Cishe ingxenye ngayinye ye-Printed Circuit Board (PCB) ihilela indlela yokumaka cishe noma kancane. Lokho kungenxa yokuthi ulwazi oluphrintiwe ku-PCB lungafeza umsebenzi wokulandelela ikhwalithi, ukuhlonza okuzenzakalelayo kanye nokukhuthazwa komkhiqizo. Lolu lwazi lwalunyatheliswa yimishini yokunyathelisa yendabuko. Kodwa imishini yokunyathelisa yendabuko isebenzisa izinto eziningi ezingasetshenziswa ezingadala ukungcola kalula. Futhi ulwazi abalunyathelisayo luyanyamalala njengoba isikhathi sihamba, okuyinto engasizi kakhulu.
Kodwa ngomshini wokumaka nge-laser, lezo zinkinga azisezona izinkinga. Umshini wokumaka nge-laser unenqubo yokungathintani, isivinini esikhulu, akukho okudliwayo futhi akukho ukungcola. Ungaveza izimpawu ezicacile, ezinembile nezihlala isikhathi eside ngefomethi encane kakhulu efika ku-3x3mm. Ngaphandle kwalokho, njengoba ungenakho ukuthintana okuqondile, ngeke udale umonakalo kwi-PCB.
Imishini evamile yokumaka i-laser ye-PCB inikwa amandla yi-laser ye-CO2 kanye ne-UV. Ngaphansi kokucushwa okufanayo, umshini wokumaka i-laser ye-UV unokunemba okuphezulu kunomshini wokumaka i-laser ye-CO2. Ubude be-wave ye-laser ye-UV bungama-355nm futhi iningi lezinto lingamunca kangcono ukukhanya kwe-laser ye-UV kunokukhanya kwe-infrared. Ngaphezu kwalokho, i-laser ye-CO2 uhlobo lokucubungula ukushisa ukuze kutholakale umphumela wokumaka. Ngakho-ke, kulula ukwenzeka nge-carbonization, okuyinto eyingozi ezintweni eziyisisekelo ze-PCB. Ngokuphambene nalokho, i-laser ye-UV "iyindlela yokucubungula ebandayo", ngoba yenza umphumela wokumaka ngokuphula isibopho samakhemikhali ngokukhanya kwe-laser ye-UV. Ngakho-ke, i-laser ye-UV ngeke ilimaze i-PCB.
Njengoba sazi, i-PCB incane kakhulu ngobukhulu futhi ulwazi lokumaka kuyo alulula. Kodwa i-UV laser iyakwazi ukukwenza ngendlela eqondile. Lokhu akubangelwa nje kuphela yisici esiyingqayizivele somshini wokumaka i-UV laser kodwa futhi nohlelo lokupholisa oluhambisana nalo. Uhlelo lokupholisa oluqondile lubaluleke kakhulu ekugcineni izinga lokushisa le-UV laser ukuze i-UV laser isebenze kahle esikhathini eside. Iyunithi ye-S&A Teyu compact chiller CWUL-05 ivame ukusetshenziswa ekupholiseni umshini wokumaka i-UV laser kuma-PCB marking. Le chiller inokuqina kwezinga lokushisa elingu-0.2℃, okusho ukuthi ukushintshashintsha kwezinga lokushisa kuncane kakhulu. Futhi ukushintshashintsha okuncane kusho ukuthi ukuphuma kwe-laser kwe-UV laser kuzozinza. Ngakho-ke, umphumela wokumaka ungaqinisekiswa. Ngaphezu kwalokho, iyunithi ye-CWUL-05 compact water chiller incane kakhulu ngobukhulu, ngakho ayidli isikhala esiningi futhi ingangena kalula ekwakhiweni komshini womshini wokumaka i-PCB laser.
