Chii chinonzi kuchenesa ne laser
Nekuisa simba relaser rakasimba pamusoro pechinhu chakasvibiswa, kuchenesa nelaser kunogona kubvisa tsvina ipapo ipapo pasina kukuvadza maitiro e substrate. Ndiyo sarudzo yakakodzera chizvarwa chitsva chehunyanzvi hwekuchenesa hwemaindasitiri.
Tekinoroji yekuchenesa nelaser yavewo tekinoroji yekuchenesa inokosha zvikuru muindasitiri, kuvaka ngarava, mundege, nedzimwe nzvimbo dzekugadzira zvinhu zvepamusoro-soro, kusanganisira kubvisa tsvina yerabha pamusoro pemaforoma ematairi, kubvisa tsvina yemafuta esilicon pamusoro pefirimu regoridhe, uye kuchenesa kwakanyatsonaka kweindasitiri ye microelectronics.
Maitiro akajairika ekuchenesa ne laser
◾ Kubvisa Pendi
◾ Kubviswa kweOiri
◾ Kubviswa kweOkisidhe
Kune tekinoroji yelaser yakadai sekucheka nelaser, kunyora nelaser, kuchenesa nelaser, uye kusanganisa nelaser, unogona kunge uchiziva izvi asi panewo manyuko elaser ane chekuita nazvo. Pane fomu rekutarisa rayo rine manyuko mana elaser uye zvinhu zvakakodzera uye mashandisirwo akakodzera.
Manyuko mana elaser nezvekuchenesa nelaser
Nekuda kwekusiyana kwema parameter akakosha akadai se wavelength uye simba re laser source dzakasiyana, mwero wekunyudzwa kwezvinhu zvakasiyana uye mavara, saka unofanirwa kusarudza laser source yakakodzera yemuchina wako wekuchenesa laser zvichienderana nezvinodiwa zvekubvisa tsvina.
▶ MOPA Pulse Laser Cleaning
(kushanda pazvinhu zvemarudzi ese)
MOPA laser ndiyo inonyanya kushandiswa pakuchenesa nelaser. MO inomiririra master oscillator. Sezvo MOPA fiber laser system ichigona kuwedzerwa zvichienderana nekwakabva chiratidzo chembeu chakabatana nesystem, hunhu hwakakodzera hwelaser hwakadai sewavelength yepakati, pulse waveform uye pulse width haizochinjwa. Naizvozvo, chiyero chekugadzirisa maparamendi chakakwira uye huwandu hwakakura. Pamamiriro akasiyana ekushandiswa kwezvinhu zvakasiyana, kugona kuchinjika kwakasimba uye nguva yekushanda kwehwindo yakakura, izvo zvinogona kusangana nekucheneswa kwepamusoro kwezvinhu zvakasiyana.
▶ Kuchenesa Fiber Laser Yakasanganiswa
(sarudzo yakanakisisa yekubvisa pendi)
Kuchenesa kweLaser composite kunoshandisa semiconductor continuous laser kugadzira kupisa kunoburitsa, kuitira kuti substrate ichacheneswa itore simba kuti igadzire gasification, uye plasma cloud, uye igadzire kumanikidzwa kwekuwedzera kwekupisa pakati pesimbi nelayer yakasvibiswa, zvichideredza simba rekubatanidza pakati pelayer. Kana sosi yelaser igadzira danda reLaser rine simba guru, vibration shock wave ichabvisa chinonamira nesimba risina simba rekunamatira, kuitira kuti iwane kuchenesa kweLaser nekukurumidza.
Kuchenesa kwakagadzirwa nelaser kunobatanidza mabasa elaser anoramba achienderera mberi uye pulsed laser panguva imwe chete. Kumhanya kwakanyanya, kushanda zvakanaka, uye mhando yekuchenesa yakafanana, pazvinhu zvakasiyana, zvinogonawo kushandisa marefu akasiyana ekuchenesa nelaser panguva imwe chete kuti zvizadzise chinangwa chekubvisa mavara.
