LGA Rework
1. LGA yog Land Grid Array uas yog hom pakage technology; 2. Tsis tas yuav desolder nws cov PCBa me me hauv LGA; 3. Tag nrho LGA yuav raug tshem tawm siv tshwj xeeb jig; 4. Zoo dua tiv thaiv LGA los ntawm cua sov.

Siab tsis siv neeg LGA rework tshuab nrog kev jig thiab nozzles
(Land Grid Array) Ib pob chip nrog kev sib txuas siab heev. LGAs txawv ntawm cov chips ib txwm muaj nrog cov pins uas tau muab tso rau hauv lub qhov (socket). Ib qho LGA nti muaj cov ntaub qhwv tiaj tiaj nyob hauv qab ntawm nws cov pob uas kov cov neeg sib cuag ntawm lub qhov (socket motherboard).
Raws li kev pom ntawm LGA cov qauv tshwj xeeb, thiab kev rov ua haujlwm sai & kev ua haujlwm siab los kho, peb muab kev pabcuam customized rau kev kho LGA chips sib txawv.

Cov txheej txheem rau LGA rework
1. npaj ib jig raws li hauv qab no:
Customizing ib jig raws li LGA qauv, dav, ntev thiab qhov siab thiab lwm yam uas tuaj yeem ua tau
xyuas kom tag nrho LGA tuaj yeem khaws tau thiab tsis txhob ua kom puas cov nti sab hauv.
2. Tshem tawm / tshem tawm
Tom qab desoldering LGA, tag nrho LGA tuav los ntawm jig tau muab tso rau
lub tshuab chip-feeder tos kev tu.
Chip-feeder thiab optical CCD lub koob yees duab ua haujlwm ua ke, ib txwm tau txais
qhib thiab kaw.
3. Siv cov nti tshiab los yog tsuas yog ib lub nti tshiab tag nrho insead.
Koj tuaj yeem zam lub lim tiam ntawm kev ncua sij hawm thiab qhov sib piv ntawm cov nyiaj tseem ceeblos ntawm kev siv LGA rework. Thaum lub sijhawm ncua zoo li tsis muaj kev zam, kev ua haujlwm zoorework yuav tso cai rau koj ua tau raws li koj cov neeg siv khoom lub sijhawm. DH (Dinghua) muajua tiav kev paub dhau los rau ntau tus neeg siv khoom tseem ceeb, suav nroglos ntawm cov tuam txhab loj, piv txwv li, Google, Teleplan, Huawei thiab Foxconn thiab lwm yam.,rau cov khw me me, xws li, lub khw kho tus kheej, raug xaiv qhov chaw pabcuam tom qab muagthiab lwm yam, ntau tus uas muaj cov ntaub ntawv nyuaj uas xav tau kom muaj kev lees paubnyob rau hauv kev ntseeg siab-tseem ceeb industries.
4. Pom pom kev kho qhov muag CCD txheej txheem
Tom qab aligning (chip yuav tsum muab tso rau hauv nws txoj hauj lwm zoontawm lub motherboard), lub nti yuav cia li nqarau solder.
5. Tsis siv neeg Solder
Tsis siv neeg mount rau nws cov motherboard, cia li ua kom sovsiv cov cua kub cua thiab infrared cua sov, txawm tias cia txias tom qabua hauj lwm tiav.
Vim li cas thiaj siv DH (Dinghua) rau LGA rework?
Advanced soldering cov txheej txheem thiab cov tshuab tsim nyog tau tsim,thiab zoo ib yam, rov ua dua, thiab tshaj txhua qhov kev cia siab rau LGA rework, uas nquagently necessitates tsim cov cim jig thiab stencils, board solder masking,
thiab feem ntau txawm tiaskev sib txuas ntawm cov ntaub qhwv tshiabrau PCB. Tom qab lub rework yog fin-los, lub rooj tsavxwm raug tshuaj xyuas siv endoscopes thiab X-rays los xyuas kom meej qhov rewo-rk txoj kev ntseeg siab thiab kev ncaj ncees. Cov tuam txhab cia siab rau DH (Dinghua) los ua qhov no
ser-vice vim peb cov txuj ci thiab kev saib xyuas kom meej thaum sau cov LGAs los ntawm circ-uit boards thaum cov khoom siv tsis tau yooj yim.
DH (Dinghua)muaj kev paub tob hauv kev tsim cov kev daws teeb meem rau kev rov ua haujlwm dua LGAs
thiab lwm yam khoom siv, xws li, X-ray kuaj tshuab thiab X-ray suav tshuab thiab lwm yam.
