Qhov zoo ntawm SMTreflow qhov cubtxheej txheem yog tias qhov kub thiab txias yog yooj yim los tswj, oxidation yuav zam tau thaum lub sij hawm soldering txheej txheem, thiab cov nqi ntawm cov khoom tsim los kuj yooj yim rau kev tswj.Muaj cov txheej txheem hluav taws xob cua sov hauv cov cuab yeej no, uas ua kom sov nitrogen rau qhov kub txaus thiab tshuab nws mus rau lub rooj tsav xwm hauv Circuit Court uas cov khoom tau muab tso rau hauv, kom lub solder ntawm ob sab ntawm cov khoom melts thiab bonds nrog lub ntsiab. lub rooj tsavxwm.TYTechyuav qhia ib co ntawm optimization txoj kev ntawm SMT reflow soldering txheej txheem ntawm no.
1. Nws yog ib qho tsim nyog yuav tsum teeb tsa SMT reflow soldering kub nkhaus thiab ua lub sijhawm ntsuas qhov ntsuas kub ntawm qhov nkhaus tsis tu ncua.
2. solder raws li reflow soldering kev taw qhia thaum lub sij hawm tsim PCB.
3. Thaum lub sij hawm SMT reflow soldering txheej txheem, lub conveyor siv yuav tsum tau tiv thaiv los ntawm vibrating.
4. Cov nyhuv reflow soldering ntawm thawj cov ntawv luam tawm yuav tsum tau kuaj xyuas.
5. Txawm hais tias SMT reflow soldering yog txaus, seb qhov saum npoo ntawm qhov sib koom ua ke yog du, txawm tias cov duab ntawm cov khoom sib koom ua ke yog ib nrab hli, qhov xwm txheej ntawm cov pob qij txha thiab cov khoom seem, qhov xwm txheej ntawm kev sib txuas txuas ntxiv thiab cov khoom siv hluav taws xob.Kuj xyuas cov khoom xws li kev hloov xim ntawm PCB nto.Thiab kho qhov kub thiab txias nkhaus raws li kev soj ntsuam xyuas.Thaum lub sij hawm tag nrho cov txheej txheem ntau lawm, qhov vuam zoo yuav tsum tau kuaj xyuas tsis tu ncua.
6. Tsis tu ncua tuav lub SMT reflow soldering.Vim lub sijhawm ua haujlwm ntev ntawm lub tshuab, cov organic lossis inorganic pollutants xws li solidified rosin txuas.Txhawm rau tiv thaiv cov pa phem thib ob ntawm PCB thiab ua kom muaj kev ua haujlwm zoo ntawm cov txheej txheem, kev tu thiab tu yuav tsum tau ua.
