Complete Guide paAluminium Nitride PCB

Chii chinonzi Aluminium Nitride PCB (AlN PCB)?

MaPCB eAluminium nitride (AlN) anoreva rudzi rwakasiyana rwePCB yeceramic yakagadzirwa uchishandisa aluminium nitride (AlN) ceramic substrates sechinhu chinodzivirira kupisa panzvimbo pezvinhu zvemazuva ano zvakaita seFR-4. Sechinhu chakakosha chinosimbiswa mutekinoroji yemazuva ano yePCB yeceramic , AlN inopa mabhenefiti akasiyana emagetsi anoshanda zvakanyanya.

MuAlN PCBs, iyo aluminium nitride ceramic inoshanda seyakakosha dielectric layer inotsigira conductive mhangura yedunhu maseketi. Izvi zvakasiyana nemaPCB akajairwa anoshandisa fiberglass yakasimbiswa epoxy composites seFR-4 seyo insulating substrate. Iwo conductive layers anowanzo kuisirwa paAlN ceramic pamusoro kuburikidza nenzira dzakaita sedhinda rekudhinda, nhete firimu deposition kana yakananga bond copper (DBC). Makomba anogona kuumbwa muAlN substrate kugonesa conductive vias pakati pematanho.

Kuenzaniswa neorganic laminates, AlN ceramic inopa yepamusoro yekupisa conductivity se insulator uku ichichengetedza mutsara wepedyo kune silicon coefficient yekuwedzera kupisa. Izvi zvinoita kuti maAlN PCB akwanise kubata tembiricha yepamusoro uye mazinga emagetsi pasina kukundikana. Mutengo wakakwira wealuminium nitride ceramic material zvinoreva kuti maAlN PCBs anowanzo shandiswa zvakasarudzwa pakuda maapplication kwete kutsiva akazara mabhodhi eFR-4.

Mashandisirwo akajairika anosanganisira magetsi emagetsi, ma LED anopenya zvakanyanya, uye magetsi emuchadenga. Pakati pezvinhu zvakasiyana zveceramic, Alumina PCBs inowanzo shandiswa pakugadzirisa zvinhu zvisingadhuri, nepo AlN ichisarudzwa nekuda kwekupisa kwayo kwakanyanya. Kuti uwane rumwe ruzivo rwekuti mabhodhi aya akagadzirwa sei, maitiro edu ekugadzira maPCB eceramic anotsanangura danho rega rega rekugadzira uye matekinoroji anobatanidzwa.

Muchidimbu, AlN PCBs ikirasi chaiyo yeceramic PCBs iyo inokwidziridza iyo yakasarudzika mabhenefiti ealuminium nitride substrates yekudziya kwekutonga, kushivirira kwekushisa uye kuvimbika, kunyanya munzvimbo dzakaoma dzekushanda.

Zvikonzero nei uchifanira kushanda neAluminium Nitride PCB

Kushanda neAluminium Nitride (AlN) PCBs kunopa zvikonzero zvakati wandei zvinomanikidza, kunyanya mumashandisirwo uko kutonga kwemafuta, kuita kwepamusoro-soro, uye kuvimbika kwakakosha. Heano zvimwe zvikonzero zvakakosha zvekufunga kushandisa AlN PCBs:

Nekunyatsogadzirisa izvi zvinotariswa zvekugadzira, unogona kubatanidza kugona kwakazara kweAluminium Nitride PCBs uye kugadzira zvemagetsi masisitimu anokunda mukupisa kwekutonga, kuita kwepamusoro-soro, uye kuvimbika, uku uchidzikisa matambudziko ane chekuita nekugadzira.

Kugadzira AlN PCB

Iyo yekugadzira maitiro eAluminium Nitride (AlN) PCBs inosanganisira akati wandei akakosha matanho, kubva pakugadzira substrate kusvika pakubatanidzwa kwedzimba. Aya matanho anokwidziridza yakasarudzika zvivakwa zveAlN, senge yakasarudzika yekupisa conductivity, kugadzira yakakwirira-inoshanda edunhu mabhodhi. Heino mhedziso yezvakawanda maitiro:

1.Substrate Manufacturing

• AlN poda inoumbwa kuita billet kuburikidza nechando isostatic pressing (CIP). Kuita uku kunosanganisira kudzvanya iyo AlN poda kuita dense, cylindrical chimiro uchishandisa hydraulic pressure.
• Binder zvinhu zvinowedzerwa kune AlN poda kuti ifambise kubata kwezvinhu panguva yekuumba uye kunyura.
• The shaped billet inosiiwa patembiricha iri pamusoro pe1800°C mumhepo yenitrogen. Sintering inosanganisa iyo AlN poda zvimedu pamwechete, kugadzira yakazara dense ceramic substrate ine yakanakisa yekupisa zvivakwa.
• Iyo AlN bhodhi yakanyatso kuvhurika uye yakakwenenzverwa pasi kusvika kune yakatsanangurwa ukobvu, ichiva nechokwadi chenzvimbo yakatsetseka uye yakafanana kune inozogadziriswa.

