Iinjineli zePCB zihlala zidibana nemiba eyahlukeneyo yokhuseleko xa zisenza uyilo lwePCB.Ngokwesiqhelo ezi mfuno zokubeka izithuba zohlulwe zibe ziindidi ezimbini, enye yeyokucoceka kokhuseleko lombane, ize enye ibe yimvume yokhuseleko engeyiyo yombane.Ke, zithini iimfuno zezithuba zokuyila iibhodi zesekethe zePCB?
1. Umgama wokhuseleko lombane
1. Isithuba phakathi kweengcingo: ubuncinci besithuba somgca kumgca ukuya kumgca, kwaye isithuba somgca ukuya kwiphedi kufuneka singabi ngaphantsi kwe-4MIL.Ukusuka kwindawo yokujonga imveliso, ngokuqinisekileyo, inkulu ingcono ukuba kunokwenzeka.I-10MIL eqhelekileyo ixhaphake kakhulu.
2. Ukuvula i-pad kunye nobubanzi be-pad: Ngokomenzi we-PCB, ukuba i-pad aperture igrunjwa ngoomatshini, ubuncinane akufanele kube ngaphantsi kwe-0.2mm;ukuba i-laser drilling isetyenzisiwe, ubuncinci akufanele bube ngaphantsi kwe-4mil.Ukunyamezela kwe-aperture kuhluke kancinci kuxhomekeke kwipleyiti, ngokubanzi kunokulawulwa ngaphakathi kwe-0.05mm;ubuncinane bobubanzi bomhlaba kufuneka bungabi ngaphantsi kwe-0.2mm.
3. Umgama phakathi kwe-pad kunye ne-pad: Ngokutsho kwamandla okusebenza omenzi we-PCB, umgama akufanele ube ngaphantsi kwe-0.2MM.
4. Umgama phakathi kwephepha lobhedu kunye nomphetho webhodi: ngokukhethekileyo ungabi ngaphantsi kwe-0.3mm.Ukuba yindawo enkulu yobhedu, ngokuqhelekileyo kukho umgama orhoxisiweyo ukusuka kumda webhodi, ngokuqhelekileyo umiselwe kwi-20mil.
2. Umgama wokhuseleko ongekho ngombane
1. Ububanzi, ubude kunye nesithuba soonobumba: Abalinganiswa kwisikrini sesilika basebenzisa amaxabiso aqhelekileyo anjenge-5/30, 6/36 MIL, njl.
2. Umgama ukusuka kwisikrini sesilika ukuya kwi-pad: isikrini sesilika asivumelekanga ukuba sibe kwi-pad.Ngenxa yokuba ukuba isikrini sesilika sigqunywe ngepadi, isikrini sesilika asiyi kufakwa kwitoti xa sifakwe, okuya kuchaphazela ukubekwa kwecandelo.Ngokuqhelekileyo kuyafuneka ukuba ugcine isithuba esisi-8mil.Ukuba indawo yezinye iibhodi zePCB isondele kakhulu, isithuba se-4MIL siyamkeleka.Ukuba isikrini sesilika sivala ngempazamo ipad ngexesha loyilo, inxalenye yesikrini sesilika eshiywe kwi-pad iya kususwa ngokuzenzekelayo ngexesha lokwenziwa ukuqinisekisa ukuba i-pad ifakwe.
3. Ubude be-3D kunye nesithuba esithe tye kwisakhiwo soomatshini: Xa ufaka izinto kwi-PCB, qwalasela ukuba isalathiso esithe tye kunye nokuphakama kwendawo kuya kungquzulana nezinye izakhiwo zoomatshini.Ngoko ke, xa kuyilwa, kuyimfuneko ukuqwalasela ngokupheleleyo ukulungelelaniswa kwesakhiwo sendawo phakathi kwamacandelo, kwaye phakathi kwe-PCB egqityiweyo kunye neqokobhe lemveliso, kwaye ugcine umgama okhuselekileyo wento nganye ekujoliswe kuyo.
Ezi zingentla zezinye zeemfuno zezithuba ekufuneka zihlangatyezwe xa kuyilwa iibhodi zeesekethe zePCB.Uyazi yonke into?
