Umshini wokuhlola unamathisele we-solder, owaziwa nangokuthi iphrinta ye-stencil noma umshini wokuhlola unamathisele we-solder (SPI), iyithuluzi elisetshenziselwa ukuhlola ikhwalithi nokunemba kokufakwa kwe-solder paste kumabhodi esekethe aphrintiwe (ama-PCB) phakathi nenqubo yokukhiqiza.
Le mishini yenza imisebenzi elandelayo:
Ukuhlolwa kwevolumu yokunamathisela kwe-solder: Umshini ukala futhi uhlola ivolumu yokunamathisela kwe-solder efakwe ku-PCB.Lokhu kuqinisekisa ukuthi inani elilungile lokunamathisela i-solder lisetshenziselwa ukusoda ngendlela efanele futhi kuqeda izinkinga ezifana nokubhola kwe-solder noma ukumbozwa kwe-solder okwanele.
Ukuqinisekiswa kokuqondanisa kokunamathisela kwe-solder: Umshini uqinisekisa ukuqondanisa kwe-solder paste ngokuphathelene namaphedi e-PCB.Ihlola noma yikuphi ukungahambi kahle noma i-offset, iqinisekisa ukuthi i-solder paste ibekwe ngokunembile ezindaweni ezihlosiwe.
Ukutholwa kokulimala: Umshini wokuhlola ukunamathisela i-solder ukhomba noma yimaphi amaphutha afana nokugcotshwa, ukubopha ibhuloho, noma amadiphozithi afakwe ngokungahambi kahle.Ingahlonza izinkinga ezifana nokunamathisela kwe-solder okweqile noma okunganele, ukubekeka okungalingani, noma amaphethini e-solder angaphrintiwe kahle.
Isilinganiso sobude bokunamathisela kwe-solder: Umshini ukala ukuphakama noma ukujiya kwamadiphozithi anamathisele we-solder.Lokhu kusiza ukuqinisekisa ukuvumelana ekubunjweni kwejoyinti le-solder futhi kuvimbela izinkinga ezifana ne-tombstoneing noma i-solder joint voids.
Ukuhlaziywa kwezibalo nokubika: Imishini yokuhlola yokunamathisela kwe-solder ivame ukuhlinzeka ngokuhlaziywa kwezibalo nezici zokubika, okuvumela abakhiqizi ukuthi balandelele futhi bahlaziye ikhwalithi yokunamathisela kwe-solder ngokuhamba kwesikhathi.Le datha isiza ekuthuthukisweni kwenqubo futhi isiza ekuhlangabezaneni namazinga ekhwalithi.
Sekukonke, imishini yokuhlola i-solder paste isiza ukuthuthukisa ukuthembeka kanye nekhwalithi ye-solder ekukhiqizeni i-PCB ngokuqinisekisa isicelo esinembile sokunamathisela i-solder nokuthola noma yiziphi iziphambeko ngaphambi kokucubungula okwengeziwe, njengokuphinda kufakwe i-solder noma i-wave soldering.Le mishini idlala indima ebalulekile ekukhiqizeni isivuno kanye nokunciphisa amathuba ezinkinga ezihlobene ne-solder kuma-elekthronikhi.
