Ungalibona njani inani le-PCB
Kuba iindawo ezahlukeneyo ze-PCB zidibene ngokuqinileyo, ngokubanzi azikho lula ukubona le nombolo, kodwa ukuba uyayigcina ngononophelo iBhodi iBhodi, unokuyihlula.
Ngononophelo, siya kufumanisa ukuba kukho enye okanye ii-faces zezinto ezimhlophe phakathi kwePCB. Ngapha koko, oku kukuncamathela umaleko phakathi kweendawo zokuqinisekisa ukuba aziyi kubakho ngxaki zimfutshane zikuyo phakathi kweendawo ezahlukeneyo zePCB.
Kuyaqondakala ukuba iibhodi ze-PCB zePCB ezininzi zisebenzisa iiplanga ezingatshatanga ezingatshatanga, kunye nomaleko we-wiring wiring ibekwe phakathi komaleko ngamnye kwaye icinezelwe kunye. Inani leendawo zebhodi ye-PCB zibonisa ukuba zingaphi iingxwaba. Ukuzimela kwe-wiring wiring, kunye ne-suble thermating phakathi kwezingqengqelelo zibe yindawo enomdla kuthi yokugweba inani leendawo ze-PCB.
Indlela yeSikhokelo seSikhokelo sendlela isebenzisa "isikhokelo soMkhosi weSikhokelo" kwi-PCB ukubonisa inani lemigca yePCB. Umgaqo kuphela ubangelwa yitekhnoloji ye-proteract esetyenziswe kuqhagamshelo lwesekethe lwePCB yeZilayidi. Ukuba sifuna ukubona ukuba zingaphi ii-PCB, singakwazi ukwahlula ngokujonga i-Hine Hobes.on i-PCB esecaleni kweBhodi, ke kufuneka iqhubekeke kwelinye icala, ke imingxunya yePilot iya kungena kwi-PCB IBhodi, ukuze sibone ukuba izikhonkwane zelungu zithengisiwe kwelinye icala.
Umzekelo, ukuba iBhodi isebenzisa iBhodi ye-4-Wiked, kuya kufuneka ukuba uzobe iingcingo kwi-theirs yokuqala neyesine (umaleko womqondiso). Ezinye iindawo zinezinye ukusebenzisa (ungqimba lomhlaba kunye nomatshini). Beka umaleko womqondiso kwicandelo lamandla kunye nenjongo yalamacala amabini ongqukuva komhlaba kukuthintela ukuphazamiseka kunye nokwenza lula ukulungiswa komgca womqondiso.
Ukuba kukho amanye amakhamathi eBhodi avela kwicala elingaphezulu lebhodi ye-PCB kodwa akanakufumaneka kwicala elingasemva, i-EDA365 iForum ye-Elektroniki ikholelwa ukuba i-6/8 yeBhodi ye-Waker. Ukuba ngokufanayo nemingxunya inokufumaneka kumacala omabini e-PCB, ngokwendalo iya kuba yibhodi ye-4-Fider.
Nangona kunjalo, uninzi lwabavelisi bekhadibhodi ngoku basebenzisa enye indlela yokuhamba, enokuqhagamshela eminye yemigca, kwaye basebenzise i-vias vias kunye ne-vias eyimfama kwi-vias. Imingxunya engaboniyo kufuneka idibanise iindawo ezininzi zePCB yangaphakathi kwiPCB engaphezulu ngaphandle kokungena kwiBhodi yeSiphaluka.
U-Vias wangcwatywa uyaqhagamshela kwi-PCB yangaphakathi, ukuze bangabonakali kumphezulu. Kuba umngxunya ongaboniyo akufuneki ukuba ungene kwi-PCB yonke, ukuba ngamajelo amathandathu okanye ngaphezulu, jonga iBhodi ejonge umthombo wokukhanya, kwaye ukukhanya akuyi kudlula. Ke yayikho intetho ethandwa kakhulu ngaphambili: ukugweba amacala amane kunye ne-biede yesithandathu okanye ngaphezulu kwe-PCBS nokuba i-vias ivuza ukukhanya.
Kukho izizathu zendlela, kodwa ayisebenzi. IForum ye-elektroniki ikholelwa ukuba le ndlela inokusetyenziswa kuphela njengendlela yesalathiso.

Indlela yokuqokelela
Ukuba sichanekile, le ayisiyondlela, kodwa amava. Kodwa le yinto esicinga ukuba ichanekile. Singaligweba inani leendawo ze-PCB malunga nokulandelwa kweebhodi zePCB zoluntu kunye nendawo yamacandelo. Kuba kumzi mveliso we-Hardwar otshintsha ngokukhawuleza, akukho bathengi abaninzi abakwaziyo ukuhlengahlengisa i-PCBS.
Umzekelo, kwiminyaka embalwa eyadlulayo, inani elikhulu lamakhadi emizobo angama-950 ama-950 emizobo asetyenzisiweyo ngee-PCB ze-6-feble. Ukuba ulumkile, unokuthelekisa indlela eyahluke ngayo ukusuka kwi-9600pro okanye i-9600xt. Shiya nje izinto ezithile, kwaye ugcine ukuphakama okufanayo kwi-PCB.
Ngeminyaka yoo-1990s yenkulungwane edluleyo, kwabakho intetho ebanzi ngelo xesha: inani lezixhobo ze-PCB zinokubonwa ngokubeka iPCB ngqo, kwaye abantu abaninzi bayakholelwa. Le ngxelo kamva kamva yangqineka iyinto engento. Nokuba inkqubo yokuphuhlisa ngelo xesha yayibuyile, iliso lingenza njani ukuba liyixelele kumgama omncinci kuneenwele?
Emva koko, le ndlela yaqhubeka kwaye iguqulwe, kwaye ngokuthe ngcembe yavela enye indlela yomlinganiso. Kule mihla, abantu abaninzi bakholelwa ukuba kunokwenzeka ukuba balinganise inani lezixhobo ze-PCB ngenjongo yokulinganisa ezilunge ngakumbi
Nokuba lukhona nokuba lukhona na olo hlobo lwesixhobo esichanekileyo, kutheni singayiboni ukuba i-PCB ye-12-Well PCB ingamaxesha ama-3 ubukhulu bePCB ye-4-Weke? Iforum ye-EKA365 IForum ye-Electronics ikhumbuza wonke umntu onokuthi usebenzise iinkqubo ezahlukeneyo zokwenza imveliso. Akukho mgangatho ufanayo wemilinganiselo. Ungagweba njani inani leendawo ezisekwe kubunzima?
Ngapha koko, inani lemigca le-PCB linempembelelo enkulu kwiBhodi. Umzekelo, kutheni ufuna ubuncinci bee-6 ze-PCB ukufaka i-CPU ezimbini? Ngenxa yoku, i-PCB inokuba ne-3 okanye i-4 imiqondiso, ungqimba olu-1, kunye ne-1 okanye ezi-2 zamandla. Emva koko imigca yomqondiso inokwahlulwa kude ngokwaneleyo ukunciphisa ukuphazamiseka, kwaye kukho ukubonelelwa kwangoku.
Nangona kunjalo, uyilo lwe-PCB ye-2-Weker lwe-PCB lwanele kuquka iibhodi jikelele, ngelixa i-6-Wiker PCB ixabisa kakhulu kwaye ayinalo uphuculo lwendlela yokusebenza.
