Ngamanye amaxesha kuya kubakho isenzeko sokuqhubekeka esingalunganga kwinkqubo yeUmatshini we-SMT, i-tin bead yenye yazo, ukusombulula ingxaki, kufuneka siqale sazi unobangela wengxaki.I-solder beading ikwi-solder paste slump okanye kwinkqubo yokucinezela ngaphandle kwe-pad.Ngexeshareflow oveni-soldering, i-solder paste ibekwe yodwa kwidiphozithi engundoqo kwaye idityaniswe kunye ne-solder intlama engaphezulu ukusuka kwezinye iipads, nokuba zivela kwicala lomzimba wecandelo ukwenza amaso amakhulu, okanye ukuhlala ngaphantsi kwecandelo.Ukupheliswa kwamaso e-tin kangangoko kunokwenzeka ngokususwa ngokuthe ngqo kwendlela, kwinkqubo yokuvelisa ingqalelo, kunokuphetshwa.Oku kulandelayo kukuhlalutya ukuba zeziphi iimeko eziza kuvelisa i-solder beading:
I. Steel Mesh
1. Ukuvulwa kwe-mesh yensimbi ngokuthe ngqo ngokuhambelana nobukhulu bokuvuleka kwe-pad kuya kukhokelela kwi-tin bead phenomenon kwinkqubo yokucubungula i-patch.
2. Ukuba ubukhulu bomnatha wensimbi bukhulu kakhulu, kunokwenzeka ukuba kubangele ukuwa kwe-solder paste, eya kuvelisa ubuhlalu be-tin.
3. Ukuba uxinzelelo lwekhetha kwaye ubeke umatshiniiphezulu kakhulu, intlama ye-solder iya kugqithiselwa ngokulula kumaleko okumelana ne-solder ngezantsi kwecandelo, kwaye i-solder paste iya kunyibilika kwaye ijikeleze icandelo ukwenza amaso e-solder ngexesha le-oveni yokuququda.
II.Intlama ye-solder
1. I-solder paste ngaphandle kokulungiswa kobushushu kwinqanaba lokufudumeza kuya kutshiza isenzeko ukuvelisa amaso etoti.
2. Incinci incinci ye-particle ye-powder yensimbi kwi-solder paste, inkulu indawo yonke yendawo ye-solder paste, ekhokelela kwiqondo eliphezulu le-oxidation yomgubo ococekileyo, ngoko ke i-phenomenon ye-solder beads iqiniswa.
3. Ukuphakama kweqondo le-oxidation ye-powder yensimbi kwi-solder paste, i-powder yensimbi enkulu yokumelana nokuxhatshazwa ngexesha le-welding, i-solder paste kunye ne-pad kunye namacandelo e-SMT akulula ukungena, okubangelwa ukunciphisa ukuthengiswa.
4. Umthamo we-flux kunye nenani le-flux esebenzayo ininzi kakhulu, eya kubangela ukuwa kwendawo ye-solder paste kunye ne-tin beads.Xa umsebenzi we-flux ungonelanga, inxalenye ye-oxidized ayikwazi ukususwa ngokupheleleyo, eya kukhokelela kwi-tin beads kwi-processing ye-patch processing factory.
5. Isiqulatho sesinyithi kwiprosesa eyiyo yokuncamathisela i-tin ngokuqhelekileyo yi-88% ukuya kwi-92% yomxholo wesinyithi kunye nomlinganiselo wobunzima, umlinganiselo wevolumu malunga ne-50%, ukwandisa umxholo wesinyithi unokwenza ilungiselelo lomgubo wesinyithi lisondele ngakumbi, ukuze kulula ukudibanisa xa kunyibilika.
