Cishe ingxenye ngayinye ye-Printed Circuit Board (PCB) ibandakanya inqubo yokumaka engaphezulu noma encane. Lokho kungenxa yokuthi ulwazi oluphrintwe ku-PCB lungabona umsebenzi wokulandelela ukulawula ikhwalithi, ukuhlonza okuzenzakalelayo kanye nokunyuswa komkhiqizo. Lolu lwazi lwaluvame ukuphrintwa yimishini yokuphrinta yendabuko. Kodwa imishini yokunyathelisa yendabuko isebenzisa izinto eziningi ezingasetshenziswa kalula ezingadala ukungcola. Futhi ukwaziswa abakunyathelisayo kuyafiphala njengoba isikhathi sihamba, okungasizi kangako.
Kodwa ngomshini wokumaka we-laser, lezo zinkinga azizona izinkinga. Umshini wokumaka we-laser uhlanganisa ukucutshungulwa okungekona othintana naye, isivinini esikhulu, akukho okudlekayo futhi akukho kungcola. Ingabona amamaki acacile, anembile futhi ahlala isikhathi eside kufomethi encane kakhulu efika ku-3x3mm. Ngaphandle kwalokho, njengoba ingenakho ukuthintana okuqondile, ngeke idale umonakalo ku-PCB.
Imishini evamile yokumaka ye-laser ye-PCB inikwa amandla yi-CO2 laser ne-UV laser. Ngaphansi kokucushwa okufanayo, umshini wokumaka we-laser we-UV unokunemba okuphezulu kunomshini wokumaka we-laser CO2. Ubude begagasi be-laser ye-UV bulinganiselwa ku-355nm futhi izinto eziningi zokwakha zingamunca kangcono ukukhanya kwe-laser ye-UV kunokukhanya kwe-infrared. Ngaphezu kwalokho, i-CO2 laser iwuhlobo lokucubungula ukushisa ukuze ubone umphumela wokumaka. Ngakho-ke, i-carbonization kulula ukwenzeka, eyingozi ezintweni eziyisisekelo ze-PCB. Kunalokho, i-laser ye-UV "iwukucubungula okubandayo", ngoba ibona umphumela wokumaka ngokwephula isibopho samakhemikhali ngesibani se-UV laser. Ngakho-ke, i-laser ye-UV ngeke ilimaze i-PCB.
Njengoba sazi, i-PCB incane kakhulu ngosayizi futhi ukumaka ulwazi kuyo akulula. Kodwa i-UV laser iyakwazi ukukwenza ngendlela eqondile. Lokhu akubangelwa kuphela isici esiyingqayizivele somshini wokumaka we-laser we-UV kodwa nohlelo lokupholisa oza nalo. Isistimu yokupholisa enembile ibaluleke kakhulu ekugcineni izinga lokushisa lelaser ye-UV ukuze i-laser ye-UV isebenze kahle esikhathini eside. S&A Iyunithi ye-Teyu compact chiller CWUL-05 ivamise ukusetshenziselwa ukupholisa umshini wokumaka we-UV laser ekumaka kwe-PCB. Le chiller ifaka ukuzinza kwezinga lokushisa elingu-0.2℃, okusho ukuthi ukushintshashintsha kwezinga lokushisa kuncane kakhulu. Futhi ukushintshashintsha okuncane kusho ukuthi ukuphuma kwe-laser ye-UV laser kuzozinza. Ngakho-ke, umphumela wokumaka ungaqinisekiswa. Ngaphezu kwalokho, iyunithi ye-CWUL-05 compact water chiller incane kakhulu ngosayizi, ngakho ayidli isikhala esiningi futhi ingangena kalula esakhiweni somshini womshini wokumaka we-laser we-PCB.
