IPC cov txheej txheem rau Flux residue nyob rau hauv davhlau ya nyob
Soldering yog cov txheej txheem ntau heev hauv xaim ua hlau ntaus, nws yog ib txoj kev tseem ceeb los txuas cov xaim thiab cov chaw nyob, thiab flux residue yog ib qho muaj rau soldering. Kev ntxuav tu tom qab soldering yog tus txheej txheem kom paub tseeb tias solding zoo yog qhov zoo thiab nrog kev zoo nkauj. Yog li peb ib txwm ua raws li IPc--620 los tshuaj xyuas cov khoom seem flux.
Flux residue tej zaum yuav muaj tam sim no yog tias nws tsis muaj kev txaus siab huv uas tsis yog npaj kom huv. (Tsis muaj duab)
Phiaj - chav kawm 1,2,3
• Tsis pom muaj qhov tshwm sim pom tau.
Txais - Chav Kawm 1
Qhov taw qhia kev ua tiav - Chav Kawm 2,3
• Flux residue tsis inhibit pom kev soj ntsuam.
• Flux seem tsis aribit nkag mus kuaj cov ntsiab lus ntawm lub rooj sib txoos.

• Fluc seem ntawm, ib ncig, lossis ntaus pob ntawm cov tsis muaj tus saib xyuas.
• Flux residue inhibits pom kev kuaj xyuas.
• Flux residue inhibits nkag mus kuaj cov ntsiab lus ntawm lub rooj sib txoos.
Kev Txhim Kho - Chav Kawm 1,2,3
• ntub, ntub dej, los yog cov khoom seem tsis sib xws uas yuav kis tau rau lwm qhov chaw.
• Tsis muaj cov kab mob uas muaj pa hluav taws kub uas tsis tshua muaj kev sib txuas hluav taws xob.

Phiaj - chav kawm 1,2,3
• Nws muaj tshuaj rwb thaiv tsev (c) ntawm ib lub cheeb (d)
Nruab nrab ntawm lub rwb thaiv tsev thiab sab saum toj ntawm cov yas fillet.
Txais - Chav Kawm 1,2,3
• Diam tawv rwb thaiv tsev yog ob lub xov hlau (d) lossis tsawg dua nrog rau kev thaiv kev lossis 1.5 hli [{2} Nyob rau hauv] (saib txhua qhov twg ntau dua).
• rwb thaiv tsev cantwb tsis tso cai rau luv luv rau cov uas nyob ib puag ncig.
• rwb thaiv tsev clearance yog ze xoom.
