PCB indlela yokucubungula izintambo

Emaceleni amabili PCB board, lapho uxhumano lweqile, izintambo ezinhle nezimbi zingasetshenziswa ukuxazulula. Ekudizayineleni ibhodi lesifunda elenziwe ngohlangothi olulodwa, eminye imigqa ayikwazi ukuxhumeka, imvamisa isebenzisa i-jumper wiring, kwabaqalayo, i-jumper wiring ivame ukulamula, yinde futhi imfishane, okuzoletha ukuphazamiseka ekukhiqizeni. Lapho ufaka izintambo zejumper, uma uhlobo lincane, kungcono, imvamisa kusethwa kuphela u-6mm, 8mm, 10mm amathathu, ngaphesheya kwalolu hlu kuzoletha ukuphazamiseka ekukhiqizeni. Ngaphezu kwalokho, izindlela ezilandelayo zingasetshenziswa ukwenza izintambo ziwele ukufeza indima ye-jumper wiring.

1, Faka umugqa wokuwela noma ukumelana no-zero ohmic. Ixhunywe ngocingo ebhodini lesifunda ibizwa ngokuthi i-cross line, ibhodi lesifunda elifanayo uma ubude bomugqa wesiphambano bungafani kuzothinta ukubukeka, ubude bomugqa wokuwela nezinto ezincane (njengokumelana) okungaguquguquki kangcono. Uma ukufakwa kokumelana no-zero ohmic kuhlanzekile, ukuze abantu bangazizwa ukuthi kukhona umugqa ophambene.
2. Indlela yokufaka esikhundleni sento. Isibonelo, uma ucingo lwesiphambano luxhunywe ochungechungeni nge-18K ω resistor, ukumelana manje sekushintshelwe ku-15K ω, futhi kufakwa i-resistor engu-3K at ocingweni lwesiphambano. Inani eliphelele lisekhona ngo-18K ω, futhi ucingo lwesiphambano lukhanseliwe.
3, ukuphrinta ngaphesheya komugqa. Iphaneli elilodwa kanye nomugqa wesiphambano wokuphrinta ungabonakala ngemuva kokuwela kokuxhumeka, kepha izindleko zokukhiqiza zebhodi lokuphrinta zizobe ziphakeme kancane.
I-4, i-labyrinth wiring, ngejubane eliphansi lesekethe yedijithali, ukuze ikwazi ukufaka ucingo endaweni efanayo yebhodi, ingasebenzisa indlela yezintambo ze-labyrinth kaningi emabangeni amabili emigodi isondele kakhulu phakathi kwe-shuttle ehlanganisiwe ye-solder. Ngenxa yobukhulu bomugqa ophakeme nobubanzi bolayini obuncane, inani lebhodi lesifunda liyadingeka ukuthi likhulu ngokuqhathaniswa.
