Kuwanda kwegungano kwakakwira, zvigadzirwa zvemagetsi zvidiki muhukuru uye huremu huremu, uye vhoriyamu uye chikamu chezvikamu zvechigamba zvinongori 1/10 yezvimiro zveplug-in.

Mushure mekusarudzwa kwakawanda kweSMT, huwandu hwezvigadzirwa zvemagetsi hunoderedzwa ne40% kusvika 60%, uye uremu hunoderedzwa ne60% kusvika 80%.

Kuvimbika kwepamusoro uye kusimba kwakasimba kwekudengenyeka.Low defect rate ye solder joint.

Good high frequency maitiro.Yakaderedzwa electromagnetic uye RF kupindira.

Zviri nyore kuwana otomatiki, kuvandudza kugadzirwa kwakanaka.Deredza mutengo ne30% ~ 50%.Sevha data, simba, zvishandiso, manpower, nguva, nezvimwe.

Sei uchishandisa Surface Mount Skills (SMT)?

Zvigadzirwa zvemagetsi zvinotsvaga miniaturization, uye iyo perforated plug-in zvikamu zvakashandiswa hazvichagone kudzikiswa.

Basa rezvigadzirwa zvemagetsi rinowedzera kuzara, uye iyo yakabatanidzwa yedunhu (IC) yakasarudzwa haina mativi ane perforated, kunyanya makuru-akanyanya, akabatanidzwa zvakanyanya ics, uye pamusoro pechigamba zvikamu zvinofanirwa kusarudzwa.

Chigadzirwa chakawanda, kugadzira otomatiki, fekitori kune yakaderera mutengo wakakwira kuburitsa, kugadzira zvigadzirwa zvemhando yepamusoro kusangana nezvinodiwa nevatengi uye kusimbisa kukwikwidza kwemusika.

Kuvandudzwa kwezvinhu zvemagetsi, kugadzirwa kwemasekete akabatanidzwa (ics), kushandiswa kwakawanda kwe data semiconductor

Electronic tekinoroji shanduko yakakosha, kudzingirira maitiro epasirese

Sei uchishandisa nzira isina-yakachena muunyanzvi hwekukwira pamusoro?

Mukugadzira, mvura yakaraswa mushure mekuchenesa kwechigadzirwa inounza kusvibiswa kwemhando yemvura, pasi nemhuka nemiti.

Pamusoro pekuchenesa mvura, shandisa organic solvents ine chlorofluorocarbons (CFC&HCFC)Kuchenesa kunokonzerawo kusvibiswa uye kukanganisa kumhepo nemhepo.Izvo zvakasara zvekuchenesa mumiririri zvinokonzeresa ngura pabhodhi remuchina uye kukanganisa zvakanyanya kunaka kwechigadzirwa.

Deredza kuchenesa kushanda uye mari yekugadzirisa muchina.

Hapana kuchenesa kunogona kuderedza kukuvadzwa kunokonzerwa nePCBA panguva yekufamba uye kuchenesa.Pachine zvimwe zvikamu zvisingagoni kucheneswa.

Iyo flux yakasara inodzorwa uye inogona kushandiswa zvinoenderana nechigadzirwa chitarisiko zvinodiwa kudzivirira kutarisisa kwekuona kwekuchenesa mamiriro.

Iyo yakasara flux yakaramba ichivandudzwa kuitira kushanda kwayo kwemagetsi kudzivirira chigadzirwa chakapedzwa kubva pakudonha magetsi, zvichikonzera chero kukuvara.

Ndedzipi nzira dzekuona dzeSMT chigamba cheSMT patch processing plant?

Kuonekwa muSMT kugadzirisa inzira yakakosha yekuona mhando yePCBA, nzira huru dzekuona dzinosanganisira kutariswa kwemanyorero ekuona, solder paste ukobvu geji yekuona, otomatiki yekuona optical, X-ray yekuona, pamhepo kuyedza, kubhururuka tsono kuyedzwa, nezvimwe. nekuda kwekusiyana kwekuonekwa kwezvinhu uye maitiro ega ega nzira, nzira dzekuona dzinoshandiswa mune imwe neimwe nzira dzakasiyanawo.Munzira yekuona ye smt patch processing plant, manual visual diagnosis uye automaticOptical inspection uye X-ray inspection ndiyo nzira nhatu dzinonyanya kushandiswa pakuongorora kwepamusoro pekugadzirisa.Kuyedzwa kwepamhepo kunogona kuve kwese static kuyedzwa uye kusimba kuyedzwa.

Global Wei Technology inokupa sumo pfupi kune dzimwe nzira dzekuona:

Chekutanga, manyorerwo ekuona nzira yekuona.

Iyi nzira ine zvishoma zvekupinza uye haidi kuvandudza zvirongwa zvebvunzo, asi inononoka uye inozviisa pasi uye inoda kutarisa nekuona nzvimbo yakayerwa.Nekuda kwekushaikwa kwekutarisa kwekuona, haiwanzo kushandiswa seyo huru welding yemhando yekuongorora inoreva pane yazvino SMT yekugadzirisa mutsara, uye yakawanda yacho inoshandiswa pakugadzirisa uye zvichingodaro.

Chechipiri, nzira yekuona optical.

Nekuderedzwa kwePCBA chip component package saizi uye kuwedzera kwedunhu bhodhi chigamba density, kuongorora kweSMA kuri kuramba kuchioma, kuongorora ziso remaoko hakuna simba, kugadzikana kwayo uye kuvimbika kwakaoma kuzadzisa zvinodiwa zvekugadzira uye kutonga kwemhando, saka kushandiswa kwekutsvaga kwemasimba kunowedzera kukosha.

Shandisa automated optical inspection (AO1) sechombo chekudzikisa kuremara.

Inogona kushandiswa kuwana uye kubvisa zvikanganiso pakutanga kwechigamba chekugadzirisa maitiro kuti uwane yakanaka maitiro ekutonga.AOI inoshandisa masisitimu epamberi ekuona, nzira itsva dzekudyisa mwenje, kukwidziridza uye nzira dzakaoma dzekugadzirisa kuti uwane huwandu hwakaremara hwekubatwa nekumhanya kwekuyedza.

Chinzvimbo cheAOl pamutsara wekugadzira weSMT.Panowanzova nemhando nhatu dzemidziyo yeAOI pamutsetse wekugadzira weSMT, yekutanga iAOI inoiswa pachikirini chinodhinda kuona kukanganisa kwesolder paste, inodaidzwa kuti post-screen printing AOl.

Chechipiri iAOI inoiswa mushure mechigamba kuti ione kukanganiswa kwemudziyo, inonzi post-patch AOl.

Mhando yechitatu yeAOI inoiswa mushure mekuyerera patsva kuti ione kukwidzwa kwemudziyo nekukanganisa kwewelding panguva imwe chete, inonzi post-reflow AOI.
