Ib qho kev cuam tshuam ntawm tus pin positioning ntawm lub teeb kov hloov thiab lub PCB qhov chaw yuav cuam tshuam nws cov txheej txheem SMT mounting.Yog tias qhov kam rau ua kom haum yog qhov tseem ceeb, yuav muaj qee qhov kev pheej hmoo ntawm cov neeg kho tshuab kev ntxhov siab.Los ntawm kev ntsuas kev ua siab ntev ntawm qhov chaw ntawm tus pin ntawm lub teeb kov hloov thiab PCB qhov chaw qhov chaw, qhov tsawg kawg nkaus clearance ntawm tus pin positioning thiab qhov positioning qhov yog xam. ua -0.063mm, uas yog, muaj kev cuam tshuam me ntsis.Yog li, muaj kev pheej hmoo tias tus pin positioning ntawm lub teeb kov hloov tsis tuaj yeem muab tso rau hauv PCB qhov chaw qhov chaw zoo thaum SMT mounting.Cov xwm txheej hnyav tuaj yeem raug kuaj pom los ntawm kev tshuaj xyuas qhov muag ua ntej reflow soldering.Cov teeb meem me me yuav raug tso tseg rau cov txheej txheem tom ntej thiab yuav ua rau qee qhov kev ntxhov siab.Raws li hauv paus Square Sum tsom xam, Tus nqi tsis raug yog 7153PPM. 
Nws raug nquahu kom hloov qhov loj thiab qhov siab ntawm PCB qhov chaw ntawm 0.7mm +/ -0.05mm txog 0.8mm +/ -0.05mm.Kev soj ntsuam kev kam rau siab tau rov ua dua rau cov txheej txheem optimized.Cov txiaj ntsig tau pom tias qhov kev tshem tawm yam tsawg kawg nkaus nruab nrab ntawm qhov chaw nyob thiab qhov chaw qhov chaw yog + 0.037mm, thiab kev pheej hmoo ntawm kev cuam tshuam raug tshem tawm.
