Qhov twg yog qhov tsim nyog rau PCB los ua ke ntawm kev xaiv vuam thiab yoj vuam?

Kev xaiv vuam thiab yoj soldering feem ntau yog siv rau hauvPCB sib dhos pov thawj.Txawm li cas los xij, txhua txoj hauv kev no muaj nws qhov zoo thiab qhov tsis zoo.Cia peb saib ntawm kev xaiv vuam thiab yoj vuam - qhov twg yog qhov zoo dua rau SMT nti ua, pov thawj thiab sib dhos?

Vuam soldering

Wave soldering, tseem hu ua reflow soldering, yog ua nyob rau hauv ib qho chaw tiv thaiv roj, vim nws paub zoo tias kev siv cov nitrogen tuaj yeem txo qhov muaj peev xwm ntawm vuam tsis xws luag.

Wave soldering txheej txheem muaj xws li:

1. Siv lub tsho tiv no los ntxuav thiab npaj lub rooj sib txoos.Qhov no yog qhov tsim nyog vim tias tej impurities yuav cuam tshuam rau cov txheej txheem vuam.

2. Circuit Board preheating.Nws yuav ua kom lub flux thiab xyuas kom meej tias lub rooj tsavxwm tsis raug thermal shock.

3. Lub PCB kis tau los ntawm cov molten solder.Raws li lub rooj tsav xwm hauv Circuit Court txav ntawm lub crest qhia kev tsheb nqaj hlau, kev sib txuas hluav taws xob yog tsim los ntawm cov khoom siv hluav taws xob, PCB pins thiab solder.

Wave soldering yog qhov zoo tshaj plaws hauv kev tsim khoom loj, tab sis nws kuj muaj nws cov kev tsis zoo, feem ntau suav nrog:

1. kev siv ntawm solder yog siab heev

2. nws noj ntau flux

3. Wave soldering siv ntau lub zog

4. Nws siv nitrogen ntau

5. Wave soldering yuav tsum tau rov ua dua tom qab yoj soldering

6. Nws kuj yuav tsum tau ntxuav lub yoj lub qhov tais thiab cov khoom siv vuam

7. Nyob rau hauv ib lo lus, tus nqi ntawm yoj soldering yog siab heev, thiab cov nqi khiav hauj lwm raug suav tias yog ze li tsib npaug ntawm cov kev xaiv vuam.

Xaiv vuam

Kev xaiv vuam yog ib hom yoj soldering, uas yog siv los txhim kho cov khoom siv SMT ua ke nrog cov khoom hauv lub qhov.Selective yoj soldering tuaj yeem tsim cov khoom me me thiab sib dua.

Selective welding txheej txheem muaj xws li:

Daim ntawv thov ntawm flux ntawm cov khoom yuav tsum tau welded / Circuit Court board preheating / solder nozzle rau vuam tshwj xeeb Cheebtsam.

Qhov zoo ntawm kev xaiv welding:

1. Flux yog siv rau hauv zos, yog li tsis tas yuav thaiv qee yam khoom

2. Tsis tas yuav tsum muaj flux

3. Nws tso cai rau koj los teeb tsa qhov sib txawv rau txhua qhov khoom

4. Tsis tas yuav siv cov khoom kim heev aperture wave soldering tais

5. Nws tuaj yeem siv rau cov rooj sib tham hauv Circuit Court uas tsis tuaj yeem yoj soldering

6. Zuag qhia tag nrho, nws cov txiaj ntsig ncaj qha rau cov neeg siv khoom yog tus nqi qis

Yog li ntawd, yuav ua li cas xaiv tus tsim PCB los ua ke txoj kev ua haujlwm yuav tsum tau ua kom tiav los ntawm cov neeg siv khoom raws li cov yam ntxwv ntawm cov khoom.
