Umbuzo: Uyazi ukuthi imikhiqizo ye-pcba ingagcinwa isikhathi esingakanani?

Sibiza ibhodi izingxenye ezihlukahlukene ashiselwe ebusweni ephrintiwe wesifunda ibhodi PCBA, kanye nokuthuthukiswa kwesayensi nobuchwepheshe, abantu sebeqalile ukunaka kakhudlwana isikhathi ukusetshenziswa PCBA wesifunda ibhodi kanye nokwethenjelwa imvamisa high ukusebenza, bese i-PCBA iphinde inake kakhulu impilo yayo yokugcina. Ngaphansi kwezimo ezijwayelekile, umkhawulo wesikhathi sokugcina we-PCBA uyiminyaka emi-2 kuye kweyi-10, futhi namuhla sizokhuluma ngezici ezinethonya zomjikelezo wesitoreji wamabhodi aqediwe we-PCBA.

Izinto ezithinta umjikelezo wesitoreji sebhodi eliqediwe le-PCBA

01 Imvelo

Imvelo emanzi futhi enothuli ngokusobala ayihambisani nokulondolozwa kwe-PCBA. Lezi zici zizosheshisa i-oxidation kanye nokonakala kwe-PCBA futhi zifinyeze impilo yeshelufu ye-PCBA. Ngokuvamile, kunconywa ukugcina i-PCBA endaweni eyomile, engenalo izintuli, izinga lokushisa elingaguquki elingu-25 ° C.

2 Ukwethembeka kwezingxenye

Ukuthembeka kwezingxenye ku-PCBA ehlukene futhi kunquma kakhulu impilo yokugcina ye-PCBA, ukusetshenziswa kwezinto eziphezulu kanye nezinqubo zezingxenye zinamandla okumelana nezindawo ezinokhahlo, ikhono layo lokuhlukahluka okubanzi, ukumelana ne-oxidation enamandla, okubuye kunikeze isiqinisekiso. ukuzinza kwe-PCBA.

3. Inqubo yokwelapha yezinto ezibonakalayo nephezulu yebhodi lesifunda eliphrintiwe

Impahla yebhodi yesifunda ephrintiwe ngokwayo ayithinteki kalula emvelweni, kodwa inqubo yayo yokwelashwa kwendawo ithinteke kakhulu nge-oxidation yomoya. Ukwelashwa okuhle kwendawo kunganweba impilo yeshalofu ye-PCBA.

4 PCBA egijima umthwalo

Umthwalo womsebenzi we-PCBA uyisici esibaluleke kakhulu ekuphileni kwayo. Imvamisa ephezulu kanye nokusebenza komthwalo ophezulu kuzoba nomthelela omkhulu oqhubekayo emigqeni yebhodi lesifunda kanye nezingxenye, futhi kulula ukugcwalisa i-oxidize ngaphansi kwethonya lokushisa, okuholela kumjikelezo omfushane kanye nesifunda esivulekile ngesikhathi sokusebenza isikhathi eside. Ngakho-ke, amapharamitha okusebenza ebhodi le-PCBA kufanele abe phakathi nendawo ukuze agweme ukusondela enanini eliphakeme, ukuze avikele ngempumelelo i-PCBA futhi andise impilo yayo yokugcina.
