1. Ubungakanani bebhodi engenanto kunye nokumila
Into yokuqala ekufuneka uyiqwalaselePCBuyilo loyilo bubukhulu, imilo kunye nenani leeleya zebhodi engenanto.Ubungakanani bebhodi engenanto idla ngokugqitywa ngubungakanani bemveliso yokugqibela ye-elektroniki, kwaye ubungakanani bendawo bunquma ukuba zonke izinto ezifunekayo ze-elektroniki zingabekwa.Ukuba akunandawo yaneleyo, ungaqwalasela i-multi-layer okanye uyilo lwe-HDI.Ke ngoko, kubalulekile ukuqikelela ubungakanani bebhodi ngaphambi kokuqala uyilo.Eyesibini yimilo yePCB.Kwiimeko ezininzi, zixande, kodwa kukwakho nezinye iimveliso ezifuna ukusetyenziswa kwee-PCB ezinemilo engaqhelekanga, ekwanefuthe elikhulu ekubekweni kwecandelo.Elokugqibela linani leeleya zePCB.Kwelinye icala, i-PCB enamaleko amaninzi isivumela ukuba senze uyilo oluntsonkothileyo kwaye sizise imisebenzi emininzi, kodwa ukongeza umaleko owongezelelweyo kuya kwandisa ixabiso lemveliso, ngoko ke kufuneka kumiselwe kwinqanaba lokuqala loyilo.iileya ezithile.
2. Inkqubo yokuvelisa
Inkqubo yokuvelisa esetyenziselwa ukuvelisa i-PCB yenye ingcamango ebalulekileyo.Iindlela ezahlukeneyo zokuvelisa zizisa imiqobo yoyilo eyahlukeneyo, kubandakanya iindlela zokuhlanganisa iPCB, ekufuneka ziqwalaselwe.Iitekhnoloji zendibano ezahlukeneyo ezifana ne-SMT kunye ne-THT ziya kufuna ukuba uyile i-PCB yakho ngokwahlukileyo.Into ephambili kukuqinisekisa kunye nomvelisi ukuba bayakwazi ukuvelisa ii-PCB ozifunayo kwaye banezakhono kunye nobuchule obufunekayo ukuphumeza uyilo lwakho.
3. Izinto eziphathekayo kunye namacandelo
Ngexesha lenkqubo yoyilo, izinto ezisetyenzisiweyo kunye nokuba amacandelo asekhona kwiimarike kufuneka athathelwe ingqalelo.Ezinye iindawo kunzima ukuzifumana, zidla ixesha kwaye ziyabiza.Kuyacetyiswa ukuba kusetyenziswe ezinye iindawo ezisetyenziswa ngokuqhelekileyo ukutshintshwa.Ke ngoko, umyili wePCB kufuneka abe namava abanzi kunye nolwazi loshishino lwendibano yePCB iphela.UXiaobei unoyilo lwePCB yobuchwephesha Ubuchwephesha bethu bokukhetha ezona mathiriyeli zifanelekileyo kunye namacandelo kwiiprojekthi zabathengi, kunye nokubonelela ngoyilo lwePCB oluthembekileyo ngaphakathi kohlahlo lwabiwo-mali lwabathengi.
4. Ukubekwa kwecandelo
Uyilo lwePCB kufuneka luthathele ingqalelo indlela abekwe ngayo amacandelo.Ukulungelelanisa ngokufanelekileyo iindawo zamacandelo kunokunciphisa inani lamanyathelo endibano afunekayo, ukwandisa ukusebenza kakuhle kunye nokunciphisa iindleko.Umyalelo wethu wokubekwa ocetyiswayo ziziqhagamshelo, iisekethe zamandla, iisekethe zesantya esiphezulu, iisekethe ezibalulekileyo, kwaye ekugqibeleni izinto eziseleyo.Kwakhona, kufuneka siqaphele ukuba ukutshatyalaliswa kobushushu obugqithisileyo kwi-PCB kunokunciphisa ukusebenza.Xa uyila uyilo lwePCB, qwalasela ukuba ngawaphi amacandelo aya kuchitha obona bushushu, gcina amacandelo abalulekileyo kude nezinto ezinobushushu obuphezulu, kwaye ucinge ngokungeza iisinki zobushushu kunye neefeni zokupholisa ukunciphisa ubushushu becandelo.Ukuba kukho izinto ezininzi zokufudumeza, ezi zinto kufuneka zihanjiswe kwiindawo ezahlukeneyo kwaye azikwazi ukugxila kwindawo enye.Kwelinye icala, indlela abekwa kuyo amacandelo nawo kufuneka aqwalaselwe.Ngokuqhelekileyo, amacandelo afanayo acetyiswa ukuba abekwe kwicala elifanayo, eliluncedo ekuphuculeni ukusebenza kakuhle kwe-welding kunye nokunciphisa iimpazamo.Kufuneka kuqatshelwe ukuba inxalenye akufanele ibekwe kwicala le-solder ye-PCB, kodwa kufuneka ibekwe emva kwe-plad ngokusebenzisa inxalenye yomngxuma.
5. Amandla kunye neenqwelomoya zomhlaba
Amandla kunye neenqwelo-moya zomhlaba kufuneka zihlale zigcinwe ngaphakathi kwebhodi, kwaye kufuneka zibekwe phakathi kwaye zilinganiswe, ezisisiseko sesikhokelo soyilo loyilo lwePCB.Ngenxa yokuba olu luyilo lunokuthintela ibhodi ukuba igobe kwaye ibangele ukuba amacandelo aphambuke kwindawo yawo yokuqala.Ukulungelelaniswa okufanelekileyo komhlaba wamandla kunye nomhlaba wokulawula kunokunciphisa ukuphazamiseka kombane ophezulu kwisekethe.Sidinga ukwahlula iiplani zomhlaba kwinqanaba ngalinye lamandla kangangoko kunokwenzeka, kwaye ukuba akunakuphepheka, ubuncinane qiniseka ukuba zisekupheleni kwendlela yamandla.
6. IMbonakaliso yeMbonakaliso kunye neMiba yeRF
Umgangatho woyilo loyilo lwePCB ukwamisela imfezeko yomqondiso webhodi yesekethe, nokuba iya kuxhomekeka kuphazamiseko lombane kunye neminye imiba.Ukunqanda iingxaki zomqondiso, uyilo kufuneka luthintele umkhondo ohamba ngokuhambelanayo omnye komnye, kuba umkhondo ohambelanayo uya kudala i-crosstalk eninzi kwaye ibangele iingxaki ezahlukeneyo.Kwaye ukuba umkhondo kufuneka uwele omnye nomnye, kufuneka uwele kwii-angles ezifanelekileyo, ezinokunciphisa i-capacitance kunye ne-inductance yokubambisana phakathi kwemigca.Kwakhona, ukuba amacandelo anemveliso ye-electromagnetic ephezulu ayifunwa, kuyacetyiswa ukuba kusetyenziswe izinto ze-semiconductor ezivelisa ukukhutshwa kwe-electromagnetic ephantsi, ekwanegalelo kwimfezeko yomqondiso.
