Njengoba sonke sazi, i-chip ye-LED njengengxenye eyinhloko yesibani se-LED iyidivayisi ye-semiconductor yesimo esiqinile, inhliziyo ye-LED iyi-chip ye-semiconductor, umkhawulo owodwa we-chip unamathiselwe kubakaki, umkhawulo owodwa uyi-electrode engalungile, enye i-electrode ixhunywe ku-electrode eqondile yomthombo wamandla, ukuze yonke i-chip ifakwe kabusha nge-ecapsulated. Lapho isafire isetshenziswa njenge-substrate material, isetshenziswa kabanzi ekukhiqizeni ama-chips e-LED, futhi ithuluzi lokusika lendabuko alisakwazi ukuhlangabezana nezidingo zokusika. Ngakho uyixazulula kanjani le nkinga?
Umshini wokusika we-picosecond laser we-wavelength omfishane ungasetshenziswa ukusika ama-wafers esafire, okuxazulula ngempumelelo ubunzima bokusika isafire kanye nezidingo zemboni ye-LED ukwenza i-chip ibe mncane nendlela yokusika ibe mncane, futhi inikeza ithuba nesiqiniseko sokusika okuphumelelayo kokukhiqizwa kwenqwaba ye-LED esekelwe kusafire.
Izinzuzo zokusika kwe-laser:
I-1, ikhwalithi enhle yokusika: ngenxa yendawo encane ye-laser, ukuminyana kwamandla aphezulu, isivinini sokusika, ngakho ukusika kwe-laser kungathola ikhwalithi engcono yokusika.
I-2, ukusebenza kahle kokusika: ngenxa yezimpawu zokudlulisela ze-laser, umshini wokusika we-laser ngokuvamile uhlome amatafula amaningi okulawula izinombolo, futhi yonke inqubo yokusika ingaba yi-CNC ngokugcwele. Uma usebenza, vele ushintshe uhlelo lokulawula izinombolo, lungasetshenziswa ekusikeni izingxenye zomumo ohlukene, kokubili ukusika kwezinhlangothi ezimbili kanye nokusikwa kwe-three-dimensional kungafinyelelwa.
I-3, ijubane lokusika liyashesha: impahla ayidingi ukulungiswa ekusikeni kwe-laser, okungagcina ukulungiswa nokugcina isikhathi esiyisizayo sokulayisha nokukhipha.
I-4, ukusika okungathinteki: ithoshi yokusika i-laser kanye ne-workpiece akukho othintana naye, akukho ukugqoka kwamathuluzi. Ukucubungula izingxenye zomumo ohlukene, akudingi ukufaka esikhundleni "ithuluzi", vele uguqule imingcele yokuphuma kwe-laser. Inqubo yokusika i-laser inomsindo ophansi, ukudlidliza okuphansi futhi akukho ukungcola.
5, kunezinhlobo eziningi zezinto zokusika: zezinto ezahlukahlukene, ngenxa yezakhiwo zazo ezishisayo zomzimba kanye namazinga ahlukene okumuncwa kwe-laser, akhombisa ukuguquguquka okuhlukile kokusika kwe-laser.
