Isizathu sokuqala:Kufuneka sicinge malunga nokuba yingxaki yoyilo lomthengi.Kuyimfuneko ukujonga ukuba kukho imodi yokudibanisa phakathi kwepadi kunye nephepha lobhedu, eliya kukhokelela ekufudumeni okunganeleyo kwepadi.
Isizathu sesibini :Ingaba yingxaki yokusebenza kwabathengi.Ukuba indlela ye-welding ayilunganga, iya kuchaphazela amandla anganeleyo okufudumala, ukushisa kunye nexesha lokudibanisa, okuya kwenza kube nzima ukwenza i-tin.
Isizathu sesithathu : ukugcinwa okungafanelekanga.
① Phantsi kweemeko eziqhelekileyo, umphezulu wokutshiza ngenkcenkce uya kuba ne-oxidized ngokupheleleyo okanye ube mfutshane malunga neveki.
② Inkqubo yonyango ye-OSP ingagcinwa malunga neenyanga ezi-3.
③ Ukugcinwa kwexesha elide kwepleyiti yegolide.
Isizathu sesine: ukuguquguquka.
① Umsebenzi awanelanga ukususa ngokupheleleyo izinto oxidizing zePCB iphediokanye indawo ye-welding ye-SMD.
② Ubungakanani be-solder paste kwi-solder joint ayanelanga, kwaye ipropati yokumanzisa i-flux kwi-solder paste ayilungile.
③ Itoti kwamanye amalungu e-solder ayigcwalanga, kwaye i-flux kunye ne-tin powder ayinakuxutywa ngokupheleleyo phambi kokusetyenziswa.
Isizathu sesihlanu : pcb factory.
Kukho izinto ezinamafutha kwi-pad ezingakhange zisuswe, kwaye indawo ye-pad ayizange ifakwe i-oxidized ngaphambi kokuba ihambe kumzi-mveliso.
Isizathu sesithandathu: i-reflow soldering.
Ixesha elide kakhulu lokufudumala okanye ukushisa okuphezulu kakhulu kukhokelela ekungaphumeleli komsebenzi we-flux.Iqondo lobushushu laliphantsi kakhulu, okanye isantya sasikhawuleza kakhulu, netoti yayinganyibiliki.
Kukho isizathu sokuba i-solder pad yebhodi yesiphaluka ingabi lula ukwenza i-tin.Xa kufumaniseka ukuba akukho lula ukwenza i-tin, kuyimfuneko ukujonga ingxaki kwangethuba.
