Eli nqaku liza kwabelana ngobuchule obufana nokulungelelaniswa, ukulungisa, kunye novavanyo lwebhodi yokulwa kwimisebenzi yovavanyo olubhabhayo lwereferensi kuphela.
1. I-Counterpoint
Into yokuqala yokuthetha ngayo kukukhethwa kwee-counterpoints. Ngokuqhelekileyo, imingxuma emibini kuphela ye-diagonal kufuneka ithathwe njengee-counterpoints. ?) Ungayihoyi i-IC. Inzuzo yale nto kukuba kukho amanqaku amancinci okulungelelaniswa, kwaye ixesha elincinci lichithwa ekulungelelaniseni. Ngokubanzi, i-etching ihlala ine-undercuts, ngoko ke ayichanekanga kakhulu ukukhetha iipads zamanqaku olungelelwaniso. Ukuba kukho iisekethe ezininzi ezivulekileyo, akukho mfuneko yokuba uyeke ngokukhawuleza, kwaye uyeke xa uvavanyo lwesekethe oluvulekileyo lugqityiwe kwaye uqalise uvavanyo olufutshane lwesekethe, kuba unako ukujonga iimpazamo zesiphaluka ezivulekileyo ngeli xesha. yongeza indawo ekujoliswe kuyo ngokwendawo yempazamo exeliweyo.
Makhe sithethe ngolungelelwaniso lwezandla kwakhona. Ukuthetha ngokuthe ngqo, imingxuma ayikho embindini weepads, ngoko xa ubeka indawo, kufuneka amachaphaza abekwe embindini weepads kangangoko kunokwenzeka, okanye uzame ukuhambelana nemingxuma yangempela? Ngokubanzi ukuba kukho amanqaku amaninzi aza kuvavanywa Umngxuma, khetha umva. Ukuba ininzi i-IC, ngakumbi xa i-IC ixhomekeke kwisekethe evulekileyo yobuxoki, kufuneka ubeke umngxuma wokulungelelanisa phakathi kwepadi.
Okwesibini, isakhelo esisisigxina
Isakhelo esisisigxina sisibiyeli sovavanyo olusisigxina. Idatha eyakhiweyo imelwe ziibhokisi ezimbini. Isakhelo sangaphandle sisakhelo. Kwibhodi enjalo, ubukhulu obunikwe ngumatshini bunokusetyenziswa ngokuthe ngqo. Kwidatha ngaphandle kwesakhelo, Imelwe yibhokisi. Singasebenzisa umyalelo webhodi yokubonisa (eya kusetyenziswa xa ujonge isalathiso sebhodi) ukubona ukuba yeyiphi ipadi evavanyiweyo kumda okufutshane. Thelekisa ibhodi yokwenyani ukuze ubone umgama wayo ukusuka emphethweni Ingakanani esetyenziselwa ukuhlawula.
3. Ukuwela
Kwibhodi yokupakisha, enye ekhethiweyo inokuvavanywa. Singasebenzisa lo msebenzi ukuqonda uvavanyo lwebhodi yokupakisha apho umgama phakathi kwepadi kunye nomphetho webhodi umncinci kakhulu ukuvavanya. Indlela yokuvala iipads ezingenakubanjelwa kwi-tray. Uvavanyo olulodwa lugqitywe, kwaye emva kovavanyo, i-tray ifakwe kwi-plate ehleliweyo yovavanyo olulodwa, kwaye ibhodi engazange ihlolwe okokugqibela ikhethiwe, ukwenzela ukuba ibhodi yonke ihlolwe ngeemvavanyo ezi-2. Ngoko ke, kufuneka sisebenzise ngokuguquguqukayo imisebenzi ebonelelwe sisixhobo ukuzalisekisa iimfuno ezikhethekileyo.
Okwesine, i-warpage
Ubungakanani kwicala elinye likhulu kakhulu, ngakumbi xa ubungakanani kwelinye icala buncinci ngokwentelekiso, ibhodi iya kurhwaphiliza ngokwendalo (okubangelwa ngumxhuzulane) xa ibekwe kumatshini wovavanyo, kwaye umatshini wethu ophaphazelayo unesakhiwo esincinci Ingxaki encinci, ubungakanani kwindlela ye-X inkulu, kodwa i-pallet enye kuphela ibekwe, kwaye kwindlela ye-Y enobungakanani obuncinci, iipalethi ezintathu zingabekwa. Ngoko ke, umatshini ukhetha ulwalathiso olude lwebhodi ukuba lulinganiswe Xa lubekwe kwindlela ye-X yomatshini, kukulungele ukuyilungisa ngesandla, ukujikeleza ibhodi ye-90 degrees, kwaye ubeke ulwalathiso lwalo olude kwi-Y direction, enokusombulula ingxaki ye-warpage yebhodi kuvavanyo ukuya kumlinganiselo othile. (Olu hlengahlengiso kufuneka lusingathwe kwi-DPS).
