Kufotokozera Kwachidule:

Mosiyana ndi Single wosanjikiza MCPCB, pawiri mbali MCPCB amafunanso zina kukanikiza sitepe kuti laminate fano matenthedwe conductive laminate ndi zitsulo pachimake (wotchedwanso zitsulo m'munsi) pamodzi. Koma nthawi zina, ena yaiwisi zitsulo Clad ogulitsa zinthu kupereka bolodi zinthu zimene laminated kale.

Kodi Multi Layers MCPCB ndi chiyani?

Bokosi Metal Core Printed Circuit Board (MCPCB) , yomwe imadziwikanso kuti PCB yothandizidwa ndi zitsulo, ndi mtundu wa PCB womwe uli ndi zitsulo zachitsulo monga maziko ake a gawo lofalitsa kutentha kwa bolodi. Chitsulo chokhuthala (nthawi zonse aluminium kapena mkuwa) chimakwirira mbali imodzi ya PCB. Chitsulo chachitsulo chikhoza kutanthauza chitsulo, kukhala pakati penapake kapena kumbuyo kwa bolodi. Cholinga cha pachimake cha MCPCB ndikuwongolera kutentha kutali ndi zigawo zofunika kwambiri za board ndikupita kumadera osafunikira kwambiri monga zitsulo za heatsink kapena zitsulo. Zitsulo zoyambira mu MCPCB zimagwiritsidwa ntchito ngati m'malo mwa FR4 kapena CEM3 board.

Bolodi yosindikiza yachitsulo (MCPCB) yomwe imadziwikanso kuti thermal PCB, imakhala ndi chitsulo ngati maziko ake kusiyana ndi FR4 yachikhalidwe, pagawo la bolodi. Kutentha kumawonjezeka chifukwa cha zigawo zina zamagetsi panthawi ya bolodi. Cholinga cha chitsulo ndikupatutsa kutentha kumeneku kuchoka kuzinthu zofunikira kwambiri ndikupita kumadera osafunika kwambiri monga zitsulo zazitsulo za heatsink kapena zitsulo. Chifukwa chake, ma PCB awa ndi oyenera kuwongolera kutentha.

Mu multilayer MCPCB, zigawozi zidzagawidwa mofanana kumbali zonse zachitsulo chachitsulo. Mwachitsanzo, pa bolodi la magawo 12, pakati pazitsulo pamakhala zigawo 6 pamwamba ndi 6 pansi.

Ma MCPCBs amatchedwanso insulated metallic substrate (IMS), insulated metal PCBs (IMPCB), ma PCB ovala otentha, ndi ma PCB ovala zitsulo. M'nkhaniyi, tigwiritsa ntchito mawu oti MCPCB kuti tipewe kusamveka bwino.

Ma MCPCB amapangidwa ndi zigawo zoteteza kutentha, mbale zachitsulo, ndi zojambulazo zamkuwa. Maupangiri enanso / malingaliro a Metal Core (Aluminiyamu ndi Mkuwa) Mabodi Ozungulira Osindikizidwa amapezeka mukafunsidwa; Lumikizanani ndi YMSPCB pa kell@ymspcb.com.kapena Woimira Malonda anu kuti mufunse zambiri.

zitsulo pakati pcb

 YMS Multi Layers  Zitsulo pakati PCB kuthekera kopanga:

YMS Multi Layers Metal core PCB kupanga luso lachidule

Kudzera Kudzaza Njira Njirayo imadzazidwa ndikudzazidwa ndi epoxy yoyendetsa kapena yosakhazikika kenako yophimbidwa ndikuphimbidwa (VIPPO)
Mkuwa wodzazidwa, wodzazidwa ndi siliva
Kulembetsa ± 4mil
Solder Chigoba Green, Red, Yellow, Blue, White, Black, Pepo, Matte Black, Matte wobiriwira.etc.

 Zifukwa zazikulu zogwiritsira ntchito matabwa amkuwa

1. Kutentha kwabwino:

Pakali pano, ambiri  2 wosanjikiza bolodi  ndi  multilayer matabwa  ndi mwayi mkulu kachulukidwe ndi mkulu mphamvu, koma kutentha mpweya ndi kovuta kukhala. Zinthu zoyambira za PCB monga FR4, CEM3 ndizoyendetsa bwino kutentha, kutchinjiriza kumakhala pakati pa zigawo, ndipo kutulutsa kwa kutentha sikungatuluke. Kutentha kwapakati pazida zamagetsi sikungatheke kumapangitsa kuti pakhale kutentha kwakukulu kwa zipangizo zamagetsi. Koma kuchita bwino kwa kutentha kwapakati pa PCB yachitsulo kumatha kuthetsa vutoli.

2. Kukhazikika kwa dimensional:

Metal core PCB mwachiwonekere ndi yokhazikika kwambiri kukula kwake kuposa matabwa osindikizidwa a zipangizo zotetezera. Aluminium base board  ndi aluminiyamu masangweji bolodi akuwotcha kuchokera 30 ℃ mpaka 140 ~ 150 ℃, kukula kwake kusintha kwa 2.5 ~ 3.0%.

3. Chifukwa china:

Copper base board imakhala ndi chitetezo ndipo imalowa m'malo mwa brittle ceramic substrate, kotero imatha kukhala yotsimikiza kugwiritsa ntchito ukadaulo wokwera pamwamba kuti muchepetse malo enieni a PCB. Copper base board ilowa m'malo mwa radiator ndi zinthu zina, imathandizira kukana kutentha ndi magwiridwe antchito azinthu ndipo imachepetsa ndalama zopangira ndi ndalama zogwirira ntchito.

Mungakonde:

1, Makhalidwe a ntchito ya aluminium PCB

2, Mkuwa plating ndondomeko PCB kunja wosanjikiza (PTH)

3, Copper clad mbale ndi zotayidwa gawo lapansi zosiyana zinayi zazikulu
