Chii chinonzi Multi Layers MCPCB?

Iyo Metal Core Printed Circuit Board (MCPCB) , inozivikanwawo sePCB inopisa pcb simbi inotsigirwa nePCB, imhando yePCB ine zvinhu zvesimbi sehwaro hwayo hwechikamu chekuparadzira kupisa chebhodhi. Iyo gobvu simbi (inenge nguva dzose aruminiyamu kana mhangura) inovhara 1 divi rePCB. Metal core inogona kureva simbi, ingave iri pakati pane imwe nzvimbo kana kumashure kwebhodhi. Chinangwa chepakati cheMCPCB ndechekudzosera kupisa kure kubva kune zvakakosha bhodhi zvikamu uye kune zvisinganyanyi kukosha senge simbi heatsink inotsigira kana simbi simbi. Nheyo dzesimbi muMCPCB dzinoshandiswa seimwe nzira kune FR4 kana CEM3 mabhodhi.

Simbi yesimbi yakadhindwa yedunhu bhodhi (MCPCB) inozivikanwawo seyekupisa PCB, inosanganisa simbi sehwaro hwayo kupesana neyechinyakare FR4, yekupisa yekuparadzira chidimbu chebhodhi. Kupisa kunowedzera nekuda kwezvimwe zvikamu zvemagetsi panguva yekushanda kwebhodhi. Chinangwa chesimbi ndechekubvisa kupisa uku kubva kune zvakakosha bhodhi zvikamu uye kuenda kunzvimbo dzisina kukosha dzakadai sesimbi heatsink inotsigirwa kana simbi yesimbi. Nekudaro, maPCB aya anokodzera kutonga kwekupisa.

Mune multilayer MCPCB, iwo akaturikidzana achagoverwa zvakaenzana padivi rega rega resimbi musimboti. Semuyenzaniso, mune 12-layer board, iyo simbi core ichange iri pakati ne6 ma layer kumusoro uye matanhatu pasi.

MCPCBs inonziwo insulated metallic substrate (IMS), insulated simbi PCBs (IMPCB), thermal clad PCBs, uye simbi-yakapfeka PCBs. Muchinyorwa chino, tichange tichishandisa acronym MCPCB kudzivirira kusanzwisisika.

Iwo MCPCBs anoumbwa neanopisa anodzivirira akaturikidzana, marata esimbi, uye simbi yemhangura foil. Mamwe mazano ekugadzira / mazano eMetal Core (Aluminium neCopper) Yakadhindwa Circuit Boards inowanika pakukumbira; bata YMSPCB pa kell@ymspcb.com.kana Sales Representative yako kuti ubvunze zvakawanda.

YMS Multi Layers Simbi musimboti pcb kugadzira kugona:

Zvikonzero zvikuru zvekushandisa mhangura base mapuranga

1. Kupisa kwakanaka kwekupisa:

Parizvino, akawanda 2 layer board uye multilayer board ane mukana wepamusoro density uye simba rakawanda, asi kuburitsa kupisa kwakaoma kuve. Zvakajairwa PCB base zvinhu zvakaita seFR4, CEM3 haina kunaka conductor yekupisa, insulation iri pakati pematanho, uye kupisa kuburitsa hakugone kubuda. Kupisa kwenzvimbo yemidziyo yemagetsi hakugone kubviswa kuchaita kuti kutadza kwepamusoro-kupisa kwezvikamu zvemagetsi. Asi iyo yakanaka kupisa kupisa kuita kwesimbi yepakati PCB inogona kugadzirisa dambudziko iri rekupisa kupisa.

2. Dimensional kugadzikana:

Metal musimboti PCB zviri pachena kuti yakanyanya kugadzikana muhukuru kupfuura akadhindwa mabhodhi emidziyo inodzivirira. Aluminium base board uye aluminium sandwich board iri kupisa kubva pa30 ℃ kusvika 140 ~ 150 ℃, saizi yaro inoshanduka ye2.5 ~ 3.0%.

3. Chimwe chikonzero:

Copper base board ine shielding effect uye inotsiva brittle ceramic substrate, saka inogona kuzorora kuvimbiswa kushandisa pamusoro pekuisa tekinoroji kuderedza iyo chaiyo inoshanda nzvimbo yePCB. Copper base board inotsiva radiator uye zvimwe zvinhu, inovandudza kupisa kwekupisa uye kuita kwemuviri kwezvigadzirwa uye inoderedza mutengo wekugadzira uye mutengo wevashandi.
