Yuav ua li cas tseem ceeb PCB tsim rau SMT mounting txheej txheem?

Ua ntej peb yuav piav qhia txog peb lub ntsiab lus, uas yog, qhov tseem ceeb ntawm PCB tsim yog li cas rau cov txheej txheem SMT thaj.Hauv kev txuas nrog cov ntsiab lus uas peb tau txheeb xyuas ua ntej, peb tuaj yeem pom tias feem ntau ntawm cov teeb meem zoo hauv SMT yog ncaj qha ntsig txog cov teeb meem ntawm cov txheej txheem pem hauv ntej.Nws zoo ib yam li lub tswv yim ntawm "deformation zone" peb muab tso rau niaj hnub no.

Qhov no feem ntau yog rau PCB.Ntev npaum li qhov hauv qab ntawm PCB yog khoov los yog tsis sib xws, PCB tuaj yeem khoov thaum lub sijhawm ntsia hlau ntsia.Yog tias ob peb qhov sib law liag tau muab faib rau hauv ib txoj kab lossis ze rau tib thaj chaw tshawb fawb, PCB yuav khoov thiab deformed vim qhov rov ua haujlwm ntawm kev ntxhov siab thaum lub sij hawm tswj cov txheej txheem ntsia hlau.Peb hu qhov no rov khoov cheeb tsam thaj tsam deformation.

Yog hais tias lub nti capacitors, BGAs, modules, thiab lwm yam kev ntxhov siab hloov rhiab Cheebtsam yog muab tso rau hauv lub deformation cheeb tsam thaum lub sij hawm muab tso rau txheej txheem, ces ib tug solder sib koom yuav tsis tawg los yog tawg.

Qhov tawg ntawm lub module fais fab mov solder sib koom nyob rau hauv cov ntaub ntawv no yog ntawm qhov teeb meem no

(1) Tsis txhob tso cov khoom siv rau hauv qhov chaw uas yooj yim rau khoov thiab deform thaum lub sij hawm sib dhos PCB.

(2) Siv cov cuab yeej hauv qab hauv qab thaum lub sijhawm sib dhos ua kom lub PCB tiaj tus qhov ntsia hlau ntsia kom tsis txhob khoov ntawm PCB thaum sib dhos.

(3) Txhim kho cov pob qij txha.
