Niaj hnub nim no, nrog txoj kev tsim txuj tshawb fawb thiab kev siv tshuab, laser technology los kuj tsim txhua yam. Tib lub sijhawm, laser marking cav tau maj mam nkag mus rau ntau yam lag luam kom kos cov khoom. Laser npav yog kev siv ntawm ib qho teeb meem laser los cim cov chaw ruaj khov rau ntau hom khoom sib txawv. Cov cim ntawm kev kos npe yog ua kom pom kev sib sib zog nqus los ntawm cov khoom siv deg, los yog "chiv" cov khoom siv los ntawm kev hloov tshuaj los ntawm lub teeb hluav taws xob, los yog kub nyhiab ntawm qee lub zog los qhia qhov kev ntshaw. Txawv, ntawv nyeem.
Koj puas paub tias lub lens npav ntsiab lus yog dab tsi?
Tam sim no, cov ntsiab cai uas tau lees paub yog ob, "kub ua" thiab "kev ua haujlwm txias".
"Thaum tshav kub kub ua" muaj ib txoj kab teeb meem laser dua (uas yog lub zog ntim zog) uas ci ntsa rau cov khoom ua tiav, thiab cov nplais ntawm cov khoom absorbs laser zog, tsim kev thermal excitation txheej txheem hauv cheeb tsam illuminated, nto ntawm cov khoom siv (los yog txheej) Qhov kub nce, ua rau cov kab mob metamorphosis, yaj, ablation, evaporation, thiab cov zoo li no.
"Cold processing" (ultraviolet) photons nrog high load siab zog tuaj yeem tawg cov khoom pov thaiv hauv cov ntaub ntawv (tshwj xeeb tshaj yog cov khoom siv organic) los yog ib puag ncig tawm los ua rau cov txheej txheem tsis thermal puas. Cov dej num no muaj qhov tshwj xeeb tseem ceeb hauv laser marking processing vim nws tsis yog thermal ablation, tab sis tsis ua "thermal puas" phiv, thiab qhov txias ntawm cov tshuaj qoob loo tawg kom tawg, kom lub puab txheej thiab ze ntawm qhov chaw yuav tsum tau ua tiav yog tsis ua kom kub los yog thermal deformation.
Piv txwv, hauv kev lag luam hauv tshuab hluav taws xob, ib hom yeeb yaj kiab ntawm ib hom khoom tshuaj yog tso rau hauv cov khoom siv substrate los ua ib qho zawj nplhaib nyob rau hauv lub semiconductor substrate.
Lub laser marking tshuab yuav engrave hlau thiab ntau yam uas tsis yog-xim hlau cov ntaub ntawv. Nws yog qhov tsim nyog rau cov ntawv thov uas yuav tsum muaj ntau dua thiab ntau dua qhov kev txiav txim siab. Kev siv hluav taws xob, hluav taws xob, hluav taws xob, hluav taws xob khoom, khoom siv hluav taws xob, cuab yeej cuab tam, cuab kev siv ceev, tsom iav thiab cov sij hawm, cov khoom siv, cov khoom siv yas, cov khoom siv hauv tsev, cov yeeb nkab hauv PVC.
