GOB vs. COB 3 Mins Jagora Mai Sauri 2024

1. Gabatarwa

Kamar yadda aikace-aikacen nunin nunin LED ke ƙara yaɗuwa, buƙatun ingancin samfur da aikin nuni sun ƙaru. Fasahar SMD ta gargajiya ba za ta iya biyan bukatun wasu aikace-aikace ba. Sabili da haka, wasu masana'antun suna canzawa zuwa sababbin hanyoyin haɓakawa kamar fasahar COB, yayin da wasu suna haɓaka akan fasahar SMD. Fasahar GOB ita ce sake fasalin ingantattun tsarin rufewa na SMD.

Masana'antar nunin LED ta haɓaka hanyoyin ɓoye daban-daban, gami da nunin COB LED. Tun daga farkon fasahar DIP (Direct Insertion Package) zuwa fasahar SMD (Surface-Mount Device), sannan zuwa fitowar COB (Chip on Board) encapsulation, daga karshe kuma zuwan GOB (Glue on Board) encapsulation.

Shin fasahar GOB za ta iya ba da damar aikace-aikace masu faɗi don nunin nunin LED? Waɗanne halaye za mu iya tsammanin ci gaban kasuwa na gaba na GOB? Mu ci gaba.

2. Menene GOB Encapsulation Technology?

2.1GOB LED nuniallon nunin LED ne mai karewa sosai, yana ba da ruwa mai hana ruwa, tabbatar da danshi, mai jurewa tasiri, mai ƙura, juriya, juriya mai haske mai shuɗi, juriya mai gishiri, da ƙarfin juriya. Ba sa haifar da mummunan tasirin zafi ko asarar haske. Gwaje-gwaje masu yawa sun nuna cewa manne da aka yi amfani da shi a cikin GOB har ma yana taimakawa wajen zubar da zafi, rage rashin gazawar LEDs, inganta yanayin nuni, kuma yana kara tsawon rayuwarsa.

2.2 Ta hanyar sarrafa GOB, abubuwan da suka gabata na granular pixel akan fuskar GOB LED ana canza su zuwa ƙasa mai santsi, lebur, samun canji daga tushen haske zuwa tushen haske. Wannan yana sa hasken panel ɗin LED ɗin haske ya zama mafi daidaituwa kuma tasirin nuni ya ƙara bayyana da kuma bayyananne. Yana da mahimmanci haɓaka kusurwar kallo (kusan 180 ° a kwance da a tsaye), yana kawar da tsarin moiré yadda ya kamata, yana inganta bambancin samfurin sosai, yana rage haske da tasiri mai ban mamaki, kuma yana rage gajiyar gani.

3. Menene COB Encapsulation Technology?

COB encapsulation yana nufin haɗa guntu kai tsaye zuwa ma'aunin PCB don haɗin lantarki. An gabatar da shi da farko don magance matsalar rashin zafi na bangon bidiyo na LED. Idan aka kwatanta da DIP da SMD, COB encapsulation yana da halin ceton sararin samaniya, sauƙaƙe ayyukan ɓoyewa, da ingantaccen sarrafa zafi. A halin yanzu, an fi amfani da murfin COB a cikinuni mai kyau na LED.

4. Menene Amfanin COB LED Nuni?

Ultra-baƙi da Haske:Dangane da bukatun abokin ciniki, ana iya amfani da allunan PCB tare da kauri daga 0.4 zuwa 1.2mm, rage nauyi zuwa kusan kashi ɗaya bisa uku na samfuran gargajiya, rage girman tsarin, sufuri, da farashin injiniya ga abokan ciniki.

Tasiri da Juriya:Nunin COB LED yana rufe guntuwar LED kai tsaye a cikin madaidaicin matsayi na hukumar PCB, sannan ya tattara kuma ya warkar da shi tare da manne resin epoxy. Fuskar ma'aunin haske yana fitowa, yana mai da shi santsi da wuya, mai jurewa tasiri, da juriya.

