Abavelisi bePCB babeke ikhonkco leshishini leMini le-LED
I-Apple malunga nokuphehlelela iimveliso ze-Mini LED backlight, kwaye abavelisi bohlobo lweTV baye bazisa ngokulandelelana iMini LED.Ngaphambili, abanye abavelisi baphehlelele iincwadana zeMini ze-LED, kwaye amathuba amashishini anxulumeneyo athe avela ngokuthe ngcembe.Umntu osemthethweni ulindele ukuba iifektri zePCB ezifana...Funda ngokugqithisileyo -
Ukwazi oku, ngaba uyafuna ukusebenzisa i-PCB ephelelwe lixesha?
Eli nqaku ikakhulu lazisa iingozi ezintathu zokusebenzisa i-PCB ephelelwe lixesha.01 I-PCB ephelelwe lixesha inokubangela i-pad oxidation yomphezulu Ukwenziwa kwe-oxidation yeephedi ze-soldering kuya kubangela ukusoda okulambathayo, okunokuthi ekugqibeleni kukhokelele kukusilela kokusebenza okanye umngcipheko wokuyeka isikolo.Unyango lomphezulu olwahlukeneyo lweebhodi zesekethe w...Funda ngokugqithisileyo -
Kutheni iPCB ilahla ubhedu?
A. Imiba yenkqubo yomzi-mveliso we-PCB 1. Ukukrolwa ngokugqithisileyo kwefoyile yobhedu Ifoyile yobhedu ye-electrolytic esetyenziswa kwimarike ngokuqhelekileyo iba yigalvanized enecala elinye (eyaziwa ngokuba yi-ashing foil) kunye nokufakwa kwecala elinye lobhedu (ekwaziwa ngokuba yifoyile ebomvu).Ifoyile yobhedu eqhelekileyo idla ngokuba yikopa efakwe igalvanized...Funda ngokugqithisileyo -
Indlela yokunciphisa imingcipheko yoyilo lwePCB?
Ngexesha lenkqubo yoyilo lwePCB, ukuba imingcipheko enokwenzeka inokuqikelelwa kwangaphambili kwaye ithintelwe kwangaphambili, izinga lempumelelo loyilo lwePCB liya kuphuculwa kakhulu.Iinkampani ezininzi ziya kuba nesalathisi sempumelelo yoyilo lwePCB ibhodi enye xa kuhlolwa iiprojekthi.Isitshixo sokuphucula impumelelo...Funda ngokugqithisileyo -
Izakhono ze-SMT 丨 imigaqo yokubekwa kwecandelo
Kuyilo lwePCB, uyilo lwamacandelo yenye yekhonkco elibalulekileyo.Kwiinjineli ezininzi ze-PCB, indlela yokubeka amacandelo ngokufanelekileyo nangempumelelo inemigangatho yayo.Sishwankathele izakhono zoyilo, malunga noku kulandelayo 10 Uyilo lwamacandelo e-elektroniki kufuneka lulandelwe...Funda ngokugqithisileyo -
Yeyiphi indima edlalwa zizo “pads ezikhethekileyo” kwiPCB?
1. Iphedi yeentyatyambo zePlum.I-1: Umngxuma wokulungisa kufuneka ungabi-metalized.Ngexesha le-wave soldering, ukuba umngxuma wokulungisa ngumgodi owenziwe ngesinyithi, i-tin iya kuwuvala umngxuma ngexesha lokuphinda kufakwe i-solder.2. Ukulungisa imingxunya ekhwelayo njenge pads quincunx ngokuqhelekileyo isetyenziselwa ukunyuswa komngxuma womnatha we-GND, kuba ngokubanzi...Funda ngokugqithisileyo -
Kutheni uyilo lwe-PCB lulawula ngokubanzi i-50 ohm impedance?
Kwinkqubo yoyilo lwe-PCB, phambi komzila, sibeka ngokubanzi izinto esifuna ukuyila, kwaye sibale i-impedance ngokusekelwe kubunzima, i-substrate, inani leeleya kunye nolunye ulwazi.Emva kokubala, umxholo olandelayo unokufumaneka ngokubanzi.Njengoko kubonakala ...Funda ngokugqithisileyo -
Uwubuyisela njani umva umzobo wesicwangciso sebhodi yokukopa yePCB
PCB ikopi ibhodi, ishishini lidla ngokubizwa ngokuba ibhodi yesekethe ikopi ibhodi, ibhodi yesekethe clone, ikopi yebhodi yesekethe, PCB clone, PCB uyilo reverse okanye PCB reverse uphuhliso.Oko kukuthi, kwisiseko sokuba kukho izinto ezibonakalayo zeemveliso ze-elektroniki kunye neebhodi zeesekethe, uhlahlelo oluhlaziyiweyo lwe ...Funda ngokugqithisileyo -
Uhlalutyo lwezizathu ezithathu eziphambili zokulahlwa kwePCB
I-PCB yocingo yobhedu iyawa (ekwabizwa ngokuba kukulahla ubhedu).Iifektri zePCB zonke zithi yingxaki yelaminate kwaye ifuna ukuba iifektri zabo zemveliso zithwale ilahleko embi.1.
