Ukupholisa koQhagamshelwano loQhagamshelwano: "Indlela yokuzola" ye-High-Power Laser Diode Bar Applications

Njengoko iteknoloji yelaser ephezulu yamandla iqhubeka iqhubela phambili ngokukhawuleza, iiBar Diode zeLaser (i-LDBs) ziye zasetyenziswa ngokubanzi kwi-industrial processing, utyando lwezonyango, i-LiDAR, kunye nophando lwezenzululwazi ngenxa yobuninzi babo bamandla kunye nokukhutshwa kokukhanya okuphezulu. Nangona kunjalo, ngokunyuka kokuhlanganiswa kunye nokusebenza kwangoku kwee-chips ze-laser, imingeni yokulawula i-thermal iya iba yinto ephawulekayo-ichaphazela ngokuthe ngqo ukuzinza komsebenzi kunye nobomi belaser.

Phakathi kwezicwangciso ezahlukeneyo zolawulo lwe-thermal, Ukupholisa koQhagamshelwano kuQhagamshelana kugqame njengenye yezona ndlela zibalulekileyo kunye nezamkelwe ngokubanzi kwi-laser diode bar packaging, ngenxa yesakhiwo sayo esilula kunye ne-thermal conductivity ephezulu. Eli nqaku liphonononga imigaqo, iingqwalasela eziphambili zoyilo, ukhetho lwezinto eziphathekayo, kunye neendlela ezizayo zale "ndlela yokuzola" yokulawula ukushisa.

1. Imigaqo yokuQhubela uQhagamshelwano lokuPholisa

Njengoko igama libonisa, ukupholisa koqhagamshelwano olusebenzayo ngokuseka uqhagamshelwano oluthe ngqo phakathi kwe-laser chip kunye ne-heat sink, eyenza ukuhanjiswa kobushushu okusebenzayo ngokusebenzisa izinto eziphezulu ze-thermal conductivity kunye nokuchithwa ngokukhawuleza kwimeko yangaphandle.

①The HyityaPath:

Kwibar ye-laser diode eqhelekileyo, indlela yobushushu ihamba ngolu hlobo lulandelayo:
Itshiphu → Umaleko weSolder → Inyusela (umzekelo, ikopolo okanye iseramikhi) → TEC (IsiPholisi seThermoelectric) okanye iSinki yoBubushushu → Imekobume engqongileyo

②Iimbonakalo:

Le ndlela yokupholisa iquka:

Ukuhamba kobushushu obugxininisiweyo kunye nendlela emfutshane ye-thermal, ukunciphisa ngokufanelekileyo ubushushu be-junction; Uyilo oluqinileyo, olulungele ukupakishwa kweminiaturized; I-passive conduction, efuna akukho zilophu zokupholisa ezintsonkothileyo.

2. Iingqwalasela eziPhambili zoYilo lokuSebenza kweThermal

Ukuqinisekisa ukupholisa koqhagamshelwano olusebenzayo, le miba ilandelayo kufuneka iqwalaselwe ngononophelo ngexesha loyilo lwesixhobo:

① Ukumelana neThermal kwi-Solder Interface

I-conductivity ye-thermal ye-solder layer idlala indima ebalulekileyo ekuxhathiseni kwe-thermal jikelele. Isinyithi esine-high-conductivity efana ne-AuSn alloy okanye i-indium ecocekileyo kufuneka isetyenziswe, kwaye ubukhulu be-solder layer kunye nokufana kufuneka kulawulwe ukunciphisa imiqobo ye-thermal.

② UKhetho lweMathiriyeli esezantsi

Izinto eziqhelekileyo ezisezantsi ziquka:

I-Copper (Cu): I-conductivity ephezulu ye-thermal, indleko-esebenzayo;

I-Tungsten Copper (WCu) / i-Molybdenum Copper (i-MoCu): I-CTE engcono ihambelana ne-chips, inika zombini amandla kunye ne-conductivity;

I-Aluminium Nitride (i-AlN): I-insulation yombane egqwesileyo, ifanelekile kwizicelo eziphezulu ze-voltage.

③ UMgangatho woQhagamshelwano lomphezulu

Uburhabaxa bomphezulu, ukuba tyaba, kunye nokumanzi kuchaphazela ngokuthe ngqo ukuhanjiswa kobushushu. Ukupholisha kunye nokufakwa kwegolide kuhlala kusetyenziselwa ukuphucula ukusebenza konxibelelwano lwe-thermal.

④ Ukunciphisa iNdlela yeThermal

Uyilo lwesakhiwo kufuneka lujolise ekunciphiseni indlela yokushisa phakathi kwe-chip kunye ne-heat sink. Gwema iileya zemathiriyeli ezingeyomfuneko ukuze uphucule ukusebenza kakuhle kokutshabalalisa ubushushu.

3. Izalathiso zoPhuhliso lwexesha elizayo

Ngomzila oqhubekayo wokuya kwi-miniaturization kunye noxinano lwamandla aphezulu, itekhnoloji yokupholisa i-conduction ye-conduction iyavela kula macala alandelayo:

① Ii-TIM eziDibeneyo zamaleko amaninzi

Ukudibanisa i-metallic thermal conduction kunye ne-flexible buffering ukunciphisa ukuxhathisa ujongano kunye nokuphucula ukuqina kwebhayisekile eshushu.

② ukuPhakhelwa kweSinki yokushisa edibeneyo

Ukuyila i-submounts kunye ne-heat sinks njengesakhiwo esisodwa esidibeneyo ukunciphisa i-interfaces yoqhagamshelwano kunye nokwandisa inkqubo-level yokuhanjiswa kobushushu obusebenzayo.

③ uPhuculo lweSakhiwo seBionic

Ukufaka imiphezulu emincinci elinganisa iindlela zokuphelisa ubushushu bendalo-ezifana "nokuqhuba okufana nomthi" okanye "iipateni ezifana nesikali" -ukuphucula ukusebenza kwe-thermal.

④ Ukulawulwa kobushushu obukrelekrele

Ukubandakanya izinzwa zobushushu kunye nolawulo lwamandla aguquguqukayo kulawulo oluguqukayo lwe-thermal, ukwandisa ubomi bokusebenza kwesixhobo.

4. Isiphelo

Kwimivalo ye-laser diode ephezulu yamandla, ulawulo lwe-thermal alukho nje umngeni wobugcisa-sisiseko esibalulekileyo sokuthembeka. Ukupholisa koqhagamshelwano, kunye neempawu zayo ezisebenzayo, ezivuthiweyo, kunye neendleko ezifanelekileyo, zihlala zisesinye sezisombululo eziphambili zokutshatyalaliswa kobushushu namhlanje.

5. Malunga Nathi

ELumispot, sizisa ubuchwephesha obunzulu bokupakishwa kwe-laser diode, uvavanyo lolawulo lobushushu, kunye nokukhethwa kwezinto.
