 01005 wakaderera ne5 nguva kana zvichienzaniswa nemutengo pawakatanga kutangwa, saka kushandiswa kwezvikamu zve 01005 Nekuderedzwa kwemutengo, chiyero chinoramba chichiwedzerwa kune zvigadzirwa mu. dzimwe minda, nokudaro zvichikurudzira kubuda kunoenderera mberi kwezvigadzirwa zvitsva.
SMD zvikamu zvakashanduka kubva 0402 kusvika 0201 uyezve kusvika 01005. Saizi shanduko inoratidzwa pamufananidzo uri pazasi:
Saizi ye01005 chip resistor ndeye 0.4 mm × 0.2 mm × 0.2 mm, nzvimbo inongova 16% uye 44% yeaimbova maviri, uye vhoriyamu inongova 6% uye 30% yeaimbova maviri.Kune zvigadzirwa zvinonzwa saizi, kufarirwa kwe01005 kunounza hupenyu kune chigadzirwa.Ehezve, zvinounzawo matambudziko matsva nemikana kuindasitiri yekugadzira magetsi!Kugadzirwa kwe01005 zvikamu uye 0201 zvikamu zvinoisa zvakanyanya kurongeka zvinodiwa pamidziyo yekugadzira SMT kubva kumberi kuenda kumashure.
Kune zvikamu zve 0402, kuongorora kwekuona kwatove kwakaoma uye kwakaoma kugara, tisingarevi izvo zvakakurumbira zvikamu zve 0201 uye 01005 inokura.Naizvozvo, kubvumirana kweindasitiri kuti mitsetse yekugadzira yeSMT inoda michina yeAOI kuti iongororwe.Kune zvikamu zvakadai se0201, kana chikanganiso chikaitika, chinogona kungoiswa pasi pe microscope uye kugadziriswa nemichina yakakosha.Nokudaro, mari yekuchengetedza yakave yakakwirira kudarika iyo 0402. Kune zvikamu zve 01005 ukuru (0.4 × 0.2 × 0.13mm), zvakaoma kuona neziso rakashama chete, uye zvinotonyanya kuoma kushanda nekuchengetedza. nechishandiso chipi nechipi.Naizvozvo, kana iyo 01005 chikamu chine hurema mukuita, haigone kugadziriswa.Naizvozvo, nekugadzirwa kweminiaturization yemidziyo, tinoda mimwe michina yeAOI kudzora maitiro, kwete kungoona zvigadzirwa zvisina kurongeka.Nenzira iyi, tinogona kuwana kukanganisa mukuita nekukurumidza sezvinobvira, kuvandudza maitiro, uye kuderedza kuitika kwekukanganisa.
- Nenzira iyi, tinogona kuwana kukanganisa mukuita nekukurumidza sezvinobvira, kuvandudza maitiro, uye kuderedza kuitika kwekukanganisa.
Kunyange zvazvo michina yeAOI yakatanga makore makumi maviri apfuura, kwenguva yakareba, yaidhura uye ichinetsa kubata, uye zvakaonekwa zvaisagutsa.AOI yaingovepo sepfungwa uye haina kuzivikanwa nemusika.Zvakadaro, kubvira 2005, AOI yakasimukira nekukurumidza.Vatengesi vemidziyo yeAOI vabuda.Mafungiro matsva akasiyana uye zvigadzirwa zvitsva zvakabuda imwe mushure meimwe.Kunyanya, vagadziri vemidziyo yemumba yeAOI kudadisa kweChina's SMT indasitiri, uye midziyo yemumba yeAOI iri kushandiswa.Sezvineiwo, haisisiri kukwira nekudzika nezvigadzirwa zvekunze, uye nekuda kwekukwira kweAOI yemuno, mutengo weAOI wadzikira kusvika pa1/2 kusvika pa1/3 yeyakapfuura.Naizvozvo, maererano nemutengo wevashandi unochengetedzwa neAOI pachinzvimbo chekuongorora nemaoko, kutenga AOI kwakakosha, tisingarevi kuti kushandisa AOI kunogonawo kuwedzera mwero wakatwasuka wechigadzirwa uye kuwana maitiro akadzikama ekuona kupfuura. manual.Saka AOI yatove mudziyo unodiwa kune vagadziri veSMT varipo.
Mumamiriro ezvinhu akajairika, AOI inogona kuiswa munzvimbo nhatu mukugadzirwa kweSMT, mushure mekudhinda solder paste, kusati kwaita reflow soldering uye mushure mekugadzirisa reflow solder kutarisa kunaka kwezvikamu zvakasiyana.Kunyange zvazvo kushandiswa kweAOI kwave tsika, vagadziri vazhinji vachiri kungoisa AOI kuseri kwevira, uye vanoshandisa AOI semuchengeti wegedhi rekupedzisira kuti chigadzirwa chipinde muchikamu chinotevera, chete pachinzvimbo chekuongorora nemaoko.Pamusoro pezvo, vagadziri vazhinji vachiri kusanzwisisa nezve AOI.Hapana AOI inokwanisa kuwana bvunzo dzenhema, uye hapana AOI inokwanisa kuwana hapana bvunzo yakapotsa.MaAOI mazhinji anosarudza chiyero chakanaka pakati pekuyedzwa kwenhema nekupotsa bvunzo, nekuti algorithm yeAOI inzira ipi zvayo.Enzanisa sampuli yemazuva ano nekombiyuta yemuenzaniso (chingave mufananidzo kana parameter), uye ita mutongo unoenderana nekufanana.
Parizvino, kuchine makona akawanda akafa muAOI mushure mekunge choto chashandiswa.Semuyenzaniso, iyo single-lens AOI inongokwanisa kuona chikamu cheQFP, SOP, uye yenhema welding.Zvakadaro, mwero wekuona mamulti-lens AOI yeQFP neSOP tsoka dzakasimudzwa uye tin shoma inokwira ne30% chete pane iya yesingle-lens AOI, asi inowedzera mutengo weAOI uye kuoma kwehurongwa hwekushandisa.Mifananidzo iyi inogadzirwa pachishandiswa chiedza chinooneka.AOI haina simba rekuona majoini anotengeswa asingaoneki akadai seBGA asipo mabhora uye PLCC inotengeswa yenhema.
