Dareenka guud iyo qaababka kormeerka PCB: fiiri, dhagayso, urta, taabashada ...

1. Waa la mamnuucay in la isticmaalo qalabka tijaabada dhulka ah si loo taabto TV-ga nool, maqalka, fiidiyowga iyo qalabka kale ee saxanka salka si loo tijaabiyo golaha PCB iyada oo aan la socon

Waa mamnuuc in si toos ah loo tijaabiyo TV-ga, maqalka, fiidiyowga iyo aaladaha kale iyadoon loo adeegsanin isbadalka awoodda ee qalabka iyo aaladda ay ku jiraan qolofyo saqaf ah. In kasta oo raadiyaha guud iyo caqabadaha ay leeyihiin beddelaad koronto, markii aad la xiriirto telefishanka khaaska ah ama aalad aad u sahlana, taas oo ah in lagu soo oogo wareegga korantada, taas oo saameysa wareegga korantada, taas oo keenaysa ballaarinta isku dhafka ah ee qaladka.

2. U fiirso waxqabadka dahabka ee birta lagu iibiyo markaad tijaabinayso guddiga PCB

Looma oggola inuu u isticmaalo birta iibinta iibinta si loo helo awood. Hubso in birta iibinta aan lagu soo oogin. Waxaa ugu wanaagsan in la saleeyo qolofta birta toogashada. Ka taxaddar wareegga xaafadaha. Waxay aamin u tahay in la isticmaalo bir aad u yar oo toogasho ah oo ah 6 ~ 8V.

3. Ogow mabda'a shaqo ee wareegga isku-dhafan ee isku-dhafan iyo wareegyada la xiriira ka hor intaadan tijaabin looxyada PCB

Kahor baarista iyo hagaajinta wareejinta isku dhafan, marka hore waa inaad barataa shaqada isku-dhafka isku dhafan ee la isticmaalay, wareegga korantada, doorka pin-ka ee caadiga ah, mabaadiidka shaqada ee PIN, mabaadiida shaqada ee ka kooban qaybaha durugsan. Haddii xaaladaha kor ku xusan la buuxiyo, falanqaynta iyo kormeerka ayaa aad u fudud.

4. Ha u keenin wareegyo gaaban oo u dhexeeya biinanka markii aad tijaabinayso PCB

Marka la cabbirayo korantada ama tijaabinta mawjadaha mawjadda leh baaritaanka oscilloscope-ka, ha u keenin wareegga gaagaaban ee u dhexeeya biinanka wareegga isku-dhafka ah sababo la xiriira is-riixitaanka macdanta tijaabada ama tijaabada. Waxaa ugu wanaagsan in lagu cabbiro wareegga wareejinta ee la daabacay ee tooska ah ee ku xiran biinanka. Wareeg kasta oo gaagaaban oo si fudud u dhaawici kara wareegga isku dhafan, sidaa darteed taxaddar badan marka aad tijaabinayso xirmada isku-darka isku-dhafka ah ee isku-dhafka ah

5. Iidajiifka gudaha ee qalabka tijaabada PCB ee PCB waa inuu ahaadaa mid weyn

Markii lagu cabirayo korantada DC ee biinanka IC, musiibo leh caabbinta gudaha ee madaxa mitirka ka weyn 20kω / v waxaa jira khalad cabbir ballaaran oo loogu talagalay korantada biinanka qaarkood.

6. U fiirso kululaynta kuleylka ee korantada isku-dhafka ah ee isku dhafan marka aad tijaabinayso boodhka PCB

Awoodda wareegga isku dhafan waa inay si fiican u dishaa kuleylka, loomana oggola in lagu shaqeeyo awood sare iyada oo aan kuleylka lahayn.

7. Xariiqda hogaanka ee hogaaminta ee guddiga PCB waa inay macquul ahaadaan

Haddii aad u baahan tahay inaad ku darto qaybaha dibedda ah si aad ugu dajiso qaybta waxyeelada leh ee wareegga isku dhafan, qaybaha yar yar waa in la istcimaalaa, gaar ahaan salka udhaxeeya ee u dhexeeya wareegga power commur comiclusier-ka ee isku-dhafka ah iyo dhamaadka wareegga.

