Weiwenxin PCBworld] Kuphando lweteknoloji ye-PCB ebuyela umva, umgaqo wokutyhala umva ubhekisa ekutyhaleni umva ngokutsho komzobo woxwebhu lwePCB okanye uzobe ngokuthe ngqo umzobo wesekethe yePCB ngokweyona mveliso, ejolise ekuchazeni umgaqo kunye nemeko yokusebenza yesekethe. ibhodi.Ngaphezu koko, lo mzobo wesiphaluka usetyenziselwa ukuhlalutya iimpawu zokusebenza zemveliso ngokwayo.Kuyilo lwangaphambili, uphuhliso lwemveliso jikelele kufuneka kuqala luqhube uyilo lwesicwangciso, emva koko luqhube uyilo lwePCB ngokwesicwangciso.
Nokuba isetyenziselwa ukuhlalutya imigaqo yebhodi yesekethe kunye neempawu zokusebenza kwemveliso kuphando olubuyela umva, okanye iphinda isetyenziswe njengesiseko kunye nesiseko soyilo lwePCB kuyilo lwangaphambili, iischematics zePCB zinendima ekhethekileyo.Ke, ungawubuyisela njani umva umzobo wesicwangciso sePCB esekwe kwidayagram yoxwebhu okanye eyona nto?Zeziphi iinkcukacha ekufuneka zinikwe ingqwalasela ngexesha lenkqubo yokubala umva?
Ulwahlulo olufanelekileyo lweendawo zokusebenza
01
Xa kusenziwa uyilo olungemva lomzobo weskimu sebhodi yesekethe yePCB elungileyo, ulwahlulo olufanelekileyo lweendawo ezisebenzayo lunokunceda iinjineli zinciphise iingxaki ezingeyomfuneko kwaye ziphucule ukusebenza kakuhle komzobo.Ngokuqhelekileyo, amacandelo anomsebenzi ofanayo kwibhodi yePCB acwangciswe ngendlela egxininiswe, kwaye ulwahlulo lweendawo ngomsebenzi lunokuba nesiseko esifanelekileyo nesichanekileyo xa uguqula umzobo weskimu.
Nangona kunjalo, ulwahlulo lwalo mmandla wokusebenza alunanjongo.Ifuna ukuba iinjineli zibe nokuqonda okuthile kolwazi olunxulumene nesekethe ye-elektroniki.Okokuqala, fumana i-core component kwiyunithi ethile esebenzayo, kwaye ngoko ngokuhambelana noxhumo lwe-wiring, unokufumana amanye amacandelo eyunithi efanayo yokusebenza kwindlela yokwenza ulwahlulo olusebenzayo.Ukwenziwa kwezahlulo ezisebenzayo sisiseko somzobo weskim.Ukongeza, kule nkqubo, ungalibali ukusebenzisa iinombolo ze-serial zamacandelo kwibhodi yesekethe ngobuchule, banokukunceda ukwahlula imisebenzi ngokukhawuleza.
Yahlula ngokuchanekileyo imigca kwaye uzobe iingcingo ngokufanelekileyo
02
Ngokwahlula phakathi kweengcingo zomhlaba, iingcingo zamandla, kunye neengcingo zesignali, iinjineli nazo kufuneka zibe nolwazi olufanelekileyo lonikezelo lwamandla, ulwazi loqhagamshelwano lwesekethe, ulwazi lwe-wiring yePCB, njalo njalo.Ukwahlula le migca kunokuhlalutya malunga nokudibanisa kwamacandelo, ububanzi befoyile yobhedu yomgca, kunye neempawu zemveliso ye-elektroniki ngokwayo.
Kumzobo we-wiring, ukwenzela ukuba ugweme ukuwela kunye nokunyanzeliswa kwemigca, inani elikhulu leempawu zokumisa zingasetyenziselwa umgca womhlaba.Imigca eyahlukeneyo ingasebenzisa imibala eyahlukeneyo kunye nemigca eyahlukeneyo ukuqinisekisa ukuba icacile kwaye iyabonakala.Kumacandelo ahlukeneyo, iimpawu ezikhethekileyo zingasetyenziswa, okanye nokuba Zoba iisekethe zeeyunithi ngokwahlukileyo kwaye uzidibanise ekugqibeleni.
Fumana iindawo ezifanelekileyo zereferensi
03
Eli candelo lesalathiso linokuthiwa licandelo eliphambili elisetyenziswe ekuqaleni komzobo weskim.Emva kokuba inxalenye yereferensi inqunywe, inxalenye yereferensi izotywa ngokwezikhonkwane zala macandelo ereferensi, anokuqinisekisa ukuchaneka komzobo weskimu ukuya kumlinganiselo omkhulu.
Kwiinjineli, ukumiselwa kweengxenye zereferensi akuyona into enzima kakhulu.Kwiimeko eziqhelekileyo, amacandelo adlala indima enkulu kwisekethe anokukhethwa njengeenxalenye zereferensi.Ngokuqhelekileyo zikhulu ngobukhulu kwaye zinezikhonkwane ezininzi, ezilungele ukuzoba.Ezinjengeesekethe ezihlanganisiweyo, ii-transformers, ii-transistors, njl. njl., zonke zinokusetyenziswa njengamacandelo afanelekileyo okukhangela.
Lawula isakhelo esisisiseko kwaye ufunde kwimizobo yeskimu efanayo
04
Ukwakhiwa kwesakhelo sesekethe ye-elektroniki esisiseko kunye neendlela zokuzoba, iinjineli kufuneka zibe nobuchule, kungekhona nje ukukwazi ukuzoba ngokuthe ngqo ezinye iisekethe ezilula kunye neklasikhi zeeyunithi, kodwa kunye nokwenza isakhelo esipheleleyo seesekethe ze-elektroniki.
Kwelinye icala, sukuyihoya into yokuba uhlobo olufanayo lweemveliso ze-elektroniki zinento efanayo kwimizobo yeskimu.Iinjineli zinokusebenzisa ukuqokelelwa kwamava kwaye zifunde ngokupheleleyo kwimizobo yesekethe efanayo ukubuyisela umva imizobo yeskimu yeemveliso ezintsha.
Jonga kwaye ulungiselele
05
Emva kokuba umzobo weskim ugqityiwe, uyilo olungasemva lwe-PCB schematic lunokuthiwa lugqitywe emva kovavanyo kunye nokuqinisekiswa.Ixabiso legama lamacandelo anovakalelo kwiparamitha zonikezelo lwe-PCB kufuneka lijongwe kwaye lilungiswe.Ngokomzobo wefayile ye-PCB, umzobo weskim uyathelekiswa kwaye uhlalutywe ukuqinisekisa ukuba umzobo woyilo uhambelana ngokupheleleyo nomzobo wefayile.
