Okokuqala, kufuneka sazi ukuba kumgca wemveliso we-SMT, iumatshini wokushicilela we-solder ozenzekelayoifuna ukuchaneka okuphezulu kakhulu, i-solder paste i-demoulding effect ilungile, inkqubo yoshicilelo izinzile, ilungele ushicilelo lwezahlulo ezixineneyo.Ukungalungi kukuba iindleko zokulondolozwa ziphezulu kwaye inqanaba lolwazi lwabaqhubi liphezulu.
1. Xa i-scraper yeUmatshini wokushicilela we-SMTihamba phambili ngesantya esithile kunye ne-Angle, iya kuvelisa uxinzelelo oluthile kwi-solder paste, eya kutyhala i-solder paste ukuze iqengqeleke phambi kwe-scraper kwaye ivelise uxinzelelo olufunekayo ukutofa i-solder paste kwi-mesh okanye umngxuma ovuzayo;
2. Amandla ancamathelayo ancamathelayo entlama ye-solder abangela ukucheba kwentlama ye-solder ekudibaneni kwe-scraper kunye ne-net plateUmshicileli westencil we-SMT.Amandla okucheba anciphisa i-viscosity ye-solder paste, ehambelana nenaliti egudileyo ye-solder paste ekuvuleni okanye ukuvuza kwetemplate.Kukho ubudlelwane obuthintelweyo phakathi kwesantya seblade, uxinzelelo lweblade, iAngle yeblade enetemplate, kunye nokuncamathisela i-viscosity.Ngoko ke, umgangatho wokushicilela we-solder paste unokuqinisekiswa kuphela xa ezi parameters zilawulwa ngokufanelekileyo.
3. Xa i-blade ihamba phambili ngesantya esithile kunye ne-Angle, i-butt paste ivelisa uxinzelelo oluthile, ikhuthaze i-solder paste phambi kwe-scraper roller, iya kuvelisa i-solder paste kwi-mesh yokuvula (itemplate) uxinzelelo olufunekayo, i-solder paste i-viscosity friction ukwenza i-solder. ncamathelisa kwi-scraper kunye ne-shear transfer shear open (itemplate), i-shear force yenza i-solder paste viscosity iyancipha, ngaloo ndlela iphumelele kwi-mesh;Xa i-scraper ishiya ukuvulwa kwethemplate, i-viscosity yokunamathisela ibuyela ngokukhawuleza kwisimo sokuqala.
Xa sisebenza, kuphela xa i-solder paste iqengqeleka phambi kwe-scraper, inokuvelisa uxinzelelo lokufaka i-solder paste kwindawo yokuvula;Ubungakanani be-solder paste imiselwa yinqanaba le-solder paste egcwalisa ukuvulwa kwethemplethi, kwaye ingqibelelo ye-demoulding imisela ukuvuza kwe-solder paste kunye nokuthembeka kwepateni yokucola i-solder.
