Hauv lub ntiaj teb ntawm cov khoom siv hluav taws xob uas hloov zuj zus, kev tsim cov ntawv luam tawm Circuit Board (PCB) yog ib qho txheej txheem tseem ceeb uas xav tau kev ua kom raug thiab kev ntseeg siab. Ib qho ntawm cov kev nce qib tseem ceeb tshaj plaws hauv daim teb no yog kev siv granite gantry, uas muaj ntau yam zoo uas ua rau muaj kev ua haujlwm zoo thiab zoo ntawm PCB ntau lawm.
Granite gantry yog lub npe nrov rau nws qhov ruaj khov thiab rigidity zoo heev. Tsis zoo li cov ntaub ntawv ib txwm muaj, granite tsis yooj yim rau thermal expansion thiab contraction, ua kom ntseeg tau tias lub gantry tswj nws qhov tseeb txawm tias nyob rau hauv qhov kev hloov pauv ib puag ncig. Qhov kev ruaj khov no yog qhov tseem ceeb hauv kev tsim PCB, vim tias txawm tias qhov kev hloov pauv me me tuaj yeem ua rau muaj qhov tsis zoo thiab kev ua haujlwm tsis zoo.
Lwm qhov zoo ntawm granite gantry yog nws cov khoom zoo heev rau kev nqus dej. Hauv kev tsim PCB, kev co tuaj yeem cuam tshuam tsis zoo rau qhov tseeb ntawm cov txheej txheem machining. Granite qhov ceev thiab qhov hnyav ntuj pab nqus kev co, ua rau kev ua haujlwm du thiab raug dua. Qhov no tseem ceeb heev thaum cuam tshuam nrog cov qauv tsim nyuaj thiab kev kam rau siab nruj uas feem ntau pom hauv cov PCB niaj hnub no.
Tsis tas li ntawd xwb, lub gantry granite no tiv taus kev hnav thiab tsim kua muag heev, uas txhais tau tias cov nqi kho qis dua thiab lub neej ua haujlwm ntev dua. Qhov kev ruaj khov no yog qhov tseem ceeb rau cov tuam txhab tsim khoom uas tab tom nrhiav kev ua kom zoo dua lawv cov txheej txheem tsim khoom thiab txo qhov tsis ua haujlwm. Yog tias tsis tshua muaj kev kho lossis hloov pauv ntau zaus, cov tuam txhab tuaj yeem tsom mus rau kev nce kev tsim khoom thiab ua tau raws li kev xav tau ntawm kev ua lag luam.
Tsis tas li ntawd xwb, qhov zoo nkauj ntawm lub gantry granite tsis tuaj yeem tsis quav ntsej. Nws qhov zoo nkauj thiab ci ntsa iab tsis yog tsuas yog ua kom qhov chaw ua haujlwm zoo dua xwb tab sis kuj qhia txog kev cog lus rau kev tsim khoom zoo thiab kev ua haujlwm raug. Qhov no tuaj yeem cuam tshuam zoo rau cov neeg siv khoom pom thiab pab lub tuam txhab tsim nws lub koob npe nrov hauv kev lag luam hluav taws xob sib tw heev.
Hauv ntej, qhov zoo ntawm granite gantry hauv kev tsim PCB muaj ntau yam. Txij li kev ruaj khov thiab kev nqus dej poob siab mus rau kev ruaj khov thiab kev zoo nkauj, granite gantry yog ib qho khoom muaj nqis rau cov chaw tsim khoom uas nrhiav kev ua tau zoo hauv lawv cov txheej txheem tsim khoom. Raws li qhov kev thov rau cov PCBs zoo txuas ntxiv mus, kev nqis peev hauv granite gantry technology yog ib qho kev txav mus los uas tuaj yeem coj cov txiaj ntsig zoo.