8. Hubi guddiga PCB si aad u hubiso tayada alxanka

Markii loo adeego, iibiyaha waa shirkad, oo uruurinta iibinta iyo pores waxay si fudud u horseedi karaan iibin been abuur ah. Waqtiga iibinta guud ahaan ma aha wax ka badan 3 ilbiriqsi, iyo awoodda birta birta waa inay noqotaa 25w kuleylka gudaha ah. Wareegtada isku dhafan ee la soo kacay waa in si taxaddar leh loo hubiyaa. Waxaa ugu wanaagsan in la isticmaalo ohmmeter si loo cabbiro inuu jiro wareegga gaagaaban ee u dhexeeya biinanka, waxay xaqiijinayaan inaysan jirin cufnaanta gacanta, ka dibna u roga korantada.
9. Si fudud ha u go'aamin burburka wareegga isku dhafan markaad tijaabineyso guddiga PCB

Ha xukumin in wareegga isku dhafan uu si fudud u waxyeeleeyo. Sababta oo ah isku-darka isku dhafka ah ee isku dhafan ayaa si toos ah loo soo koobay, mar ay tahay marxalad aan caadi ahayn, waxay sababi kartaa isbeddelo koronto oo badan, isbedeladaasna daruuri uma ahan burburka wareegga isku dhafan. Intaas waxaa sii dheer, xaaladaha qaarkood, korantada oo la cabiray ee PIN kasta ayaa ka duwan kan caadiga ah marka qiyamku uu iswaafajiyo ama uu had iyo jeer u jeedo had iyo jeer micnaheedu maahan in wareegga isku-dhafan uu fiican yahay. Sababtoo ah ciladaha jilicsan qaarkood ma sababi doonaan isbedelo ku dhaca korantada DC.

Habka PCB ee PCK

Loogu talagalay guddiga cusub ee PCB ee dib loo soo celiyay, waa inaan marka hore fiirsanaano in ay jiraan wax dhibaatooyin ah oo ku saabsan guddiga, sida in ay jiraan dillaacyo cad, sida loo baahan yahay, iwm. Haddii loo baahdo, hubi in caabbinta u dhexeeya korantada iyo dhulka ay ku filan yihiin.

Loogu talagalay guddi wareeg ah oo cusub oo loo qaabeeyey, oo badanaa la kulma qaar ka mid ah dhibaatooyinka qaarkood, gaar ahaan marka guddigu aad u weyn yahay oo ay jiraan waxyaabo badan oo aan macquul aheyn in la bilaabo. Laakiin haddii aad sahamineyso noocyo habab macquul ah oo macquul ah, dib-u-dejintu waxay dhalinaysaa laba jeer natiijada karta dadaalka.

PCB PONGED TALOOYINKA:

1. Loogu talagalay guddiga cusub ee PCB ee dib loo soo celiyay, waa inaan marka hore fiirinnaa haddii ay jiraan wax dhibaatooyin ah oo ku saabsan guddiga, sida loo baahan yahay, iwm. Haddii loo baahdo, waxaad hubin kartaa in caabbinta u dhexeeya korantada iyo dhulka ay ku filan yihiin.

2. Kadibna qaybaha ayaa la rakibay. Moodooyinka madaxa-bannaan, haddii aadan hubin inay sifiican u shaqeeyaan, waxaa ugufiican in aan la rakibin dhammaantood, laakiin ku rakib qayb qayb ahaan ah hal mar, si ay u fududaato go'aaminta caqabadda. Markaad dhibaatooyin la kulanto, ma bilaabi kartid.

Guud ahaan marka loo eego, waxaad ku rakibi kartaa sahayda korantada marka hore, ka dibna awood u yeelo inaad hubiso bal in korantada korantada ee korantada ay caadi tahay. Haddii aadan haysan kalsooni badan marka aad koraynayso (xitaa haddii aad hubto, waxaa lagugula talinayaa inaad ku darto fiyuus, kaliya haddiiba), tixgeli inaad isticmaasho korantada si habsami leh oo lagu habeyn karo oo leh howsha xaddidaadda hadda jira.

Waxay sii daayaan ilaalinta xad dhaafka ah ee hadda jirta, ka dibna si tartiib ah u kordhi qiimaha korantada ee korantada xakameysan, oo ay la socoto galka hadalka, galka korantada iyo korantada wax soo saarka. Haddii uusan jirin ilaalin xad dhaaf ah iyo dhibaatooyin kale inta lagu gudajiro hagaajinta kore, iyo korantada soosaarka ay gaareen caadi, korantada waa hagaag. Haddii kale, ka goynta korantada, hel qaladaadka barta, kuna celi tallaabooyinka kor ku xusan ilaa korantada ay caadi tahay.

3. Marka xigta, ku rakib cutubyo kale si tartiib tartiib ah. Waqti kasta oo cutubku rakiban yahay, awood ku bixi oo tijaabiso. Markii la korayo, raac tillaabooyinka kor ku xusan si aad uga fogaato hadda-hadda ee ay sababtay khaladaadka naqshadeynta iyo / ama khaladaadka rakibaadda iyo gubashada qaybaha.
