Ntchito Zofunikira za Kuchiritsa kwa UV LED M'munda wa Microelectronics

UV LED  ndi njira imene amagwiritsa ntchito ultraviolet (UV) light-emitting diodes (LEDs) kuchiritsa kapena kuyanika zomatira, zokutira, inki, ndi zipangizo zina. Njirayi imaphatikizapo kuyatsa zinthuzo ku kuwala kwa UV, komwe kumapangitsa kuti zinthuzo zikhale zolimba kapena kuchiritsa. UV LED  Ndi njira yofulumira komanso yothandiza kwambiri kuposa njira zochizira, monga kuchiritsa kapena kuyanika mpweya. Itha kugwiritsidwa ntchito m'mafakitale osiyanasiyana, kuphatikiza zamagetsi, zamagalimoto, ndi zamankhwala.

Kuwala kwa UV kuchokera ku ma LED nthawi zambiri kumakhala 365nm-385nm, kumakhala ndi mphamvu zambiri komanso kumagwirizana kwambiri, izi zimalola kuchiritsa kolondola komanso kosasintha. Zimathandizanso kuti pakhale njira yabwino kwambiri yochizira mumasekondi, poyerekeza ndi mphindi kapena maola a njira zina zochiritsira. UV LED  Komanso sizimapanga kutentha, zomwe zingakhale zopindulitsa pazinthu zina zomwe kutentha kungakhale vuto.

Kuchiritsa kwa UV vs UV Kuchiritsa kwa LED. Kodi Kusiyana Kwakukulu Ndi Chiyani?

Kusamalira UV  nthawi zambiri amagwiritsa ntchito nyali ya UV kapena nyali ya mercury vapor kuchiritsa zida, pomwe UV   Kuwongolera kwa LED  amagwiritsa ntchito ma UV kuwala-emitting diodes (LEDs) kuchiza zipangizo. UV   Kuwongolera kwa LED  amatha kuchiza m'masekondi, pomwe kuchiritsa kwa UV kumatha kutenga mphindi kapena maola kuti kuchire. UV LED  Ndiwopatsa mphamvu kuposa kuchiritsa kwa UV chifukwa imagwiritsa ntchito mphamvu zochepa kupanga kuwala kwa UV.

UV LED  imagwiritsa ntchito kuwala kwapakati pa 365nm-385nm, kulola kuchiritsa kosasintha. Kuchiritsa kwa UV kumagwiritsa ntchito kuwala kochulukirapo komwe kumatha kusiyanasiyana kutengera mtundu wa nyali yomwe imagwiritsidwa ntchito. UV LED  ndi ochezeka kwambiri ndi chilengedwe kuposa kuchiritsa kwa UV chifukwa sikutulutsa mpweya woipa.

Kugwiritsa Ntchito Machiritso a UV LED M'munda wa Microelectronics

Mu gawo la microelectronics, Kuchiritsa kwa UV-LED  Guluu amagwiritsidwa ntchito kwambiri pomangirira ndi kusindikiza zida za microelectronic, monga masensa, tchipisi, ndi ma transistors. Amagwiritsidwanso ntchito popanga zida za ma microelectronics komanso kusonkhana kwa PCB.

Zomatira za UV, zomwe zimadziwikanso kuti zomatira kapena zomatira zochilitsidwa ndi UV, ndi mtundu wa zomatira zomwe zimayatsidwa kapena kuchiritsidwa chifukwa cha kuwala kwa ultraviolet (UV). Zomatirazi zitha kupangidwa kuchokera kumitundu yosiyanasiyana ya ma polima, monga acrylate kapena epoxy. Akakumana ndi kuwala kwa UV, ma monomers omwe ali mu utomoniwa amachitirapo ndi polymerize, kupanga chomangira champhamvu.

Zosindikizira za UV ndizosiyana ndi zosindikizira zachikhalidwe, monga epoxies ndi cyanoacrylates, zomwe zimafuna nthawi kuti zichiritse kutentha kapena kutentha kuti zichiritse. Zomatira za UV ndi zosindikizira, komabe, zimachiritsa pafupifupi nthawi yomweyo zikayatsidwa ndi kuwala kwa UV, zomwe zimawapangitsa kukhala abwino kwambiri polumikizira makina othamanga kwambiri.

Nazi njira zina UV LED  zimachitika kudzera zomatira m'munda wa microelectronics.

