In Umatshini wokufaka i-SMDinkqubo yombono singakwazi ngokuchanekileyo ngakumbi amacandelo yangoku, iibhodi zesekethe okanyeUmbhobho wokufunxa we-SMTisikhundla, ukuthembela kwinkqubo yokuqaphela okubonakalayo sinokubonelela ngokubekwa okuchanekileyo kumatshini wokubeka emva koko uyaqonda ukuba le nkqubo yenziwe njani?
1. Kukho ikhamera yentloko ngaphezu kwe-mounter, ngokuqhelekileyo isebenzisa iteknoloji ye-sensor yomgca, kwinkqubo yokuthabatha kunye nokuhamba ngentloko ye-mounter inokubona amacandelo kwindawo echongiweyo.Inokuphucula ukuchaneka kokubekwa kunye nokusebenza kakuhle.Ngokuqhelekileyo, inkqubo yenziwe ngeemodyuli ezimbini: enye yimodyuli yomthombo wokukhanya eyenziwe ngumthombo wokukhanya kunye ne-lens.Ilensi yomthombo wokukhanya ibandakanya imodyuli yokuhambisa ukukhanya.
2. Kukho ikhamera yokujonga phezulu ngaphantsi kwe-mounter, sinokuyisebenzisa ukufumanisa indawo yecandelo, xa ikhamera yenkqubo yokuchonga ifakwe phakathi kwendawo yokubeka kunye nendawo yokufakela, ngoko sinokuqhuba ukufunyanwa kwevidiyo kunye nokusebenza xa usebenzisa. intloko yevidiyo, ngaloo ndlela yenza mfutshane ixesha lokufakela isixhosi.
3. Inkqubo yokulungelelaniswa kweLaser sinokusebenzisa le nkqubo yobungakanani kunye nokumila kwamacandelo alinganisiweyo kumatshini wokunyuka.Inzuzo kukuba ulungelelwaniso lukhawuleza kwaye luchanekile, kodwa i-disadvantage kukuba ayinakwenza uhlolo lwepini kwiikhonkwane kunye namacandelo anezikhonkwane eziqinileyo.
Umbono weNkqubo yeI-NeoDen4 desktop pick kwaye ubeke umatshini
INeoDenI-4 ibonisa ukuchaneka okuphezulu, inkqubo yombono weekhamera ezimbini.Iikhamera zenziwe yi-Micron Technology kwaye zilungelelaniswe ngokuchanekileyo kwimibhobho zisebenzisa uqwalaselo olulodwa oludibeneyo / isicelo sokusebenza esilayisha kumbane.
Ikhamera ejonge ezantsi:
Entloko isetyenziselwa indawo echanekileyo yezondla kunye neendawo zokubeka zePCB.Ukuhlaikhamera ejongayo ikwaqinisekisa ukubekwa kwebhodi ngokufanelekileyo (kwaye ibuyekeze indawo encinci yebhodiizinto ezingachanekanga) ngokulungelelanisa imilomo ngokuzenzekelayo kwiifiducials ezininzi ebhodini phambi kokuba kuqaliswe imisebenzi yokwenyani yokukhetha nendawo.Nje ukuba ulungelelwaniso lusekiwe, iimotor zesemi-closed-loop stepper ziyakwazi ukuphinda ezi ndawo ukuya ku-20µm ukuchaneka ngaphandle kwesidingo esingakumbi sale khamera.
Ikhamera ejonge phezulu:
Ibekwe kwicala lasekunene lomatshini.Xa yenziwe yasebenza, le khamera iqinisekisa kuqala ukuba icandelo lincanyathiselwe kumbhobho ofanelekileyo.Ukuba ikhamera ibona ukungabikho kwecandelo, umatshini uya kwenza ukuya kuthi ga kwiinzame ezimbini ezongezelelweyo zokukhetha icandelo ngaphambi kokuba ubuze umsebenzisi imiyalelo eyongezelelweyo.Emva kokuba icandelo liqinisekisiwe njenge "lichongiwe", ikhamera iqinisekisa indawo yayo xa ithelekiswa nombhobho.Ngenxa yokuba ii-SMD zincinci kwaye zilula, kwaye zibanjwe kuphela ngokukhululekileyo kwipakethe yazo, kunokubakho ukuhluka okukhulu kwindawo yokwenene yecandelo xa ifika kwindawo "yokukhetha" kwaye iphakanyiswe ngumlomo.Inkqubo yombono ibala umahluko phakathi kweyona ndawo ifanelekileyo kunye nendawo eyiyo (zombini i-XY kunye nokujikeleza), kwaye emva koko ilungise nayiphi na impazamo phambi kokubeka icandelo ngokuchanekileyo.Ngenxa yokuba inkqubo yombono isoloko ilungisa iimpazamo ezincinane nakwindawo yesi-2 kumbhobho, iikhomponenti zepitch entle kakhulu (ukuhla ukuya ku-0201) zinokubekwa ngokuchaneka okuphinda-phindayo xa kuchongiwe ulungelelwaniso oluchanekileyo.Ngolu kuqonda okusisiseko, le mifanekiso ilandelayo ityhila amacandelo asisiseko e-Neoden4.
