Ukudibanisa
Uqhagamshelwano lwebhulorho yenye yeziphene eziqhelekileyo kwimveliso ye-SMT.Iya kubangela isiphaluka esifutshane phakathi kwamacandelo, kwaye kufuneka ilungiswe xa idibana noqhagamshelo lwebhulorho.Kukho izizathu ezininzi zoqhagamshelwano lwebhulorho
1) Iingxaki zomgangatho we-solder paste
① Umxholo wesinyithi kwi-solder paste iphezulu, ngakumbi ukuba ixesha lokushicilela lide kakhulu, kulula ukunyusa umxholo wesinyithi, okukhokelela kwi-IC pin bridging;
② I-solder paste ine-viscosity ephantsi kwaye iphuphuma ngaphandle kwe-solder pad emva kokushisa kwangaphambili;
③ Ithontsi ye-solder paste tower ayilunganga, kwaye iphuphuma ngaphandle kwe-solder pad emva kokufudumeza kwangaphambili;
Isisombululo: Lungisa umlinganiselo we-solder paste okanye sebenzisa umgangatho ophezulu we-solder paste.
2) Inkqubo yoshicilelo
① Ukuchaneka okuphindaphindiweyo komatshini wokushicilela akubi, kwaye ukulungelelaniswa akukho (ukulungelelaniswa kwepleyiti yentsimbi akulungile, ukulungelelaniswa kwePCB akulungile), okubangela ukuba i-solder paste iprintwe ngaphandle kwepadi, ngakumbi i-pitch ye-QFP pad;
② Ubungakanani kunye nobukhulu befestile yetemplate ayenzelwanga ngokuchanekileyo, kwaye i-Sn Pb ye-alloy coating yoyilo lwephedi ye-PCB ayifani, nto leyo ekhokelela kwi-solder paste.
Isisombululo: Lungisa umshicileli kwaye uphucule i-PCB pad coating.
3) Isizathu esiqhelekileyo kwimveliso yokuba i-solder paste ihamba ngokupheleleyo emva kokuba icinezelwe ngenxa yoxinzelelo olugqithisileyo.Ukongeza, ukuba ukuchaneka kokubeka akwanelanga, amacandelo aya kutshintsha kwaye izikhonkwane ze-IC ziya kutshintsha.
I-4) Isantya sokufudumala kwesithando somlilo sikhawuleza kakhulu, i-solvent kwi-solder paste ayinaso ixesha lokuguquka.
Isisombululo: Lungisa ubude be-Z axis ye-SMT kunye nesantya sokufudumeza kwesithando somlilo.
Inqaku kunye nemifanekiso evela kwi-intanethi, ukuba kukho naluphi na ulwaphulo pls kuqala uqhagamshelane nathi ukuze ucime.
