I-Pulse kunye neendlela eziqhubekayo zamaza
Inxalenye ebalulekileyo ye-micromachining ye-optical kukudluliselwa kobushushu kwindawo ye-substrate ekufutshane ne-micro-machined material.I-Lasers inokusebenza kwimo ye-pulsed okanye imo eqhubekayo yamaza.Kwimowudi yamaza eqhubekayo, imveliso ye-laser ihlala ihleli ixesha elide.
Kwimo ye-pulsed, i-laser output igxininiswe kwiipulses ezincinci.Izixhobo ze-laser yemodi ye-pulsed zibonelela ngee-pulses kunye ne-pulse encinci ye-pulse yamandla aneleyo e-micromachining yezinto ezinikiweyo.Ubude be-pulse encinci bunciphisa ukuhamba kobushushu kwizinto ezijikelezileyo.I-Laser pulses inokwahluka ngobude ukusuka kwi-milliseconds ukuya kwi-femtoseconds.
Amandla encopho anxulumene nobude bexesha le-laser pulse, ngoko ke ii-laser ze-pulsed zinokufikelela iincopho eziphezulu kakhulu kunamaza aqhubekayo.
Ukusetyenzwa kweLaser ikakhulu kubandakanya ukusebenzisana okukhokelela ekukhutshweni kwezinto ezingaphantsi.Ukudluliselwa kwamandla okwenzekayo kuxhomekeke kwizinto eziphathekayo kunye neempawu ze-laser.Iimpawu zeLaser eziphembelela izinto ziquka amandla aphezulu, ububanzi be-pulse, kunye ne-emission wavelength.Ukuqwalaselwa kwezinto eziphathekayo kukuba ingaba iyakwazi ukufunxa amandla e-laser ngokusebenzisa i-thermal kunye / okanye iinkqubo ze-photochemical.
Kutheni ububanzi be-pulse bubalulekile?
Ukusika kweLaser kucocekile kwaye kuchanekile.Isidingo sokwenza izixhobo ezincinci, ezikhawulezayo, ezikhaphukhaphu nezisezantsi zifuna iilaser ukuhlangabezana nomngeni.I-laser pulsed isetyenziselwa ukuchaneka kwe-micromachining yezinto ezahlukeneyo.Ukukwazi ukuvelisa ububanzi be-pulse eyahlukeneyo ngundoqo wokuchaneka, ukugqithisa, umgangatho kunye nokusebenza kakuhle kweendleko.
Iilaser zeNanosecond zisebenzisa amandla aphakathi afanayo kunye namazinga aphezulu okususwa kwezinto kwaye ngenxa yoko i-output ephezulu kune-picosecond kunye ne-laser ye-femtosecond.
I-picosecond kunye ne-laser ye-femtosecond inyibilika imathiriyeli ukuyisusa ngenkqubo yokuphunga kunye nokunyibilika kwezinto ukuyikhupha.Oku kunyibilika kunokuchaphazela ukuchaneka kunye nomgangatho womatshini, njengoko izinto ezisusiweyo zinokubambelela emaphethelweni kwaye ziqinise.
Ukuqhubela phambili kwitekhnoloji ye-laser ye-pulsed kwenze ukuba kube lula ukusebenzisa i-micromachining kwizixhobo ezincinci, njengezixhobo zonyango, ezinomonakalo omncinci kwizinto ezingqongileyo.Ngenkqubela phambili yesayensi ekhawulezileyo kwibala le-lasers, ubuchule be-laser micromachining bubalulekile.
Inkqubo yokuvelisa umatshini ibhekiselele kuyo yonke inkqubo yokwenza imveliso kwizinto ezikrwada (okanye iimveliso ezigqityiweyo).Ukuveliswa komatshini, kubandakanya ukuthuthwa kunye nokugcinwa kwezinto eziluhlaza, ukulungiswa kwemveliso, ukuveliswa okungenanto, ukucutshungulwa kweengxenye kunye nokuphathwa kobushushu, indibano yemveliso, kunye nokulungiswa, ukupeyinta kunye nokupakishwa, njl njl. Umxholo wenkqubo yokuvelisa ininzi kakhulu.Amashishini anamhlanje asebenzisa imigaqo kunye neendlela zobunjineli beenkqubo ukuququzelela kunye nokukhokela imveliso, kwaye athathe inkqubo yemveliso njengenkqubo yemveliso enegalelo kunye nemveliso.
