Ungaqinisekisa kanjani futhi uhlaziye isekethe ye-PCB yomhlangano kagesi omfushane?

Lapho usebenzelana nomhlangano we-PCB, okunzima kakhulu ukubikezela nokuxazulula inkinga yokunikezwa kwamandla kagesi.Ikakhulukazi lapho ibhodi liyinkimbinkimbi futhi amamojula wesifunda ahlukahlukene ayanda, inkinga yesifunda esifushane yokuphakelwa kwamandla kagesiUkuhlanganiswa kwe-PCBkunzima ukulawula.

Indlela yokuhlaziya ukushisa

UkuhlaziyaIsingeniso:

1. Ngokuvamile, uma ibhodi lingafinyezwanga nge-tin, isibonelo, i-chip iphukile noma i-capacitor iphukile, ukumelana ne-GND ngokuvamile akuyona i-0Ω, ngaphezulu noma ngaphansi, kuzoba ne-Ω embalwa noma okweshumi okumbalwa. kwe Ω.Ngokusebenzisa lesi sici, ungathola ngokushesha .

2. Sebenzisa ugesi olawulwayo oqondile wamanje.Lungisa i-voltage yokuphakela amandla ku-voltage kagesi wesiyingi esifushane (3.3V i-short-circuit ukuya ku-3.3V).Ibeke kumodi yamanje yokukhawulela, umkhawulo wamanje ungasethwa ku-500mA, kuye ngesimo sangempela.

3. Nqamula ukunikezwa kwamandla kagesiIbhodi lomhlangano le-PCB, xhuma ekunikezeni amandla okusethiwe, futhi ubone lapho ibhodi lesifunda lishisa khona, futhi lapho kushisa khona kuvame ukuba yisifunda esifushane.

4. Ukuze ubone ukuthi ukushisa kuphi, ungasebenzisa isithwebuli se-infrared thermal ukuze uhlole.Uma ungenaso isithombe se-infrared thermal, ungakwazi ukusithinta ngokuqondile ngezandla zakho futhi usizwe (qaphela ukuthi ungazishisi.

Izinyathelo zokuzivikela:

Umkhawulo wokulungiselelwa kwamanje komthombo wamanje oqondile udinga ukunqunywa ngokuya ngesimo sangempela.Uma ukulungiselelwa komkhawulo wamanje kukuncane kakhulu, ukushisa ngeke kubonakale, futhi ayikho inkinga engatholakala.Uma ukulungiselelwa komkhawulo kwamanje kukukhulu kakhulu, izintambo zethusi ku-PCB zingashiswa.Ungalungisa i-current kancane kancane usuka kwencane uye enkulu uze wazi ukuthi inkinga ilele kuphi.

Ngamafuphi, Enqubweni yokuqeda isifunda esifushane sokuphakelwa kwamandla komhlangano we-PCB, kufanele sinake ukuze sithole futhi sixazulule inkinga ngempumelelo.

I-PCBFuture ingaqala ngoukukhiqizwa kwebhodi lesifunda eliphrintiwe, ukuya ekuhlinzekeni kwezingxenye kanye nokuhlanganisa.Siyajabula ukuhlinzeka ngamabhodi nezingxenye.Ngemuva kokuthi ukukhiqizwa sekuqediwe, singahlinzeka ngokuhlolwa kwe-PCB okuqeqeshiwe ukuze siqinisekise ikhwalithi ye-PCB.Ukuze uthole ulwazi olwengeziwe, sicela usithumele i-imeyili kuservice@pcbfuture.com.
