Ubhedu olunzima PCB produce 4 or more ounces of copper on each layer. Four ounce copper PCBS are most commonly used in commercial products. Iingxube zeCopper zingaba phezulu kuma-ounces angama-200 ngeenyawo zenyawo. Ubunzima bePCBS busetyenziswa ngokubanzi kwi-elektroniki kunye neesekethe ezifuna ukuhanjiswa kwamandla okuphezulu. In addition, the thermal strength these PCBS provide is impeccable. Kwizicelo ezininzi, ngakumbi i-elektroniki, uluhlu lwe-thermal lubalulekile kuba amaqondo obushushu aphezulu enza umonakalo kwizinto ezinobuthathaka ze-elektroniki kwaye achaphazela kakubi ukusebenza kwesekethe.

Ubushushu ukusasaza amandla & GT; Ii-PCBS zethusi ezinobunzima ziphezulu kakhulu kuneePCBS ezingaqhelekanga. Heat dissipation is critical to developing robust circuits. Ukulungiswa kwesiginali esingalunganga akusayi kuchaphazela ukusebenza kwezixhobo ze-elektroniki, kodwa kuya kunciphisa ubomi benkonzo yesekethe.

Ukufakelwa kweentambo zombane okuphezulu kunokuphuhliswa kusetyenziswa ii-PCBS zobhedu obunzima. Lo matshini wiring ubonelela ngokuthembekileyo ngakumbi ekuphatheni uxinzelelo olushushu kwaye ubonelela ngokugqibezela ngelixa udibanisa amajelo amaninzi kwipleyiti enye.

Ubunzima bePCBS busetyenziswa ngokubanzi kwiimveliso ezahlukeneyo kuba zibonelela ngemisebenzi eyahlukeneyo ukuphucula ukusebenza kwesekethe. These PCBS are widely used in high-power equipment such as transformers, radiators, inverters, military equipment, solar panels, automotive products, welding equipment and power distribution systems.

Imveliso ye-PCB enobunzima

Njengakwi-PCBS esemgangathweni, ii-PCBS zobhedu ezinobunzima zifuna ukucokiswa ngakumbi.

I-PCBS yesiko enzima yemveli yenziwa kusetyenziswa itekhnoloji ephelelwe lixesha, ekhokelela ekulandeleleni okungalinganiyo nasekucofeni i-PCB, kukhokelela ekusileleni. Today, however, modern manufacturing techniques support fine cuts and minimal bottom cuts.

Unyango olushushu kunyango lwe-PCB enzima

Izinto ezinje ngoxinzelelo lwe-thermal zibalulekile kuyilo lweesekethe kwaye iinjineli kufuneka zisuse kangangoko kunokwenzeka.

Ixesha elingaphezulu, ubuchwephesha bokwenza i-PCB buye bavela, kunye neetekhnoloji ezahlukeneyo zePCB zenziwe, ezinje ngealuminium PCBS, ekwaziyo ukuphatha uxinzelelo lobushushu.

Kukudla kwabayili be-PCB abanzima ukuba basebenze ngokufudumeleyo kunye noyilo lokusingqongileyo ngelixa benciphisa uhlahlo-lwabiwo mali ngelixa kugcinwa iisekethe.

Ngenxa yokuba ubushushu bezinto zombane buya kukhokelela ekusileleni, nokuba busemngciphekweni wobomi, ulawulo lweengozi alunakuhoywa.

The traditional process for achieving heat dissipation quality is to use an external heat sink, connected to the heating component. Kuba, ngaphandle kokuchithwa kobushushu, indawo yokufudumeza isondela kubushushu obuphezulu, ukubususa obu bushushu, irediyetha isebenzisa ubushushu ukusuka kwinxalenye kwaye ibudlulisele kwimeko engqongileyo. Usually, these radiators are made of copper or aluminum.The use of these radiators not only exceeded the development cost, but also required more space and time. The result, though, doesn’t even come close to the cooling power of a heavy copper PCB.

