Mkuwa m'munsi Chitsulo pachimake pcb kwa dongosolo panja kusonyeza
Ichi ndi 2 layermaziko amkuwaPCB kwakuyatsamakampani.A Metal Core Printed Circuit Board (MCPCB), kapena PCB yotentha, ndi mtundu wa PCB womwe uli ndi chitsulo monga maziko ake a gawo lofalitsa kutentha kwa bolodi.

Metal Core PCB kapena MCPCB
Metal Core PCB (MCPCB) imadziwika kuti Metal Backplane PCB kapena Thermal PCB.Mtundu uwu wa PCB umagwiritsa ntchito zitsulo m'malo mwa FR4 wamba pa maziko ake, gawo la bolodi lakuya.
As amadziwikakutentha kumapangidwa pa bolodi pazifukwa zina Zamagetsi zamagetsi panthawi yogwira ntchito.Chitsulo chimasamutsa kutentha kuchokera pa bolodi lozungulira ndikuchilozera ku Chitsulo chachitsulo kapena chitsulo chothandizira kutentha kwachitsulo ndi chinthu chofunikira chosungira.
Mu multilayer PCB mudzapeza chiwerengero chofanana cha zigawo zomwe zimagawidwa kumbali yachitsulo.Mwachitsanzo, ngati muyang'ana Pa 12-wosanjikiza PCB, mupeza zigawo zisanu ndi chimodzi pamwamba ndi zisanu ndi chimodzi pansi, pakati ndi chitsulo pakati.
MCPCB kapena Metal Core PCB Imadziwikanso kuti ICPB kapena Insulated Metal PCB, IMS kapena Insulated Metal Substrates, Metal Clad PCBs ndi Thermal Clad PCBs.
Fkapena inu Kuti mumvetse bwino tidzangogwiritsa ntchito mawu akuti chitsulo pakati PCB m'nkhaniyi.
Kapangidwe koyambira kachitsulo kachitsulo PCB kumaphatikizapo izi:
Gulu la Copper - 1oz.to 6oz.(zofala kwambiri ndi 1oz kapena 2oz)
dera wosanjikiza
Dielectric wosanjikiza
Chigoba cha solder
Sink yamoto kapena sink ya kutentha (chitsulo chapakati)
Ubwino wa MCPCB
Thermal Conductivity
CEM3 kapena FR4 sizabwino pakutentha.ngati kutentha
The gawo lapansi ntchito PCBs ndi madutsidwe osauka ndipo akhoza kuwononga zigawo zikuluzikulu za bolodi PCB.Ndipamene ma PCB achitsulo amabwera bwino.
MCPCB ili ndi matenthedwe abwino kwambiri oteteza zinthu kuti zisawonongeke.
Hkudya kudya
Amapereka mphamvu yabwino kwambiri yozizirira.Ma Metal core PCB amatha kutaya kutentha kuchokera ku IC bwino kwambiri.Thermally conductive wosanjikiza amasamutsa kutentha kwa zitsulo gawo lapansi.
Kukhazikika kwa sikelo
Iwo amapereka apamwamba dimensional bata kuposa mitundu ina ya PCBs.Kutentha kumasinthidwa kuchoka pa 30 digiri Celsius mpaka 140-150 madigiri Celsius, kusintha kwapakati pazitsulo zotayidwa ndi 2.5 ~ 3%.
Rkuchepetsa kusokonezeka
Popeza ma PCB achitsulo ali ndi kutentha kwabwino komanso kutulutsa kwamafuta, samakonda kupotokola chifukwa cha kutentha komwe kumapangitsa.Chifukwa cha chikhalidwe ichi chachitsulo pachimake, PCBs ndi kusankha koyamba kwa ntchito magetsi amene amafuna kusintha kwakukulu.
