Ukuqopha vs. Ukucutshungulwa Kwe-Laser: Umehluko Obalulekile, Izicelo, kanye Nezidingo Zokupholisa

Emkhakheni obanzi wokucubungula izinto, ukuqopha kanye nokucubungula nge-laser kuvelele njengobuchwepheshe obubili obuhlukile kakhulu futhi obamukelwe kabanzi. Ngayinye iyaziswa ngezimiso zayo zokusebenza ezihlukile, ukuhambisana kwezinto, amakhono okunemba, kanye nezimo zokusetshenziswa eziguquguqukayo. Ukuqonda umehluko wazo kusiza abakhiqizi ukukhetha inqubo efanele kakhulu yezidingo ezithile zokukhiqiza.
Lesi sihloko sinikeza ukuqhathanisa okuhlelekile kokuqopha kanye nokucutshungulwa kwe-laser, okuhlanganisa izimiso, izinto zokwakha, ukunemba, izindleko, izinhlelo zokusebenza, kanye nezidingo zokupholisa.

1. Izimiso Zokucubungula
Ukuqopha, okwaziwa nangokuthi ukuqopha kwamakhemikhali, kususa izinto ngokusebenzisa ukusabela kwamakhemikhali phakathi kwento yokusebenza kanye nezixazululo ezibolayo njenge-asidi noma ama-alkali. Imaski (i-photoresist noma ithempulethi yensimbi) ivikela izindawo ezingacutshungulwanga, kuyilapho izindawo eziveziwe zincibilika. Ukuqopha kuvame ukuhlukaniswa kanje: 1) Ukuqopha okumanzi, okusebenzisa amakhemikhali aketshezi. 2) Ukuqopha okomile, okuncike ekuphenduleni okusekelwe ku-plasma.
Ngokuphambene nalokho, ukucubungula nge-laser kusebenzisa umsebe we-laser onamandla aphezulu, njenge-CO2, i-fiber, noma i-UV lasers, ukuze kukhanye ubuso bezinto ezibonakalayo. Ngemiphumela yokushisa noma ye-photochemical, izinto ziyancibilika, zishise, noma zibole. Izindlela ze-laser zilawulwa ngedijithali, okuvumela ukususwa kwezinto ezingathintani, ezenzakalelayo kakhulu, futhi ezinembile ngaphandle kwamathuluzi angokomzimba.

2. Izinto Ezisebenzayo
Ukuqopha kufaneleka kakhulu ku:
* Izinsimbi (ithusi, i-aluminium, insimbi engagqwali)
* Ama-semiconductor (ama-silicon wafer, ama-chips)
* Ingilazi noma izinto zobumba (ezinezingcezu ezikhethekile)
Kodwa-ke, ayisebenzi kahle ezintweni ezingamelani nokugqwala njenge-titanium alloys.

Ukucubungula nge-laser kunikeza ukuhambisana okubanzi kwezinto ezibonakalayo, okuhlanganisa:
* Izinsimbi kanye nama-alloy
* Amapulasitiki nama-polymer
* Izinkuni, isikhumba, izinto zobumba, kanye nengilazi
* Izinto ezithambile (isb., i-sapphire) kanye nezinhlanganisela
Ukuze uthole izinto ezikhanyisa kakhulu noma ezishisa kakhulu (njengethusi noma isiliva elihlanzekile), imithombo ekhethekile ye-laser ingadingeka.

3. Ukucubungula Okunembile
Ukuqopha ngokuvamile kufeza ukunemba kwezinga le-micron (1–50 μm), okwenza kube kuhle kakhulu kumaphethini amahle njengezifunda ze-PCB. Kodwa-ke, ukusika okungaphansi kwe-lateral kungenzeka, okuholela emaphethelweni anciphile noma anisotropic.
Ukucutshungulwa nge-laser kungafinyelela ukunemba kwe-sub-micron, ikakhulukazi ekusikeni nasekubholeni. Imiphetho ivame ukuba mikhulu futhi ichazwe kahle, yize izindawo ezithintekile ekushiseni zingabangela imifantu emincane noma i-slag kuye ngemingcele nohlobo lwezinto.

