Ukuyila iibhodi zeesekethe ze-ceramic kwizicelo eziphezulu zokushisa

Kule posi yebhlog, siza kuxoxa ngengqwalasela esisiseko ekufuneka iinjineli kunye nabaqulunqi bazigcine engqondweni ukuze baqinisekise uyilo oluyimpumelelo kunye nokusebenza kweebhodi zeesekethe zeceramic.

Kwiminyaka yakutshanje, iibhodi zeesekethe ze-ceramic ziye zatsala ingqalelo ngenxa yokumelana nobushushu kunye nokuthembeka. Ekwaziwa njengeebhodi zesekethe eziprintiweyo (i-PCBs), ezi bhodi ziyilelwe ngokukodwa ukumelana namaqondo obushushu agqithisileyo afunyanwa kwizicelo zobushushu obuphezulu. Ukusuka kwi-aerospace kunye nemizi-mveliso yeemoto ukuya kumandla ombane kunye nokukhanya kwe-LED, iibhodi zeesekethe ze-ceramic zibonakalise ukuba zitshintsha umdlalo.Nangona kunjalo, ukuyila iibhodi zeesekethe ze-ceramic kwizicelo zokushisa okuphezulu kufuna ukuqwalaselwa ngokucophelela kwizinto ezininzi.

1. Ukukhetha izinto eziphathekayo: Ukukhetha imathiriyeli ye-ceramic efanelekileyo kubalulekile ekuyileni iibhodi zesekethe ezinobushushu obuphezulu.Izinto zeCeramic ezifana ne-aluminium oxide (Al2O3), i-aluminium nitride (i-AlN), kunye ne-silicon carbide (i-SiC) ibonisa ukuhamba kakuhle kwe-thermal kunye nokufakelwa kombane. Kananjalo banokwandiswa kwe-thermal ephantsi, ethintela iibhodi zeesekethe ukuba ziqhekeke okanye ziphazamise ngenxa yokutshintsha kobushushu obugqithisileyo. Ngokukhetha izinto ezifanelekileyo ze-ceramic, abaqulunqi banokuqinisekisa ukuthembeka kunye nokuphila ixesha elide kwiibhodi zabo zeesekethe kwiindawo eziphezulu zokushisa.

2. Ulawulo lwe-Thermal: Ukushisa okuphezulu kunokuchaphazela kakubi ukusebenza kwamacandelo e-elektroniki.Ukunciphisa umngcipheko wokushisa, iindlela ezifanelekileyo zokulawula ukushisa kufuneka zifakwe kwi-design yeebhodi zeesekethe ze-ceramic. Oku kuquka ukusebenzisa iisinki zobushushu, iivent, kunye neepads zokupholisa ukuphelisa ubushushu ngokufanelekileyo. Ukulinganisa kwe-Thermal kunye nokuvavanya kunokunceda ukuchonga iindawo ezinokuthi zibe shushu kunye nokwandisa ukusebenza kokushisa kwebhodi.

3. Ukubekwa kwecandelo: Ukubekwa kwamacandelo kwibhodi yesekethe ye-ceramic kuya kuchaphazela kakhulu ukumelana nokushisa kwayo.Amalungu anamandla aphezulu kufuneka abekwe ngobuchule ukunciphisa ukuxinwa kobushushu kunye nokuqinisekisa ngokulinganayo ukusasazeka kwibhodi yonke. Isithuba phakathi kwamacandelo kufuneka kwakhona siqwalaselwe ngononophelo ukwenzela ukutshatyalaliswa kobushushu obungcono.

4. Umkhondo wokuqhuba kunye noyilo: Iibhodi zeesekethe zeCeramic zifuna amandla aphezulu okuthwala ngoku kuneePCB zemveli.Kubalulekile ukuqinisekisa ukuba iitrayiti zokuqhuba kunye ne-vias ziyilelwe ukujongana nemisinga ephezulu ngaphandle kokutshisa okanye ukubangela ukuhla kwamandla ombane. Umkhondo ububanzi kunye nobukhulu kufuneka bumiselwe ngononophelo ukunciphisa ukuxhathisa kunye nokwandisa ukuchithwa kobushushu.

5. I-teknoloji ye-Welding: Amalungu e-Solder kufuneka axhathise ukushisa okuphezulu kunye nokugcina ingqibelelo yabo, ngakumbi kwizicelo eziphezulu zokushisa.Ukukhetha imathiriyeli echanekileyo yokunyibilika kweqondo eliphezulu kunye nokusetyenziswa kobuchule obufanelekileyo bokudambisa (okufana nokuqukuqela kwakhona okanye ukubethelwa kwamaza) kubalulekile ekuqinisekiseni uqhagamshelo oluthembekileyo nokunciphisa uxinzelelo lobushushu.

6. Iingqwalasela zokusingqongileyo: Ubushushu obuphezulu bezicelo buhlala bukhatshwa ziimeko ezirhabaxa zokusingqongileyo, ezifana nokufuma, ukufuma, imichiza, okanye ukungcangcazela.Abaqulunqi kufuneka baqwalasele le miba kwaye bakhethe izinto ze-ceramic kunye neengubo zokukhusela ezinokumelana nemingeni enjalo. Uvavanyo lokusingqongileyo kunye nokuqinisekiswa kuqinisekisa ukuthembeka kwebhodi phantsi kweemeko zehlabathi langempela.

Isishwankathelo

Ukuyila iibhodi zeesekethe ze-ceramic kwizicelo eziphezulu zokushisa kufuna ingqalelo ekhethekileyo ekukhethweni kwezinto eziphathekayo, ulawulo lwe-thermal, ukubekwa kwecandelo, i-conductive traces, ubuchule be-soldering, kunye nezinto zokusingqongileyo.Ngokuqwalasela le miba kunye nokusebenzisa ezona ndlela zilungileyo, iinjineli kunye nabaqulunqi banokudala iibhodi ezibonelela ngokusebenza okuphezulu, ukuthembeka, kunye nokuphila ixesha elide kwiindawo zobushushu obugqithisileyo. Ke nokuba uphuhlisa iisistim ze-elektroniki ze-aerospace, izithuthi, okanye naliphi na elinye ishishini elifuna ukumelana nobushushu obuphezulu, ukutyala ixesha kunye nomzamo wokuyila ngokufanelekileyo iibhodi zeesekethe zeceramic ngokuqinisekileyo ziya kuvelisa iziphumo ezineziqhamo.
