Kugadzira ceramic circuit mabhodhi epamusoro tembiricha yekushandisa

Mune ino blog post, isu tichakurukura zvimwe zvakakosha izvo mainjiniya nevagadziri vanofanirwa kuchengeta mupfungwa kuti ive nechokwadi chekubudirira dhizaini uye kuita kweceramic redunhu mabhodhi.

Mumakore achangopfuura, Ceramic redunhu mapuranga akakwezva kutarisa nekuda kwekunaka kwavo kupisa kupisa uye kuvimbika. Iyo inozivikanwawo seceramic yakadhindwa edunhu mabhodhi (PCBs), mabhodhi aya akagadzirirwa chaizvo kutsungirira tembiricha yakanyanyisa inowanzo sangana mukupisa-kupisa kwekushandisa. Kubva kuAerospace uye maindasitiri emotokari kumagetsi emagetsi uye kuvhenekesa kwe LED, mapuranga eceramic redunhu aratidza kuve mutambo wekuchinja.Zvisinei, kugadzira zvedongo redunhu mapuranga epamusoro tembiricha zvikumbiro zvinoda kunyatsotariswa zvinhu zvakawanda.

Ceramic circuit boards design

 

1. Kusarudzwa kwezvinhu: Kusarudza iyo yakakodzera ceramic zvinhu kwakakosha pakugadzira yakakwirira-tembiricha inodzivirira edunhu mabhodhi.Ceramic zvinhu zvakaita sealuminium oxide (Al2O3), aluminium nitride (AlN), uye silicon carbide (SiC) inoratidza yakanakisa yekupisa conductivity uye magetsi ekudzivirira. Ivo zvakare vane yakaderera thermal kuwedzera, izvo zvinodzivirira edunhu mabhodhi kubva pakutsemuka kana kukanganisa nekuda kwekunyanya kupisa kwekushisa. Nekusarudza iyo yakakodzera ceramic zvinhu, vagadziri vanogona kuve nechokwadi chekuvimbika uye hupenyu hurefu hwemabhodhi avo edunhu munzvimbo dzepamusoro-tembiricha.

2. Thermal Management: Kupisa kwepamusoro kunogona kukanganisa kushanda kwezvinhu zvemagetsi.Kuti uderedze njodzi yekupisa, nzira dzakakodzera dzekudziya dzekupisa dzinofanirwa kuisirwa mukugadzirwa kweceramic circuit board. Izvi zvinosanganisira kushandisa masingi ekupisa, mavhavha, uye mapedhi ekutonhodza kuti anyatso bvisa kupisa. Thermal simulation uye kuyedzwa kunogona kubatsira kuona zvinogona kupisa nzvimbo uye kukwidziridza bhodhi rinopisa.

3. Component placement: Kuiswa kwezvikamu pane ceramic circuit board kuchakanganisa zvakanyanya kupisa kwayo.High-simba zvikamu zvinofanirwa kuiswa zvine hungwaru kuti zvideredze kupisa uye kuve nechokwadi kunyangwe kugoverwa mukati mebhodhi. Kupatsanurana pakati pezvikamu kunofanirwawo kunyatsotariswa kuitira zviri nani kupisa kupisa.

4. Conductive trace uye kuburikidza nedhizaini: Ceramic redunhu mabhodhi kazhinji inoda yakakwirira ikozvino kutakura kugona kupfuura yechinyakare PCBs.Zvakakosha kuve nechokwadi chekuti conductive traces uye vias zvakagadzirirwa kubata yakakwirira mafungu pasina overheating kana kukonzera voltage madonhwe. Kutsvaga hupamhi uye ukobvu kunofanirwa kunyatso temwa kudzikisa kuramba uye kuwedzera kupisa kupisa.

5. Welding tekinoroji: Solder majoini anofanirwa kumira kutonhora kwakanyanya uye kuchengetedza kutendeseka kwavo, kunyanya mukupisa-kupisa kwekushandisa.Kusarudza iyo chaiyo yakakwira melting point soldering zvinhu uye kushandisa nzira dzakakodzera dzekutengesa (senge reflow kana wave soldering) zvakakosha kuti uve nechokwadi chekubatana kwakavimbika uye kuderedza kushushikana kwekupisa.

6. Mafungiro ezvakatipoteredza: Kushandiswa kwepamusoro-tembiricha kunowanzo kuperekedzwa nemamiriro ekunze akashata, akadai sehunyoro, unyoro, makemikari, kana kuzununguka.Vagadziri vanofanira kufunga nezvezvinhu izvi uye sarudza ceramic zvinhu uye machira ekudzivirira anogona kutsungirira matambudziko akadaro. Kuyedzwa kwezvakatipoteredza uye chitupa kunovimbisa kuvimbika kwebhodhi pasi pemamiriro epasirese.

Muchidimbu

Kugadzira mapuranga eceramic edunhu repamusoro-tembiricha kunyorera kunoda kutarisisa kusarudzwa kwezvinhu, kutonga kwekupisa, kuiswa kwechikamu, maitiro ekufambisa, matekiniki ekutengesa, uye zvakatipoteredza zvinhu.Nekutarisisa zvinhu izvi uye nekushandisa zvakanakisa maitiro, mainjiniya nevagadziri vanogona kugadzira mabhodhi anopa kuita kwepamusoro, kuvimbika, uye hupenyu hurefu munzvimbo dzekupisa kwakanyanya. Saka kunyangwe iwe uri kugadzira masisitimu emagetsi emuchadenga, mota, kana chero imwe indasitiri inoda yakanyanya kupisa tembiricha, kuisa nguva nesimba mukugadzira nemazvo mabhodhi edunhu receramic pasina mubvunzo zvinounza zvibereko.
