Metal Core PCB kana MCPCB
Metal Core PCB (MCPCB) inozivikanwa seMetal Backplane PCB kana Thermal PCB.Iyi mhando yePCB inoshandisa simbi zvinhu pachinzvimbo cheyakajairwa FR4 kune hwaro hwayo, iyo inopisa sink chikamu chebhodhi.
As inozivikanwakupisa kunogadzirwa pabhodhi nokuda kwechimwe chikonzero Electronic components panguva yekushanda.Simbi inotamisa kupisa kubva kubhodhi redunhu uye inoidzosera kuMetal core kana simbi inopisa sink inotsigira uye kiyi yekuchengetedza Element.
Mune multilayer PCB iwe unowana yunifomu nhamba yezvikamu zvakagoverwa padivi resimbi musimboti.Semuenzaniso, kana iwe ukatarisa Pa 12-layer PCB, unowana matanhatu akaturikidzana kumusoro uye matanhatu akaturikidzana pazasi, pakati pane simbi core.
MCPCB kana Metal Core PCB Iyo inozivikanwawo seICPB kana Insulated Metal PCB, IMS kana Insulated Metal Substrates, Metal Clad PCBs uye Thermal Clad PCBs.
Fkana iwe Kuti unzwisise zviri nani isu tichangoshandisa izwi rekuti simbi musimboti PCB muchinyorwa ichi.
Iyo yakakosha chimiro chesimbi musimboti PCB inosanganisira zvinotevera:
Mhangura Layer - 1oz.to 6oz.(inonyanya kuzivikanwa ndeye 1oz kana 2oz)
circuit layer
Dielectric layer
Solder mask
Kupisa kunyura kana kupisa sink (metal core layer)
Kubatsira kweMCPCB
Thermal Conductivity
CEM3 kana FR4 haina kunaka pakuitisa kupisa.kana kuchipisa
Iwo ma substrates anoshandiswa muPCB ane urombo conductivity uye anogona kukuvadza zvikamu zvePCB board.Ndipo apo simbi yepakati PCBs inouya inobatsira.
MCPCB ine yakanakisa yekupisa conductivity kuchengetedza zvikamu kubva mukukuvara.
Hkudya kuparara
Inopa yakanakisa kutonhora kugona.Metal core PCBs inogona kubvisa kupisa kubva kuIC zvakanyanya.Iyo thermally conductive layer inobva yaendesa kupisa kune substrate yesimbi.
Scale kugadzikana
Inopa yakakwira dimensional kugadzikana pane mamwe marudzi ePCB.Mushure mekunge tembiricha yashandurwa kubva pa30 madhigirii celsius kuenda pa140-150 madhigirii celsius, dimensional shanduko yesimbi yealuminium core i2.5 ~ 3%.
Reduce distortion
Sezvo simbi yepakati PCBs ine yakanaka yekupisa kupisa uye kupisa conductivity, ivo havanyanyi kuita deformation nekuda kwekupikiswa kupisa.Nekuda kwehunhu uhu hwesimbi musimboti, maPCB ndiyo yekutanga sarudzo yemagetsi maapplication ayo anoda yakakwirira switch.
