Njengoba sonke sazi, i-PCB “iyibhuloho” lokuxhumanisa izingxenye zikagesi ngayinye futhi iyisici esiyinhloko emikhiqizweni kagesi. Inezinhlelo zokusebenza ezahlukahlukene, okuhlanganisa ama-electronic abathengi, ama-electronic ezimoto, ukuxhumana, ezokwelapha, iphrojekthi yezempi, izindiza nokunye. Namuhla, ama-electronic abathengi kanye nama-electronic ezimoto abhekana nentuthuko esheshayo futhi aba yizinkambu eziyinhloko zesicelo. Ngalesi sikhathi, ukushisela kwe-PCB kudonsele ukunaka okukhulu kubakhiqizi be-PCB. Ngakho-ke, hlobo luni lwe-PCB olungasebenza kulo umshini wokushisela nge-laser? Ake sibheke kabanzi ngezansi.
1. Into idinga ukushiselwa
Kusho ukuthi ngaphansi kokushisa okufanele, insimbi ezoncibilikiswa kanye nethini lokunamathisela kungahlangana ndawonye ukuze kube nekhwalithi enhle yekhwalithi ye-alloy. Akuzona zonke izinsimbi ezinokushibilika okuhle. Ukuze kuthuthukiswe ukushibilika kwensimbi, abasebenzisi bangenza ukushibilika kwe-tin noma ukushibilika kwesiliva ensimbini ukuvimbela ukushibilika kobuso bensimbi.
2. Into idinga ukuhlanzeka ebusweni
Ukuze kuhlanganiswe ithini lokunamathisela kanye nezinto ezizoncibilikiswa, ubuso bento budinga ukuhlanzeka. Ngisho nasezintweni ezinhle zokushibilika, ifilimu yokushibilika noma ibala likawoyela lingase livele ebusweni bento. Ngakho-ke, ukuqinisekisa ikhwalithi yokushibilika, ubuso bento kumele buhlanzeke.
3. Sebenzisa i-powder yokukala efanele
Inhloso yempuphu yokukala ukususa ifilimu yokuxilisa entweni ezoshiselwa. Amasu ahlukene okushisela kufanele asebenzise impuphu yokukala ehlukene. Kuma-elekthronikhi anembile okushisela njenge-PCB, i-rosin kufanele isetshenziswe njengempuphu yokukala ukuqinisekisa ukuthembeka kokushisela.
4. Into idinga ukufudunyezwa kufike ezingeni lokushisa elifanele
Uma izinga lokushisa lokushisela liphansi kakhulu, i-alloy ayikwazi ukwakheka. Futhi uma izinga lokushisa lokushisela liphezulu kakhulu, i-welding flux izohlala isesimweni esingeyona i-eutectic, okuzonciphisa ikhwalithi ye-welding flux futhi esimweni esibi kakhulu, i-pad ku-PCB izokwehla.
5. Ukushisela kudinga isikhathi esifanele
Isikhathi sokushisela sisho isikhathi esichithwa ekusabeleni kwamakhemikhali nangokomzimba enkambisweni yokushisela. Ngemva kokunquma izinga lokushisa lokushisela, abasebenzisi kufanele banqume isikhathi esifanele sokushisela ngokusekelwe ekubunjweni, ikhwalithi kanye nezici zezinto ezizoshiselwa. Uma isikhathi sokushisela side kakhulu, izingxenye noma izingxenye ezishisiwe kulula ukuzilimaza. Ngokuvamile, indawo ngayinye akufanele ithathe imizuzwana engaphezu kwemi-5 ngesikhathi.
Ukuze ugcine umshini wokushisela we-laser we-PCB usezingeni eliphezulu, udinga ukupholiswa kahle yi-industrial chiller. I-S&A Teyu ibilokhu izinikele ekuqandisweni kwezimboni iminyaka eyi-19 futhi inganikeza ama-industrial chiller ezinhlobo ezahlukene zemishini yokushisela we-laser. Ama-recirculating chiller alula ukusetshenziswa, ukulungiswa okuphansi, impilo yesevisi ende, nokuthembeka okungenakuqhathaniswa. Amandla okupholisa asukela ku-0.6KW kuya ku-30KW, okungahlangabezana nezidingo zokupholisa ezivela kubasebenzisi abahlukene. Uma ungaqiniseki ukuthi iyiphi imodi ye-recirculating chiller ongayikhetha, vele usithumelele i-imeyili ku- marketing@teyu.com.cn
