- Ukuze uvimbele ukuwa ngesikhathi se-soldering ye-module, ungayithengisi ngemuva kwebhodi ngesikhathi sokuklama, okungukuthi, kungcono ukuthi ungadluli umjikelezo we-soldering kabili.
- Ukusethwa kwezinga lokushisa lokunamathisela kuncike ezintweni eziningi zefekthri, njengohlobo lwebhodi, uhlobo lokunamathisela i-solder, ukujiya kokunamathisela kwe-solder, njll. Sicela futhi ubhekisele kumazinga e-IPC afanelekile kanye nezinkomba zokunamathisela kwe-solder.
- Njengoba izinga lokushisa le-lead soldering liphansi kakhulu, uma usebenzisa le ndlela, sicela unike kuqala ezinye izingxenye ebhodini.
- Ukuvulwa kwe-stencil kudinga ukuhlangabezana nesidingo sakho sokuklama futhi kuhambisane nezindinganiso zokuhlola. Ubukhulu be-stencil bunconywa ukuthi bube ngu-0.15 mm.
Ukupakisha
Incazelo Yelebula
Ukupakishwa Komkhiqizo
Imojula ye-UM960L isebenzisa itheyiphu yenkampani yenethiwekhi ne-reel (efanele amadivaysi okukhweza angaphezulu), ahlanganiswe ngezikhwama ze-aluminiyamu ezivalwe nge-vacuum ze-antistatic, ezine-desiccant ngaphakathi ukuvimbela umswakama. Uma usebenzisa inqubo ye-reflow soldering kumamojula e-solder, sicela uhambisane ngokuqinile nezinga le-IPC ukuze ulawule umswakama. Njengoba izinto zokupakisha ezifana ne-tape yenethiwekhi zingamelana kuphela nokushisa kwe-55 ° C, amamojula azosuswa ephaketheni ngesikhathi sokubhaka.
Ithebula 5-1 Incazelo Yephakheji
| Into | Incazelo |
| Imojuli Inombolo | 500 izingcezu / esondweni |
| I-reel Usayizi | Ithreyi: 13″ Ububanzi bangaphandle: 330 mm Ububanzi bangaphakathi: 100 mm Ububanzi: 24 mm Ubukhulu: 2.0 mm |
| Inkampani yenethiwekhi Itheyiphu | Isikhala phakathi (ibanga eliphakathi nendawo): 20 mm |
I-UM960L ilinganiselwe kuzinga lesi-3 le-MSL. Bheka kumazinga afanelekile e-IPC/JEDEC J-STD-033 ngephakheji kanye nezidingo zokusebenza.
Ungakwazi ukufinyelela ku- webindawo www.jedec.org ukuze uthole ulwazi olwengeziwe.
Isikhathi seshelufu semojula ye-UM960L epakishwe ezikhwameni ze-aluminiyamu evalwe nge-vacuum evalwe nge-antistatic unyaka owodwa.
