Vuam yog SMT nti ua cov txheej txheem yog qhov tseem ceeb txuas, yog tias nyob rau hauv qhov txuas no nthuav qhia qhov yuam kev yuav cuam tshuam ncaj qha rau cov txheej txheem ua haujlwm ntawm lub rooj tsavxwm ua tsis tiav thiab txawm tias muab pov tseg, yog li hauv vuam yuav tsum tuav txoj kev vuam kom raug, nkag siab txog cov teeb meem tseem ceeb ntawm kev saib xyuas kom tsis txhob muaj teeb meem. teeb meem.
1. nyob rau hauv lub nti ua ntej welding ntawm cov ntaub qhwv coated nrog flux, siv ib tug soldering hlau rau ib zaug, kom tsis txhob cov ntaub yog tsis zoo tinned los yog oxidized, tsim tsis zoo welding, lub nti yog feem ntau tsis tas yuav nrog. .
2. Siv cov tweezers ua tib zoo muab PQFP nti rau ntawm lub rooj tsavxwm PCB, ua tib zoo saib xyuas kom tsis txhob ua rau cov pins puas.Teem nws nrog cov ntaub qhwv thiab xyuas kom tseeb tias cov nti tau muab tso rau hauv qhov tseeb.Teem qhov kub ntawm cov hlau soldering rau ntau tshaj 300 degrees Celsius, dipped lub hau ntawm cov hlau rau hauv ib qho me me ntawm cov solder, nias rau ntawm lub nti nrog cov cuab yeej uas tau ua raws li txoj hauj lwm, ntxiv ib qho me me ntawm solder mus rau qhov chaw. ob diagonally positioned pins, tseem nias rau ntawm nti thiab solder ob diagonally positioned pins kom lub nti yog tsau thiab txav tsis tau.Tom qab soldering tus kab pheeb ces kaum, xyuas qhov chaw ntawm lub nti los ntawm qhov pib kom pom tias nws yog raws li txoj cai.Yog tias tsim nyog, kho lossis tshem tawm thiab kho qhov chaw ntawm PCB los ntawm kos.
3. Pib welding tag nrho cov pins, koj yuav tsum tau ntxiv solder rau lub ntsis ntawm lub soldering hlau, tag nrho cov pins yuav coated nrog solder kom cov pins adheres rau cov ntub dej.Kov qhov kawg ntawm txhua tus pin ntawm cov nti nrog lub ntsis ntawm cov hlau soldering kom txog thaum koj pom cov hlau ntws mus rau hauv cov pins.Thaum soldering, lo rau ntawm qhov kawg ntawm cov hlau soldering thiab cov pins soldered nyob rau hauv parallel kom tsis txhob sib tshooj vim yog solder ntau dhau.
4. Tom qab soldering tag nrho cov pins, ntub tag nrho cov pins nrog solder kom huv si solder.Z tom qab siv cov tweezers los xyuas seb puas muaj cov khoom cuav, xyuas qhov ua tiav, los ntawm Circuit Court board coated nrog flux, yuav yooj yim rau SMD resistive Cheebtsam solder ib co, koj tuaj yeem ua ntej hauv qhov taw tes ntawm lub tin, thiab tom qab ntawd muab tso rau. ib qho kawg ntawm cov khoom, nrog tweezers los tuav cov khoom, solder ntawm ib kawg, thiab tom qab ntawd saib seb nws puas yog muab tso rau;Yog hais tias nws tau raug muab tso, ces solder rau lwm yam Yog hais tias nws yog, solder rau lwm kawg.Yuav tsum muaj ntau yam kev xyaum ua kom paub txog kev txawj ntse.
Cov yam ntxwv ntawm NeoDen IN12Creflow qhov cub
1. Ua-nyob rau hauv vuam fume filtration system, zoo filtration ntawm teeb meem gases, zoo nkauj tsos thiab ib puag ncig tiv thaiv, ntau nyob rau hauv txoj kab nrog kev siv high-end ib puag ncig.
2. Cov kev tswj xyuas muaj cov yam ntxwv ntawm kev sib koom ua ke siab, cov lus teb raws sij hawm, tsis tshua muaj nqi, kev saib xyuas yooj yim, thiab lwm yam.
3. Kev siv cov khoom siv high-performance aluminium alloy cua sov phaj hloov cov cua sov raj, ob qho tib si txuag hluav taws xob thiab txuag hluav taws xob, piv nrog cov reflow qhov cub zoo sib xws hauv kev ua lag luam, qhov sib txawv ntawm qhov kub ntawm sab nraud yog txo qis.
4. Kev tsim hluav taws xob tiv thaiv hluav taws xob, lub plhaub kub tuaj yeem tswj tau zoo.
5. Kev tswj kev txawj ntse, siab-rhiab heev kub sensor, zoo kub stabilization.
6. Kev cai-tsim khiav tsav lub cev muaj zog raws li cov yam ntxwv ntawm B-hom mesh siv, kom ntseeg tau tias tsis sib xws ceev thiab lub neej ntev.
