Iinkcukacha zenqaku

Njengokuphuhliswa kweshishini lombane we-LED, iimfuno zeshishini ziya ngokungqongqo ngakumbi. Izixhobo zokunyusa umphezulu (ii-SMDs) zihlala zizinto ezinobuchule bokufuma, kwaye ukufuma komoya kungena kwizinto zokupakisha ngokusasazeka. Xa into ye-SMD iqhutywa kwibhodi yesekethe, inkqubo kukuyigqitha kwi-welding yokuphindaphinda enobushushu obuyi-150℃-260℃, Nakwiqondo lobushushu obuphezulu.

, Ukwandiswa ngokukhawuleza kokufuma okungena kuyo kuvelisa umonakalo obaneleyo woxinzelelo lomphunga okanye utshabalalise into ye-LED, ikhokelela ekungaphumeleni kokuthembeka kweengxaki ezinje ngokuqhekeka kwerabha yangaphakathi, i-delamination okanye umonakalo wocingo lwegolide. Ukunqanda ukungaphumeleli kokuthembeka okubangelwa kukufuma, ukugcinwa kunye namanyathelo okuqinisekisa ukufuma ngaphambi kokuba kufakwe iimveliso ze-LED kufuneka zenziwe kakuhle.
Kwixesha elidlulileyo, amakhadi okufuma ayehlala esetyenziselwa ukuvavanya imeko yawo yokufuma, hayi nje enzima, kodwa nokufuma okuvavanywayo akuchanekanga. Ngoku icebise ibhokisi yokuqinisekisa ukufuma okanye ibhokisi yokomisa ukuhlangabezana neemfuno zokwenziwa nokukoma. Isibiyeli sesilivere, i-chip, I-epitaxial chip njalo njalo kufuneka igcinwe kwikhabhinethi ye-nitrogen ukuthintela i-oxidation.
I-Ibhokisi yokungafumiInokugcina izinto kwibhokisi evaliweyo neyomileyo ukwenza indawo yokungafumi kunye ne-anti-oxidation ukunqanda ukufuma ukufunxa, Ukufuma kwe-hydrolysis kunye ne-oxidation. Ibhokisi yokuqinisekisa ukufuma ifunxa iimolekyuli zamanzi ngokusebenzisa i-molekyuli yeemolekyuli enziwe ngezinto ezisebenza kakuhle ze-hygroscopic polymer., kwaye usebenzisa inkqubo "ye-mepe ally alloy" yenkqubo yokuphelisa ukulawula iingcango zangaphakathi nezangaphandle zokufuma kunye ne-dehum. ukujikeleza. Okokugqibela, iimolekyuli zamanzi kwibhokisi yokungafumi kuya kukhutshwa ngaphandle kwekhabhinethi. Kwinkqubo yonke, iimolekyuli zamanzi ziya kuhlala zingesi kwaye aziyi kuvelisa inkqubo yokufunxa ubushushu.
