Chikamu Chekutanga: Chii chinonzi Aluminium PCB?
Aluminium substrate imhando yesimbi-based copper-clad board ine yakanakisa kupisa kupisa kushanda.Kazhinji, bhodhi rine divi rimwe chete rinoumbwa nezvikamu zvitatu: dunhu redunhu (copper foil), iyo insulating layer, uye simbi base layer.Kune epamusoro-magumo ekushandisa, kune zvakare maviri-mativi madhizaini ane chimiro chedunhu layer, insulating layer, aluminium base, insulating layer, uye circuit layer.Nhamba diki yezvishandiso inosanganisira akawanda-layer mabhodhi, ayo anogona kugadzirwa nekubatanidza akajairwa akawanda-layer mabhodhi ane insulating layer uye mabhesi ealuminium.
Single-sided aruminiyamu substrate: Iyo ine imwechete layer ye conductive pateni layer, insulating material, uye aluminium plate (substrate).
Kaviri-mativi aruminiyamu substrate: Inosanganisira maviri akaturikidzana e conductive pateni layer, insulating material, uye aluminium plate (substrate) akaturikidzana.
Multi-layer akadhindwa aruminiyamu redunhu bhodhi: Zviri akadhindwa redunhu bhodhi rakagadzirwa laminating uye bonding matatu kana kupfuura akaturikidzana conductive patani akaturikidzana, insulating zvinhu, uye aruminiyamu ndiro (substrate) pamwe chete.
Yakakamurwa nepamusoro nzira dzekurapa:
Goridhe-yakaputirwa bhodhi (Kemikari goridhe rakatetepa, Kemikari gobvu goridhe, Sarudzo yegoridhe plating)
Chikamu Chechipiri: Aluminium Substrate Kushanda Nheyo
Zvishandiso zvemagetsi zviri pamusoro-zvakaiswa pamusoro wedunhu layer.Kupisa kunogadzirwa nemidziyo panguva yekushanda kunoitwa nekukurumidza kuburikidza neiyo insulating layer kune simbi base layer, iyo inobva yabvisa kupisa, ichiwana kupisa kwekupisa kwemidziyo.
Kuenzaniswa neyakajairwa FR-4, aluminium substrates inogona kuderedza kupisa kwekupisa, ichivaita makondakita ekupisa.Kuenzaniswa neakakora-firimu Ceramic maseketi, ivo zvakare vane epamusoro mechanicha zvivakwa.
Pamusoro pezvo, aluminium substrates ine zvinotevera zvakasarudzika zvakanakira:
-Kutevedza zvinodiwa neRoHs
- Zvirinani kuchinjika kune SMT maitiro
-Kubata kunoshanda kwekupisa kwekupisa mudhizaini yekudzikisa tembiricha yekushandisa, kuwedzera hupenyu, kuwedzera simba density uye kuvimbika.
-Kudzikisira mukuungana kwemasinki ekupisa uye mamwe mahardware, zvinosanganisira thermal interface zvinhu, zvichikonzera diki chigadzirwa vhoriyamu uye yakaderera hardware uye mutengo wegungano, uye musanganiswa wakakwana wesimba nekudzora maseketi.
-Kutsiviwa kweasina kusimba ceramic substrates yekuvandudzwa kwemakanika kusimba
Chikamu Chechitatu: Kuumbwa kweAluminium Substrates
1. Circuit Layer
Dunhu redunhu (kazhinji rinoshandisa electrolytic copper foil) inomisikidzwa kuti igadzire masekete akadhindwa, anoshandiswa kubatanidza chikamu uye kubatana.Kuenzaniswa neyakajairwa FR-4, ine ukobvu hwakafanana uye upamhi hwemutsara, aluminium substrates inogona kutakura mafungu epamusoro.
2. Insulating Layer
Iyo insulating layer ndiyo yakakosha tekinoroji mualuminium substrates, inoshandira zvakanyanya kunamatira, kumisa, uye kupisa conduction.Iyo insulating layer yealuminium substrates ndiyo inonyanya kukosha yekupisa inodzivirira mumagetsi module zvimiro.Zvirinani kupisa kwekushisa kweiyo insulating layer inofambisa kupararira kwekupisa kunogadzirwa panguva yekushanda kwechishandiso, zvichitungamira kune yakaderera tembiricha yekushanda, yakawedzera module simba rekutakura, saizi yakaderedzwa, yakawedzera hupenyu, uye yakakwira simba rekubuda.
3. Metal Base Layer
Sarudzo yesimbi yechigadziko chesimbi inodzika inotsamira pakufunga kwakadzama kwezvinhu zvakaita sesimbi base coefficient yekuwedzera kwekupisa, thermal conductivity, simba, kuoma, huremu, mamiriro epasi, uye mutengo.
Chikamu Chechina: Zvikonzero Zvekusarudza Aluminium Substrates
1. Kupisa Kupisa
Mabhodhi mazhinji ane mativi maviri uye akawanda-layer ane dhizaini uye simba, zvichiita kuti kupisa kupisa kuve kwakaoma.Zvakajairwa substrate zvinhu zvakaita seFR4 neCEM3 hazvina kunaka maconductor ekupisa uye ane inter-layer insulation, zvichikonzera kusakwana kwekupisa kupisa.Aluminium substrates inogadzirisa iyi nyaya yekupisa kupisa.
2. Thermal Kuwedzera
Kuwedzera kwekupisa uye kudonhedza kunoenderana nezvinhu, uye zvinhu zvakasiyana zvine macoefficients akasiyana ekuwedzera kwekupisa.Aluminium-based akadhindwa mabhodhi anogadzirisa zvinobudirira nyaya dzekupisa kupisa, kurerutsa dambudziko remhando dzakasiyana dzekuwedzera kupisa pazvikamu zvebhodhi, kuvandudza kusimba kwese uye kuvimbika, kunyanya mumashandisirwo eSMT (Surface Mount Technology).
3. Dimensional Kugadzikana
Aluminium-yakavakirwa mabhodhi akadhindwa akanyanya kugadzikana maererano nehukuru kana ichienzaniswa neyakavharidzirwa zvinhu zvakadhindwa mabhodhi.Dimensional shanduko yealuminium-based printed boards kana aluminium core board, inopisa kubva pa30°C kusvika 140-150°C, i2.5-3.0%.
4. Zvimwe Zvikonzero
Aluminium-based printed boards ane shielding effects, inotsiva brittle ceramic substrates, yakakodzera for surface mounting tekinoroji, inoderedza inobudirira nzvimbo yemapuranga akadhindwa, kutsiva zvinhu zvakaita semadhishi ekupisa kuti chiwedzere kusawirirana nekupisa kwechigadzirwa uye zvimiro zvemuviri, uye kuderedza mutengo wekugadzira nekushanda.
