Kodi Mungatani Kuti Mugwiritse Ntchito Msika Wogwiritsa Ntchito Zipangizo Zapamwamba za Laser za Ultrafast?

Kukonza laser m'mafakitale kuli ndi makhalidwe atatu ofunikira: kugwira ntchito bwino kwambiri, kulondola, komanso khalidwe labwino kwambiri. Ndi makhalidwe atatuwa omwe apangitsa kuti kukonza laser kugwiritsidwe ntchito kwambiri m'magawo osiyanasiyana opanga. Kaya ndi kudula zitsulo mwamphamvu kwambiri kapena kukonza pang'ono pamlingo wapakati mpaka wotsika, njira za laser zawonetsa zabwino zazikulu kuposa njira zachikhalidwe zopangira. Chifukwa chake, kukonza laser kwagwiritsidwa ntchito mwachangu komanso mofala m'zaka khumi zapitazi kapena kuposerapo.

Kukula kwa Ma Laser Othamanga Kwambiri ku China

Ma laser processing processing asintha pang'onopang'ono, akuyang'ana kwambiri ntchito zosiyanasiyana monga kudula kwa laser ya ulusi wapakati ndi wamphamvu kwambiri, kuwotcherera zigawo zazikulu zachitsulo, ndi zinthu zolondola za laser ya ultrafast micro-processing. Ma laser a Ultrafast, omwe amaimiridwa ndi ma picosecond laser (masekondi 10-12) ndi ma femtosecond laser (masekondi 10-15), asintha kwambiri pazaka 20 zokha. Anayamba kugwiritsidwa ntchito m'malonda mu 2010 ndipo pang'onopang'ono analowa m'magawo azachipatala ndi mafakitale. China inayamba kugwiritsa ntchito ma laser a ultrafast mu 2012 m'mafakitale, koma zinthu zokhwima zinangoyamba kumene pofika mu 2014. Izi zisanachitike, pafupifupi ma laser onse a ultrafast anali ochokera kunja.

Pofika chaka cha 2015, opanga akunja anali ndi ukadaulo wokhwima, komabe mtengo wa ma laser othamanga kwambiri unapitirira ma yuan 2 miliyoni aku China. Makina odulira laser olondola kwambiri anagulitsidwa pamtengo woposa ma yuan 4 miliyoni. Mtengo wokwera unalepheretsa kugwiritsa ntchito ma laser othamanga kwambiri ku China. Pambuyo pa 2015, China inafulumizitsa kugulitsidwa kwa ma laser othamanga kwambiri. Kupita patsogolo kwaukadaulo kunachitika mwachangu, ndipo pofika chaka cha 2017, makampani opitilira khumi aku China a ultrafast laser anali kupikisana mofanana ndi zinthu zakunja. Ma laser othamanga kwambiri opangidwa ku China anali ndi mtengo wa ma yuan zikwizikwi zokha, zomwe zinapangitsa kuti zinthu zomwe zinatumizidwa kunja zichepetse mitengo yawo moyenera. Panthawiyo, ma laser othamanga kwambiri opangidwa mdziko muno adakhazikika ndikupeza mphamvu mu gawo lamphamvu yochepa (3W-15W). Kutumiza kwa ma laser othamanga kwambiri aku China kunakwera kuchoka pa mayunitsi osakwana 100 mu 2015 kufika pa mayunitsi 2,400 mu 2021. Mu 2020, msika wa laser wothamanga kwambiri waku China unali pafupifupi ma yuan 2.74 biliyoni.

Mphamvu ya Ma Laser Othamanga Kwambiri Ikupitirirabe Kufika Pamwamba

M'zaka zaposachedwapa, chifukwa cha khama la ofufuza ku China, pakhala kupita patsogolo kwakukulu mu ukadaulo wa laser wopangidwa ku China wa ultrafast: chitukuko chopambana cha laser ya 50W ultraviolet picosecond ndi kukula pang'onopang'ono kwa laser ya femtosecond ya 50W. Mu 2023, kampani yochokera ku Beijing idayambitsa laser ya 500W ya infrared picosecond yamphamvu kwambiri. Pakadali pano, ukadaulo wa laser wothamanga kwambiri ku China wachepetsa kwambiri kusiyana ndi milingo yapamwamba ku Europe ndi United States, zomwe zikutsalira pazizindikiro zazikulu monga mphamvu yayikulu, kukhazikika, ndi m'lifupi mwa kugunda kwa mtima kochepa.

Kukula kwa ma laser othamanga kwambiri komwe kukuyembekezeredwa mtsogolo kukupitilirabe kuyang'ana kwambiri pakuyambitsa mitundu yamphamvu kwambiri, monga 1000W infrared picosecond ndi 500W femtosecond laser, ndi kusintha kosalekeza kwa pulse width. Pamene ukadaulo ukupita patsogolo, zovuta zina zomwe zikugwiritsidwa ntchito zikuyembekezeka kuthetsedwa.

