Anokwikwidza PCB Mugadziri

MCPCB ndiyo chidimbu cheMetal core PCBs, kusanganisira aluminium based PCB, copper based PCB uye iron based PCB.

Aluminium based board ndiyo yakajairika mhando.Iyo yekutanga zvinhu ine aluminium musimboti, yakajairwa FR4 uye mhangura.Iyo ine thermal clad layer inobvisa kupisa nenzira inoshanda zvakanyanya panguva yekutonhodza zvikamu.Parizvino, Aluminium Yakavakirwa PCB inoonekwa semhinduro kune yakakwirira simba.Aluminium based board inogona kutsiva frangible ceramic based board, uye aruminiyamu inopa simba uye kusimba kune chigadzirwa icho mabhesi eceramic haagone.

Copper substrate ndeimwe yeanonyanya kudhura simbi substrates, uye yayo yekupisa conductivity yakawanda kakawanda kupfuura iyo yealuminium substrates uye iron substrates.Iyo inokodzera zvakanyanya zvinobudirira kupisa kupisa kwepamusoro frequency maseketi, zvikamu mumatunhu ane mutsauko mukuru mukupisa uye kwakaderera tembiricha uye chaiyo yekutaurirana michina.

Thermal insulation layer ndiyo imwe yepakati zvikamu zvemhangura substrate, saka ukobvu hwemhangura foil kazhinji 35 m-280 m, iyo inogona kuwana yakasimba ikozvino-yekutakura kugona.Kuenzaniswa nealuminium substrate, mhangura substrate inogona kuwana zvirinani kupisa kupisa mhedzisiro, kuitira kuve nechokwadi kugadzikana kwechigadzirwa.

Chimiro cheAluminium PCB

Circuit Copper Layer

Iyo yedunhu copper layer inogadzirwa uye yakamisikidzwa kuti iite yakadhindwa dunhu, iyo aluminium substrate inogona kutakura yakakwira ikozvino kupfuura yakafanana gobvu FR-4 uye yakafanana trace hupamhi.

Insulating Layer

Iyo insulating layer ndiyo yakakosha tekinoroji yealuminium substrate, iyo inonyanya kutamba mabasa ekudzivirira uye kupisa conduction.Iyo aluminium substrate insulating layer ndiyo hombe yekupisa inodzivirira mune yemagetsi module chimiro.Iyo iri nani iyo yekupisa conductivity ye insulating layer, iyo inonyatso shanda kuparadzira kupisa kunogadzirwa panguva yekushanda kwechigadzirwa, uye kudzikisa tembiricha yechigadzirwa,

Metal substrate

Imhandoi yesimbi yatichasarudza seyo insulating metal substrate?

Isu tinofanirwa kufunga nezve thermal yekuwedzera coefficient, thermal conductivity, simba, kuoma, uremu, nzvimbo yepamusoro uye mutengo wesimbi substrate.

Kazhinji, aluminium yakachipa zvakachipa pane mhangura.Inowanikwa aruminiyamu zvinhu 6061, 5052, 1060 zvichingodaro.Kana paine zvakakwirira zvinodikanwa zvekupisa conductivity, midziyo yemagetsi, zvivakwa zvemagetsi uye zvimwe zvinhu zvakakosha, mahwendefa emhangura, mahwendefa esimbi, mahwendefa esimbi uye silicon simbi mahwendefa anogonawo kushandiswa.

Application yeMCPCB

1. Audio : Input, inobuda amplifier, balanced amplifier, audio amplifier, simba rekusimudzira.

2. Power Supply: Kushandura regulator, DC / AC converter, SW regulator, nezvimwewo.

3. Motokari: Electronic regulator, ignition, magetsi ekugadzirisa magetsi, nezvimwewo.

4. Kombuta: CPU board, floppy disk drive, magetsi emagetsi, nezvimwe.

5. Power Modules: Inverter, solid-state relays, rectifier mabhiriji.

6. Mwenje uye mwenje: marambi ekuchengetedza simba, akasiyana-siyana ane mavara-anochengetedza magetsi e LED, mwenje wekunze, mwenje wedariro, tsime mwenje.
