Njengoko sonke sisazi, i-chip ye-LED njengenxalenye engundoqo yesibane se-LED sisixhobo se-semiconductor yesimo esiqinileyo, intliziyo ye-LED yi-chip ye-semiconductor, enye isiphelo se-chip sincanyathiselwe kwisibiyeli, enye isiphelo yi-electrode engalunganga, esinye isiphelo siqhagamshelwe kwi-electrode efanelekileyo yonikezelo lwamandla, ukuze yonke i-chippoxy ifakwe kwi-ecapsulated. Xa isafire isetyenziswe njenge-substrate material, isetyenziswa ngokubanzi kwimveliso ye-chips ze-LED, kwaye isixhobo sokusika esiqhelekileyo asikwazi ukuhlangabezana neemfuno zokusika. Uyisombulula njani ke le ngxaki?
Umatshini wokusika omfutshane we-picosecond laser ungasetyenziselwa ukusika ii-wafers zesafire, ezisombulula ngokufanelekileyo ubunzima bokusika isafire kunye neemfuno zeshishini le-LED ukwenza i-chip encinci kunye nendlela yokusika emxinwa, kwaye ibonelela ngokunokwenzeka kunye nesiqinisekiso sokusika ngokufanelekileyo ukuveliswa kobunzima obukhulu be-LED esekelwe kwisafire.
Izinto ezilungileyo zokusika i-laser:
I-1, umgangatho olungileyo wokusika: ngenxa yendawo encinci ye-laser, ubuninzi bamandla aphezulu, isantya sokusika, ngoko ukusika kwe-laser kunokufumana umgangatho ongcono wokusika.
I-2, ukusebenza kakuhle kokusika: ngenxa yeempawu zokuhanjiswa kwe-laser, umatshini wokusika we-laser uxhotyiswe ngokuqhelekileyo ngeetafile zokulawula amanani amaninzi, kwaye yonke inkqubo yokusika ingaba yi-CNC ngokupheleleyo. Xa usebenza, vele utshintshe inkqubo yokulawula amanani, ingasetyenziselwa ukusika iinxalenye zeemilo ezahlukeneyo, zombini ukusika kunye nokusika okuthathu kunokufezekiswa.
I-3, isantya sokusika sikhawuleza: izinto eziphathekayo azidingi ukulungiswa kwi-laser cutting, enokugcina ukulungiswa kunye nokugcina ixesha elincedisayo lokulayisha kunye nokukhulula.
I-4, i-non-contact cut cut: itotshi yokusika i-laser kunye ne-workpiece akukho mnxibelelwano, akukho mpahla yokunxiba. Ukucutshungulwa kweengxenye zeemilo ezahlukeneyo, akufuneki ukuba utshintshe "isixhobo", tshintsha nje iiparitha zokuphuma kwelaser. Inkqubo yokusika i-Laser inengxolo ephantsi, i-vibration ephantsi kwaye akukho ngcoliseko.
I-5, kukho iintlobo ezininzi zezinto zokusika: kwizinto ezahlukeneyo, ngenxa yeempawu zabo zomzimba ezishisayo kunye namazinga ahlukeneyo okufunxa kwe-laser, abonisa ukuguquguquka kokusika kwe-laser.
