Yintoni PCB yobhedu enzima?

Le PCB yakudala lukhetho lokuqala xa imisinga ephezulu ingenakuthintelwa: i -PCB yobhedu eshinyeneyo , eyenziwe ngetekhnoloji ye-etching yangempela. IiPCB zobhedu ezishinyeneyo ziphawulwa ngezakhiwo ezinobunzima bekopolo ukusuka kwi-105 ukuya kuma-400 µm. Ezi PCB zisetyenziselwa iziphumo zangoku ezinkulu (eziphezulu) kunye nokuphucula ulawulo lwe-thermal. Ubhedu olungqingqwa luvumela i-PCB-cross-amacandelo amakhulu kwimithwalo ephezulu yangoku kwaye ikhuthaza ukuchithwa kobushushu. Uyilo oluqhelekileyo luyi-multilayer okanye lunamacala amabini. 

Nangona kungekho nkcazo esemgangathweni ye-Heavy Copper, iyamkelwa ngokuqhelekileyo ukuba i-3 ounces (oz) yobhedu okanye ngaphezulu isetyenziswe kwimigangatho yangaphakathi nangaphandle yebhodi yesiphaluka eprintiweyo, ibizwa ngokuba yi- PCB yobhedu enzima . Nayiphi na isekethe enobunzima bobhedu obungaphezulu kwe-4 oz ngonyawo lwesikwere (ft2) ikwahlelwa njengePCB yobhedu enzima. Ubhedu olugqithisileyo luthetha i-20 oz ngeft2 ukuya kuma-200 oz ngeft2 nganye.

I-PCB yobhedu enzima ichongiwe njenge-PCB enobunzima be-copper eyi-3 oz nge-ft2 ukuya kwi-10 oz nge-ft2 kwimigangatho yangaphandle nangaphakathi. I-PCB yobhedu enzima iveliswa ngeentsimbi zobhedu ukusuka kwi-4 oz nge-ft2 ukuya kwi-20 oz nge-ft2. Ubunzima bobhedu obuphuculweyo, kunye ne-plating ebanzi kunye ne-substrate efanelekileyo kwimingxuma ephumayo inokutshintsha ibhodi ebuthakathaka ibe yiplatifomu ye-wiring ehlala ixesha elide kunye nokuxhomekeka. Iikondaktari zobhedu ezinzima zinokunyusa ubukhulu bePCB ngokupheleleyo. Ubunzima bobhedu kufuneka buhlale buqwalaselwa ngexesha lesigaba soyilo lwesekethe. Umthamo okhoyo ngoku unqunywe ukusuka kububanzi kunye nobukhulu bobhedu obunzima.

Inzuzo ephambili yeebhodi zesekethe zobhedu obunzima kukukwazi kwabo ukusinda ekutyhilekeni rhoqo ngokugqithisileyo, amaqondo obushushu aphakamileyo kunye nebhayisekile ephindaphindayo ye-thermal, enokutshabalalisa ibhodi yesekethe eqhelekileyo ngemizuzwana. Ibhodi yobhedu enzima inomlinganiselo ophezulu wokunyamezela, okwenza ukuba ihambelane nezicelo kwiimeko ezinzima ezifana, ukhuseleko kunye neemveliso zoshishino lwe-aerospace.

Ezinye zezibonelelo ezongezelelweyo zeebhodi zesekethe zobhedu ezinzima zezi:

Ubungakanani bemveliso yeCompact ngenxa yobunzima obuninzi bobhedu kumaleko omnye wokujikeleza

Iindlela zobhedu ezinobunzima zigqithisa umsinga ophakamileyo ngePCB kwaye zincede ekudluliseleni ubushushu kwindawo yokuntywila yobushushu yangaphandle.

Umahluko phakathi kwe-PCB eqhelekileyo kunye ne-Thick Copper PCB

Ii-PCB ezisemgangathweni zinokuveliswa ngeenkqubo zokuhombisa ubhedu kunye ne-plating. Ezi PCB zityatyekwe ukongeza ubukhulu bobhedu kwiinqwelomoya, umkhondo, ii-PTHs, kunye neepads. Isixa sobhedu esisetyenzisiweyo kwimveliso yeePCB eziqhelekileyo yi-1oz. Kwimveliso ye-PCB yobhedu enzima, inani lobhedu olusetyenzisiweyo likhulu kune-3oz.

Kwiibhodi zesekethe ezisemgangathweni, i-copper etching kunye ne-plating techniques isetyenziswa. Nangona kunjalo, ii-PCB zobhedu ezinzima ziveliswa ngokucocwa ngokwahlukileyo kunye nokubekwa kwamanyathelo. Ii-PCB eziqhelekileyo zenza imisebenzi elula ngelixa iibhodi zobhedu ezinzima zenza imisebenzi enzima.

Ii-PCBs eziqhelekileyo ziqhuba umsinga ophantsi ngelixa ii-PCB zobhedu ezinzima ziqhuba ngoku phezulu. IiPCB zobhedu ezishinyeneyo zilungele usetyenziso olukwisiphelo esiphezulu ngenxa yokuhanjiswa kwazo okusebenzayo kobushushu. IiPCB zobhedu ezinzima zinamandla omatshini angcono kuneePCB eziqhelekileyo. Iibhodi zesekethe zobhedu ezinzima zonyusa amandla ebhodi apho zisetyenziswa khona.

Ezinye izinto ezenza iiPCB zobhedu ezishinyeneyo zahluke kwezinye iiPCB

Ubunzima bobhedu: Le yeyona nto iphambili yokwahlula iiPCB zobhedu olunzima. Ubunzima bobhedu bubhekisa kubunzima bobhedu obusetyenziswa kwindawo yesikwere. Lo bunzima budla ngokulinganiswa ngee-ounces. Ibonisa ukutyeba kobhedu kumaleko.

Iileya zangaphandle: Ezi zibhekisa kumaleko obhedu angaphandle ebhodi. Amacandelo e-elektroniki adla ngokudityaniswa kumaleko angaphandle. Iileya zangaphandle ziqala ngefoyile yobhedu eqatywe ngobhedu. Oku kunceda ukwandisa ubukhulu. Ubunzima bobhedu bemigangatho yangaphandle bucwangciswe kwangaphambili kuyilo oluqhelekileyo. Umenzi wePCB yobhedu olunzima unokuguqula ubunzima kunye nobukhulu bobhedu ukuze buhambelane nemfuno yakho.

Iileya zangaphakathi: Ubukhulu be-dielectric, kunye nobunzima bobhedu bemigangatho yangaphakathi, buchazwe kwangaphambili kwiiprojekthi eziqhelekileyo. Nangona kunjalo, ubunzima bobhedu kunye nobukhulu kula maleko bunokutshintshwa ngokusekelwe kwiimfuno zakho.

IiPCB zobhedu ezinzima zisetyenziselwa iinjongo ezininzi ezifana neziguquli ezicwangcisiweyo, ukuchithwa kobushushu, ukuhanjiswa kwamandla aphezulu, abaguquli bamandla, njl. Kukho imfuno eyongeziweyo yeebhodi ezinobhedu ezinobunzima kwikhompyuter, iimoto, umkhosi kunye nolawulo lwemizi-mveliso.

Iibhodi zesekethe eziprintiweyo ezinobhedu ezinzima nazo zisetyenziswa apha:

Izibonelelo zamandla, abaguquli bamandla

Ukuhanjiswa kwamandla
