Cov lus qhia txog kev ua haujlwm ntawm phau ntawv solder tshuab luam ntawv

Tso thiab positioning ntawmphau ntawvsolderluam tawmer

Nyob rau hauv SMT ntau lawm kab, luam ntawv yog kom plam lub solder muab tshuaj txhuam rau hauv cov ntaub so ntswg sib xws ntawm PCB los npaj rau thaj tsam tom ntej.Phau ntawv solder tshuab luam ntawv yog hais txog cov txheej txheem ntawm kev siv lub tshuab luam ntawv los ntawm kev siv lub tshuab luam ntawv phau ntawv.
Cov txheej txheem kev lag luam ntawm phau ntawv siv lub tshuab luam ntawv feem ntau suav nrog phaj tso, tso, luam ntawv, phaj noj thiabntxuav steel mesh.

1. Tsau steel mesh
   Siv cov cuab yeej kho kom kho cov hlau mesh ntawm lub tshuab luam ntawv.Tom qab kho, xyuas kom meej tias cov hlau mesh thiab PCB nyob hauv kev sib cuag.Tsis muaj kev sib cuag tsis sib xws los yog ib sab tuaj yeem tshwm sim, txwv tsis pub nws yog ib qho yooj yim ua rau lub cev qhuav dej ntawm lub tshuab luam ntawv luam ntawv, cuam tshuam rau kev luam ntawv zoo thiab kev pabcuam lub neej ntawm steel mesh.
2. Qhov chaw ntawm PCB
   Phau ntawv luam ntawv, PCB feem ntau yog siv lub phaj ntug positioning, uas yog, positioning raws li txoj hauj lwm ntawm qhov chaw ntawm lub rooj tsavxwm.Tom qab muab tso rau, lub mesh ntawm cov hlau mesh yuav tsum raug ua raws li cov ntaub ntawv sib xws ntawm PCB.Yuav kom muaj kev sib koom ua ke zoo, nws feem ntau yuav tsum tau muab tshuaj txhuam thiab cov ntaub qhwv ntsej muag dislocation tsawg dua 10%.

Tes luam 4 kauj ruam

1. Cov txheej txheem luam ntawv feem ntau muaj plaub kauj ruam hauv qab no.
   (1) qhov kub thiab sib tov zoo solder paste leveled thiab glued ntawm cov hlau net, solder paste tsis txhob siv ntau dhau, nrog rau kev luam ntawv nrog qhov sib ntxiv.
2. Lub PCB yuav tsum luam tawm yuav tsum muab tso rau hauv qhov tseeb ntawm lub rooj luam ntawv, muab tso rau hauv cov hlau mesh, thiab xyuas seb lub mesh puas raug raws li PCB solder pad.
3. Scrape lub solder paste nrog ib tug scraper kom lub solder muab tshuaj txhuam rau ntawm cov hlau net yob thiab luam tawm los ntawm sab saum toj mus rau hauv qab raws li cov kev taw qhia ntawm PCB.
4. Tshem tawm cov ntawv luam tawm PCB los ntawm lub rooj luam ntawv.Tshawb xyuas seb puas muaj cov dej xau, ntau cov tin, tsawg dua tin, txawm tias luam ntawv tshwm sim.Yog tias tsis tsim nyog, ntxuav tawm cov tshuaj txhuam nrog lub tshuab ntxhua khaub ncaws thiab rov luam dua tom qab lub rooj tsavxwm qhuav
