Umshini Werobhothi Wohlobo Lwesitezi GR-F-LS441
Kuyini i-laser soldering?
Sebenzisa i-laser ukugcwalisa nokuncibilikisa i-tin ukuze uzuze ukuxhumana, ukuqhutshwa nokuqiniswa.
I-Laser iyindlela yokucubungula engathinteki. Uma kuqhathaniswa nendlela yendabuko, inezinzuzo ezingenakuqhathaniswa, umphumela omuhle wokugxila, ukugxila kokushisa, kanye nendawo encane yomthelela oshisayo ezungeze i-solder joint, okulungele ukuvimbela ukuguquguquka nokulimala kwesakhiwo esizungeze ucezu lokusebenza.
I-laser soldering ihlanganisa ukunamathisela i-laser soldering, i-laser soldering ne-ball laser soldering. I-solder paste, i-tin wire kanye nebhola le-solder kuvame ukusetshenziswa njengezinto zokugcwalisa kunqubo ye-laser soldering.
Izici
Tin Ball Laser Welding
Ngemuva kokushiswa nokuncibilika nge-laser, amabhola e-solder akhishwa ku-nozzle ekhethekile futhi amboze ngokuqondile ama-pads. Akukho flux eyengeziwe noma amanye amathuluzi adingekayo. Ifaneleka kakhulu ukucubungula okudinga izinga lokushisa noma indawo ye-welding yebhodi elithambile. Phakathi nayo yonke inqubo, amalunga e-solder kanye nomzimba wokushisela awaxhumani, okuxazulula usongo lwe-electrostatic olubangelwa ukuthintana ngesikhathi senqubo yokushisela.
Uma kuqhathaniswa nobuchwepheshe bendabuko, i-laser solder ball welding inezinzuzo ezilandelayo:
- Ukunemba kokucubungula kwe-laser kuphezulu, indawo ye-laser incane, uhlelo lungakwazi ukulawula isikhathi sokucubungula, futhi ukunemba kuphakeme kunendlela yenqubo yendabuko. Ifanele ukuthelwa kwezingxenye ezincane zokunemba kanye nezindawo lapho izingxenye ze-solder zizwela kakhulu izinga lokushisa
- Ukucubungula okungaxhunywanga, akukho ugesi omile obangelwa ukushisela, ongacutshungulwa ngezindlela ezivamile okungelula ukushiselwa ngesandla
- I-laser encane ingena esikhundleni sethiphu yensimbi ehlanganisiwe, futhi kulula ukuyicubungula uma kukhona ezinye izinto eziphazamisayo ebusweni bengxenye ecutshunguliwe.
- Ukushisa kwendawo, indawo encane ethintekile ukushisa; akukho usongo lwe-electrostatic
- I-Laser iyindlela yokucubungula ehlanzekile, ukulungiswa okulula, ukusebenza okulula, nokuzinza okuhle kokusebenza okuphindaphindiwe
- Ijubane lokushisa liyashesha, futhi ukuma kunembile, okungaqedwa ngemizuzwana engu-0.2
- Ububanzi bebhola likathayela bungaba buncane obungama-250μm, bufanelekele ukushisela okunembayo okuphezulu
- Izinga lokukhiqiza le-solder liphakeme kunalelo lemishini evamile yokuhlanganisa okuzenzakalelayo
- Ngesistimu yokumisa ebonakalayo, ilungele ukukhiqizwa komugqa wokuhlanganisa
I-Wire Laser Soldering
I-tin wire laser welding ifanelekela iphinikhodi evamile ye-PCB/FPC, ucingo lwephedi neminye imikhiqizo enosayizi omkhulu wephedi nesakhiwo esivulekile. Kuyinselele ukubona ukushiselwa kwe-laser kocingo oluncane lwamaphoyinti athile, okunzima ukukufeza ngomshini wokuphakela ngocingo futhi kulula ukuwujika.
Namathisela Laser Soldering
Inqubo yokunamathisela ye-laser yokunamathisela ilungele iphinikhodi evamile ye-PCB / FPC, umugqa wephedi nezinye izinhlobo zemikhiqizo.
Indlela yokucubungula ye-solder unamathisele i-laser welding ingacatshangelwa uma isidingo sokunemba siphezulu futhi indlela yezandla iyinselele ukuyifinyelela.
