SMD & COB & GOB LED Ndani adzakhala ukadaulo wotsogozedwa ndi mayendedwe?
Chiyambireni chitukuko cha Makampani Owonetsera a LED, njira zosiyanasiyana zopangira ndi kuyika zaukadaulo wapang'onopang'ono wapang'onopang'ono zawonekera.
Kuchokera paukadaulo wam'mbuyomu wa DIP kupita kuukadaulo wapackage wa SMD, mpaka pakuwonekera kwaukadaulo wamapaketi a COB, ndipo pamapeto pake mpaka kutuluka kwateknoloji ya GOB.
SMD Packaging Technology
Ukadaulo wowonetsa wa SMD LED
SMD ndiye chidule cha Surface Mounted Devices.Zogulitsa za LED zophatikizidwa ndi SMD (ukadaulo wokwera pamwamba) zimayika makapu a nyale, mabatani, zowotcha, zowongolera, utomoni wa epoxy, ndi zida zina kukhala mikanda yanyali yamitundu yosiyanasiyana.Gwiritsani ntchito makina oyika othamanga kwambiri kuti mugulitse mikanda ya nyali pa bolodi yozungulira yokhala ndi kutentha kwapang'onopang'ono kuti mupange mayunitsi owonetsera okhala ndi mabala osiyanasiyana.
SMD LED luso
Malo ang'onoang'ono a SMD nthawi zambiri amawonetsa mikanda ya nyali ya LED kapena amagwiritsa ntchito chigoba.Chifukwa chaukadaulo wokhwima komanso wokhazikika, mtengo wotsika wopanga, kutulutsa kwabwino kwa kutentha, komanso kukonza bwino, imakhalanso ndi gawo lalikulu pamsika wamagetsi a LED.
Chiwonetsero chachikulu cha SMD LED chomwe chimagwiritsidwa ntchito popanga zikwangwani zakunja zowonetsera za LED.
COB Packaging Technology
Chiwonetsero cha LED cha COB
Dzina lonse la teknoloji yopangira COB ndi Chips on Board, yomwe ndi teknoloji yothetsera vuto la kutentha kwa LED.Poyerekeza ndi in-line ndi SMD, imadziwika ndi kupulumutsa malo, kufewetsa kaphatikizidwe kazinthu, komanso kukhala ndi njira zowongolera kutentha.
Ukadaulo wa COB LED
Chip chopanda kanthu chimamamatira ku gawo lapansi lolumikizana ndi guluu conductive kapena non-conductive, ndiyeno kulumikizana kwa waya kumachitika kuti azindikire kulumikizana kwake kwamagetsi.Ngati chip chopanda kanthu chikuwonekera mwachindunji mlengalenga, chikhoza kuipitsidwa kapena kuwonongeka kopangidwa ndi anthu, komwe kumakhudza kapena kuwononga ntchito ya chip, kotero kuti chip ndi mawaya omangirira amatsekedwa ndi guluu.Anthu amachitchanso mtundu uwu wa encapsulation kukhala encapsulation yofewa.Ili ndi maubwino ena pakupanga bwino, kukana kutsika kwamafuta, mtundu wa kuwala, kugwiritsa ntchito, komanso mtengo wake.
SMD-VS-COB-LED-Display
Chiwonetsero chachikulu cha COB LED chomwe chimagwiritsidwa ntchito m'nyumba komanso pang'ono pang'ono yokhala ndi chiwonetsero champhamvu cha LED Screen Display.
GOB Technology process
Chiwonetsero cha LED cha GOB
Monga tonse tikudziwira, matekinoloje atatu akuluakulu a DIP, SMD, ndi COB mpaka pano akugwirizana ndi teknoloji ya LED chip-level, ndipo GOB sichimakhudza chitetezo cha tchipisi ta LED, koma pa gawo lowonetsera la SMD, chipangizo cha SMD. Ndi mtundu waukadaulo woteteza kuti phazi la PIN la bulaketi limadzazidwa ndi guluu.
GOB ndiye chidule cha Glue pa board.Ndi teknoloji yothetsera vuto la chitetezo cha nyali za LED.Imagwiritsa ntchito zida zatsopano zowonekera kuti zikhazikitse gawo lapansi ndi gawo lake lakuyika la LED kuti lipange chitetezo chokwanira.Zakuthupi sizimangowoneka bwino kwambiri komanso zimakhala ndi matenthedwe apamwamba kwambiri.Gome laling'ono la GOB likhoza kusinthasintha ku malo aliwonse ovuta, kuzindikira makhalidwe enieni a chinyezi, madzi, fumbi, kumenyana, ndi anti-UV.
Poyerekeza ndi Chiwonetsero chachikhalidwe cha SMD LED, mawonekedwe ake ndi chitetezo chokwera, sungani chinyezi, chosalowa madzi, odana ndi kugunda, odana ndi UV, ndipo angagwiritsidwe ntchito m'malo ovuta kwambiri kupewa magetsi akufa m'dera lalikulu ndi kuyatsa.
Poyerekeza ndi COB, mawonekedwe ake ndi kukonza kosavuta, kutsika mtengo wokonza, ngodya yayikulu yowonera, ngodya yoyang'ana yopingasa, ndi mawonekedwe owoneka bwino amatha kufikira madigiri 180, zomwe zimatha kuthana ndi vuto la COB kulephera kusakaniza magetsi, kusinthasintha kwakukulu, kulekanitsa mitundu, kusayenda bwino pamwamba, etc. vuto.
GOB yaikulu yomwe imagwiritsidwa ntchito pa Indoor LED Poster Display Digital Advertising Screen.
Masitepe opangira zinthu zatsopano za GOB agawidwa pafupifupi masitepe atatu:
1. Sankhani zida zabwino kwambiri, mikanda ya nyali, ma ultra-high brush IC solutions, ndi tchipisi tapamwamba ta LED.
2. Pambuyo posonkhanitsa mankhwalawa, amakalamba kwa maola 72 pamaso pa GOB potting, ndipo nyali imayesedwa.
3. Pambuyo pa GOB potting, kukalamba kwa maola ena a 24 kuti mutsimikizirenso khalidwe la mankhwala.
Pampikisano waukadaulo wapang'ono wapang'onopang'ono wa LED, kuyika kwa SMD, ukadaulo wa COB, ndiukadaulo wa GOB.Ponena za omwe atatuwa angapambane mpikisano, zimatengera luso lamakono komanso kuvomereza msika.Wopambana womaliza ndani, tiyeni tidikire ndikuwona.
