Kampani ya Ningbo Deamakndi kampani yokhazikika pakupanga ndi kupanga magetsi anzeru usiku. Tekinoloje ya COB light source imagwiritsidwa ntchito pazinthu zina zakampani.

Gwero la kuwala kwa COB ndi gwero lamphamvu kwambiri lophatikizika pamwamba. Ndi ukadaulo wapamwamba kwambiri wophatikizira pamwamba wowunikira womwe umayika mwachindunji CHIPIRI cha LED pagawo lachitsulo lagalasi lokhala ndi chiwonetsero chambiri. Tekinoloje iyi imachotsa lingaliro la bracket ndipo ilibe electroplating, reflow welding ndi njira ya SMT, kotero njirayo imachepetsedwa pafupifupi gawo limodzi mwa magawo atatu ndipo mtengo umapulumutsidwanso ndi gawo limodzi mwa magawo atatu.

Gwero la kuwala kwa COB litha kupangidwa molingana ndi mawonekedwe amtundu wamalo owunikira komanso kukula kwake.

Zogulitsa: zotsika mtengo, zosavuta

Kukhazikika kwamagetsi, kapangidwe ka dera, kapangidwe ka kuwala, kapangidwe ka kutentha kwa sayansi ndi zololera;

Ukadaulo wozama wa kutentha umatengedwa kuti uwonetsetse kuti LED ili ndi chiwongola dzanja chotsogola chamafuta (95%).

Ndi yabwino kwa yachiwiri kuwala mafananidwe cha mankhwala ndi bwino kuunikira khalidwe.

Chiwonetsero chamtundu wapamwamba, kuwala kofananako, palibe kuwala, thanzi ndi chitetezo cha chilengedwe.

Kuyika kosavuta, kosavuta kugwiritsira ntchito, kuchepetsa zovuta za mapangidwe a nyali, kupulumutsa kukonza nyali ndi ndalama zokonzekera zotsatila.

 

Pali mitundu iwiri ikuluikulu yaukadaulo wa Chip: ukadaulo wa COB ndiukadaulo wa Flip Chip. Chip on board packaging (COB), semiconductor chip handover yolumikizidwa ku PRINTED circuit board, chip ndi gawo lapansi kulumikizana kwamagetsi kumazindikirika ndi njira ya lead suture, ndikukutidwa ndi utomoni kuti zitsimikizire kudalirika.

 

Njira ya Chip On Board (COB) ndikuphimba malo oyikapo silicon wafer ndi thermally conductive epoxy resin (nthawi zambiri siliva doped epoxy resin) Pamwamba pa gawo lapansi, ndiyeno ikani chowotcha cha silicon pamwamba pa gawo lapansi, kutentha kutentha mpaka chowotcha cha silicon chokhazikika Pagawo lapansi. Kenako kuwotcherera waya kumagwiritsidwa ntchito kukhazikitsa kulumikizana mwachindunji pakati pa silicon wafer ndi gawo lapansi.
