I-Metal Core PCB noma i-MCPCB
I-Metal Core PCB (MCPCB) yaziwa ngokuthi i-Metal Backplane PCB noma i-Thermal PCB.Lolu hlobo lwe-PCB lusebenzisa into yensimbi esikhundleni se-FR4 ejwayelekile yesisekelo sayo, ingxenye yesinki yokushisa yebhodi.
As kuyaziwaukushisa kukhiqizwa ebhodini ngesizathu esithile Izingxenye ze-Electronic ngesikhathi sokusebenza.I-Metal idlulisa ukushisa ukusuka ebhodini lesekethe futhi ikuqondise kabusha ku-Metal core noma usinki wokushisa wensimbi kanye nesici sokhiye sokulondoloza.
Ku-PCB enezingqimba eziningi uzothola inombolo efanayo yezendlalelo ezisatshalaliswe ohlangothini oluwumgogodla wensimbi.Isibonelo, uma ubheka Ku-PCB enezingqimba eziyi-12, uzothola izendlalelo eziyisithupha phezulu neziyisithupha ngezansi, phakathi nendawo kukhona insimbi.
I-MCPCB noma i-Metal Core PCB Eyaziwa nangokuthi i-ICPB noma i-Insulated Metal PCB, i-IMS noma i-Insulated Metal Substrates, i-Metal Clad PCBs kanye ne-Thermal Clad PCBs.
Fnoma wena Ukuze uqonde kangcono sizosebenzisa igama elithi metal core PCB kuso sonke lesi sihloko.
Isakhiwo esiyisisekelo se-PCB ewumgogodla wensimbi sihlanganisa okulandelayo:
Isendlalelo sethusi - 1oz.to 6oz.(okuvamile yi-1oz noma i-2oz)
ungqimba wesifunda
Isendlalelo se-Dielectric
Imaski ye-solder
Usinki wokushisa noma usinki wokushisa (ungqimba oluyisisekelo lwensimbi)
Inzuzo ye-MCPCB
I-Thermal Conductivity
I-CEM3 noma i-FR4 ayilungile ekuphatheni ukushisa.uma kushisa
Ama-substrates asetshenziswa kuma-PCB anokungahambi kahle kahle futhi angalimaza izingxenye zebhodi le-PCB.Kulapho ama-PCB angumgogodla wensimbi eza khona ewusizo.
I-MCPCB ine-thermal conductivity enhle kakhulu yokuvikela izingxenye emonakalweni.
Hdla ukuchithwa
Inikeza umthamo omuhle kakhulu wokupholisa.I-Metal core PCB ingasabisa ukushisa okuvela ku-IC kahle kakhulu.Isendlalelo se-thermal conductive bese sidlulisela ukushisa ku-substrate yensimbi.
Ukuzinza kwesikali
Inikeza ukuzinza okuphezulu kobukhulu kunezinye izinhlobo zama-PCB.Ngemuva kokuthi izinga lokushisa lishintshiwe lisuka ku-30 degrees Celsius liye ku-140-150 degrees Celsius, ushintsho lwe-dimensional lwensimbi ye-aluminium luyi-2.5 ~ 3%.
Rehlisa ukuhlanekezela
Njengoba i-metal core PCB inokukhipha ukushisa okuhle kanye ne-thermal conductivity, awathambekele kangako ekuguquguqukeni ngenxa yokushisa okubangelwe.Ngenxa yalesi sici somongo wensimbi, ama-PCB ayinketho yokuqala yezinhlelo zokusebenza zokunikezwa kwamandla ezidinga ukushintshwa okuphezulu.
