Ubuningi bomhlangano buphakeme, imikhiqizo ye-elekthronikhi incane ngosayizi nokukhanya ngesisindo, kanye nevolumu nengxenye yezakhi ze-patch kumayelana ne-1/10 yezakhi ze-plug ze-plug kuphela
Ngemuva kokukhethwa okujwayelekile kwe-SMT, umthamo wemikhiqizo ye-elekthronikhi yehliswa ngo-40% kuya ku-60%, futhi isisindo sehliswe ngo-60% kuya ku-80%.
Ukuthembeka okuphezulu nokumelana namandla aqinile. Isilinganiso esiphansi sokuhlasela solder.
Izici ezinhle kakhulu zemvamisa. Inciphise ukuphazamiseka kwe-electromagnetic ne-RF.
Kulula ukuzuza ezenzakalelayo, thuthukisa ukusebenza kahle kokukhiqiza. Yehlisa izindleko nge-30% ~ 50%. Gcina idatha, amandla, imishini, amandla amandla, isikhathi, njll.
Kungani usebenzise i-Surface Mount Amakhono (SMT)?
Imikhiqizo ye-elekthronikhi ifuna ama-miniaturization, kanye nezinto ezihlanganisiwe ze-plug-in ezisetshenzisiwe ngeke zisancishiswe.
Umsebenzi wemikhiqizo ye-elekthronikhi uqedile ngokwengeziwe, futhi okukhethiwe komjikelezo (ic) okukhethiwe akunazo izingxenye ezihlanganisiwe, ikakhulukazi ama-ICS amakhulu, kanye nezinto ezihlanganisiwe ze-ICS
Isisindo somkhiqizo, ezenzakalelayo zokukhiqiza, ifektri kuya kokuphuma okuphezulu kwezindleko, khiqiza imikhiqizo yekhwalithi yokuhlangabezana nezidingo zamakhasimende futhi uqinise ukuncintisana kwemakethe
Ukuthuthukiswa Kwezakhi Ze-elekthronikhi, Ukuthuthukiswa Kwemibuthano Ehlanganisiwe (ICS), ukusetshenziswa okuningi kwedatha ye-semiconductor
Ukuguqulwa kwezobuchwepheshe ngogesi kubalulekile, kujaha inkambiso yomhlaba
Kungani usebenzise inqubo engenakuhlanza emakhono aseMount Surve?
Enqubweni yokukhiqiza, amanzi okungcola ngemuva kokuhlanza umkhiqizo kuletha ukungcoliswa kwekhwalithi yamanzi, umhlaba nezilwane nezitshalo.
Ngaphezu kokuhlanza kwamanzi, sebenzisa izixazululo ze-organic eziqukethe chlorofluorocarbons (CFC & HCFC) Ukuhlanza nakho kudala ukungcola nomonakalo emoyeni nomoya. Insalela ye-ejenti yokuhlanza izodala ukugqwala ebhodini lomshini futhi lithinte kakhulu ikhwalithi yomkhiqizo.
Yehlisa ukusebenza kokuhlanza kanye nezindleko zokulungiswa komshini.
Akukho hlanza kunganciphisa umonakalo odalwe yi-PCBA ngesikhathi sokunyakaza nokuhlanza. Kusekhona ezinye izinto ezingenakuhlanzwa.
Izinsalela ze-Flux zilawulwa futhi zingasetshenziswa ngokuya ngezidingo zokubukeka komkhiqizo ukuvikela ukuhlolwa okubonakalayo kwezimo zokuhlanza.
I-flux eyinsalela ithuthukiswe njalo ngomsebenzi wayo kagesi ukuvikela umkhiqizo oqediwe kusuka ekuvuzeni kukagesi, okuholela kunoma yikuphi ukulimala.
Yiziphi izindlela zokutholwa kwe-SMT patch yesitshalo sokusebenza kwe-SMT Patch?
Ukutholwa ekucushweni kwe-SMT kuyindlela ebaluleke kakhulu yokuqinisekisa ikhwalithi ye-PCBA, izindlela eziphambili zokutholwa zifaka ukutholwa kokutholwa kwencwajana, izici ze-autory advene, izici ezibonakalayo zenqubo ngayinye, izindlela zokutholwa zenqubo ngayinye zihlukile. Endleleni yokutholwa yesitshalo sokucubungula i-SMT Patch, ukutholwa okubonakalayo okwenziwe ngesandla kanye nokuhlolwa kwe-automatooptical kanye nokuhlolwa kwe-X-ray yizindlela ezintathu ezisetshenziswa kakhulu ekuhlolweni kwenqubo yomhlangano. Ukuhlolwa kwe-Intanethi kungaba ukuhlola okuyisisekelo nokuhlolwa okunamandla.
I-Global Wei Technology ikunikeza isingeniso esifushane kwezinye izindlela zokutholwa:
Okokuqala, indlela yokuthola ukubonwa okubonakalayo.
Le ndlela inokokufaka okuncane futhi ayidingi ukuthuthukisa izinhlelo zokuhlola, kepha iyahamba kancane futhi iyabonakala futhi idinga ukuhlola indawo elinganiselwe. Ngenxa yokuntuleka kokuhlola okubukwayo, akuvamile ukusetshenziswa njengoba ukuhlolwa kwekhwalithi ye-welding yekhwalithi enkulu kusho umugqa wamanje wokucubungula i-SMT, futhi iningi lalo lisetshenziselwa kabusha ukuze lisebenze kabusha nokunye.
Indlela yesibili yokuthola.
Ngokuncishiswa kwe-PCBA Chip Content Package usayizi kanye nokwanda kwesibalo se-Patch Patch, ukuhlolwa kwe-SMA kunzima ngokwengeziwe, ukuqinisekiswa kwamehlo okubumbayo akunzima ukubhekana nezidingo zokukhiqiza nokulawulwa kwekhwalithi, ngakho-ke ukusetshenziswa kokutholwa okunamandla kuya ngokuya kubaluleke kakhulu.
Sebenzisa ukuhlolwa okuzenzakalelayo okuzenzakalelayo (AO1) njengethuluzi lokunciphisa amaphutha.
Ingasetshenziswa ukuthola nokuqeda amaphutha kusenesikhathi kwinqubo yokusebenza kwe-patch ukufezekisa inqubo enhle yenqubo. I-AOI isebenzisa amasistimu wokubona okuthuthukile, izindlela zokuphakelwa kwenoveli ukukhanya, ukukhulisa okuphezulu nezindlela eziyinkimbinkimbi zokucubungula izindlela zokuthola amanani aphezulu okuthwebula ukuthwebula ngesivinini esikhulu sokuhlola.
Isikhundla se-AOL entanjeni yokukhiqiza i-SMT. Kunezindlela ezi-3 zemishini ye-AOI emugqeni wokukhiqiza i-SMT, owokuqala yi-AOI ebekwe ekuphrintweni kwesikrini ukuthola iphutha le-solse le-sool, elibizwa ngokuthi yi-AOL yokuphrinta kwesikrini.
Okwesibili yi-AOI ebekwe ngemuva kwesichibi ukuthola amaphutha akhuphukayo edivayisi, ebizwa nge-AOL ye-AOL ye-post-patch.
Uhlobo lwesithathu lwe-AOI lubekwe ngemuva kokukhonjiswa ukuthola amaphutha okufaka amadivaysi kanye namaphutha afanayo ngasikhathi sinye, okubizwa nge-Post-Reflow AOI.