Kufunika kwa Msika Wapakhomo ku China Kukuyambitsa Kukula kwa Mphamvu Yopanga Laser

Kukula kwa msika wa laser wothamanga kwambiri ku China kukucheperachepera kwambiri poyerekeza ndi kuchuluka kwa katundu wotumizidwa. Kusiyana kumeneku kumachokera makamaka ku mfundo yakuti msika wogwiritsa ntchito laser wothamanga kwambiri ku China sunatsegulidwe mokwanira. Mpikisano waukulu pakati pa opanga laser akunyumba ndi akunja, akuchita nawo nkhondo zamitengo kuti atenge gawo pamsika, kuphatikiza njira zambiri zosakhwima kumapeto kwa pulogalamuyo komanso kuchepa kwa msika wamagetsi amafoni/ma panel m'zaka zitatu zapitazi, kwapangitsa ogwiritsa ntchito ambiri kukayikira kukulitsa kupanga kwawo pa mizere ya laser yothamanga kwambiri.

Mosiyana ndi kudula ndi kuwotcherera kwa laser kooneka bwino mu chitsulo cha pepala, luso lokonza la ma laser othamanga kwambiri limamaliza ntchito munthawi yochepa kwambiri, zomwe zimafuna kafukufuku wambiri m'njira zosiyanasiyana. Pakadali pano, nthawi zambiri timatchula kuti ma laser othamanga kwambiri ali ndi ntchito zokhwima podula mafoni anzeru, magalasi, filimu ya OLED PET, ma FPC flexible board, ma PERC solar cells, kudula ma wafer, ndi kuboola mabowo akhungu m'mabwalo a circuit, pakati pa madera ena. Kuphatikiza apo, kufunika kwawo kumaonekera m'magawo a ndege ndi chitetezo pakuboola ndi kudula zida zapadera.

Ndikofunika kudziwa kuti ngakhale kuti akuti ma laser othamanga kwambiri ndi oyenera m'magawo ambiri, kugwiritsa ntchito kwawo kwenikweni sikuli nkhani yosiyana. M'mafakitale omwe amapanga zinthu zambiri monga zinthu za semiconductor, tchipisi, ma wafer, ma PCB, ma board a copper-clad, ndi SMT, pali ntchito zochepa, ngati zilipo, za ma laser othamanga kwambiri. Izi zikutanthauza kuchedwa pakukula kwa ntchito ndi njira za laser zothamanga kwambiri, zomwe zikutsalira kumbuyo kwa kupita patsogolo kwa ukadaulo wa laser.

Ulendo Wautali Wofufuza Mapulogalamu mu Ultrafast Laser Processing

Ku China, chiwerengero cha makampani omwe amagwira ntchito yokonza zida za laser molondola ndi chochepa, chomwe chimawerengera pafupifupi 1/20 ya makampani odulira zitsulo za laser. Makampaniwa nthawi zambiri si akuluakulu ndipo ali ndi mwayi wochepa wopanga njira m'mafakitale monga ma chips, ma PCB, ndi mapanelo. Kuphatikiza apo, mafakitale omwe ali ndi njira zopangira zokhwima mu ntchito zama terminal nthawi zambiri amakumana ndi mayesero ambiri komanso kutsimikizika akasintha kupita ku laser micro-processing. Kupeza njira zatsopano zodalirika zogwirira ntchito kumafuna kuyesa ndi kulakwitsa kwakukulu, poganizira mtengo wa zida. Kusinthaku si njira yophweka.

Kudula magalasi onse kungakhale njira yabwino yolowera ma laser a ultrafast mu niche inayake. Kugwiritsa ntchito mwachangu kudula kwa laser kwa zikwangwani zagalasi zoyenda ndi chitsanzo chabwino. Komabe, kufufuza ma laser a ultrafast pazinthu zapadera kapena zinthu zomwe sizinamalizidwe bwino m'mafakitale ena kumafuna nthawi yochulukirapo yofufuza. Pakadali pano, kugwiritsa ntchito ma laser a ultrafast kumakhalabe kochepa, makamaka kuyang'ana kwambiri kudula zinthu zopanda chitsulo. Pali kusowa kwa kugwiritsa ntchito m'magawo akuluakulu monga ma OLED/semiconductors, zomwe zikusonyeza kuti ukadaulo wonse wa ultrafast laser ku China sunakwerebe. Izi zikutanthauzanso kuthekera kwakukulu kwa chitukuko chamtsogolo, ndi kuwonjezeka pang'onopang'ono kwa ntchito zokonza ma laser a ultrafast m'zaka khumi zikubwerazi.