Faɗin Duban kusurwa:COB encapsulation yana amfani da fitowar haske mai zurfi mai zurfi, tare da kusurwar kallo sama da digiri 175, kusa da digiri 180, kuma yana da kyakkyawan tasirin haske mai yaduwa.

Ƙarfin Ƙarfin Zafi:COB LED allon rufe haske a kan PCB jirgin, da kuma jan karfe a kan PCB jirgin da sauri gudanar da zafi na haske core. Kauri mai kauri na tagulla na hukumar PCB yana da ƙayyadaddun buƙatun tsari, haɗe tare da aiwatar da plating na zinari, kusan kawar da tsananin ƙarancin haske. Don haka, akwai ƴan matattun fitilu, suna ƙara tsawon rayuwa.

Sawa-Juriya da Sauƙi don Tsaftacewa:COB LED fuska fuskar haske yana fitowa cikin siffa mai siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar siffar haske da haske, da sauƙi. Idan maƙasudi mara kyau ya bayyana, ana iya gyara shi aya ta aya. Babu abin rufe fuska, kuma ana iya tsabtace ƙura da ruwa ko zane.

Mafi kyawun Yanayin Yanayi:Maganin kariyar sau uku yana ba da ƙwararren mai hana ruwa, tabbatar da danshi, ƙazanta-hujja, ƙurar ƙura, anti-static, oxidation, da juriya na UV. Yana iya aiki akai-akai a yanayin zafi daga -30 ° C zuwa 80 ° C.

5. Menene Bambanci Tsakanin COB da GOB?

Babban bambanci tsakanin COB da GOB yana cikin tsari. Ko da yake COB encapsulation yana da m surface da mafi kyau kariya fiye da na gargajiya SMD encapsulation, GOB encapsulation ƙara wani manne aikace-aikace tsari zuwa ga allo surface, inganta kwanciyar hankali na LED fitilu da kuma ƙwarai rage yiwuwar haske saukad da, sa shi mafi kwanciyar hankali.

6. Wanne Yafi Riba, COB ko GOB?

Babu tabbataccen amsa ga wacce ta fi kyau, nunin COB LED ko nunin GOB LED, saboda ingancin fasahar rufewa ya dogara da dalilai daban-daban. Babban abin la'akari shine ko kun ba da fifikon ingancin fitilun LED ko kariyar da aka bayar. Kowace fasaha na ɓoyewa yana da fa'ida kuma ba za a iya yin hukunci a duniya ba.

Lokacin zabar tsakanin COB da GOB encapsulation, yana da mahimmanci a yi la'akari da yanayin shigarwa da lokacin aiki. Waɗannan abubuwan suna tasiri sarrafa farashi da bambance-bambancen aikin nuni.

7. ƙarshe

Dukansu fasahar encapsulation GOB da COB suna ba da fa'idodi na musamman don nunin LED. GOB encapsulation yana haɓaka karewa da kwanciyar hankali na fitilun LED, yana ba da ingantaccen ruwa, ƙura, da kaddarorin haɓaka, yayin da inganta haɓakar zafi da aikin gani. A gefe guda, COB encapsulation ya yi fice a cikin ceton sararin samaniya, ingantaccen sarrafa zafi, da samar da sauƙi mai sauƙi, mafita mai jurewa. Zaɓin tsakanin COB da GOB encapsulation ya dogara da ƙayyadaddun buƙatu da abubuwan da suka fi dacewa na yanayin shigarwa, kamar dorewa, kula da farashi, da ingancin nuni. Kowace fasaha tana da ƙarfinta, kuma ya kamata a yanke shawara bisa cikakken kimanta waɗannan abubuwan.

Idan har yanzu kuna cikin ruɗani game da kowane fanni,tuntube mu a yau.RTLEDya himmatu wajen samar da mafi kyawun mafita na nunin LED.
