Kupanga kwa mawonedwe ang'onoang'ono a LED kumaphatikizapo njira zamakono
1.Packaging Technology
Mawonekedwe ang'onoang'ono a LEDndi kachulukidwe pansipaP2nthawi zambiri amagwiritsa ntchito nyali 0606, 1010, 1515, 2020, 3528, ndipo mawonekedwe a zikhomo za LED ndi phukusi la J kapena L.Ngati zikhomo ndi welded m'mbali, padzakhala zonyezimira m'dera kuwotcherera, ndipo inki zotsatira za mtundu adzakhala osauka.M'pofunika kuwonjezera chigoba kusintha kusiyana.Ngati kachulukidwe kachulukidwe kachulukidwe, phukusi la L kapena J silingakwaniritse zofunikira, ndipo phukusi la QFN liyenera kugwiritsidwa ntchito.Makhalidwe a njirayi ndikuti palibe zikhomo zowotcherera pambali, ndipo malo otsekemera ndi osawonetsa, zomwe zimapangitsa kuti mtundu ukhale wabwino kwambiri.Kuphatikiza apo, mawonekedwe amtundu wakuda wakuda amawumbidwa ndikuwumbidwa, ndipo kusiyana kwa chinsalu kumawonjezeka ndi 50%, ndipo mawonekedwe azithunzi zowonetserako ndiabwino kuposa zomwe zidawonetsedwa kale.
2.Tekinoloje yokwera:
Kutsika pang'ono kwa malo a chipangizo chilichonse cha RGB pakuwonetsa kwapang'onopang'ono kumapangitsa kuti pakhale mawonekedwe osagwirizana pazenera, zomwe zimafunikira kuti zida zoikira zikhale zolondola kwambiri.
3. Njira yowotcherera:
Ngati kutentha kwa reflow soldering kumakwera mofulumira kwambiri, kumayambitsa kunyowetsa mopanda malire, zomwe zidzachititsa kuti chipangizocho chizisuntha panthawi ya kunyowetsa mopanda malire.Kuyenda kwamphepo kwambiri kungayambitsenso kusuntha kwa chipangizocho.Yesani kusankha reflow soldering makina ndi madera oposa 12 kutentha, liwiro unyolo, kutentha kukwera, kuzungulira mphepo, etc. monga zinthu kulamulira okhwima, ndiko kuti, kukwaniritsa zofunika kuwotcherera kudalirika, komanso kuchepetsa kapena kupewa kusamuka kwa zigawo, ndipo yesetsani kuzilamulira molingana ndi zofuna.Nthawi zambiri, 2% ya pixel pitch imagwiritsidwa ntchito ngati mtengo wowongolera.
4. Ndondomeko ya bolodi yosindikizidwa:
Ndi kachitidwe kachitukuko ka mawonedwe ang'onoang'ono, ma board 4-wosanjikiza ndi 6-wosanjikiza board amagwiritsidwa ntchito, ndipo bolodi losindikizidwa lidzatengera mapangidwe a ma vias abwino ndi mabowo okwiriridwa.The makina pobowola luso sangathenso kukwaniritsa zofunika, ndipo mofulumira anayamba luso laser pobowola adzakumana ndi yaying'ono dzenje processing.
5. Ukadaulo wosindikiza:
Mapangidwe olondola a PCB pad amayenera kulumikizidwa ndi wopanga ndikukhazikitsidwa pamapangidwewo.Kaya kukula kotsegulira kwa stencil ndi magawo osindikizira olondola amagwirizana mwachindunji ndi kuchuluka kwa phala la solder losindikizidwa.Nthawi zambiri, zida za 2020RGB zimagwiritsa ntchito ma stencil opukutidwa a electro-opukutidwa ndi makulidwe a 0.1-0.12mm, ndipo ma stencil a makulidwe a 1.0-0.8 amalimbikitsidwa pazida zosachepera 1010RGB.Makulidwe ndi kukula kwa kutsegula kumawonjezeka molingana ndi kuchuluka kwa malata.Makhalidwe a micro-pitch LED soldering amagwirizana kwambiri ndi kusindikiza kwa solder phala.Kugwiritsa ntchito makina osindikizira ogwira ntchito ndi kuzindikira makulidwe ndi kusanthula kwa SPC kudzatenga gawo lofunikira pakudalirika.
6. Kusintha kwa skrini:
Bokosi lophatikizidwa liyenera kusonkhanitsidwa pazenera lisanawonetse zithunzi ndi makanema oyeretsedwa.Komabe, kulolerana kwapang'onopang'ono kwa bokosi lokha komanso kulolerana kowonjezereka kwa msonkhano sikunganyalanyazidwe chifukwa cha kusonkhana kwa chiwonetsero cha micro-pitch.Ngati kukwera kwa pixel kwa chipangizo chapafupi pakati pa nduna ndi nduna ndi yayikulu kwambiri kapena yaying'ono kwambiri, mizere yakuda ndi mizere yowala idzawonetsedwa.Vuto la mizere yakuda ndi mizere yowala ndi vuto lomwe silinganyalanyazidwe ndipo liyenera kuthetsedwa mwachangu pazithunzi zowonetsera zazing'ono mongaP1.25.Makampani ena amapanga zosintha pomamatira tepi ya 3m ndikusintha bwino mtedza wa bokosilo kuti akwaniritse bwino.
7. Kusonkhanitsa bokosi:
Cabinet imapangidwa ndi ma module osiyanasiyana ophatikizidwa palimodzi.Kusalala kwa nduna ndi kusiyana pakati pa ma modules kumagwirizana mwachindunji ndi zotsatira za nduna pambuyo pa msonkhano.Aluminiyamu mbale processing bokosi ndi kuponyedwa zitsulo zotayidwa bokosi ndi anthu ambiri mabokosi mitundu panopa.Kupalasa kumatha kufika mkati mwa mawaya 10.Kusiyana kwapakati pakati pa ma modules kumawunikidwa ndi mtunda pakati pa ma pixel apafupi a ma module awiriwo.mizere, ma pixel awiri patali kwambiri adzabweretsa mizere yakuda.Musanasonkhanitse, ndikofunikira kuyeza ndikuwerengera gawo la gawoli, kenako sankhani pepala lachitsulo la makulidwe achibale monga cholumikizira chomwe chiyenera kuyikidwiratu pasadakhale.
