Cov txheej txheem thiab cov txheej txheem los txhim kho cov txiaj ntsig ntawm Tes-welded BGA Rework

BGA rework kev lag luam yog kev lag luam uas yuav tsum tau muaj peev xwm ua haujlwm siab heev. BGA nti rework feem ntau muaj ob txoj hauv kev,

uas yog BGA rework chaw nres tsheb thiab phau ntawv kub cua phom vuam. General Hoobkas lossis khw kho yuav xaiv BGA rework chaw nres tsheb,

vim tias qhov kev vam meej vuam yog siab thiab kev ua haujlwm yooj yim, tsis muaj qhov yuav tsum tau ua rau tus neeg teb xov tooj, ib-

khawm ua haujlwm, haum rau batch kho. Hom thib ob ntawm phau ntawv welding thiab phau ntawv welding muaj cov txuj ci siab

yuav tsum tau, tshwj xeeb tshaj yog rau loj BGA chips. Yuav ua li cas phau ntawv soldering txhim kho cov txiaj ntsig ntawm bga rework?

Txhim kho phau ntawv vuam BGA rov qab kho tus nqi txoj kev.

Nws yog qhov zoo tiag tiag uas tuaj yeem txuas BGA ntawm tes vim tias tam sim no muaj ntau thiab ntau BGA-pob chips. Ntau tus neeg

tseem ntshai ntawm tes soldering bga, feem ntau vim hais tias hom ntim ntim no kim heev. Qhov tseeb, tsuas yog ntau qhov kev sim

tuaj yeem ua tiav. Hais ob peb yam uas yuav tsum nco ntsoov: Tom qab tshem tawm BGA tus tswv, nco ntsoov ua cov tin, vim tias tom qab rhuav tshem

qee qhov de-tin, lub ntsiab tswj thiab cov motherboard yuav tsum tsim, koj tuaj yeem muab cov tin muab tshuaj txhuam kom tau cov hlau rub, yog li

xyuas kom zoo thaum tshuab, qhov kub thiab txias yuav tsum tsis txhob siab dhau los yog 280. Cov phom cua yuav tsum tsis txhob nyob ze rau lub tin.

phaj. Yog tias koj xav co lub phom cua txav, qhov chaw tin yuav tsis khiav ncig. Lub tin qhov chaw ntawm thawj tin cog yog tsis tas

Uniform heev, tuaj yeem khawb nrog kev phais, muaj qhov tsis sib xws los sau cov tin thiab ces tshuab; cog BGA tuaj yeem cim rau ntawm BGA

flux, nqa rab phom cua tshuab kom sib npaug kom BGA tus tswv ntawm lub vuam sib txuas sib npaug; BGA cog rau ntawm lub motherboard thaum Ua si

ntau flux, qhov no tuaj yeem txo qhov melting point, thiab tso cai rau BGA ua raws li cov flux thiab cov tin point ntawm lub motherboard txuas.

Zoo, xav tias tom qab lub tshuab tuaj yeem siv cov tweezers maj mam taw tes BGA ntug sab laug thiab sab xis kom ntseeg tau tias kev sib cuag zoo. Txoj kev no tuaj yeem siv tau

rau me me BGA chips, tab sis rau cov chips loj xws li Northbridge, qhov kev vam meej yog qis dua. Qhov loj BGA nti rau desoldering yog

pom zoo kom siv Dinghua BGA rework chaw nres tsheb, uas tuaj yeem txhim kho BGA rework kho cov txiaj ntsig.
