Kuyamba kwa MCPCB

MCPCB ndiye chidule cha Metal core PCBS, kuphatikiza PCB yochokera ku aluminiyamu, PCB yochokera mkuwa ndi PCB yachitsulo.

Aluminium based board ndiye mtundu wodziwika kwambiri.Zoyambira zimakhala ndi aluminiyamu pachimake, muyezo FR4 ndi mkuwa.Imakhala ndi nsalu yotchinga yotentha yomwe imataya kutentha m'njira yabwino kwambiri ndikuzizira zigawo.Pakadali pano, Aluminium Based PCB imatengedwa ngati yankho lamphamvu kwambiri.Aluminiyamu yochokera ku board imatha kulowa m'malo mwa bolodi yokhazikika ya ceramic, ndipo aluminiyumu imapereka mphamvu komanso kulimba kwa chinthu chomwe maziko a ceramic sangathe.

Chigawo chamkuwa ndi chimodzi mwa zigawo zachitsulo zokwera mtengo kwambiri, ndipo matenthedwe ake amatenthedwa bwino nthawi zambiri kuposa magawo a aluminiyamu ndi zitsulo zachitsulo.Ndiwoyenera kutulutsa kutentha kwambiri kwa ma frequency okwera kwambiri, zigawo zomwe zili m'zigawo zomwe zimakhala ndi kusiyana kwakukulu pakutentha kwambiri komanso kutsika komanso zida zolumikizirana zolondola.

Wosanjikiza wotenthetsera kutentha ndi chimodzi mwamagawo apakati a gawo lapansi lamkuwa, motero makulidwe a zojambula zamkuwa nthawi zambiri amakhala 35 m-280 m, zomwe zimatha kunyamula mphamvu zamagetsi.Poyerekeza ndi gawo lapansi la aluminiyamu, gawo lapansi lamkuwa limatha kukwaniritsa kutentha kwabwinoko, kuti zitsimikizire kukhazikika kwazinthuzo.

Kapangidwe ka Aluminium PCB

Circuit Copper Layer

Wozungulira mkuwa wosanjikiza amapangidwa ndikumangika kuti apange dera losindikizidwa, gawo lapansi la aluminiyamu limatha kunyamula mphamvu yapano kuposa FR-4 yokhuthala komanso m'lifupi mwake.

Insulating Layer

Wosanjikiza wotsekereza ndiye ukadaulo wapakatikati wa gawo lapansi la aluminiyamu, lomwe makamaka limagwira ntchito za kutchinjiriza ndi kuwongolera kutentha.Chigawo cha aluminium substrate insulating layer ndiye chotchinga chachikulu kwambiri chamafuta mugawo lamagetsi.Kutentha kwabwino kwa kutentha kwazitsulo zotetezera, kumapangitsanso kufalitsa kutentha komwe kumapangidwa panthawi yogwiritsira ntchito chipangizocho, komanso kuchepetsa kutentha kwa chipangizocho,Metal gawo lapansi.

Ndi zitsulo zotani zomwe tidzasankhe ngati gawo lapansi lotsekera zitsulo?

Tiyenera kuganizira kuchuluka kwa matenthedwe kowonjezera, mphamvu yamafuta, mphamvu, kuuma, kulemera, mawonekedwe apamwamba komanso mtengo wa gawo lapansi lachitsulo.

Nthawi zambiri, aluminiyamu ndi yotsika mtengo poyerekeza ndi mkuwa.Zomwe zilipo zotayidwa ndi 6061, 5052, 1060 ndi zina zotero.Ngati pali zofunika apamwamba madutsidwe matenthedwe, katundu makina, katundu magetsi ndi zinthu zina zapadera, mbale mkuwa, mbale zitsulo zosapanga dzimbiri, mbale chitsulo ndi silicon zitsulo mbale.

Kugwiritsa ntchito kwa MCPCB

1.Audio: Zolowetsa, zokulitsa zotulutsa, zokulitsa bwino, zokulitsa mawu, zokulitsa mphamvu.

2.Power Supply: Kusintha kwa regulator, DC / AC converter, SW regulator, etc.

3.Automobile: Electronic regulator, poyatsira, wowongolera magetsi, etc.

4.Computer: CPU board, floppy disk drive, zida zamagetsi, ndi zina.

5.Power Modules: Invert-er, solid-state relays, rectifier milatho.

6.Nyali ndi kuyatsa: nyali zopulumutsa mphamvu, mitundu yosiyanasiyana ya magetsi opulumutsa mphamvu a LED, kuyatsa panja, kuyatsa siteji, kuyatsa kwa kasupe
