Kho Hash Board

        Tsis siv neeg BGA rework tshuab rau asic hash board rapair

DH-G620 yog qhov kev sib raug zoo ntawm ntau lub tshuab rework, vim nws muaj

optical CCD kev sib raug zoo system thiab tsis siv neeg ua haujlwm rau kev rov ua haujlwm thiab kho ntawm

electronic boards.

Nrog touchscreen ntawm tus neeg teb xov tooj pem hauv ntej thiab ib qho chaw siv tau, uas yog

yooj yim rau kev kho lub rooj tsavxwm, ECU rework thiab kho lub khoos phis tawj laptop

thiab lwm yam.

Lub touchscreen suav nrog tag nrho cov lus txib siv los tswj cov txheej txheem rov ua haujlwm

ntawm SMD Cheebtsam thiab nti-qib ntawm cov khoom siv hluav taws xob.

Nruab nrog HD LCD thiab ntau lab pixles optical CCD, uas koj tuaj yeem tso nti / cov khoom siv

ntawm nws txoj cai ncej, qhov tseeb +/-0.01mm.

Adjustable kub-air-flow ceev (sab saum toj nozzle nkaus xwb), illumination siv ntawm lub prism

(sab saum toj thiab hauv qab sab), thiab khawm hloov ntawm lub teeb LED, khawm rau

hloov ntawm lub laser qhov chaw, khawm xwm ceev, USB chaw nres nkoj thiab lub davhlau ya nyob twg rau

txuas sab nraud thermocouple, tag nrho hauv txhua qhov, txhawm rau kom paub tseeb, txawm tias

koj yog ib tug bignner, nws yog ib qho yooj yim rau kev khiav lag luam.

Cov ntaub ntawv yooj yim

Siv cov txheej txheem rau lub tshuab BGA

Cov cuab yeej siv los ntawm lub tshuab suav nrog ob lub tshuab cua sov nrog kev yuam cua kub

(sab saum toj nozzle thiab hauv qab nozzle) thiab ib tug series ntawm IR preheating cheeb tsam nrog ceramic (hauv qab nkaus xwb).

1. Desoldering rau ib nti-qib lossis cov khoom siv

Tshem tawm lossis tshem tawm cov nti, xaiv qhov ntsuas kub kom zoo lossis tsuas yog teeb tsa

ib tug tshiab profile siv, kho motherboard ntawm ua hauj lwm platform, rau loj PCB siv a

nqaj txhawb.

2. Kub profile teeb

Kev ua haujlwm yooj yim interface rau qhov kub thiab txias, tus nqi thiab lub sijhawm teeb tsa, tsis siv neeg

curves generated, real-time kub yuav nyeem tau, sab nraud temperatuure tau

yuav pom ntawm qhov screen thiab. Tsis siv neeg them nyiaj raws li qhov profile

teeb tsa.

3. Lub nti cia li khaws

Chip yog khaws, ntxuav nti thiab motherboard, tos rau reballing los yog

pinting flux muab tshuaj txhuam. Tseeb, yog tias koj muaj cov chips tshiab, tsuas yog siv nws.

4. Optical CCD aliging system los ntawm mounting

Nrog kev pom kev sib cais uas tuaj yeem ua rau cov xim sib txawv rau cov chip thiab motherboard,

pom aliging zam misaligning, raug mus txog 0.01mm.

5. Chip soldering

Txhawm rau xaiv qhov kub thiab txias profile uas koj xav tau, nyem "Start" kom sov, thiab hla dhau

kiv cua yuav pib automatially tom qab soldering tag, tiv thaiv thiab nti zoo los ntawm

cua sov zog ntau dua.

Tsis tas li ntawd, ntawm no yog qee yam kev paub txog:

Lub tshuab BGA rau kev kho lub pcb siv ob hom: ob qhov kev tawm tsam txhuas cov lus qhia milled tom qab

nws qhov kev ncua deb nws txawv raws li qhov ntev ntawm pcb (kev hloov kho ntawm phau ntawv), los yog ntau yam hloov tau

universal jigs txhawb nrog siv pins (tsim kho pcbs ntawm cov duab tsis xwm yeem).

Lub software yog intuitive heev thiab tuaj yeem nkag tau los ntawm ob lub ntsiab zaub mov, cov ntawv qhia "Suav" thiab cov

"English" ntawv qhia zaub mov, tus neeg teb xov tooj tuaj yeem ua ntau pab pawg rau qhov kub thiab txias raws li nws xav tau, kom nws

tuaj yeem hu rov siv dua txhua lub sijhawm.

Rau txhua pab pawg, nws tuaj yeem ua haujlwm txog yim qhov kub thiab txias-kauj ruam ntawm sab saum toj thiab yim rau

sab hauv qab, rau txhua qhov uas nws muaj peev xwm them tsis tau ntau tshaj txhua txhua 30ms thiab ntxiv rau

Nws muaj peev xwm ua tau qhov kub ntawm IR ceramics uas yog siv los preheat tus so ntawm pcb

(lawv tau muab faib ua 3 qhov sib cais, ob sab sab nraud tuaj yeem qhib tau / xiam oob qhab ntawm nws tus kheej).

DH-G620 tsis tas yuav tsum tau npaj ua ntej rau Desoldering, positioning thiab Soldering, txawm tias koj yuav

kho hash board, ECU lossis computer thiab lwm yam.

Lub Y axis, lub taub hau sab saum toj nrog lub nozzle yog lub cev muaj zog, nrog kev siv lub Joystick, nws txav mus rau ob qho kev qhia,

ib qho kev sib thooj sensor nres qhov txav ntawm lub nozzle nyob rau hauv lub xub ntiag ntawm ib qho teeb meem.

Optical prism yog siv los kho cov ko taw ntawm cov khoom siv nrog cov ntaub qhwv ntawm pcb, tus neeg teb xov tooj,

los ntawm cov yeeb yaj kiab xim, pom ob txhais taw ntawm cov khoom thiab cov ntaub qhwv ntawm pcb, siv cov

micrometers los kho lawv ua ntej muab cov khoom tivthaiv ntawm pcb.

Siv cov thermocouple sab nraud nws tuaj yeem saib xyuas qhov ntsuas kub tiag tiag nyeem ntawm pcb hauv qhov

thaj chaw suav hais tias yog qhov tseem ceeb, lub thermal nkhaus yog qhia ntawm cov xim LCD zaub ua ke nrog rau sab saum toj thiab

Cov cua kub hauv qab kub thiab IR daim hlau.

Tag nrho cov thermal profiles tuaj yeem khaws cia los ntawm kev ua ib daim qauv ntawm cov duab nraaj uas pom ntawm lub vijtsam kov

tso saib, txuag lawv ntawm tus yuam sij USB hauv .bmp duab hom.

DH-G620 yog ib qho khoom siv zoo heev uas tsis tuaj yeem ploj hauv kev kho lub khw uas xav tau

npaj los ntsib tej xwm txheej ceev hauv txoj kev nyab xeeb thiab ceev.
