Menene Ma'anar Kunshin COB? Menene Banbancin Kundin Gargajiya

Mene ne COB ke kunshe da Cache akan Jirgin ) An saita Bangbang akan allon buga. Kamar yadda masu samar da IC ke rage QFP (hanyar rufewa na sassan SMT) marufi a cikin sarrafa LCD da kuma samar da kwakwalwan kwamfuta masu alaƙa. Sabili da haka, hanyar SMT na gargajiya a cikin samfurori na gaba an maye gurbinsu a hankali. Bambanci tsakanin fasahar fakitin COB da marufi na gargajiya? Marufi na COB shine kunshin da ke ɗaure guntun LED kai tsaye akan allon PCB. Menene bambance-bambance tsakanin wannan hanyar marufi da LED SMD na gargajiya da sauran fasahohin marufi, kuma wanne ya fi kyau? Kwatanta waɗannan hanyoyin marufi guda biyu? Akwai manyan nau'ikan fasahar guntu tsirara guda biyu: ɗayan fasahar COB, ɗayan kuma fasahar FLIP Chip (FLIP Chip). Fasahar marufi na LED COB Abin da ake kira COB shine a riƙa guntu tsirara tare da mannewa mai ɗawainiya ko mara amfani akan abin da ke haɗa haɗin gwiwa, sannan aiwatar da maɓallin gubar don cimma haɗin wutar lantarki.

Bayan an wuce gwajin, ana rufe mannen guduro. Idan aka kwatanta da fasahar marufi na gargajiya, fasahar COB tana da fa'idodi masu zuwa: ƙarancin farashi; ajiyar sararin samaniya; balagagge sana'a. Fasahar fakitin LED COB ita ma ba ta isa ba, wato, injin walda daban da na'urar tattara kaya ana buƙatar. Wani lokaci gudun ba zai iya ci gaba da PCB faci stringent bukatun ga muhalli; ba za a iya kiyaye shi ba. COB, wannan fasahar marufi na gargajiya za ta taka muhimmiyar rawa a cikin marufi na samfuran šaukuwa. Matsalolin gama gari na fasahar marufi na LED COB Q: LED hasken marufi COB tsarin marufi na tsakiyar-launi. Lokacin da aka yi amfani da marufi na COB a cikin marufi na COB, yana amfani da tsarin marufi mai ƙarfi na gargajiya. Bayan yin burodi, an gano cewa yawan zafin jiki yana da girma sosai. , 5000K a matakin farko, amma manne foda shine 10000K bayan gasasshen gasa. Shin matsalar tsarin yin burodi na silicone ko manne foda bai dace ba. Don Allah kowa! A: Yanayin yin burodi ya yi yawa, kuma nisan lantarki ya zama kusa. Rage lokacin feshin zuwa lokacin yin burodi. Ya kamata a haifar da bambancin zafin jiki ta hanyar foda mai kyalli. Da sauri taurin don guje wa foda mai kyalli! Yi nazarin yanayin dumama akwatin tanda Q: Menene bambanci tsakanin fasahar marufi na LAMP LED da marufi na COB a cikin fasahar marufi na LED? Dukansu ana saka su kai tsaye maimakon faci. Menene bambanci? Menene bangarorin? Shin wanda ya dace da babban iko, ɗaya don ƙaramin iko? A: Fasahar COB gabaɗaya ta fi dacewa da madaidaicin ma'auni ɗaya tare da sauran abubuwan lantarki. Idan LED COB an yi shi a cikin kunshin encapsulation kai tsaye, ya kamata ya zama module tare da wasu ayyuka na musamman kamar aikin walƙiya ko halayen dijital, ƙirar sarrafa launi, da sauransu. Duka babba da ƙarami na iya zama COB ko LAMP. Babu wani bambanci a wannan bangaren. Tambaya: Zan iya tambayar haɗaɗɗen marufi na COB azaman tushen hasken jirgin sama, shin zai maye gurbin samfuran facin na yanzu? A: Babu maye gurbin, duka biyu suna cikin ci gaban gaba, kuma duka biyu za su kasance tare na dogon lokaci.