Kumanga ndi kusindikiza

UV LED  guluu amagwiritsidwa ntchito kugwirizana ndi kusindikiza microelectronic zigawo zikuluzikulu, kupereka njira yachangu, yothandiza, ndi yolondola yomangira ndi kusindikiza. Kuwala kwa UV kuchokera ku ma LED kumapereka njira yochizira mwachangu yomwe imachotsa kufunikira kwa kutentha ndi kupanikizika, zomwe zingawononge zida zamagetsi zamagetsi. Zotsatira zake, izi zimatipatsa mankhwala omwe ali ndi mwayi wochepa kwambiri wokhala ndi zolakwika.

Encapsulation

Guluu wochiritsa wa UV-LED amagwiritsidwa ntchito kuyika zida za microelectronic kuti ziteteze ku chinyezi, kutentha, ndi zina zachilengedwe. Kuwala kwa UV kuchokera ku ma LED kumapereka njira yochiritsira mwachangu, ndipo chisindikizo chomwe chimapangidwa chimakhala chopanda mpweya, chomwe chimapereka chitetezo chokhalitsa. Mothandizidwa ndi UV LED  sikuti encapsulation idzakhala yapamwamba kwambiri koma idzawonjezera chitetezo cha mankhwala omaliza.

Msonkhano wa PCB

Guluu wochiritsa wa UV-LED amagwiritsidwa ntchito pamisonkhano ya PCB (Printed Circuit Board), komwe amagwiritsidwa ntchito kulumikiza zigawo zosiyanasiyana za PCB palimodzi. Poyerekeza ndi ukadaulo wakale monga zomatira ndi zosindikizira za UV, guluu wakuchiritsa wa UV-LED ndi wachangu, wothandiza, komanso wolondola, ndipo umathandizira kukonza magwiridwe antchito ndi kudalirika kwa PCB. Zonse, UV LED  zosindikizira zimathandizira kupanga matabwa a PCB bwino kuposa zomwe zida zam'mbuyomu ndi omwe akupikisana nawo UV LED  kupereka.

Conductive Adhesive

UV-LED kuchiritsa guluu Angagwiritsidwenso ntchito ngati zomatira conductive, amene amathandiza kuthetsa kufunika soldering, amene akhoza kuwononga zigawo zikuluzikulu za microelectronics. UV LED  guluu limakupatsani m'malo mwa zomatira zachikhalidwe za UV ndi zosindikizira. Ndizosiyana chifukwa apa magawo ang'onoang'ono samafalikira mu mawonekedwe a UV. Kuphatikiza apo, chomwe chimawapangitsa kukhala osankhidwa mwapadera ndi chifukwa cha kumveka kwawo kowoneka bwino.

Zojambula Zokhudza

Opanga zida za touchscreen nthawi zambiri amakonda kugwiritsa ntchito UV LED  zomatira pamaso msonkhano. Gawo lopindulitsa kwambiri ndi kutentha pang'ono komanso kuchiritsa kofunidwa komwe mankhwalawa amapereka kudzera mu nyali za UV LED. Zimathandizira kupewa kuwonongeka kwa zida zamagetsi zomwe zingawonongeke popereka zotsatira zokhazikika komanso zanthawi yomweyo.

Kodi Mumakondanso Kuchiritsa kwa UV LED? Tili Ndi Njira!

UV LED  ndi gawo lomwe likukula lomwe lili ndi kuthekera kwakukulu. Ngati inunso amene wayamba kupeza chidwi m'munda wa UV LED  ndipo mukufuna kudzifufuza nokha, tili ndi zabwino UV LED  zanu; tili ndi kalozera woyenera kwa inu.

Tiahui  ndi m'modzi mwa otsogola Opanga UV LED  yomwe ili ndi zosankha zambiri zomwe mungasankhe. Kaya muli m'makampani azachipatala kapena zaulimi, Tianhui ili ndi chinthu choyenera kwa inu. Kuyambira UV LED diode  Kufikira UV LED , tili ndi chilichonse m'maganizo mwanu. Ngati mukufuna khalidwe ndi mtengo, Tianui ndi dzina la masewera.

Kuzikulunga

UV LED  ukadaulo ndiwosintha kwambiri. Ndi izi, mwayi wambiri watsegulidwa. Poyerekeza ndi matekinoloje azikhalidwe monga kuchiritsa kwa UV, UV LED  imapereka magwiridwe antchito abwino komanso okhazikika komanso okhazikika.

Tikukhulupirira kuti nkhaniyi idakuthandizani kupeza mayankho a mafunso anu okhudzana ndi kugwiritsa ntchito UV LED mu microelectronics. Musaiwale kuyang'ana Tianhui pazinthu zabwino kwambiri za UV LED.