4. Isivinini Sokucubungula kanye Nezindleko
Ukuqopha kufaneleka kahle ekukhiqizweni okukhulu, njengoba izingxenye eziningi zingacutshungulwa ngasikhathi sinye. Kodwa-ke, izindleko zokwenziwa kwemaski kanye nokwelashwa kwemfucuza yamakhemikhali kukhulisa izindleko zokusebenza zizonke.
Ukucutshungulwa kwe-laser kuhamba phambili ekukhiqizweni okwenziwe nge-single-piece noma nge-small-batch. Ivumela ukusethwa okusheshayo, i-prototyping esheshayo, kanye nokulungiswa kwamapharamitha edijithali ngaphandle kwe-molds noma i-masks. Nakuba imishini ye-laser imele ukutshalwa kwezimali okuphezulu kokuqala, isusa imfucuza yamakhemikhali, yize izinhlelo zokukhipha intuthu zivame ukudingeka.

5. Izicelo Ezijwayelekile
Izinhlelo zokusebenza zokuqopha zifaka:
* Ukukhiqiza izinto zikagesi (ama-PCB, ama-semiconductor chips)
* Izingxenye zokunemba (izihlungi zensimbi, amapuleti anezimbobo ezincane)
* Imikhiqizo yokuhlobisa (izimpawu zensimbi engagqwali, ingilazi yobuciko)
Izinhlelo zokusebenza zokucubungula nge-laser zifaka:
* Ukumaka nokuqopha (amakhodi e-QR, ama-logo, izinombolo ze-serial)
* Ukusika (amashidi ensimbi ayinkimbinkimbi, amaphaneli e-acrylic)
* Umshini omncane (ukubhoboza idivayisi yezokwelapha, ukusika izinto ezibuthakathaka)

6. Izinzuzo kanye nemikhawulo ngokushesha
Ukuqopha kuyasebenza ekukhiqizeni amaphethini anembe kakhulu ngamanani amakhulu, uma nje izinto zihambisana namakhemikhali. Umkhawulo wayo oyinhloko usekuthintekeni kwemvelo ngenxa yokungcola kwamakhemikhali.
Ukucubungula nge-laser kunikeza ukuguquguquka okukhulu kwezinto, ikakhulukazi ezingezona izinsimbi, futhi kusekela ukukhiqizwa okuguquguqukayo, okungenakungcola. Kulungele ukwenza ngokwezifiso kanye nokukhiqizwa kwedijithali, yize ukujula kokucubungula ngokuvamile kulinganiselwe futhi izici ezijulile zingadinga ukudlula okuningi.

7. Indlela Yokukhetha Ubuchwepheshe Obufanele
Ukukhetha phakathi kokuqopha kanye nokucutshungulwa nge-laser kuncike ezidingweni zohlelo lokusebenza:
* Khetha ukuqopha ukuze kukhiqizwe ngobuningi obukhulu amaphethini amahle, afanayo ezintweni ezihambisana namakhemikhali.
* Khetha ukucutshungulwa nge-laser kwezinto eziyinkimbinkimbi, ukwenza ngokwezifiso kweqembu elincane, noma ukukhiqiza okungathintani.
Ezimweni eziningi, lobu buchwepheshe obubili bungahlanganiswa—isibonelo, ukusebenzisa ukucubungula nge-laser ukudala izifihla-buso zokuhlikihla, kulandelwe ukuhlunga ngamakhemikhali ukuze kucutshungulwe kahle endaweni enkulu. Le ndlela ehlanganisiwe isebenzisa amandla azo zombili izindlela.

8. Ingabe Lezi Zinqubo Zidinga I-Water Chiller?
Ukuthi ukugcaba kudinga i-chiller kuncike ekuzinzeni kwenqubo kanye nezidingo zokulawula izinga lokushisa.
Ukuze kucutshungulwe nge-laser, i -water cooler ibalulekile. Ukupholisa okufanele kuqinisekisa ukuzinza kokukhishwa kwe-laser, kugcina ukunemba kokucubungula, futhi kwandisa kakhulu impilo yesevisi yemithombo ye-laser kanye nezingxenye ze-optical.

Isiphetho
Kokubili ukucutshungulwa kwe-etching kanye ne-laser kunikeza izinzuzo ezihlukile futhi kufeza izidingo ezahlukene zezimboni. Ngokuhlola izakhiwo zezinto ezibonakalayo, umthamo wokukhiqiza, izidingo zokunemba, kanye nokucatshangelwa kwemvelo, abakhiqizi bangakhetha ubuchwepheshe bokucubungula obufanele kakhulu noma bahlanganise kokubili ukuze bafinyelele ikhwalithi ephezulu kanye nokusebenza kahle.
