Cov ncauj lus kom ntxaws piav qhia ntawm kev kho cov kauj ruam rau ntau txheej txheej txheem hluav taws xob:
1, Pom Kev Kuaj
Ua ntej nqa tawm ntau txheej txheem bircuit Court board, kev pom kev pom yog thawj zaug uas yuav tsum tau ua tiav rau cov Circuite lub cev, xws li hlawv, tawg, lossis xeb. Yog tias pom cov teeb meem no, lawv yuav tsum tau kho lossis hloov kom raws sijhawm.
2, huv cov hmoov av
Siv daim ntaub dawb-dawb thiab lwm yam cuab yeej los ntxuav cov hmoov av ntawm cov pob zeb pcb Circuit Court Circuit Court kom tsis txhob muaj teeb meem xws li luv luv hluav taws xob lossis cov neeg tsis zoo. Xyuam xim tsis txhob siv cov cuab yeej muaj hluav taws xob zoo li lub sijhawm tu kom tsis txhob muaj kev puas tsuaj rau cov kev puas tsuaj rau cov Circuit Court.
3, Ntsuas Hluav Taws Xob
Siv cov tshuaj ntsuam sib xyaw lossis cov kev ntsuas kev sim ntsuas cov khoom siv luv luv, qhib kev sib tw, lossis cov kev sib txuas tsis zoo, lossis cov kev sib txuas tsis zoo, lossis cov kev sib txuas tsis zoo, lossis cov kev sib txuas tsis zoo, lossis cov kev sib txuas tsis zoo, lossis kev sib txuas tsis zoo. Nws muaj peev xwm sim ntsuas cov ntsiab lus xws li voltage thiab tam sim no los txiav txim siab qhov txhaum taw tes. Lub sijhawm kuaj, nws yog ib qho tseem ceeb kom them sai sai rau kev nyab xeeb thiab zam kev phom sij xws li hluav taws xob.
4, ntsuas teeb liab
Rau cov teeb meem nyuaj ntxiv, nws yuav tsim nyog los siv tus oscilloscope lossis cov ntsuas hluav taws xob los kuaj xyuas kev ncaj ncees thiab sijhawm ntawm lub teeb liab. Kev tsom teeb liab tuaj yeem txiav txim siab ntau dua qhov txhaum plaub rau kev kho.
5, kho puas
Yog tias muaj cov khoom siv puas ntsoog lossis cov voj voog ntawm cov txheej txheej pcb multi-pcb Circuit Court, lawv yuav tsum tau kho lossis hloov. Cov cuab yeej siv tshuaj uas siv tau rau kev kho, lossis hnyav hloov vuam tam sim no. Yog tias ib qho kev sib xyaw ua ke ntawm Circuit Courcuit board yog puas thiab xav tau hloov, nws tuaj yeem hloov kho, nws tuaj yeem cuam tshuam BGA (pob daim phiaj lossis lwm yam kev ntaus suab. Thaum cov hlau tawg lossis kev puas tsuaj, kev kho cov hlau kho tau tuaj yeem siv los rov tsim cov kev txuas no.
6, khij lub zog
Yog tias cov txheej txheej pcb multi-pcb yuav tsum tau muab hluav taws xob sab nraud, nws yog qhov tsim nyog los tshuaj xyuas seb lub zog hluav taws xob puas yog ib txwm muaj. Tuaj yeem sim seb qhov voltage thiab tam sim no ntawm lub zog muab tau raws li qhov yuav tsum tau ua. Thaum kuaj xyuas lub zog mov, nws yog ib qho tsim nyog kom them sai sai rau kev nyab xeeb thiab zam kev phom sij xws li hluav taws xob ua hluav taws xob zoo li hluav taws xob.
7, debugging
Tom qab ua tiav cov kev kho, kev debugging yog qhov yuav tsum tau ua kom ntseeg tau tias ntau-txheej pcb Circuit Court Board tuaj yeem ua haujlwm tau zoo. Kev debugging cov cuab yeej tuaj yeem siv rau debugging. Thaum debugging, nws yog ib qho tseem ceeb kom them sai sai rau kev nyab xeeb thiab zam rau kev puas tsuaj theem nrab rau ntawm Circuit Court Board.
Hauv cov ntsiab lus, thaum daws teeb meem thiab kho ntau txheej pcb Circuit Coffic Cam, nws yog qhov tsim nyog los siv cov cuab yeej tshaj lij thiab kev txawj ntse. Yog tias koj tsis muaj kev paub lossis kev txawj, nws raug pom zoo kom nrhiav kev pab los ntawm cov kws tshaj lij. Nyob rau tib lub sijhawm, nws tseem yog qhov tseem ceeb rau kev tswj cov kev tiv thaiv kom tsim nyog, kom tiv thaiv kev puas tsuaj rau cov kev puas tsuaj rau cov hluav taws xob los ntawm overheating.
