PCB muchinjika-wiring kugadzira nzira

Mune maviri-mativi PCB bhodhi, kana iko kubatana kwayambuka, yakanaka uye isina kunaka wiring inogona kushandiswa kugadzirisa. Mune imwechete-mativi edunhu bhodhi dhizaini, mimwe mitsara haigone kubatanidzwa, kazhinji kushandisa jumper wiring, muvatanga, jumper wiring inowanzo kuve inopokana, yakareba uye ipfupi, izvo zvinounza kusagadzikana mukugadzirwa. Paunenge uchiisa jumper wiring, iyo shoma mhando, iri nani, kazhinji inongogadzika 6mm, 8mm, 10mm matatu, kupfuura iyi renji ichaunza kusagadzikana mukugadzirwa. Uye zvakare, nzira dzinotevera dzinogona kushandiswa kugadzira waya dzekuyambuka kuti dziite basa rejumper wiring.

1, Wedzera muchinjikwa mutsetse kana zero ohmic kuramba. Yakabatanidzwa netambo mubhodhi redunhu inonzi muchinjikwa mutsetse, iwo iwo wedunhu bhodhi kana kureba kwemuchinjikwa mutsetse kusiri yunifomu kunokanganisa kuoneka, kuyambuka mutsetse kureba uye zvidiki zvidimbu (sekushora) zvinowirirana zvirinani. Kana kuiswa kwe zero ohmic kuramba kuri kuchena, kuitira kuti vanhu vasanzwe kuvepo kwechinjikwa mutsetse.
2. Chinhu chinotsiva nzira. Semuenzaniso, kana muchinjikwa waya wakabatana mune dzakateedzana ne18K-resistor, iko kuramba iko iko kwashandurwa kuita 15K ω, uye 3K-resistor yakaiswa pamuchinjikwa waya. Iko kukosha kwese kuchiri 18K ω, uye waya wepamuchinjikwa wakanzurwa.
3, kudhinda pamutsetse. Imwe chete pani pamwe nekudhinda muchinjikwa mutsetse unogona kuitika mushure mekubatana muchinjikwa, asi iyo yekudhinda bhodhi kugadzira mutengo ichave yakati rebei.
4, labyrinth wiring, mune yakachimbidzika dhijitari wedunhu, kuti ukwanise kuisa waya pane imwechete bhodhi pamusoro, inogona kushandisa labyrinth wiring nzira kazhinji mumativi maviri egomba iri padyo chaizvo pakati peiyo solder yekubatanidza shuttle. Nekuda kwehurefu hwemutsara uye yakatetepa mutsetse upamhi, chikamu chebhodhi redunhu chinodiwa kuve chakakura.
