Cov kev xav tau rau kev xeem ib puag ncig
Nyob rau hauv ib txwm muaj teeb pom kev zoo, muab cov khoom tso rau ntawm qhov chaw ua haujlwm, 30CM deb, thiab saib cov khoom ntawm lub kaum sab xis 45 degree.
Ntim cov qauv kuaj xyuas
Txhua lub thawv ntim khoom thiab lub thawv sab hauv yuav tsum tau cim nrog cov khoom siv lub npe, cov lus qhia, cov khoom siv naj npawb, kom muaj nuj nqis, thiab cov cim tiv thaiv ib puag ncig. Lub ntim yuav tsum tsis txhob muaj cov khoom sib xyaw, cov khoom siv tsis raug, noo noo, deformation ntawm lub thawv ntim, lossis kev puas tsuaj rau lub thawv. Txhua lub ntim khoom yuav tsum muaj cov kev tiv thaiv zoo sib xws.
Kev soj ntsuam pom tus qauv
Kev tiv tauj tus pin, lub qhov (socket pin) lossis cov khoom siv hluav taws xob yuav tsum tsis muaj deformation, dabtsi yog khoov, oxidation, av, thiab lwm yam. Siv vernier caliper thiab micrometer los xyuas seb cov khoom ntev npaum li cas thiab sab nraud yog nyob rau hauv tus qauv ntau yam.
Kev kuaj xyuas ua haujlwm
Siv ib lub multimeter los xyuas seb tus nqi tiv thaiv ntawm ob qhov kawg ntawm kev coj ua nyob rau hauv tus qauv. Muab cov khoom pin rau hauv 270 ± 5 degree tin melting rauv rau soldering tsis kam, tshem tawm ntawm lub cub tawg, thiab ntsuas nws txoj haujlwm 3 teev tom qab. Qhov kev ua haujlwm zoo ib yam nrog qhov ua ntej qhov kev sim thiab tsis muaj cua sov poob.
Kev ceev faj rau kev tshuaj xyuas kev ua haujlwm:
1. Hnav hnab looj tes tiv thaiv thaum kuaj
2. Weldability thiab vuam kub tsis kam yuav tsum raug rau 10PCS rau txhua batch
