Uma jikeleleUmshini we-X-rayInkinga yokushisela i-virtual ayikwazi ukuhlolwa, ungasebenzisa uyinki obomvu nesigaba ukuthola inkinga?Kodwa uma ukufudumeza nomareflow ovenukushisela, ukucutshungulwa kwe-PCBA ngemuva kokuhlolwa futhi kuphumelele, bese wenza ukuhlolwa kwe-inki ebomvu nocezu kuzoba usizo?Uma ikhasimende licela ukuthatha ibhodi elihle ukuze likwenze futhi, singakwazi yini ukubona ukuthi inkinga yenqubo?
I-Q1: Ngokujwayelekile, uma ukushisela okungamanga kwezingxenye ezingezona ze-BGA kungabonwa ngeso lenyama, ngoba i-solder ye-welding yamanga izokwakha isici esicacile se-welding, esingabonakala kalula ngaphansi kwesimo esivamile sokuthengisa.
Kusukela encazelweni yombuzo, singaqagela ukuthi obuzayo bekufanele ahlangabezane nekhwalithi engajwayelekile ye-BGA noma ingxenye ye-IC yokushisela.I-3DX-Ray scanning imaging ingasetshenziswa ukuthola ukushisela okungamanga ekucubunguleni kwe-SMT SMT.Lokhu futhi kuyindlela eyinhloko esebenzayo kanye nendlela yokuhlolwa kokushisela kwezingxenye ze-BGA/IC, okungangabazeki okuqinisekiswa iningi labakhiqizi be-PCBA.
Kodwa uma ibhola ngokwalo liphukile noma izinga lebhola lingajwayelekile, kungase kudingeke ukuthi lihlaziywe kusetshenziswa inki ebomvu kanye nokuhlolwa kocezu, ngoba lokhu kuphazamiseka akutholwa nge-X-ray.
I-Q2: Uma inkinga ye-BGA ingaqinisekisiwe, i-solder paste i-reflow oven welding futhi, engase ivale iphuzu langempela lenkinga.Ngaphezu kwalokho, enye inkinga ukuthi umthombo wamaphuzu wekhwalithi uzobhujiswa, ngakho-ke akuqinisekisiwe ukuthi singabheka amaphuzu amabi wangempela.
Ukwehluleka kwe-BGA kufanele kuqale kuqede izinkinga zekhwalithi yebhola le-tin ngokwalo, futhi konke okunye kufanele kuqinisekiswe njengezinkinga ze-welding interface noma ukulungiswa kwezinga lokushisa.Izixhumanisi ezihlukene zizoveza amaphuzu ahlukene angavamile.Futhi eziningi ezimbi BGA Welding akuyona inkinga inqubo.
Uma ngempela sifuna ukuhlaziya, kuphakanyiswa ukuthi kukhishwe ucezu lwemikhiqizo enesici ukuze sibonwe yonke indawo, siqinisekise ngekhwalithi edidayo yesixhumanisi ngasinye, ukufakazela ukuthi ingabe sibhekana nalolu hlobo lwesici ngempela, bese sikuxazulula ngokufanele.
I-Zhejiang NeoDen Technology Co., LTD., eyasungulwa ngo-2010, ingumkhiqizi ochwepheshe okhethekile emshinini wokukhetha nendawo we-SMT, ihhavini eligeleza kabusha, umshini wokuphrinta we-stencil, ulayini wokukhiqiza we-SMT neminye Imikhiqizo ye-SMT.Onjiniyela abanekhono nabaqeqeshiwe besiNgisi nonjiniyela benkonzo, ukuze baqinisekise impendulo esheshayo phakathi kwamahora ayi-8, isixazululo sihlinzeka kungakapheli amahora angama-24.Eyingqayizivele phakathi kwabo bonke abakhiqizi baseShayina ababhalise futhi bagunyaza i-CE nge-TUV NORD.
