I-Copper Coin PCB vs Metal Core PCB: Yikuphi Okungcono Ngokuphathwa Kwezishisayo?

Isingeniso

Amasistimu e-elekthronikhi anamandla amakhulu akhiqiza ukushisa okukhulu okwehlisa ukusebenza kahle futhi anciphise isikhathi sokuphila sengxenye. Ukuphatha okushisayo okusebenzayo sekube semqoka ezinhlelweni zokusebenza kusukela ekukhanyisweni kwe-LED kuya kuzilawuli zezimoto zikagesi. Ama-Metal core PCB abusa izixazululo ezishisayo iminyaka, ikakhulukazi kumamojula we-LED namamojula wokuphakelwa kwamandla.

Nokho, ukuqhathanisa kohlamvu lwekhopha lwe-PCB vs MCPCB kuveza umehluko omkhulu wokusebenza. Njengoba ukuminyana kwamandla kwanda, ingabe ubuchwepheshe be-PCB bemali yethusi obusafufusa budlula izixazululo ezivamile ze-MCPCB? Ukuqonda umehluko wesakhiwo nowokushisa phakathi kwalobu buchwepheshe kusiza onjiniyela bakhethe isixazululo esilungile sezinhlelo zokusebenza ezifunayo.

I-Copper Coin PCB vs MCPCB: Ukuqonda Izisekelo Zobuchwepheshe

Iyini i-Metal Core PCB (MCPCB)?

I -PCB eyinhloko yensimbi iqukethe ungqimba lwesisekelo sensimbi, ngokuvamile i-aluminium noma ithusi, oluboshwe ungqimba oluncane lwe-dielectric olune-foil yethusi phezulu. I-substrate yensimbi inikeza ukwesekwa kwesakhiwo futhi isebenza njengesisabalalisi sokushisa, iqhuba ukushisa ngokuvundlile.

Izinhlelo zokusebenza ezivamile zihlanganisa ama-LED amalambu, izibani zangaphambili zezimoto, namamojula okunikezwa kwamandla lapho ukukhishwa kokushisa okumaphakathi kwanele. Ubuchwepheshe be-MCPCB buhlinzeka ngokukhiqiza okuqondile ngokwethembeka okuqinisekisiwe ezinhlelweni ezishisayo ezimaphakathi nebanga.

Iyini i-Copper Coin PCB?

Ubuchwepheshe be-PCB bezinhlamvu zethusi bufaka amasilinda ethusi aqinile ngqo ngaphansi kwezingxenye ezikhiqiza ukushisa ngaphakathi kwe-PCB stackup. Lezi zinhlamvu zethusi zakha indlela yokushisa eqondile eqondile kusukela engxenyeni kuya engqimbeni yensimbi yangaphandle noma isinki yokushisa, idlula umgoqo we-dielectric wendabuko.

Le ndlela ifakazela ukuthi iwusizo ngokukhethekile kumamojula wamandla, izilawuli zezimoto zikagesi, nezinhlelo ze-silicon carbide noma ze-IGBT lapho imithombo yokushisa egxilile idinga ukuphathwa okushisayo okunolaka.

Ukusebenza Okushisayo: I-Copper Coin PCB vs Ukuqhathanisa kwe-MCPCB

Umehluko Obalulekile Wokuqhutshwa Kwe-Thermal

Umehluko oyisisekelo phakathi kohlamvu lwemali yethusi i-PCB vs MCPCB usezindleleni zazo zokuhambisa ezishisayo. I-MCPCB idizayina ukushisa komzila ngokusebenzisa isendlalelo se-dielectric kuya kusisekelo sensimbi, bese sikusakaza ngokuvundlile.
