Soldering Station Failure Analysis
1. Tus kov tsis yog lawm (yog tias nws zoo ib yam, nws tuaj yeem txiav tawm)
2. Nrog rau qhov qhib Circuit Court ntawm tus kov sensor (thermocouple lossis thermal resistance) (tus kov tshiab tshem tawm qhov teeb meem no)
3. Cov kab lis kev cai tsis raug (tus kov tshiab tuaj yeem tshem tawm qhov teeb meem no)
4. Soldering chaw nres tsheb daws teeb meem lub qhov (socket), kev sib cuag tsis zoo los yog virtual vuam hlau
5. Circuit Board teeb meem. Muaj ntau yam sensor ua circuits, tab sis lub hauv paus ntsiab lus yog tib yam
(Qhov tseem ceeb, op amp (358 lossis op07, thiab lwm yam) ua kom lub teeb liab sensor rau lub microcontroller, thiab tom qab ntawd lub microcontroller qhia qhov ntsuas kub *S_E op amp tso zis ntau dua 1.5V *) Qee qhov op amps yog powered los ntawm ob lub zog khoom siv
(1) Qhov tsis muaj lub zog tsis zoo yuav ua rau muaj qhov xwm txheej zoo li no
(2) Lub op amp yuav puas.
(3) Lub peripheral tsis kam ntawm op amp yog tawg
(4) Qhov kev siv ntawm ib leeg-chip microcomputer tsis zoo (feem ntau 2.5V thiab 5V)
Thaum siv hluav taws xob soldering hlau, siv qhov chaw nres tsheb soldering, qhov chaw nres tsheb yog dab tsi
Lub chaw nres tsheb soldering yog ib qho cuab yeej siv tes uas feem ntau siv hauv cov txheej txheem hluav taws xob hluav taws xob uas ua rau ob lub workpieces melts los ntawm kev siv cua sov rau lub solder (feem ntau yog tin hlau). Soldering chaw nres tsheb yog siv nyob rau hauv ib tug ntau yam ntawm daim ntaub ntawv, xws li los ntawm cov khoom siv hluav taws xob kho rau hluav taws xob integrated circuits thiab chips. Soldering chaw nres tsheb yog siv los ua cov cuab yeej vuam, tab sis lawv feem ntau yog siv rau soldering ntawm PCB Circuit Court boards hauv electronics factories.
Cov haujlwm ntawm qhov chaw nres tsheb soldering yog:
a. Anti-static muaj nuj nqi: feem ntau yog los tiv thaiv qhov precision nti vuam los ntawm kev tawg los ntawm hluav taws xob zoo li qub.
b. Pw tsaug zog muaj nuj nqi: lub zog txuag, prolonging lub neej ntawm lub soldering hlau taub.
c. Digital zaub kub: yooj yim kho.
d. Tus password ntsuas kub: tiv thaiv cov neeg ua haujlwm los ntawm kev hloov qhov kub thiab txias ntawm qhov xav tau.
