Ibhodi ye-PCB (i-Printedcircuitboard) yinkxaso yezixhobo ze-elektroniki kunye nomnikezeli wonxibelelwano phakathi kwezixhobo ze-elektroniki kunye nezixhobo zombane. Phantse isisiseko sazo zonke izixhobo ezikrelekrele. Ukongeza kwimisebenzi esisiseko yokulungisa izixhobo ezahlukeneyo ezincinci ze-elektroniki, umsebenzi obaluleke ngakumbi kukubonelela ngonxibelelwano lwezixhobo ze-elektroniki ezingentla.
Zithini izinto ezisetyenziswa kwibhodi yePCB?
Ibhodi yesekethe ye-PCB yenziwe ikakhulu ngephedi yokuwelda, umngxuma odlulayo, umngxuma wokufakela, ucingo, izinto, izihlanganisi, ukuzalisa, umda wombane njalo njalo.
(1) Iphedi: umngxuma wesinyithi osetyenziselwa iiphini zokuwelda zezixhobo.
(2) Imingxuma: kukho isinyithi esidlula kwimingxuma kunye nesingesisinyithi esidlula kwimingxuma, apho isinyithi esidlula kwimingxuma sisetyenziselwa ukudibanisa izikhonkwane zezinto eziphakathi komaleko ngamnye.
(3) Umngxuma wokufaka: usetyenziselwa ukulungisa ibhodi yesekethe.
(4) I-Conductor: ifilimu yobhedu yenethiwekhi yombane esetyenziselwa ukudibanisa iiphini zezinto.
(5) Izihlanganisi: izinto ezisetyenziselwa ukudibanisa iibhodi zesekethe.
(6) Ukuzalisa: ukusetyenziswa kobhedu kwinethiwekhi yocingo lomhlaba kunokunciphisa ngempumelelo ukungasebenzi kakuhle kombane.
(7) Umda wombane: osetyenziselwa ukumisela ubungakanani bebhodi yesekethe, izinto zebhodi azinakudlula umda.
Ibhodi yesekethe ye-PCB ngokwesakhiwo ingahlulwahlulwa ibe yiphaneli enye ye-PCB, iphaneli ephindwe kabini ye-PCB, ibhodi ye-PCB enezitezi ezininzi; Ibhodi eqhelekileyo enezitezi ezininzi inezitezi ezine, ibhodi enezitezi ezintandathu, ibhodi ye-PCB enezitezi ezininzi eyinkimbinkimbi inokufikelela kwiileya ezingaphezu kweshumi.
Okukhona iileya ezininzi zeebhodi ze-PCB, kokukhona ukusebenza kombane kuzinze kwaye kuthembekile, kwaye ixabiso liphezulu. Umahluko weendleko zeephaneli enye nembini awumkhulu. Ukuba akukho mfuneko ikhethekileyo, onke amashishini aya kukhetha ngokukhethekileyo iiphaneli ezimbini. Emva kwayo yonke loo nto, ukusebenza kunye nokuzinza kwephaneli ezimbini kungcono kunokwephaneli enye.
Kwibhodi ye-PCB eneziteya ezininzi, ngoku ishishini lelona bhodi isetyenziswa kakhulu okanye ezine, ezineziteya ezintandathu, ishishini le-elektroniki labathengi elinebhodi ye-pcb ekumgangatho ophezulu lingaphezulu. Nangona iiphaneli ezineziteya ezininzi zineengenelo ezingaphezulu kuneephaneli ezimbini ekusebenzeni, uzinzo, ingxolo kunye nezinye izinto, amashishini amaninzi kunye neenjineli zisakhetha iiphaneli ezimbini ukuze kuqwalaselwe iindleko.
Njengoko izixhobo ezikrelekrele zisiba nzima ngakumbi nangakumbi, kufuneka izixhobo ezingakumbi, nto leyo ekhokelela kwiisekethe ezixineneyo kunye nezixhobo kwi-PCB. Kwangaxeshanye, iimfuno zomgangatho wezihlanganisi zebhodi ye-PCB zamandla aphezulu nazo ziyaphuculwa. Ibhodi ye-PCB encinci ayinakunciphisa kuphela iindleko, kodwa inokwenza lula uyilo lwebhodi ye-PCB, ukuze ilahleko yesiginali yokuhambisa isekethe ibe ncinci.
Isixhumi sebhodi ye-PCB esinombane ophezulu silingana kuphela ne-knuckle, kwaye umqhubi woqhagamshelwano ugqunywe ngesilivere ngobhedu obomvu, nto leyo ephucula kakhulu ukusebenza komthwalo wangoku wesixhumi. Nokuba sincinci sinokuba nomthwalo wamandla aphezulu, okuqinisekisa ukusebenza kakuhle kwesekethe, kunye neendlela ezahlukeneyo zokufakela zinokuhlangabezana neemfuno zokufakela zabathengi abahlukeneyo bebhodi ye-PCB.
I-Amass inobude obahlukeneyo bezihlanganisi zeebhodi zesekethe ze-PCB ezinobukhulu obahlukeneyo, obuhambelana nomgangatho weshishini wobukhulu bephaneli eveziweyo obuyi-1.0-1.6mm ukuqinisekisa ukusetyenziswa okuqhelekileyo kwezixhobo!