Semuenzaniso, pakuchenesa zvinhu zvakakora zvekuputira uchishandisa laser, simba rinobuda ne laser imwe chete rine simba remapundu akawanda uye mutengo wakakwira. Kuchenesa kwakabatana kwe pulsed laser ne semiconductor laser kunogona kuvandudza kunaka kwekuchenesa nekukurumidza uye zvinobudirira, uye hakukanganisi substrate. Pakuchenesa ne laser zvinhu zvinopenya zvakanyanya senge aluminum alloy, laser imwe chete ine mamwe matambudziko akadai se high reflectivity. Kushandisa pulse laser ne semiconductor laser composite cleaning, pasi pesimba re semiconductor laser conduction transmission, kuwedzera simba re oxide layer pamusoro pesimbi, kuitira kuti pulse laser beam ikwanise kubvisa oxide layer nekukurumidza, kuvandudza kushanda kwekubvisa zvinobudirira, kunyanya kushanda kwekubvisa pendi kunowedzerwa kanopfuura kaviri.
▶ Kuchenesa neLaser yeCO2
(sarudzo yakanakisisa yekuchenesa zvinhu zvisiri zvesimbi)
Laser yeCarbon dioxide ilaser yegesi ine gasi reCO2 sechinhu chinoshanda, iyo yakazadzwa negasi reCO2 nemamwe magasi ekubatsira (helium nenitrogen pamwe nehuwandu hushoma hwehydrogen kana xenon). Zvichienderana nehurefu hwayo hwakasiyana, laser yeCO2 ndiyo sarudzo yakanakisa yekuchenesa pamusoro pezvinhu zvisiri zvesimbi zvakaita sekubvisa guruu, chifukidziro neinki. Semuenzaniso, kushandiswa kwelaser yeCO2 kubvisa pendi yakabatana pamusoro pearuminiyamu alloy hakukuvadzi pamusoro pefirimu reanodic oxide, uye hakuderedzi ukobvu hwayo.
▶ Kuchenesa neLaser yeUV
(sarudzo yakanakisisa yemidziyo yemagetsi yepamusoro-soro)
MaLaser eUltraviolet anoshandiswa mukugadzira maLaser micromachining anosanganisira maLaser eExcimer nemaLaser ese eSolid-state. Marefu eLaser eUltraviolet mapfupi, photon imwe neimwe inogona kupa simba rakawanda, inogona kutyora zvakananga zvisungo zvemakemikari pakati pezvinhu. Nenzira iyi, zvinhu zvakaputirwa zvinobviswa pamusoro muchimiro chegasi kana zvidimbu, uye maitiro ese ekuchenesa anogadzira simba shoma rekupisa iro rinongokanganisa nzvimbo diki pane workpiece. Nekuda kweizvozvo, kuchenesa kweUV laser kune zvakanakira zvakasiyana mukugadzira madiki, senge kuchenesa Si, GaN nezvimwe zvinhu zvesemiconductor, quartz, safira nezvimwe zvinhu zve optical, Uye polyimide (PI), polycarbonate (PC) nezvimwe zvinhu zvepolymer, zvinogona kuvandudza mhando yekugadzira.
Laser yeUV inoonekwa senzira yakanakisisa yekuchenesa laser mumunda wemagetsi akanyatsogadzirwa, tekinoroji yayo ye "cold" inonyanya kuzivikanwa haichinje hunhu hwechinhu panguva imwe chete, pamusoro pemachining madiki uye kugadzirisa, inogona kushandiswa zvakanyanya mukutaurirana, optics, mauto, kuferefeta mhosva, zvokurapa nedzimwe nzvimbo. Semuenzaniso, nguva ye5G yakagadzira kudiwa kwemusika kwekugadzirisa FPC. Kushandiswa kwemuchina weUV laser kunoita kuti zvikwanisike kugadzira FPC nezvimwe zvinhu nemazvo.
