Femtosecond vs Nanosecond Laser Micro-Drilling|Phau Ntawv Qhia Precision

Nyob rau hauv lub ntiaj teb hloov zuj zus mus sai heev ntawm precision manufacturing, kev xaiv ntawm nanosecond thiab femtosecond laser tshuab yuav ua tau los yog ua txhaum koj micro-machining project. Raws li kev lag luam thawb mus rau ib txwm muaj - cov yam ntxwv me me thiab kev ua siab ntev dua -los ntawm cov ntim khoom ntim rau cov khoom siv kho mob- lo lus nug tsis yog xwbsebsiv laser drilling, tab sisuaslaser tshuab yuav xa cov precision koj daim ntawv thov xav tau.

Txawm hais tias ob qho tib si nanosecond thiab femtosecond lasers tuaj yeem tsim micro- qhov, lawv qhov sib txawv hauv lub sijhawm mem tes ua rau cov txiaj ntsig sib txawv. Ib qho tso siab rau thermal ablation, inevitably tawm hauv tshav kub- thaj chaw cuam tshuam, cov txheej txheem rov ua dua, thiab micro- tawg. Lwm qhov ua tiav "txias machining" los ntawm ultrafast ionization, xa pristine, burr - dawb qhov nrog micron - qib precision.

Hauv qhov kev sib piv no, peb yuav tshuaj xyuas qhov tseeb -world machining results side-los ntawm -sab, txheeb xyuas ib qho -qhov morphology, array zoo, core operating hauv paus ntsiab lus, thiab kev lag luam- tshwj xeeb daim ntawv thov. Txawm hais tias koj tab tom ntsuas tus nqi-txoj kev ntxhib ntxhib los yog xav tau sub-micron precision rau siab- cov khoom siv thev naus laus zis, kev nkag siab txog qhov sib txawv tseem ceeb no yuav pab koj txiav txim siab paub qhov sib npaug ntawm kev ua tau zoo, zoo, thiab pob nyiaj siv.

Cia peb dhia dej rau hauv cov ntaub ntawv thiab tshawb pom yog vim li cas femtosecond kiv puag ncig yog hloov precision micro-machining thoob plaws aerospace, kev kho mob, semiconductor, thiab optical industries.

Sab laug: Nanosecond Laser Machined Micro- qhov

• Cov cheeb tsam loj ntawm melting thiab recast txheej rau ntawm phab ntsa sab hauv, yoj-zoo li qhov tawg burrs, thiab hnyav charring thiab puas ntawm cov npoo.
• Cov txheej txheem machining tsim ib qho tseem ceeb Thaum tshav kub kub cuam tshuam cheeb tsam (HAZ). Cov khoom melts, vaporizes, thiab splashes vim cua sov, tsim ib txheej txheej ntawm thermal puas.
• Tsis zoo sib xws nyob rau hauv lub qhov taub, tsis tshua muaj siab puab phab ntsa roughness, thiab muaj ntau cov kab nrib pleb thiab molten residue.

Sab xis: Femtosecond Laser Machined Micro- qhov

• Cov phab ntsa du thiab ntsug, tsis muaj melting los yog tawg, thiab tsis muaj ntug chipping los yog burrs.
• Tag nrho cov txheej txheem yog "txias machining" uas tsis muaj cua sov conduction, ua rau yuav luag xoom Heat Affected Zone (HAZ). Cov khoom raug tshem tawm ntawm ultrafast txias ionization (ablation).
• Lub qhov tsis tu ncua nrog zoo cylindricity; cov phab ntsa sab hauv yog dawb ntawm cov txheej txheem rov qab thiab tawg puas tsuaj.

Nanosecond Laser:

Qhov saum npoo nthuav dav thaj chaw loj ntawm blackening thiab carbonization, nrog rau kev sib sau ntawm splashed residue nyob ib ncig ntawm lub periphery. Muaj qhov sib txawv tseem ceeb ntawm tus kheej qhov ntau thiab tsawg, thiab cov qauv array yog distorted heev. Qhov qhib qhov qhib qhia tias melting thiab cov ntaub ntawv dhau, nrog loj - cheeb tsam thermal burning ntawm lub substrate. Cov tsis xws luag muaj xws li dav ntug chipping, clogged qhov, thiab kev puas tsuaj rau cov khoom siv substrate.

Nanosecond Laser Processing Effect Femtosecond Laser Ua nyhuv

Femtosecond Laser:

Lub substrate nto yog huv si tsis muaj burning los yog discoloration. Qhov diameters thiab pitch thoob plaws tag nrho cov array yog heev sib xws thiab tsis tu ncua. Lub qhov qhib yog qhov ntse uas tsis muaj cov khoom siv dhau los, thiab tsis muaj cov kab mob peripheral thermal. Tsis muaj cua sov-vim qhov tsis xws luag, ua rau muaj qhov ua tau zoo tshaj plaws rau cov khoom tiav.

1. Nanosecond Laser: Pulse duration yog nyob rau theem nanosecond; Cov txheej txheem belongs rau thermal ablation.

Lub zog tsis tu ncua nkag mus rau hauv cov khoom siv sab hauv, ua rau cua sov kom diffuse thiab coj mus rau ntau yam. Qhov no ua rau tsis muaj kev puas tsuaj rau thermal puas xws li melting, vaporization, recasting, cracking, thiab thermal deformation. Nws yog tsis yooj yim sua kom tsis txhob muaj teeb meem xws li burrs thiab ntug vau.

2. Femtosecond Laser: Pulse duration yog femtosecond (10⁻¹⁵ vib nas this), uas yog ultra- luv thiab ultra- nrawm.

Lub zog ncov instantaneous yog siab heev. Cov khoom siv ionization thiab ablation ua tiav ua ntej tshav kub tuaj yeem cuam tshuam rau cov khoom nyob ib puag ncig, ua tiav tsis yog -thermal "txias" ua. Qhov no tshem tawm tag nrho cov teebmeem thermal, cov txheej txheem rov ua dua, thiab chipping / burrs, ua rau cov khoom loj ntawm micron meej heev - qhov ntawm micron / sub- qib micron.

Nanosecond Laser: Tsuas yog tsim nyog rau qis -precision, qis- tus nqi ntxhib drilling scenarios. Nws yog siv rau qhov uas tsis muaj kev txwv nruj rau sab hauv phab ntsa zoo lossis tsis yog - ua haujlwm thermal.

Micro-precision Laser Txiav & Drilling Tshuab

Femtosecond Laser: Tshwj xeeb rau siab - thev naus laus zis xws li cov ntim ntim, cov khoom siv kho mob / cov khoom siv roj ntsha, cov khoom siv hauv aerospace precision, optical nyias films, thiab ultra- cov ntaub ntawv tshwj xeeb nyias. Nws yog siv rau kev cai ua ntawm micro- qhov / qhov muag tsis pom - qhov arrays.
