Yintoni ibhodi enecala elinye elinamacala amabini anomaleko amaninzi?
Iibhodi ze-PCB zihlelwa ngokwenani leeleya zesekethe: i-single-side, i-double-side kunye ne-multi-layer board.Iibhodi eziqhelekileyo ze-multi-layer ngokubanzi ziyi-4-layer board okanye ii-6-layer boards, kunye neebhodi eziyinkimbinkimbi ze-multi-layer zinokufikelela ngaphezu kweshumi elinesibini.Inezi ntlobo zintathu zilandelayo zolwahlulo:
Iphaneli enye: Kweyona PCB isisiseko, amalungu agxininiswe kwelinye icala, kwaye iingcingo zigxininiswe kwelinye icala.Kuba iingcingo zivela kwicala elinye kuphela, olu hlobo lwePCB lubizwa ngokuba licala elinye (icala elinye).Ngenxa yokuba ibhodi enecala elilodwa inezithintelo ezininzi ezingqongqo kuyilo lwesekethe (kuba kukho icala elinye kuphela, i-wiring ayikwazi ukuwela kwaye kufuneka ibe yindlela eyahlukileyo), ngoko ke kuphela iisekethe zokuqala zisebenzisa olu hlobo lwebhodi.
Ibhodi enamacala amabini: Olu hlobo lwebhodi yesekethe lune-wiring kumacala omabini, kodwa ukusebenzisa iingcingo ezimbini, kufuneka kubekho uxhulumaniso olufanelekileyo lwesekethe phakathi kwamacala amabini."Iibhulorho" phakathi kweesekethe ezinjalo zibizwa ngokuba yi-vias.Ukudlula ngumngxuma omncinci ozaliswe okanye uqatywe ngentsimbi kwi-PCB, enokuthi idityaniswe kwiingcingo kumacala omabini.Ngenxa yokuba indawo yebhodi enamacala amabini inkulu ngokuphindwe kabini kunaleyo yebhodi enye, kwaye ngenxa yokuba i-wiring inokungenelela (inokuthi ifakwe kwelinye icala), ifaneleke ngakumbi ukusetyenziswa kwiisekethe. ezintsonkothileyo kunebhodi enecala elinye.
Ibhodi ye-Multilayer: Ukuze ukwandise indawo enokuthi ifakwe intambo, ibhodi ye-multilayer isebenzisa iibhodi zocingo ezizimeleyo okanye eziphindwe kabini.Sebenzisa i-double-sided njengomaleko wangaphakathi, ezimbini-zecala elilodwa njengomaleko wangaphandle okanye amabini aphindwe kabini njengomaleko wangaphakathi kunye namacala amabini angaphandle njengomaleko wangaphandle webhodi yesekethe eprintiweyo.Inkqubo yokubeka kunye nesixhobo sokugquma i-insulating bonding ngokushiyanayo kunye kunye nepateni yokuqhuba Iibhodi zeesekethe eziprintiweyo ezidityaniswe ngokweemfuno zoyilo zibe ngamaleko amane okanye amathandathu aprintiweyo iibhodi zeesekethe, ezaziwa ngokuba ziibhodi zesekethe eziprintiweyo ezininzi.Inani leengqimba zebhodi lithetha ukuba kukho iileya ezininzi ezizimeleyo zocingo.Ngokuqhelekileyo inani leeleya lilinganayo kwaye liqulethe iileya ezimbini ezingaphandle.Uninzi lweebhodi ze-motherboard zine-4 ukuya kwi-8 imigangatho yesakhiwo, kodwa ngokobuchwepheshe, iibhodi ze-PCB ezinomaleko ophantse ube yi-100 zinokufikelelwa kwithiyori.Uninzi lwee-supercomputers ezinkulu zisebenzisa ngokufanelekileyo ii-motherboards ezinomaleko amaninzi, kodwa ngenxa yokuba olu hlobo lwekhompyuter sele lunokutshintshwa liqela leekhompyuter ezininzi eziqhelekileyo, iibhodi ze-super-multilayer azisetyenziswa ngokuthe ngcembe.
Ngenxa yokuba iileya kwi-PCB zidityaniswe ngokuqinileyo, akukho lula ukubona elona nani, kodwa ukuba ujonga kufutshane kwi-motherboard, usenokuyibona.
Ngokohlelo oluthambileyo nolunzima: lwahlulwe kwiibhodi zeesekethe eziqhelekileyo kunye neebhodi zesekethe eziguquguqukayo.Izinto ekrwada PCB yi copper clad laminate, nto leyo substrate imathiriyeli ukwenza iibhodi zesekethe eprintiweyo.Isetyenziselwa ukuxhasa amacandelo ahlukeneyo, kwaye inokufezekisa ukudibanisa kombane okanye ukugquma kombane phakathi kwabo.Ngamafutshane, iPCB yibhodi ebhityileyo eneesekethe ezidityanisiweyo kunye namanye amacandelo e-elektroniki.Iza kuvela phantse kuso sonke isixhobo sombane.
