Ibhodi ye-PCB (i-Printedcircuitboard) liqumrhu elixhasayo lamacandelo e-elektroniki kunye nomboneleli woqhagamshelo phakathi kwezinto zombane kunye namalungu ombane.Phantse iziseko zazo zonke izixhobo ezikrelekrele.Ukongeza kwimisebenzi esisiseko yokulungisa amacandelo amancinci ahlukeneyo e-elektroniki, owona msebenzi ubaluleke kakhulu kukubonelela ngoqhagamshelwano lwamacandelo e-elektroniki angentla.
Ngawaphi amacandelo ebhodi yePCB?
Ibhodi yesekethe PCB ikakhulu iqulunqwe pad welding, ngokusebenzisa umngxuma, umngxuma ukukhwela, ucingo, amacandelo, izihlanganisi, ukuzaliswa, umda wombane njalo njalo.
(1) I-Pad: umngxuma wesinyithi osetyenziselwa ukuwelda izikhonkwane zamacandelo.
2
(3) Umngxuma wokunyuka: usetyenziselwa ukulungisa ibhodi yesekethe.
(4) I-Conductor: ifilimu yobhedu yomnatha wombane esetyenziselwa ukudibanisa izikhonkwane zamacandelo.
(5) Izixhumi: amacandelo asetyenziselwa ukudibanisa iibhodi zeesekethe.
(6) Ukuzaliswa: isicelo sobhedu kwinethiwekhi yocingo lomhlaba sinokunciphisa ngempumelelo i-impedance.
(7) Umda wombane: usetyenziselwa ukugqiba ubungakanani bebhodi yesekethe, amacandelo ebhodi akanako ukudlula umda.
Ibhodi yesekethe yePCB ngokwesakhiwo inokwahlulwa ibe yiphaneli eyodwa yePCB, iphaneli yePCB kabini, ibhodi yePCB yemultilayer;Ibhodi ye-multilayer eqhelekileyo ine, ibhodi ye-maleko emithandathu, ibhodi eyinkimbinkimbi ye-pcb ye-multilayer inokufikelela kumaleko angaphezu kweshumi.
I umaleko ngakumbi iibhodi PCB, kokukhona uzinzile kwaye ethembekileyo ukusebenza kombane, kwaye ixabiso eliphezulu.Umahluko weendleko zeepaneli ezingatshatanga kunye nezibini azinkulu.Ukuba akukho mfuneko ikhethekileyo, onke amashishini aya kukhetha iiphaneli eziphindwe kabini.Emva kwayo yonke loo nto, ukusebenza kunye nokuzinza kwepaneli ezimbini kungcono kunokwephaneli enye.
In PCB ibhodi multilayer, ngoku ishishini yeyona isetyenziswa kakhulu okanye ezine, ibhodi umaleko ezintandathu, abathengi electronics ishishini kunye nebhodi pcb kwinqanaba eliphezulu ngakumbi.Nangona iipaneli zamalayile amaninzi zineengenelo ezininzi kuneepaneli ezimbini ekusebenzeni, uzinzo, ingxolo kunye neminye imiba, amashishini amaninzi kunye neenjineli zisakhetha iiphaneli ezimbini zoqwalaselo lweendleko.
Njengoko izixhobo ezikrelekrele ziya zisiba nzima ngakumbi nangakumbi, ngakumbi nangakumbi izincedisi ziyafuneka, nto leyo ekhokelela kwiisekethe ezixineneyo kunye nezincedisi kwiPCB.Kwangaxeshanye, iimfuno zomgangatho ophezulu zangoku izihlanganisi ibhodi PCB nazo ziphuculwe.Ibhodi encinci yePCB ayikwazi ukunciphisa iindleko kuphela, kodwa inokwenza lula ukuyila kwebhodi ye-PCB, ukuze ilahleko yokuhanjiswa kwesekethe incinci.
I-Amass high-current PCB ibhodi isidibanisi ubukhulu kuphela knuckle, kwaye umqhubi zoqhagamshelwano isilivere etyatyekwe ngobhedu obomvu, nto leyo iphucula kakhulu ukusebenza ngoku ethwele isinxibelelanisi.Nokuba ubungakanani obuncinci bunokuba nomthwalo ophezulu wangoku, ukuqinisekisa ukusebenza kakuhle kwesekethe, kunye neendlela zofakelo ezahlukeneyo zinokuhlangabezana neemfuno zofakelo lwabathengi abahlukeneyo bebhodi yePCB.
I-Amass inobude obahlukeneyo bokudibanisa kwiibhodi zesekethe ze-PCB ezinobunzima obahlukeneyo, obuhambelana nomgangatho woshishino wobukhulu bephaneli eveziweyo ye-1.0-1.6mm ukuqinisekisa ukusetyenziswa okuqhelekileyo kwezixhobo!
