【Solderability test (khawm hloov】
Sab saum toj ntawm lub davhlau ya nyob twg yog nkag mus rau hauv lub pas dej tin welding 1㎜ sib sib zog nqus, thiab qhov kub yog 230 ± 5 ℃, lub sijhawm yog 3 ± 0.5 vib nas this.
Ua tib zoo mloog rau:
(1) Lub sijhawm vuam yuav tsum tsis txhob siab tshaj 3 vib nas this.
(2) Qhov chaw vuam yuav tsum yog ntau tshaj 75%.
【Welding resistance test】
Qhov kub ntawm qhov cub vuam yog tswj ntawm 260 ± 5 ℃, thiab lub sijhawm vuam yog 3 ± 0.5 vib nas this.Qhov kub ntawm cov phaj vuam yog 320 ± 5 ℃, thiab lub sijhawm vuam yog 3 ± 0.5 vib nas this.
Nco tseg: yuav tsum txaus siab rau lub cev tsis muaj deformation, txhua yam thiab hluav taws xob lub zog.
【Kev xeem lub neej】
Tsis muaj kev thauj khoom: Tus neeg teb xov tooj ua qhov ntsuas tsis muaj load ntawm 100,000 cycles ntawm tus nqi ntawm 60 cycles ib feeb.
Ua tib zoo mloog rau:
(1) Kev tiv thaiv kov tsis tuaj yeem tshaj 200m ω
(2) Lwm yam, txaus siab rau kev siv tshuab thiab hluav taws xob.
【Heat resistance test】
Tom qab 96 teev ntawm kev ntsuam xyuas ntawm 85 ± 2 ℃, nws tau muab tso rau hauv chav sov li 1 teev.
Nco tseg: tsis muaj qhov rov qab mus tas li, txaus siab rau kev siv tshuab thiab hluav taws xob.
【Cold resistance test】
Cov qauv tau muab tso rau hauv ib puag ncig ntawm 90 ~ 96 degrees txheeb ze av ntawm 40 ± 2 ℃ rau 96 teev, thiab tom qab ntawd muab tso rau hauv ib puag ncig ib puag ncig rau 1 teev ua ntej kuaj.
Daim ntawv ceeb toom: tsis muaj qhov txawv txav ntawm qhov tsos, txaus siab rau cov khoom siv hluav taws xob thiab hluav taws xob.
【Wetting test】
Muab tso rau 40 ntxiv lossis rho tawm 2 ℃.Cov av noo ntawm 90 ~ 96 degrees hauv ib puag ncig tom qab 96 teev, thiab tom qab ntawd muab cov qauv tso rau hauv ib puag ncig ib puag ncig rau 1 teev tom qab kuaj.
Daim ntawv ceeb toom: tsis muaj qhov txawv txav ntawm qhov tsos, txaus siab rau cov khoom siv hluav taws xob thiab hluav taws xob.
Tom qab cov kev ntsuam xyuas no, peb tuaj yeem tau txais lub neej ua haujlwm ntawm lub khawm hloov, qhov zoo ntawm cov khoom tiav, thiab tom qab ntawd cia peb siv lub khawm hloov ntau dua.
