SFPCOBNon-hermeticallySealed
Txij li thaum lub sijhawm ua haujlwm ntawm cov ntaub ntawv nruab nrab ntawm lub lag luam pib thov kom muaj peev xwm, qhov ntim ntawm qhov kho qhov muag tau pib tshwm rau hauv COB tsis ntim cov ntim quav. Daim ntawv thov ntawm COB thev naus laus zis tseem ua rau cov kho qhov muag kom pom qhov zoo ntawm cov kev siv tshuab nplai hauv kev ntim khoom.
COB (nti rau ntawm board) uas tsis yog hermetically kaw. Nws yog pob ntawv daim npav qhov twg cov nti tau khi ncaj qha rau ntawm PCB. Ntov optoelectronic nti ncaj qha mus rau hauv lub rooj tsav xwm hauv Circuit Court nrog kev them nyiaj muaj tus nqi epoxy cob, thiab cov hluav taws xob txuas nrog los ntawm kev siv xov hlau. Thaum kawg, epoxy nti lossis styrene resin (Silicone) nqus dej nrog kua.
Qhov txiaj ntsig ntawm qhov txheej txheem tsis ntim cov hermetically yog kev siv lub tshuab ua haujlwm. Daim ntawv thov ntawm COB thev naus laus zis hauv qhov chaw sib txuas lus kho qhov muag kuj tseem ua rau optical module kom paub qhov zoo ntawm cov tshuab nplai tsim hauv kev ntim khoom.
Tam sim no, COB thev naus laus zis tau siv dav hauv cov khoom sib txuas lus luv luv khoom siv VCSEL modules. Kev sib xyaw ua ke siab silicon cov khoom lag luam kuj tau ntim nrog COB thev naus laus zis.
