Kupanga matabwa a ceramic ogwiritsira ntchito kutentha kwakukulu

Mu positi iyi yabulogu, tikambirana zina zofunika zomwe mainjiniya ndi okonza mapulani amayenera kukumbukira kuti awonetsetse kuti ma board ozungulira a ceramic akuyenda bwino.

M'zaka zaposachedwa, matabwa a ceramic adakopa chidwi chifukwa cha kukana kwawo kutentha komanso kudalirika. Amadziwikanso kuti ma ceramic printed circuit board (PCBs), matabwawa amapangidwa kuti athe kupirira kutentha kwambiri komwe kumakumana ndi kutentha kwambiri. Kuchokera ku mafakitale oyendetsa ndege ndi magalimoto kupita ku magetsi ndi kuunikira kwa LED, matabwa ozungulira a ceramic atsimikizira kuti ndi osintha masewera.

1. Kusankha kwazinthu: Kusankha zinthu zadothi zoyenera ndizofunikira kwambiri popanga matabwa ozungulira omwe amatha kutentha kwambiri.Zida za Ceramic monga aluminium oxide (Al2O3), aluminium nitride (AlN), ndi silicon carbide (SiC) zimawonetsa kusinthasintha kwabwino kwamafuta komanso kutsekemera kwamagetsi. Amakhalanso ndi kukulitsa kwamafuta ochepa, komwe kumalepheretsa matabwa ozungulira kuti asaphwanyike kapena kupunduka chifukwa cha kusinthasintha kwa kutentha kwambiri. Posankha zinthu zoyenera za ceramic, opanga amatha kutsimikizira kudalirika komanso moyo wautali wa matabwa awo ozungulira m'malo otentha kwambiri.

2. Thermal Management: Kutentha kwakukulu kumatha kusokoneza magwiridwe antchito a zida zamagetsi.Kuti muchepetse chiwopsezo cha kutentha kwambiri, njira zoyenera zowongolera kutentha ziyenera kuphatikizidwa pamapangidwe a matabwa a ceramic. Izi zikuphatikizapo kugwiritsa ntchito masinki otentha, mpweya wolowera, ndi zoziziritsira kuti zithetse kutentha. Kuyerekeza ndi kuyezetsa kwa kutentha kungathandize kuzindikira malo omwe angatenthe ndi kukulitsa magwiridwe antchito a board.

3. Kuyika kwa zigawo: Kuyika kwa zigawo pa bolodi la dera la ceramic kudzakhudza kwambiri kutentha kwake.Zida zamphamvu kwambiri ziyenera kuyikidwa bwino kuti zichepetse kutentha ndikuwonetsetsa kuti zigawika pagulu lonse. Kutalikirana pakati pa zigawo ziyeneranso kuganiziridwa mosamala kuti pakhale kutentha kwabwino.

4. Kufufuza kochititsa chidwi ndi kapangidwe kake: Ma board a Ceramic amafunikira kunyamula kwamakono kuposa ma PCB achikhalidwe.Nkofunika kuonetsetsa kuti kuda conductive ndi vias lakonzedwa kusamalira apamwamba mafunde popanda kutenthedwa kapena kuchititsa madontho voteji. Kufufuza m'lifupi ndi makulidwe akuyenera kutsimikiziridwa mosamala kuti achepetse kukana komanso kukulitsa kutayika kwa kutentha.

5. Ukadaulo wowotcherera: Zolumikizira za solder ziyenera kulimbana ndi kutentha kwambiri ndikukhalabe kukhulupirika, makamaka pakutentha kwambiri.Kusankha zinthu zoyenera zosungunuka zosungunuka ndikugwiritsa ntchito njira zoyenera zogulitsira (monga reflow kapena wave soldering) ndizofunikira kuti zitsimikizire kulumikizana kodalirika ndikuchepetsa kupsinjika kwa kutentha.

6. Kuganizira za chilengedwe: Kutentha kwakukulu nthawi zambiri kumatsagana ndi mikhalidwe yovuta ya chilengedwe, monga chinyezi, chinyezi, mankhwala, kapena kugwedezeka.Okonza ayenera kuganizira izi ndikusankha zipangizo za ceramic ndi zokutira zotetezera zomwe zingathe kupirira zovuta zoterezi. Kuyesedwa kwa chilengedwe ndi chiphaso kumatsimikizira kudalirika kwa bolodi pansi pa zochitika zenizeni.

Powombetsa mkota

Kupanga matabwa a ceramic ogwiritsira ntchito kutentha kwakukulu kumafuna kusamala kwambiri posankha zinthu, kasamalidwe ka kutentha, kuyika chigawo, ma conductive, njira zogulitsira, ndi zinthu zachilengedwe.Poganizira izi ndikugwiritsa ntchito njira zabwino kwambiri, mainjiniya ndi okonza amatha kupanga matabwa omwe amapereka magwiridwe antchito apamwamba, odalirika, komanso moyo wautali m'malo otentha kwambiri. Chifukwa chake ngakhale mukupanga makina apakompyuta azamlengalenga, zamagalimoto, kapena bizinesi ina iliyonse yomwe imafuna kukana kutentha kwambiri, kuyika nthawi ndi khama popanga ma board a ceramic mosakayika kudzabala zipatso.