2.Metallization

• Mapepa akakora emufirimu ane zvinhu zvakaita se tungsten kana molybdenum anodhindirwa skrini paAlN substrate kugadzira matunhu edunhu. Izvi zvakakora zvemufirimu zvinhu zvinozivikanwa nekusimba uye kugona kushingirira tembiricha yepamusoro.
• Masimbi emufirimu matete akadai semhangura kana goridhe anogona zvakare kuiswa pane substrate uchishandisa matekiniki akaita senge sputtering kana plating.
• Kupisa kwepamusoro-tembiricha kunoshandiswa kubatanidza iyo metallization kune AlN substrate, kuve nechokwadi chekubatana kwemagetsi kwakavimbika.

3.Multilayer Buildup

• Kune maPCB akaomarara, akawanda maAlN substrates (mbiri-mativi mabhodhi) anogona kurongedzerwa nekumisikidzwa pamwechete uchishandisa anonamira mafirimu. Izvi zvinobvumira kugadzirwa kwemultilayer PCBs.
• Vias uye kuburikidza nemakomba anoboorwa-laser kuburikidza neakaturikidzana akaturikidzana uye akazadzwa nemabatiro ekuitisa, achigadzira kubatanidza kwemagetsi pakati pematanho.
• Mune zvimwe zviitiko, mapofu uye akavigwa vias anogona kushandiswa kubatanidza yemukati akaturikidzana, achipa mamwe maitirwo sarudzo.

4.Housing Integration

• AlN substrates yakanyatsokodzera kusungirirwa kwakananga mumapakeji ehermetic, uko zvinhu zvemagetsi zvakanamirwa kuchengetedzwa.
• Zvisimbiso senge epoxy, brazing zvinhu, kana girazi zvinogona kushandiswa kugadzira hermetic zvisimbiso, kuve nechokwadi chekuvimbika kwemagetsi akavharirwa.

Maitiro ekugadzira eAlN PCB anogovera mamwe akafanana nematanho anoshandiswa kune alumina ceramic mabhodhi. Nekudaro, AlN PCBs inopa yakanyanya kukwirisa yekupisa conductivity, ichiita kuti ive yakanakira maapplication uko kwakakosha kutonga kwekupisa kwakakosha. Uku kusanganisa kwakasarudzika kwezvivakwa kunobvumira maAlN PCBs kuti aite zvakanaka mumasisitimu emagetsi epamusoro-soro, kunyanya mumaindasitiri akadai seaerospace, nharembozha, uye yakakwirira-frequency RF application.

Kuenzanisa kweAluminium Nitride, Alumina, uye FR-4

Kana zvasvika pakusarudza iyo yakakodzera zvinhu zveakadhindwa edunhu mabhodhi (PCBs) kana mamwe maapplication emagetsi, kunzwisisa zvimiro zvechimwe nechimwe chinhu kwakakosha. Aluminium Nitride, Alumina, uye FR-4 zvinhu zvitatu zvinowanzo shandiswa, imwe neimwe iine seti yayo yehunhu. Heino kuenzanisa kwakadzama kwakavakirwa pane akati wandei paramita:

Kuongorora Kuenzanisa:

• Thermal Conductivity: AlN ine yakanyanya kukwira yekupisa yekupisa kana ichienzaniswa neAlumina neFR-4, ichiita kuti ive yakanakira maapplication anoda yakanakisa kupisa kupisa, senge yakakwira-inoshanda magetsi uye LED mwenje.
• Dielectric Constant: AlN ine dielectric yakaderera zvishoma pane Alumina asi yakakwirira kupfuura FR-4. Iyo yakaderera dielectric inogarogaro farira mune yakakwira-frequency application sezvo inogona kuderedza kurasikirwa kwechiratidzo.
• Dielectric Simba: AlN inopa yakakwira dielectric simba kana ichienzaniswa neAlumina, ichiratidza zvirinani zvivakwa zviri pasi pemhepo yakakwira, asi huwandu hunopindirana neFR-4.
• Kupisa Kwepasi: AlN inomira tembiricha yakakwira zvakanyanya kana ichienzaniswa neFR-4, uye yakakwira zvishoma pane Alumina, zvichiita kuti ive yakakodzera kune yakakwirira-tembiricha nharaunda.
• Coefficient of Thermal Expansion (CTE): AlN ine CTE yakaderera kana ichienzaniswa neyese Alumina neFR-4, zvichireva shanduko shoma nekuchinja kwetembiricha, izvo zvakakosha pakuchengetedza kuvimbika kwechimiro mukupisa bhasikoro maapplication.
• Flexural Strength: AlN ine simba zvishoma pane Alumina uye yakasimba zvakanyanya kupfuura FR-4, zvichiratidza kuti inogona kumirisana nepamusoro mechanicha kushushikana, izvo zvakakosha mumashandisirwo akaomarara.

Aluminium Nitride (AlN) yepamusoro-soro maererano nekupisa kwekushisa, kuramba tembiricha, uye simba remuchina, zvichiita kuti ive sarudzo yakanaka kune yakakwirira-simba uye yakakwirira-tembiricha maapplication apo zvechinyakare zvinhu seFR-4 zvinodonha. Nekudaro, izvi zvivakwa zvakakwidziridzwa zvinouya nemutengo unoreva, uye sarudzo pakati peAlN, Alumina, uye FR-4 zvinoenderana nezvinodiwa chaizvo zvekushandisa, zvinosanganisira nharaunda dzekushanda, zvinodiwa nemagetsi, kushushikana kwemagetsi, uye zvimhingamipinyi zvebhajeti.
