BGA rework chaw nres tsheb ua dab tsi

BGA soldering chaw nres tsheb, tseem hu ua BGA rework chaw nres tsheb lossis BGA desoldering chaw nres tsheb, yog cov cuab yeej tshwj xeeb rau kev daws teeb meem BGA chip soldering. Vim tias qhov yuav tsum tau muaj qhov kub thiab txias rau BGA chip soldering, cov cuab yeej siv cua sov xws li cov phom cua kub tsis tuaj yeem ua tau raws li nws qhov kev tswj xyuas qhov kub thiab txias.

Cov cuab yeej siv peb lub - qhov kub thiab txias qhov cua sov tshuab thiab tshuab cua sov infrared kom ua tau raws li cov cua sov sib xws los ntawm cov cua sov sab saud thiab qis dua. Nws yog txawm peem rau nrog ib tug optical alignment system thiab lub tshuab nqus tsev twj tso kua mis nti suction ntaus ntawv, thiab txhawb ± 2℃kub tswj qhov tseeb thiab tiag -lub sij hawm kub nkhaus zaub ua haujlwm.

Nws cov haujlwm ua haujlwm suav nrog ntu preheating, ntu tiv thaiv tshav kub, ntu cua sov, ntu vuam thiab ntu txias.

Nws tuaj yeem hloov kho rau qhov ntau thiab tsawg ntawm 0.8 × 0.8mm mus rau 80 × 80mm, thiab kev kho kom zoo tshaj 98%. Cov cuab yeej muab faib ua peb pawg: phau ntawv, semi- tsis siv neeg thiab tsis siv neeg puv.
Cov qauv semi- tsis siv neeg siv lub dichroic prism imaging system kom ua tiav ± 0.01mm qhov tseeb qhov chaw. Cov khoom tseem ceeb muaj xws li lub taub hau sab sauv / qis, cov khoom siv thoob ntiaj teb, ntsuas qhov ntsuas kub thiab siab - txhais cov vijtsam kov. Qee cov qauv tau nruab nrog kev saib xyuas kev kho. Nws yog ib qho tsim nyog los lov tes taw ob - qhov kub thiab txias qauv thaum xaiv tus qauv.

Nws kuj ua tau raws li qhov xav tau ntawm cov neeg kho tshuab qhov chaw rau PCB tuab ntawm 0.3-20mm, thiab ua tiav kev sib dhos nrawm los ntawm V-shaped slots thiab laser positioning teeb. Thaum vuam, koj yuav tsum tau kho cov nti mus rau qhov chaw nruab nrab ntawm lub qhov hluav taws xob sab sauv thiab sab qis, thiab siv lub clamp los kho cov motherboard kom tsis txhob deformation.
