DH-6500 INFRARED BGA rework chaw nres tsheb
Ib qho Infrared BGA Rework Chaw Nres Nkoj yog cov cuab yeej tshwj xeeb siv hauv kev lag luam hluav taws xob los kho lossis rov ua haujlwm Ball Grid Array (BGA) cov khoom ntawm cov ntawv luam tawm Circuit Board (PCBs). BGAs yog ib hom ntawm qhov chaw-mount ntim khoom siv rau kev sib xyaw ua ke, qhov twg cov kev sib txuas tau tsim los ntawm cov khoom sib txuas ntawm cov khoom siv hauv qab ntawm cov khoom siv.
DH-6500 universal infrared kho complex nrog digital kub tswj thiab ceramic cua sov rau Xbox,

Qee qhov kev txawj ntse txog IR BGA rework chaw nres tsheb
Pre-operative Knowledge:
Tus nqi ntawm qhov kub nce nyob rau hauv ib cheeb tsam uas tsis muaj txhuas preheating feem ntau yog tswj ntawm 1.2-5 degree / s (thib ob). Qhov ntsuas kub hauv cheeb tsam preheating feem ntau tsawg dua 160 degree, thiab qhov kub ntawm qhov rwb thaiv tsev yog 160-190 degree. Lub ncov kub yog feem ntau tswj ntawm 235-245 degree, nrog rau qhov kub thiab txias rau 10-45 vib nas this. Lub sij hawm los ntawm qhov kub nce mus rau qhov siab tshaj plaws yog li 1.5 mus rau 2 feeb.
Lub melting point ntawm txhuas solder yog 183 degree, thaum lub melting point ntawm lead-free solder paste yog 217 degree. Thaum qhov kub nce mus txog 183 degree, cov hmoov lead-muaj cov tshuaj nplaum pib yaj. Vim nws cov khoom siv tshuaj, qhov tseeb melting point ntawm solder hlaws yog siab dua li ntawm solder paste.
Kev paub dav dav ntawm lub tshuab:
1,Siv dav:Sab saum toj qhib + hauv qab-sab tsaus nti infrared.
2,Peb Temperature Zone Models:Cua kub + radiant tshav kub + tsawg tsaus nti infrared teeb.
3,Tag nrho-liab tsos:Upper infrared + qis qis infrared. Cov ntsiab lus tseem ceeb: Cov txheej txheem cua sov thiab cov sij hawm kub sib txawv nyob ntawm seb hom khoom. Kev taw qhia txog cua sov yog raws li nram no:
Cua kub cua sov:Siv lub hauv paus ntsiab lus ntawm huab cua hloov pauv, muab siab-precision, tswj tau cua sov. Kho cov huab cua ntim thiab cua ceev ua tau zoo ib yam thiab tswj tau cua sov. Thaum lub sij hawm vuam, cua sov yog hloov los ntawm lub cev ntawm BGA nti, ua rau qhov sib txawv ntawm qhov kub thiab txias ntawm cov hlaws hlaws thiab cov cua kub qhov hluav taws xob. Kev ntsuas kub yuav txawv nyob ntawm tus neeg tsim khoom, thiab cov ntaub ntawv hauv daim ntawv dawb no siv rau txhua tus qauv Dinghua Technology. Cov yam ntxwv no yuav tsum tau txiav txim siab thaum teeb tsa, thiab kev ua haujlwm ntawm cov hlaws hlaws yuav tsum tau nkag siab thiab teeb tsa raws li.
Rau qhov sib txawv ntawm qhov kub thiab txias (saib rau cov chaw tsim khoom cov lus qhia rau cov chaw tshwj xeeb), nws yog ib qho tseem ceeb uas yuav tau kho qhov kub siab tshaj plaws ua ntej. Teem lub siab kub tus nqi (235 degree rau tsis muaj hlau lead, 220 degree rau cov khoom siv lead ua) thiab khiav BGA chaw nres tsheb kho cua sov. Thaum cua sov, saib xyuas tag nrho cov txheej txheem, tshwj xeeb tshaj yog tias qhov ntsuas kub ntawm lub rooj tsavxwm tshiab tsis paub. Thaum qhov kub siab tshaj 200 degree, tshawb xyuas cov txheej txheem melting ntawm lub pob solder hauv thaj thaj tsam ntawm BGA. Siv tweezers kov lub thaj; yog tias nws txav, qhov kub thiab txias txaus. Thaum BGA nti pib dab dej, sau qhov kub thiab txias tso tawm ntawm lub cuab yeej lossis touchscreen thiab lub sijhawm ua haujlwm. Qhov zoo tshaj plaws kub yuav tsum tau khaws cia rau 10-20 vib nas this tom qab ncav cuag lub melting point.
Kab hauv qab:Thaum BGA raug tsim, cov pob solder yuav pib sib cais tom qab ncav cuag qhov kub siab tshaj li ob peb feeb. Tsuas yog qhov kub siab tshaj plaws ntawm qhov ntsuas kub yuav tsum tau teem rau qhov kub siab tshaj plaws tas li rau N + 20 vib nas this. Rau lwm cov txheej txheem, xa mus rau qhov ntsuas kub ntawm qhov nkhaus uas muab los ntawm cov chaw tsim khoom. Feem ntau, tag nrho cov txheej txheem rau cov hlau lead yuav tsum tau tswj nyob rau hauv kwv yees li 210 vib nas this, thiab cov txheej txheem txhuas tsis pub dhau 280 vib nas this. Lub sijhawm yuav tsum tsis txhob ntev dhau los kom tsis txhob muaj kev puas tsuaj rau PCB thiab BGA.
