Ukuklama amabhodi wesifunda se-ceramic wezinhlelo zokusebenza zokushisa okuphezulu

Kulokhu okuthunyelwe kwebhulogi, sizoxoxa ngezinto eziyisisekelo onjiniyela nabaqambi okudingeka bazikhumbule ukuze baqinisekise ukuklama okuphumelelayo nokusebenza kwamabhodi esekethe e-ceramic.

Eminyakeni yamuva, amabhodi wesifunda se-ceramic adonse ukunaka ngenxa yokumelana nokushisa kwawo okuhle kakhulu nokuthembeka. Aziwa nangokuthi amabhodi esekethe ephrintiwe e-ceramic (ama-PCB), lawa mabhodi aklanyelwe ngqo ukumelana nezinga lokushisa elidlulele elivame ukuhlangana nalo ezinhlelweni zezinga lokushisa eliphezulu. Kusukela ezimbonini ze-aerospace kanye nezimoto kuya kumandla kagesi kanye nokukhanyisa kwe-LED, amabhodi wesifunda se-ceramic afakazele ukuthi ashintsha umdlalo.Nokho, ukuklama amabhodi wesifunda se-ceramic wezinhlelo zokusebenza zokushisa okuphezulu kudinga ukucatshangelwa ngokucophelela kwezici eziningana.

1. Ukukhetha impahla: Ukukhetha impahla ye-ceramic efanele ibalulekile ekuklameni amabhodi esekethe amelana nokushisa okuphezulu.Izinto ze-Ceramic ezifana ne-aluminium oxide (Al2O3), i-aluminium nitride (AlN), ne-silicon carbide (SiC) zibonisa ukuqhutshwa kokushisa okuhle kakhulu kanye nokufakwa kukagesi. Futhi banokunwebeka okuphansi kwe-thermal, okuvimbela amabhodi wesifunda ukuthi angaqhekeki noma awonakele ngenxa yokushintsha kwezinga lokushisa okudlulele. Ngokukhetha izinto ezifanele ze-ceramic, abaklami bangaqinisekisa ukwethembeka nokuphila isikhathi eside kwamabhodi wabo wesifunda ezindaweni ezishisa kakhulu.

2. Ukuphathwa Kokushisa: Amazinga okushisa aphezulu angaba nomthelela omubi ekusebenzeni kwezingxenye ze-elekthronikhi.Ukuze unciphise ingozi yokushisa ngokweqile, izindlela ezifanele zokuphatha ukushisa kufanele zifakwe ekwakhiweni kwamabhodi wesifunda se-ceramic. Lokhu kuhlanganisa ukusebenzisa osinki bokushisa, ama-vents, namaphedi okupholisa ukuze kuqedwe ukushisa ngempumelelo. Ukulingisa okushisayo nokuhlola kungasiza ukukhomba izindawo ezishisayo ezingaba khona futhi kuthuthukise ukusebenza okushisayo kwebhodi.

3. Ukubekwa kwengxenye: Ukubekwa kwezingxenye ebhodini lesifunda se-ceramic kuzothinta kakhulu ukumelana kwayo nezinga lokushisa.Izingxenye zamandla aphezulu kufanele zibekwe ngendlela ehlelekile ukuze kuncishiswe ukugxila kokushisa futhi kuqinisekiswe ukusatshalaliswa okulinganayo kulo lonke ibhodi. Isikhala phakathi kwezingxenye kufanele futhi kucatshangelwe ngokucophelela ukuze kukhishwe ukushisa okungcono.

4. Ukulandelela okuqhutshwayo nangokuklama: Amabhodi esekethe e-Ceramic ngokuvamile adinga amandla okuphatha amanje aphezulu kunama-PCB endabuko.Kubalulekile ukuqinisekisa ukuthi iminonjana conductive kanye vias yakhelwe ukusingatha imisinga ephakeme ngaphandle kokushisa ngokweqile noma okubangela ukwehla kwamandla kagesi. Ububanzi bokulandelela nokujiya kufanele kunqunywe ngokucophelela ukuze kuncishiswe ukumelana nokwandisa ukuqeda ukushisa.

5. Ubuchwepheshe be-Welding: Amalunga e-Solder adinga ukumelana nokushisa okuphezulu futhi agcine ubuqotho bawo, ikakhulukazi ekusetshenzisweni kokushisa okuphezulu.Ukukhetha into efanele yokuncibilikisa indawo ephezulu kanye nokusebenzisa izindlela ezifanele zokunamathisela (ezifana nokugeleza kabusha noma i-wave soldering) kubalulekile ekuqinisekiseni ukuxhumana okuthembekile kanye nokunciphisa ukucindezelwa okushisayo.

6. Ukucatshangelwa kwemvelo: Izinga lokushisa eliphezulu livame ukuhambisana nezimo zemvelo ezinzima, ezinjengomswakama, umswakama, amakhemikhali, noma ukudlidliza.Abaqambi kufanele bacabangele lezi zici futhi bakhethe izinto ze-ceramic kanye nezingubo zokuzivikela ezingamelana nezinselele ezinjalo. Ukuhlolwa kwemvelo kanye nesitifiketi kuqinisekisa ukwethembeka kwebhodi ngaphansi kwezimo zomhlaba wangempela.

Ngokufigqiwe

Ukuklama amabhodi wesifunda se-ceramic wezinhlelo zokusebenza zokushisa okuphezulu kudinga ukunakwa ngokucophelela ekukhethweni kwezinto ezibonakalayo, ukuphathwa kwe-thermal, ukubekwa kwengxenye, iminonjana eqhubayo, amasu okushisa, kanye nezici zemvelo.Ngokucabangela lezi zici nokusebenzisa izinqubo ezihamba phambili, onjiniyela nabaklami bangakha amabhodi ahlinzeka ngokusebenza okuphakeme, ukwethembeka, nokuphila isikhathi eside ezindaweni zokushisa ezeqisayo. Ngakho-ke noma wakha amasistimu kagesi we-aerospace, ezezimoto, noma yimuphi omunye umkhakha odinga ukumelana nezinga lokushisa eliphezulu, ukutshala isikhathi nomzamo ekuklameni amabhodi esekethe e-ceramic ngokungangabazeki kuzoveza imiphumela ethelayo.
