Ob Hom LED Pob

Lub LED (lub teeb emitting diode) ua cov khoom tseem ceeb rau LED zaub, feem ntau yog ob hom pob, xws li DIP (Direct Insert Package, lossis Dual Inline Package) thiab SMD (Nto Mounted Devices). Feem ntau hais lus, DIP LED tsuas yog siv rau sab nraum zoov LED zaub screen, thaum SMD LED yog siv rau sab hauv LED npo. Tsis tas li ntawd, qhov txawv ntawm lawv muaj dab tsi?

DIP LED siv potting daim ntawv rau ntim. Cov txheej txheem potting yog, txhaj cov kua epoxy resin nyob rau hauv LED molding kab noj hniav thaum xub thawj, thiab ces ntxig rau lub siab LED brackets, vuam qhov chaw, muab tso rau hauv lub qhov cub rau epoxy resin tom qab kho, thiaj li yuav ua rau lub LED molded los ntawm pwm kab noj hniav. Vim cov txheej txheem fabrication yooj yim, tus nqi qis, nws muaj kev lag luam ntau dua. Nyob rau hauv loj ntim, nws yuav siv tau rau dag tso dag los yog tsis siv neeg tshuab ua hauj lwm. Txij li thaum nws lub siab ci, yooj yim rau kev ua dej tsis zoo, yog li nws yog siv los ua lub teeb pom kev zoo rau sab nraum zoov LED zaub screen.

SMD LED tseem hu ua SMT (nto mounted thev naus laus zis), dhau los ntawm SMT thev naus laus zis encapsulating diode, txuas cov teeb rau saum npoo ntawm PCB board, es tsis txhob ntsaws lub teeb taw los ntawm PCB pawg thawj coj saib. Nws yog qhov tsim nyog rau kev ua haujlwm SMT, uas tuaj yeem rov ua dua, thiab yog li daws cov teeb meem xws li ci ntsa iab, lub kaum sab xis ntawm qhov pom, flatness, sib xws, thiab kev ntseeg tau. Lub sib zog PCB phaj thiab ib qho kev cuam tshuam cov khoom siv, kev txhim kho ntawm kev tshem tawm hnyav dua carbon steel pin ntawm DIP LED. Cov zaub epoxy resin yog tsawg dua txheej txheej los sau, txo qhov loj thiab txo qhov hnyav. Yog li, nto mount LED tau yooj yim integrate cov khoom hnyav los ntawm ib nrab, nws thiaj li ua rau daim ntawv thov zoo meej.

SMT LED qhov chaw yog siv rau sab hauv tsev LED npo. Txawm li cas los xij, nrog cov txheej txheem thev naus laus zis, qhov ci ci ntawm SMD LED tau txhim kho zoo heev, kev ua dej tsis zoo kuj tuaj yeem daws tau zoo, yog li ntawd, SMD LED tau siv ntau dua rau sab nraum zoov LED zaub screen.