Kwi-PCBS enzima yobhedu, isinki yokufudumeza ifakwe ebhodini ngexesha lokuvelisa, endaweni yokusebenzisa nasiphi na isinki sangaphandle sobushushu. As the external radiator requires more space, there are fewer restrictions on the placement of the radiator.

Ngenxa yokuba isinki yokufudumeza ifakwe kwibhodi yesekethe kwaye iqhagamshele kumthombo wobushushu usebenzisa i-conductive through-hole kunokuba usebenzise nakuphi na ujongano kunye namalungu oomatshini, ubushushu buhanjiswa ngokukhawuleza, okukhokelela ekuphuculeni ixesha lokusasaza ubushushu.

Imingxunya eshushu yokungena kwi-PCBS yobhedu enzima ivumela ukusasazeka kobushushu ngakumbi kunezinye iitekhnoloji, kuba i-thermal through-hole iphuhliswa ngobhedu. Ukongeza, uxinano lwangoku luphuculwe kwaye umphumo wesikhumba uncitshisiwe.

Advantages of heavy copper PCB: <

Izinto eziluncedo ze-PCB enzima yobhedu yenza ukuba kubaluleke kakhulu kuphuhliso lwesekethe yamandla aphezulu. Heavy copper concentration can handle high power and high heat, which is why high power circuits have been developed using this technology. Iisekethe ezinjalo azinakuphuhliswa nge-PCBS egxile kubhedu kuba ayinakumelana noxinzelelo olukhulu lwe-thermal olubangelwa kukuphakama okuphezulu kunye nokuhamba ngoku. I-PCBS ye-copper enobunzima ihlala ithathwa njengee-PCBS eziphezulu ngoku ngenxa yesikhundla sayo sokupholisa.

Ubudlelwane phakathi kobunzima bobhedu kunye nekhoyo ngoku yinto ebalulekileyo ekusebenziseni i-PCB enzima yobhedu. Njengoko uxinzelelo lobhedu lonyuka, kukwanjalo nayo yonke indawo enqamlezileyo yecandelo lobhedu, elinciphisa ukumelana kwisekethe. Njengoko sisazi, ilahleko ziyonakalisa kuyo nayiphi na uyilo, kwaye uxinzelelo lobhedu lwenza ezi PCBS zinciphise uhlahlo-lwabiwo mali.

Ukuqhutywa kwangoku yinto ebalulekileyo, ngakumbi xa ujongana neempawu zamandla asezantsi, kunye nokuqhutywa ngoku kwePCBS enzima yobhedu kuyaphuculwa kukunganyangeki okuncinci.

Izihlanganisi zibalulekile kunxibelelwano lwejumper. However, connectors are often difficult to maintain on traditional PCBS. Ngenxa yamandla asezantsi ee-PCBS ngamanye amaxesha, indawo yokudibanisa ihlala ichaphazeleka ngoxinzelelo loomatshini, kodwa i-PCBS enzima yobhedu ibonelela ngamandla aphezulu kunye nokuqinisekisa ukuthembeka okuphezulu.

Ukuvelisa iRBMING ye-PCB enzima

Ukuveliswa kwe-PCB enzima kufuna ukhathalelo olufanelekileyo, kunye nokuphathwa gwenxa ngexesha lokuvelisa kunokukhokelela ekusebenzeni okungalunganga, uhlala ucinga ngeenkonzo zomenzi onamava.

RAYMING ibonelela ngezixhobo zolawulo lwePCB kuzo zonke iintlobo zePCBS. I-RAYMING ibigxile kakhulu kwimveliso ye-PCB enzima kunye nokuphuhlisa imifanekiso ekumgangatho ophezulu kwiminyaka elishumi edlulileyo.

I-PCBS enzima yobhedu yenziwa koomatshini abazihambelayo, abasenza sikwazi ukuphuhlisa ii-PCBS ezinokuthenjwa. Ukuza kuthi ga ngoku, siphuhlise ii-PCBS ezingqimba ezimbini ukuya kuthi ga kwi-20 i-oun, ii-PCBS ezininzi ezilinganisa ii-ounces ezi-4-6 zobhedu.
