Thaum cuam tshuam nrog PCB sib dhos, qhov nyuaj tshaj plaws los kwv yees thiab daws tau yog qhov teeb meem ntawm lub zog hluav taws xob luv luv.Tshwj xeeb tshaj yog thaum lub rooj tsavxwm yog ntau nyuaj thiab ntau yam Circuit Court modules tau nce, lub hwj chim mov luv Circuit Court teeb meem ntawm lubPCB sib dhosnyuaj rau tswj.
Txoj kev ntsuas cua sov
Kev tsom xamTaw qhia:
1. Feem ntau, yog tias lub rooj tsavxwm tsis luv luv nrog tin, piv txwv li, cov nti tawg lossis lub capacitor tawg, qhov tsis kam GND feem ntau tsis yog 0Ω, ntau dua lossis tsawg dua, yuav muaj ob peb Ω lossis ob peb feem kaum. ntawm Ω.Siv cov yam ntxwv no, koj tuaj yeem nrhiav tau sai.
2. Siv cov khoom siv hluav taws xob ncaj qha uas tswj tau.Kho qhov hluav taws xob muab hluav taws xob rau qhov hluav taws xob ntawm qhov hluav taws xob luv luv (3.3V luv-circuit rau 3.3V).Teem nws mus rau tam sim no txwv hom, qhov txwv tam sim no tuaj yeem teem rau 500mA, nyob ntawm qhov xwm txheej tiag.
3. Disconnect lub hwj chim mov ntawm lubPCB pawg thawj coj saib, txuas mus rau lub teeb hluav taws xob, thiab pom qhov twg lub rooj tsav xwm hluav taws xob kub, thiab qhov kub kub feem ntau yog luv luv.
4. Txhawm rau saib seb qhov cua sov nyob qhov twg, koj tuaj yeem siv infrared thermal imager los xyuas.Yog tias koj tsis muaj cov duab hluav taws xob infrared, koj tuaj yeem kov ncaj qha nrog koj txhais tes thiab hnov nws (ceev faj tsis txhob hlawv koj tus kheej.
Cov kev ceev faj:
Qhov kev txwv tam sim no ntawm qhov ncaj qha tam sim no yuav tsum tau txiav txim siab raws li qhov xwm txheej tiag tiag.Yog tias qhov kev txwv tam sim no tsawg dhau, qhov cua sov yuav tsis pom tseeb, thiab tsis pom muaj teeb meem.Yog tias qhov kev txwv tam sim no loj dhau lawm, cov xov tooj tooj ntawm PCB yuav raug hlawv.Koj tuaj yeem maj mam kho qhov tam sim no los ntawm me mus rau qhov loj kom txog thaum koj paub tias qhov teeb meem nyob qhov twg.
Nyob rau hauv ib lo lus, Nyob rau hauv tus txheej txheem ntawm kev tshem tawm qhov luv luv Circuit Court ntawm PCB los ua ke fais fab mov, peb yuav tsum tau xyuam xim kom paub thiab daws qhov teeb meem zoo.
PCBFuture tuaj yeem pib ntawmluam tawm Circuit Board manufacturing, los ntawm cov khoom siv thiab kev sib dhos.Peb zoo siab muab cov boards thiab cov khoom siv.Tom qab cov khoom tiav lawm, peb tuaj yeem muab kev kuaj xyuas PCB los xyuas kom meej qhov zoo ntawm PCB.Yog xav paub ntxiv, thov email rauservice@pcbfuture.com.
