Tinning feem ntau yog ua los xyuas kom meej tias cov hlau yuav tsum tau soldered muaj ib tug uniform thiab yooj yim solderable nto. Tinning
ntawm stranded hlau muaj qhov txiaj ntsig ntxiv ntawm kev sib txuas ntawm tus kheej cov hlau strands ua ke, yog li tso cai rau cov hlau tsim.
mus rau terminals lossis cov ntsiab lus txuas yam tsis muaj kev sib cais ntawm tus kheej strands.
Lus Cim: Cov hlau uas xav tau kev ruaj ntseg hauv cov hlua khi lossis cov hlua khi yuav tsis raug tinned.
Rau Chav Kawm 2 thiab 3:
• Ib feem ntawm cov hlau uas yuav tau soldered yuav tsum tau tinned ua ntej mounting.
• Lub solder yuav tsum ntub cov tinned feem ntawm cov hlau thiab nkag mus rau hauv cov hlua sab hauv ntawm cov hlua khi.
• Txwv tsis pub siv cov hlau nplaum thaum lub sij hawm soldering ntawm cov hlau yog tso cai ntev li ntev raws li lub solder tsis txuas mus rau ib feem ntawm cov hlau uas
yuav tsum nyob twj ywm hloov tau.
Lub tinning yuav tsum tawm ib tug du txheej ntawm solder, thiab cov qauv ntawm cov strands yuav tsum pom.
Txaus - Chav 1,2,3
• Hlau yog coated uniformly nrog ib tug zoo solder tsho tiv no.
• Stranded hlau yog uniformly coated nrog ib tug nyias txheej ntawm solder
nrog tus kheej strands ntawm cov hlau yooj yim pom.
• Untinned ntev ntawm strands los ntawm qhov kawg ntawm rwb thaiv tsev tsis yog
ntau dua ib txoj kab uas hla (D).
Cov txheej txheem qhia - Chav 2,3
• Strands tsis pom tab sis tsis cuam tshuam nrog daim ntawv, haum,
muaj nuj nqi lossis kev ntseeg siab.
Tsis Zoo - Chav Kawm 2,3
• Stranded hlau tsis tinned ua ntej sib dhos.
Tsis Zoo - Chav Kawm 1,2,3
• Hlau muaj pinholes, voids los yog qhov chaw uas solder tsis wetted
rau kab.
Tsis Zoo - Chav Kawm 3
• Ntev ntawm untinned strands los ntawm qhov kawg ntawm rwb thaiv tsev yog ntau dua
tshaj ib txoj kab uas hla (D).
