Laser ya UV ndi mtundu wa laser yomwe ili ndi kutalika kwa 355nm. Chifukwa cha kutalika kwake kochepa komanso m'lifupi mwake, laser ya UV imatha kupanga malo ochepa kwambiri ofunikira ndikusunga malo ang'onoang'ono kwambiri omwe amakhudza kutentha. Chifukwa chake, imatchedwanso "processing yozizira". Zinthu izi zimapangitsa laser ya UV kuti igwire ntchito molondola kwambiri popewa kusintha kwa zinthuzo.
Masiku ano, popeza ntchito zamafakitale zimafuna kwambiri kuti laser igwire bwino ntchito, anthu ambiri akusankha laser ya 10W+ nanosecond UV. Chifukwa chake, kwa opanga laser ya UV, kupanga laser yamphamvu kwambiri, yopapatiza, komanso yobwerezabwereza pafupipafupi yapakati-yapamwamba ya nanosecond UV kudzakhala cholinga chachikulu chopikisana pamsika.
Laser ya UV imagwira ntchito powononga mwachindunji ma bond a mankhwala omwe amalumikiza zigawo za atomu ya chinthucho. Njirayi siitentha malo ozungulira, kotero ndi njira "yozizira". Kuphatikiza apo, zinthu zambiri zimatha kuyamwa kuwala kwa ultraviolet, kotero laser ya UV imatha kukonza zinthu zomwe magwero ena a infrared kapena laser ena owoneka sangathe kukonza. Laser ya UV yamphamvu kwambiri imagwiritsidwa ntchito makamaka m'misika yapamwamba yomwe imafuna kukonza kolondola kwambiri, kuphatikiza kuboola/kudula kwa FPCB ndi PCB, kuboola/kulemba zinthu zadothi, kudula galasi/safira, kulemba kudula kwa wafer kwa galasi lapadera ndi kulemba chizindikiro cha laser.
Kuyambira mu 2016, msika wa laser ya UV wakunyumba wakhala ukukulirakulira mofulumira. Trumf, Coherent, Spectra-Physics ndi makampani ena akunja akutengabe msika wapamwamba kwambiri. Ponena za mitundu yakunyumba, Huaray, Bellin, Inngu, RFH, Inno, Gain Laser ndi omwe amapanga 90% ya gawo la msika pamsika wa laser ya UV wakunyumba.
Mayiko akuluakulu padziko lonse lapansi akufunafuna ukadaulo wapamwamba kwambiri ngati malo atsopano opititsira patsogolo chitukuko. Ndipo China ili ndi ukadaulo wotsogola wa 5G womwe ungapikisane ndi mayiko aku Europe, US ndi Japan. Chaka cha 2019 chinali chaka chomwe ukadaulo wa 5G udagulitsidwa mdziko muno ndipo chaka chino ukadaulo wa 5G wabweretsa kale mphamvu zambiri kumagetsi a ogula.
Masiku ano, China ili ndi ogwiritsa ntchito mafoni opitilira 1 biliyoni ndipo yalowa mu nthawi ya mafoni anzeru. Tikayang'ana mmbuyo pakukula kwa mafoni anzeru ku China, nthawi yomwe ikukula mwachangu kwambiri ndi 2010-2015. Munthawi imeneyi, chizindikiro cholumikizirana chinakula kuchokera pa 2G kupita ku 3G ndi 4G ndipo tsopano 5G ndipo kufunikira kwa mafoni anzeru, mapiritsi, ndi zinthu zovalidwa kunali kuwonjezeka, zomwe zinabweretsa mwayi waukulu kumakampani opanga ma laser. Pakadali pano, kufunikira kwa laser ya UV ndi laser yothamanga kwambiri kukukulirakuliranso.
Malinga ndi sipekitiramu, laser imatha kugawidwa m'magulu a infrared laser, green laser, UV laser ndi blue laser. Potengera nthawi ya pulse, laser imatha kugawidwa m'magulu a microsecond laser, nanosecond laser, picosecond laser ndi femtosecond laser. UV laser imapezeka kudzera mu m'badwo wachitatu wa harmonic wa infrared laser, kotero ndi yokwera mtengo komanso yovuta kwambiri. Masiku ano, ukadaulo wa nanosecond UV laser wa opanga ma laser apakhomo ndi wokhwima kale ndipo msika wa 2-20W nanosecond UV laser ukutengedwa kwathunthu ndi opanga akunyumba. M'zaka ziwiri zapitazi, msika wa UV laser wakhala wopikisana kwambiri, kotero mtengo wake umakhala wotsika, zomwe zimapangitsa anthu ambiri kuzindikira zabwino za UV laser processing. Mofanana ndi infrared laser, UV laser monga gwero la kutentha kwa high usahihi processing ili ndi njira ziwiri zopititsira patsogolo: mphamvu yapamwamba komanso pulse yaifupi.
Pakupanga kwenikweni, kukhazikika kwa mphamvu ndi kukhazikika kwa kugunda kwa UV laser n'kofunikira kwambiri. Chifukwa chake, ndikofunikira kukhala ndi makina odalirika oziziritsira madzi. Pakadali pano, ma laser ambiri a 3W+ UV ali ndi makina oziziritsira madzi kuti atsimikizire kuti UV laser ili ndi mphamvu yowongolera kutentha. Popeza nanosecond UV laser ikadali wosewera wamkulu pamsika wa UV laser, kufunikira kwa makina oziziritsira madzi kupitilira kukula.
Monga kampani yopereka njira zoziziritsira madzi pogwiritsa ntchito laser, S&A Teyu idalimbikitsa ma chiller oziziritsira madzi omwe adapangidwira makamaka UV laser zaka zingapo zapitazo ndipo akutenga gawo lalikulu pamsika pogwiritsa ntchito nanosecond UV laser. Ma RUMP, CWUL ndi CWUP series recirculating UV laser chillers amadziwika bwino ndi ogwiritsa ntchito padziko lonse lapansi.
