Yuav Siv BGA Chaw Nres Tsheb Npaum Li Cas

Kev ua haujlwm kom raug ntawm Dinghua BGA rework chaw nres tsheb yuav tsum nruj cov txheej txheem kom ntseeg tau qhov ntsuas kub

Tswj thiab muab txoj haujlwm raug kom tsis txhob muaj kev puas tsuaj rau lub motherboard lossis nti. Ntawm no yog cov kauj ruam tseem ceeb thiab kev ceev faj:

Thawj kauj ruam:
Muab tso rau thiab kho
Muab cov motherboard rau ntawm lub platform ua haujlwm, siv laser tso tawm lossis kho kho qhov muag txheej txheem kom ntseeg tau tias qhov chaw

Ntawm lub nti yog coaxial nrog lub tshuab cua sov, thiab siv Universal fixtures los txhim kho pcb los tiv thaiv kev tshais chaw. ‌

Kauj ruam thib ob:

Teeb profiles

Txhawm rau teem profile rau desoldering lossis soldering, txawm tias txoj hauj lwm ib yam, koj tuaj yeem tsim 5 txog 8 ntu rau Dinghua BGA roon

Chaw nres tsheb, xws li, tsis siv neeg BGA rhwork dh {{} A2E thiab dh- A5, yog tias koj xav pom yuav ua li cas teem, thov ntxiv kuv rau koj

WhatsApp / WeChat: {+8615768114827}}, Kuv tuaj yeem qhia koj.

Yuav ua li cas teem profiles ntawm BGA Reading Chaw nres tsheb ciav hlau DH - A5:

Kauj ruam thib peb:

Ua kom sov thiab sov -} nce theem
Pib lub cub kub loj - huab cua, qis} huab cua sov lub nti 80 ~ 250℃(ir 150-200 rau PCB board)

(cia liXaus plaub theem: preheating, cua sov, reflow, thiab cua txias) kom tso cov kev ntxhov siab hauv pawg thawj coj saib. ‌

PS: Yog tias koj tsuas yog soldered ib nti, tag nrho cov txheej txheem tiav lawm.

Yog tias koj nyuam qhuav desoldered ib nti, koj yuav tsum tau txuas ntxiv raws li hauv qab no.

Cov kauj ruam tawm:

Kev ntxuav thiab cog
Siv soldering wick los ntxuav cov pas dej tin rau ntawm lub hau ntxig. If the chip needs to be replaced, re-apply flux and reballing;

Cov nti txuas ntxiv xav tau ua kom tiav thiab ua tiav. ‌

Thib tsib kauj ruam:

Soldering thiab cua txias
Pheej rov ua kom sov sov rau qhov ntsuas kub mus rau solding kub nkhaus mus fuse pob thiab lub ncoo thiab tom qab ntawd ib txwm muaj

txias rau chav sov.

Kev tiv thaiv kev ntsuas
Kev tswj qhov kub thiab txias: kev ua kom sov ntau dhau yuav ua rau kev puas tsuaj, thaum muaj qhov kub tsis txaus yuav ua rau muaj kev txom nyem

soldering.
Nws raug nquahu kom ua raws cov khoom siv kom pom tseeb curve lossis cov chaw tsim khoom raug ua kom pom tseeb. ‌‌

Cov txheej txheem sib thooj: phau ntawv tshuab xav tau ib qho precision ntawm ± 0.01 hli, thaum siv tsis siv neeg ua tiav cov khoom siv siab dua

qhov tseeb los ntawm kev kho qhov muag.

Kev Ntsuam Xyuas System. ‌‌

Yuav Tsum Muaj Ib Cheeb Tsam: Qhov chaw ua haujlwm yuav tsum yog hluav taws xob zoo li qub, plua plav {} Pub dawb, thiab tswj tau kub ruaj khov,
Thaum tsis txhob muaj kev cuam tshuam loj heev lossis kev cuam tshuam zoo li qub. ‌‌

** Cov cuab yeej npaj khoom **: Siv tshwj xeeb deem muag, microscopes, flux muab tshuaj txhuam, soldering wick, txhuam thiab lwm yam cuab yeej
Txhawm rau pab tu thiab tshawb xyuas cov yas sib koom ua ke zoo(Yog tias koj muaj txaus budgt, koj tuaj yeem xav txog kev soj ntsuam xrreamTSHUAB QHO. Piv txwv li,
