Umatshini wokuvavanya i-solder paste, owaziwa ngokuba ngumshicileli we-stencil okanye i-solder paste inspection (SPI) umatshini, sisixhobo esisetyenziselwa ukuvavanya umgangatho kunye nokuchaneka kwe-solder paste deposition kwiibhodi zesekethe eziprintiweyo (PCBs) ngexesha lenkqubo yokuvelisa.
Aba matshini benza le misebenzi ilandelayo:
Ukuhlolwa komthamo we-solder paste: Imilinganiselo yomatshini kwaye ihlola umthamo we-solder paste efakwe kwi-PCB.Oku kuqinisekisa ukuba isixa esichanekileyo sokuncamatheliswa kwe-solder sisetyenziselwa ukubethelwa ngokufanelekileyo kwaye kuphelisa imiba efana nebhola ye-solder okanye i-solder coverage eyaneleyo.
Ukuqinisekiswa kokulungelelaniswa kwe-solder paste: Umatshini uqinisekisa ukulungelelaniswa kwe-solder paste ngokubhekiselele kwi-PCB pads.Ihlola nayiphi na i-misalignment okanye i-offset, iqinisekisa ukuba i-solder paste ibekwe ngokuchanekileyo kwiindawo ezijoliswe kuzo.
Ukufunyanwa kweziphene: Umatshini wokuvavanya intlama ye-solder uchonga naziphi na iziphene ezifana nokuthanjiswa, ukubopha ibhulorho, okanye iidiphozithi ze-solder ezingemi kakuhle.Iyakwazi ukubona imiba efana nokugqithisa okanye ukungonelanga kwe-solder paste, ukudityaniswa kokungalingani, okanye iipateni ze-solder ezingaprintwanga kakuhle.
Umlinganiselo we-solder paste ukuphakama: Umatshini ulinganisa ubude okanye ubukhulu beediphozithi ze-solder paste.Oku kunceda ukuqinisekisa ukuhambelana kwi-solder joint formation kunye nokuthintela imiba efana ne-tombstoneing okanye i-solder joint voids.
Uhlalutyo lwamanani kunye nokunika ingxelo: Oomatshini bokuvavanya i-solder paste bahlala bebonelela ngohlalutyo lwamanani kunye neempawu zokunika ingxelo, ukuvumela abavelisi ukuba balandele kwaye bahlalutye umgangatho we-solder paste deposition ngokuhamba kwexesha.Le datha inceda ekuphuculeni inkqubo kwaye inceda ukuhlangabezana nemigangatho yomgangatho.
Ngokubanzi, oomatshini bokuvavanya intlama ye-solder banceda ukuphucula ukuthembeka kunye nomgangatho wokuthengisa kwi-PCB yokuvelisa ngokuqinisekisa isicelo esichanekileyo sokunamathisela i-solder kunye nokufumanisa naziphi na iziphene ngaphambi kokuqhubekela phambili, okufana ne-reflow soldering okanye i-wave soldering.Aba matshini badlala indima ebalulekileyo ekuveliseni isivuno kunye nokunciphisa amathuba emicimbi enxulumene ne-solder kwiindibano ze-elektroniki.
