Dab tsi yog qhov yuav tsum tau ua rau PCBA ua thiab vuam?

Hauv kev ua PCBA, vuam yog txoj kev sib txuas tseem ceeb, kev txawj ntse ntawm PCBA ua, thiab yog ib txoj hauv kev tseem ceeb ntawm kev ua hlau. Cov teeb meem ntsig txog soldering raug txiav txim siab nyob rau txhua theem ntawm cov txheej txheem PCBA. Hauv qab no, Tecoo yuav qhia koj txog dab tsi yog qhov yuav tsum tau ua rau PCBA ntxiv rau vuam:

◆ Qhov siab ntawm tus pins ntawm qhov chaw soldering ntawm cov khoom siv plug-in yog 1.5-20mm. SMD cov khoom yuav tsum tiaj tus ntawm lub rooj tsavxwm, cov pob qij txha yuav tsum du yam tsis muaj burrs thiab me ntsis arc-puab, thiab cov solder yuav tsum tshaj 2/3 ntawm qhov siab ntawm qhov kawg soldering, tab sis yuav tsum tsis txhob siab tshaj qhov siab ntawm soldering. kawg. Tsawg dua tin, spherical solder pob qij txha los yog solder npog thaj ua rau thaj yog tag nrho cov phem;

◆ Qhov siab ntawm solder pob qij txha: qhov siab ntawm solder nce pins yuav tsum tsis pub tsawg tshaj 1 hli rau ib lub vaj huam sib luag, tsis tsawg tshaj li 0.5 hli rau ob lub vaj huam sib luag thiab yuav tsum tau nkag mus rau tin.

◆ Kev sib koom ua ke zoo: Nws yog conical thiab npog tag nrho lub ncoo.

◆ Solder sib koom nto: du thiab ci, tsis muaj pob dub, flux thiab lwm yam khib nyiab, tsis muaj pos, qhov, qhov pores, raug tooj liab thiab lwm yam tsis xws luag.

◆ Solder sib koom ua ke lub zog: ua kom ntub dej nrog cov ntaub qhwv thiab cov pins, tsis muaj qhov cuav thiab tsis tseeb.

◆ Hla ntu ntawm cov pob qij txha: Cov ko taw txiav ntawm cov khoom yuav tsum tsis txhob raug txiav mus rau qhov sib txuas ntau npaum li qhov ua tau, thiab tsis muaj qhov tshwm sim tawg ntawm qhov sib chwv ntawm cov pins thiab cov solder. Tsis muaj spikes thiab barbs ntawm tus ntoo khaub lig.

◆ Koob lub rooj vuam: Lub rooj zaum koob yuav tsum tau muab tso rau hauv lub rooj zaum hauv qab, thiab txoj hauj lwm yog qhov tseeb thiab qhov kev taw qhia raug. Tom qab lub rooj zaum koob yog welded, lub hauv qab ntab qhov siab yuav tsum tsis txhob ntau tshaj 0.5mm, thiab lub rooj zaum lub cev yuav tsum tsis txhob skewed tshaj lub silk screen ncej. Cov kab ntawm cov rooj zaum koob yuav tsum tau khaws cia kom zoo, thiab tsis pub muaj kev cuam tshuam lossis tsis sib xws.
