1. Ngaphambi PCB ifakwereflow oveni-welding, qinisekisa ukuthi ama-pads ezingxenye namabhodi wesekethe ayashisela (ahlanzekile, akukho ukungcola, akukho oxidation, njll.).
2. Gqoka ama-antistatic caps lapho ucutshungulwa futhi ushiswa.
3. Gqoka amagilavu e-ESD ngesikhathi sokushisela ukuze ugweme ukushaqeka kukagesi.
4. Uma i-ayina kagesi idinga ukusetshenziswa nsuku zonke, kufanele ilawulwe ngeswishi yesokhethi yamandla, noma ifakwe iswishi yamandla entanjeni yamandla ensimbi kagesi, ukuze kugwenywe ukuxhuma njalo nokukhipha ipulaki okuholela ekubeni ipulaki exege futhi ibe buthaka. othintana naye.
5. Ikhanda lensimbi kagesi akufanele licwiliswe ekugubheni isikhathi eside, futhi eminye imikhiqizo yezimboni yamakhemikhali egqwala kakhulu akufanele isetshenziswe njenge-flux.
6. Insimbi kagesi enamandla amancane ayikwazi ukufinyelela ukushisa ngezinye izikhathi, futhi isikhathi se-welding side kakhulu, okulula ukulimaza izingxenye ze-elektroniki.Ungakhetha insimbi kagesi ngamandla amancane, futhi ukushisa kwanele, okunganciphisa isikhathi sokushisela.
7. I-IC kufanele yenziwe ekugcineni kuyo yonke inqubo yokushisela, futhi i-welding kufanele igqoke isongo eliphikisana ne-static, insimbi yokunamathisela kagesi kufanele isekelwe ngokuthembekile.
8. Ngemuva kwe-welding, sula i-flux esele ebhodini lesifunda ngotshwala ukuze ugweme ukuthinta ukusebenza okuvamile kwesifunda.
9. Ngemva kokushisela, cisha futhi uhlanze itafula.
10. Faka esikhundleni ikhebula lamandla ngemva kokuba insimbi yokunamathisela kagesi isetshenziswa njalo isikhathi esithile ukuvimbela impande noma ukuphuka kwangaphakathi kwekhebula lamandla.
I-Zhejiang NeoDen Technology Co., Ltd. ibikhiqiza futhi ithumela kwamanye amazwe amancane ahlukahlukeneumshini wokukhetha nokubekakusukela ngo-2010. Sisebenzisa i-R&D yethu ecebile enesipiliyoni, ukukhiqizwa okuqeqeshwe kahle, i-NeoDen izuza idumela elihle kumakhasimende omhlaba wonke.
Njengoba kukhona emhlabeni wonke emazweni angaphezu kwe-130, ukusebenza okuhle kakhulu, ukunemba okuphezulu nokuthembeka kwemishini ye-NeoDen PNP kuyenza ifanelekele i-R&D, i-prototyping yobungcweti kanye nokukhiqizwa kwenqwaba encane kuya kwemaphakathi.Sihlinzeka ngesixazululo sochwepheshe semishini yokumisa eyodwa ye-SMT.
