Gwaro rekutanga kuMetal Core PCBs

Mabhodhi esimbi anodhindwa esimbi (MCPCBs) akakosha mumagetsi emazuva ano pakugadzirisa kupisa kunogadzirwa nezvinhu zvine simba guru. Nekubatanidza substrate yesimbi—kazhinji aruminiyamu, mhangura, kana copper alloy—mabhodhi aya anopa conductivity yekupisa yepamusoro kana tichienzanisa nemaPCB akajairwa eFR4.

Kune vanotanga, kunzwisisa mashandiro anoita MCPCBs anotanga nekuziva zvinhu zvavo zvakakosha, marudzi ekuvaka, uye mabhenefiti ekuita. Ichi chinyorwa chinopa mucherechedzo wakajeka weanowanzo shandiswa macores, makuru ezvimiro mhando, yakakosha mabhenefiti, uye anoshanda mashandisirwo eMetal Core PCBs mumaindasitiri akadai semwenje we LED, magetsi emotokari, uye masisitimu emagetsi.

Chii chinonzi Metal Core PCB?

Metal Core PCBs (MCPCBs) inomiririra chikamu chehunyanzvi cheakadhindwa edunhu mabhodhi anobatanidza simbi substrates-kunyanya aruminiyamu kana mhangura-sehwaro hwezvinhu panzvimbo yechinyakare FR4 fiberglass. Uyu mutsauko wakakosha wedhizaini unogonesa kudziya kwemazinga e1-4 W/mK, zvinoshamisa kudarika maPCB akajairwa pa0.3 W/mK.

Iyo dhizaini ine zvikamu zvitatu zvakakosha zvinoshanda mukuwirirana:

• Metal Base Layer -Inopa tsigiro yezvimiro uye yekutanga kupisa kupisa nzira
• Thermally Conductive Dielectric -Magetsi anozvitsaura paunenge uchichengetedza kupisa kwekufambisa
• Copper Circuit Layer - Inotakura masaini emagetsi ane chiyero chakakora kubva pa1-4 oz

Ichi chivakwa chinogadzira inoshanda yekupisa manejimendi system uko kupisa kunoyerera zvakananga kubva kune zvikamu kuburikidza nedielectric kupinda musimbi substrate, yobva yaparara pabhodhi rese. Kune maapplication anopfuura 1W pachikamu, tekinoroji iyi inova yakakosha kuchengetedza tembiricha yekushanda yakachengeteka uye kuve nechokwadi chekuvimbika kwenguva refu.

Anowanzo Kushandiswa Cores muMetal Core PCBs

Aluminium Core Substrates

Aluminium inotonga simbi yepakati PCB musika, inoverengera anopfuura makumi manomwe neshanu muzana ezvekushandisa nekuda kweiyo yakakwana chiyero chekuita uye hupfumi. Standard aluminium substrates inopa:
