I-Surface Mount Technology (SMT) kunye neSicelo sayo kwiNdawo yoMveliso

Kumashishini anamhlanje avela ngokukhawuleza okwenziwa kwezixhobo zombane, iSurface Mount Technology (SMT) idlala indima ebalulekileyo. Itekhnoloji ye-SMT ibandakanya ukubekwa ngokuthe ngqo kwamacandelo e-elektroniki kwiiBhodi zeSekethe eziShicileleyo (iiPCB) ezingakhange ziqhubele nje ukwenziwa kweminiaturization, ukukhaphukhaphu, kunye nokusebenza okuphuculweyo kweemveliso zombane, kodwa kuphuculwe ngokubonakalayo ukuthembeka kwemveliso kunye nempumelelo yokwenziwa ngelixa kuncitshiswa iindleko zemveliso.

Inkqubo eSisiseko ye-SMT yokuNqanyiswa koMphezulu

Inkqubo yokunyuswa komphezulu we-SMT ichanekile kwaye iyasebenza, iquka amanyathelo abalulekileyo aliqela:

Ushicilelo lwe-Solder Paste: Ukusebenzisa i-solder pads kwiiphedi ezithile kwi-PCB ukulungiselela ukunyuswa kwendawo echanekileyo.

Ukunyuka kwenxalenye: Ukusebenzisa isixokelelwano sokuxhoma somgangatho ophezulu wokuchaneka ukubeka izinto ze-elektroniki kwiipads ezifakwe kwi-solder.

I-Soldering kwakhona: Ukunyibilikisa intlama ye-solder kwi-oveni yokuqukuqela kwakhona ngokujikeleza komoya oshushu ukuze ubophe ngokuqinileyo amacandelo e-elektroniki kwi-PCB.

Uhlolo oluzenzekelayo lwaMacho (AOI): Oomatshini be-AOI bahlola umgangatho we-PCB ethengisiweyo ukuqinisekisa ukuba akukho ziphene ezifana namalungu angalunganga, iindawo ezingekhoyo, okanye umva.

Ukuhlolwa kweX-Ray: Ukusebenzisa izixhobo zokuhlola i-X-reyi kulawulo lobulunga obunzulu obufihliweyo, njengabo bakwi-Ball Grid Array (BGA) ukupakishwa.

IiMfuno zoLawulo loBuqondo kwiNdawo zeMveliso

Imigca yemveliso ye-SMT inemigangatho engqongqo yobushushu kunye nokufuma kwindawo yokusebenza. Ulawulo lobushushu lubalulekile ukugcina uzinzo lwezixhobo kunye nomgangatho wokuthengisela, ngakumbi kwiindawo ezinobushushu obuphezulu.:

Izixhobo zokulawula ubushushu: Izixhobo ze-SMT, ngokukodwa iinkqubo zokunyuka kwendawo kunye nee-ovens eziphinda zigqithise, zenza ukushisa okukhulu ngexesha lokusebenza. Izixhobo zokupholisa ezichanekileyo zithintela ukushisa ngokugqithiseleyo kwaye ziqinisekisa ukusebenza okuqhubekayo okuzinzileyo.

IiMfuno zeNkqubo eyodwa: Izixhobo zokupholisa  inceda ukugcina imo efunekayo yobushushu obuphantsi kumacandelo anovakalelo lobushushu okanye iindlela ezithile zokuthambisa.

Izixhobo zokupholisa ezifana izixhobo zokupholisa amanzi kwimizi-mveliso  kubalulekile ukugcina ukusebenza kakuhle kwemigca yemveliso, ukuthintela iziphene zokuthengisela okanye ukuthotywa kokusebenza okubangelwa ngamaqondo obushushu agqithisileyo.

Izinto eziluncedo zokusiNgqongileyo zokuFaka umphezulu we-SMT

Itekhnoloji ye-SMT ivelisa inkunkuma encinci ngexesha lenkqubo yokwenziwa kwemveliso, ekulula ukuyihlaziya nokuyilahla. Oku kwenza ukuba ubuchwephesha bokusebenza kwe-SMT buvumelane nokusingqongileyo kwaye busebenzise amandla. Kugxininiso lwanamhlanje lwehlabathi kukhuselo lokusingqongileyo kunye nophuhliso oluzinzileyo, ithekhnoloji ye-SMT ngokuthe ngcembe iba yinkqubo ekhethwayo kushishino lokwenziwa kombane.

Itekhnoloji ye-SMT yokuphakama komphezulu ingamandla aqhuba ukuqhubela phambili koshishino lokwenziwa kombane. Ayiphuculi kuphela ukusebenza kunye nokuphumelela kwemveliso yeemveliso ze-elektroniki kodwa inegalelo ekunciphiseni iindleko zokwenziwa kunye nokunciphisa impembelelo yokusingqongileyo. Ngenkqubela phambili yobuchwepheshe eqhubekayo, ukunyuswa komphezulu we-SMT kuya kuqhubeka ukudlala indima ephambili kwikamva lokwenziwa kombane.
