Reflow qhov cubcov kauj ruam ua haujlwm
1. Txheeb xyuas tias muaj cov khib nyiab hauv cov khoom siv, ua haujlwm zoo ntawm kev tu, kom muaj kev nyab xeeb, qhib lub tshuab, xaiv qhov kev tsim khoom los qhib qhov kub thiab txias.
2. Reflow qhov cub qhia dav yuav tsum tau kho raws li qhov dav ntawm PCB, qhib lub thauj cua, mesh siv thauj, cua txias kiv cua.
3. Reflow soldering tshuabKev tswj qhov kub thiab txias muaj cov hmoov txhuas siab (245 ± 5) ℃, cov khoom siv lead ua tin cub taws kub tswj ntawm (255 ± 5) ℃, preheating kub: 80 ℃ ~ 110 ℃.Raws li cov tsis tau muab los ntawm cov txheej txheem vuam ntau lawm nruj me ntsis thiab nruj tswj lub reflow tshuab computer tsis teeb tsa, sau cov reflow tshuab tsis raws sij hawm txhua hnub.
4. nyob rau hauv thiaj li yuav successively tig ntawm qhov kub thiab txias mus rau lub teeb kub thaum koj tuaj yeem pib dua, PCB, lub rooj tsavxwm, tshaj lub rooj tsavxwm them nyiaj rau cov kev taw qhia.Xyuas kom meej tias qhov kev ncua deb ntawm 2 lub rooj sib law liag ntawm txoj siv conveyor tsis pub tsawg tshaj 10 hli.
5. Lub reflow soldering conveyor siv dav hloov mus rau qhov tsim nyog txoj haujlwm, qhov dav ntawm txoj siv conveyor thiab flatness thiab kab board, xyuas cov khoom yuav tsum tau ua tiav batch tooj thiab lwm yam kev xav tau.
6. Lub tshuab me me reflow soldering yuav tsum tsis txhob ntev dhau, qhov kub thiab txias dhau los ntawm qhov tshwm sim ntawm tooj liab platinum blistering;solder pob qij txha yuav tsum du thiab ci, lub rooj tsav xwm Circuit Court yuav tsum yog tag nrho cov ntaub qhwv ntawm lub tin;Cov kab tsis zoo yuav tsum tau rov ua dua, qhov thib ob rov ua dua yuav tsum tau ua tom qab txias
7. yuav tsum hnav cov hnab looj tes los khaws cov khoom siv PCB, tsuas yog kov ntawm ntug ntawm PCB, ua 10 cov qauv hauv ib teev, xyuas qhov tsis zoo, thiab sau cov ntaub ntawv.Thaum lub sij hawm tsim cov txheej txheem, yog tias koj pom tias qhov tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm kev tsim khoom, koj tsis tuaj yeem kho qhov tsis muaj koj tus kheej, koj yuav tsum tau ceeb toom rau tus kws kho mob tam sim ntawd.
8. Ntsuas qhov kub thiab txias: ntsaws lub sensor tig mus rau hauv lub tester qhov tau txais lub qhov (socket), qhib lub tester fais fab hloov, tso lub tester rau hauv lub reflow solder nrog lub qub PCB board mus rau reflow solder, tshem tawm lub tester nrog lub computer nyeem. cov ntaub ntawv kub tau sau tseg thaum lub sij hawm reflow soldering txheej txheem, uas yog, cov ntaub ntawv qub rau reflow soldering tshuab qhov kub nkhaus.
9. Yuav tau soldered lub rooj tsavxwm raws li ib tug naj npawb, npe, thiab lwm yam.Txhawm rau tiv thaiv kev sib xyaw ua ke kom tsim cov khoom tsis zoo.
Reflow soldering qhov cub ua haujlwm ceev faj
1. Tsis txhob kov lub mesh txoj siv thaum lub sijhawm ua haujlwm thiab tsis txhob cia cov dej los yog cov roj stains poob rau hauv lub cub tawg kom tsis txhob kub hnyiab.
2. Kev ua haujlwm vuam yuav tsum xyuas kom muaj qhov cua, tiv thaiv cov pa phem, cov neeg ua haujlwm yuav tsum hnav khaub ncaws ua haujlwm zoo, hnav lub npog ntsej muag zoo.
3. Feem ntau sim cov cua sov ntawm cov hlau, kom tsis txhob muaj kev laus.
