I-PCB yeCopper etyebileyo
Iimpawu zobuGcisa eziphambili
- Umthamo Wokuthwala Ngoku: Ubhedu olujiyileyo lunciphisa ukumelana nokulandelelana, nto leyo evumela ukuhamba kombane okuphezulu (umz., 100A+ ukuya kwi-1mm ububanzi, 10 oz ubhedu olulandelelana).
- Ulawulo lobushushu: Ukuphuculwa kokusasazwa kobushushu ngokusebenzisa umbane ophezulu wekopolo (401 W/m·K), okulungeleyo izixhobo ezixineneyo ngamandla.
- Ukuqina koomatshini: Ukomelela kolwakhiwo oluphuculweyo kwiindawo ezirhabaxa (umz., ukungcangcazela kweemoto, ukuthuthumela kwemizi-mveliso).
Ukusebenza koMbane okungalinganiyo
Ukumelana okuphantsi: Inciphisa ukulahleka kwamandla kwiindlela zamandla aphezulu (umz., i-10 oz copper ine-1/3 yokumelana ne-3 oz copper).
Ukunyaniseka kweSignali eZinzileyo: Ukwehla okuncinci kwamandla ombane kwiinethiwekhi zokusasazwa kwamandla, kubalulekile kwiinkqubo zeemoto nezoshishino.
Ukuphathwa Okuphezulu Kobushushu
Ukusasazwa kobushushu okusebenzayo: Iileya zekopolo zisebenza njengezithinteli zobushushu, zithintela ubushushu obugqithisileyo bezinto ezisetyenziswa kumbane nakwiimoto.
Ukumelana noMjikelo woBushushu: Iyamelana nokuguquguquka okuphindaphindiweyo kobushushu (-40°C ukuya ku-+125°C) ngaphandle kokususwa kwe-distribution.
Ukuqina Koomatshini
Ulwakhiwo Olunzima: Iindawo zokugquma eziqinisiweyo kunye neendawo zokuqhagamshela zinciphisa ukungasebenzi kakuhle koxinzelelo loomatshini.
Uyilo Oluqinileyo: Ifanelekile kwiindawo ezinobungozi (umz., emkhosini, kwinqwelo-moya, nakwimishini enzima).
Ukuguquguquka koyilo
IiStaki zeMaleko eziDibeneyo: Hlanganisa iileya zamandla obhedu obukhulu (umz., 10 oz) kunye neeleya zesignali ezincinci (umz., 1 oz) ukuze usebenze kakuhle.
Inkxaso yezinto ezininzi: Ifumaneka kwi-FR-4, i-aluminium, i-ceramic (Al₂O₃/AlN), kunye ne-substrates eziguquguqukayo.

Ukufakelwa ngombane
Kwimaleko ukuya kuthi ga kwi-10 oz, kusetyenziswa i-cladding ye-copper etyebileyo. -
I-Lamination
Ifoyile ebomvu yobhedu ebotshelelweyo (10–14 oz) kunye ne-prepreg ukuze kubekho iileya ezityebileyo kakhulu. -
Imaski yeSolder
Ukutshiza nge-electrostatic kuqinisekisa ukugqunywa okufanayo kwiindawo ezilinganayo zobhedu.
