Hindura uburyo bwiza bwibimenyetso muri 12-PCBs kugirango ugabanye inzira

Gukemura Ibibazo byo Guhuza no Guhuza Inzitizi Mubice 12 byumuzunguruko kugirango ugere ku bwiza bwiza bwibimenyetso no kugabanya Crosstalk

Intangiriro:

Iterambere ryihuse mu ikoranabuhanga ryatumye kwiyongera kw'ibikoresho bikoresha ibikoresho bya elegitoroniki bigoye, bituma hakoreshwa imbaho ​​z'umuzunguruko.Izi mbaho ​​zirimo ibice byinshi byinzira ziyobora, zitanga igisubizo cyoroshye kandi cyiza kuri sisitemu ya elegitoroniki.Ariko, uko bigoye kwizi mbaho ​​byiyongera, havuka ibibazo bitandukanye, nko guhuza inzira no guhuza ibibazo.Muri iyi blog, tuzibira mubibazo byo gukemura ibyo bibazo mubibaho byumuzunguruko wa 12 kugirango tugere ku kayira gato kandi keza cyane.Reka rero twibire!

Sobanukirwa n'ibibazo bya cabling:

Cabling nziza ningirakamaro kugirango ibimenyetso byoroherezwe neza kandi bigabanye kwivanga.Mu kibaho cyumuzunguruko wa 12, imiterere ya denser yerekana uburyo bwongera cyane inzira igoye.Dore ingamba zingenzi zokemura iki kibazo:

1. Shira ibice witonze:

Gutekereza kubigize ibitekerezo bigira uruhare runini mugutezimbere inzira.Mugutegura ibice muburyo bwumvikana, turashobora kugabanya uburebure bwinsinga muri rusange no kugabanya amahirwe yo kunyura.Wibande kugabanya intera iri hagati yingenzi kugirango umenye neza ibimenyetso neza.

2. Koresha ibimenyetso byerekana neza:

Kugenera ingamba zerekana ibimenyetso bifasha kugumana ubuziranenge bwibimenyetso.Kwivanga birashobora kugabanywa muguhuza ibimenyetso bisa hamwe mubice byegeranye kandi bigatanga umwanya uhagije hagati yibimenyetso byoroshye.Byongeye kandi, gukoresha indege nubutaka byimbaraga bifasha kugenzura imiyoboro ya electronique (EMI) no kugabanya ihindagurika rya voltage.

3. Inzira yerekana ibimenyetso:

Ibimenyetso byerekana neza ni urufunguzo rwo gukumira inzira.Koresha ibice bibiri bitandukanye cyangwa bigenzurwa na impedance ibimenyetso byerekana ibimenyetso byinshi.Gushyira mubikorwa tekinike yo gukingira, nko gushyiramo indege zubutaka hagati yikimenyetso, birashobora gutanga urwego rwinyongera rwo kwirinda kurinda urusaku rwinshi.

4. Ibimenyetso byerekana ubunyangamugayo namategeko agenga ibishushanyo:

Gukurikiza ibimenyetso byerekana ubunyangamugayo namategeko agenga ni ngombwa kugirango ugere ku bwiza buhebuje.Kora neza kubara impedance urebye ibiranga substrate nimbogamizi.Menya neza ko guhagarika no guhuza bikwiye kugirango wirinde ibimenyetso byerekana ruswa.

Gukemura ikibazo cyo guhuza ibice:

Usibye gukemura ibibazo, kwemeza guhuza imiyoboro myiza ningirakamaro muburyo bwiza bwo kwerekana ibimenyetso.Reka dushakishe tekinike zimwe na zimwe zo gukemura ikibazo cyo guhuza ibice:

1. Binyuze mu myanya:

Viasiyo ihagaze neza yorohereza ibimenyetso neza gutembera hagati yinzego.Gushyira vias hafi yinkomoko yikimenyetso nicyerekezo bigabanya amahirwe yo kwambukiranya no gutesha agaciro ibimenyetso.Impumyi cyangwa zashyinguwe zirashobora kongera ubuziranenge bwibimenyetso mu kwemerera guhuza ibice byihariye bitinjiye mu kibaho cyose.

2. Kugabanya ukoresheje stubs:

Binyuze kuri stubs birashobora gutera ibimenyetso byiyongera, cyane cyane kumurongo mwinshi.Mugabanye uburebure bwa stubs, turashobora kugabanya ibitekerezo no gutakaza ibimenyetso.Tekinike zitandukanye nka backdrilling na microdrilling zirashobora gufasha gukuraho cyangwa kugabanya uburebure bwa stub.

3. Kugenzura inzira yo gukumira:

Kugera ku mbogamizi zagenzuwe hagati yinzego zinyuranye ni ngombwa mu gukomeza ubunyangamugayo.Kubara inzitizi zikomeye hamwe no kwitondera inzira byitondewe byerekana ibimenyetso biranga impedance ihuza imiyoboro yose ihuza interineti, bigabanya kugoreka ibimenyetso.

4. Igishushanyo mbonera:

Gusuzuma witonze igishushanyo mbonera gishobora kugabanya ibibazo byihuza hagati.Hitamo stackup stackup ukoresheje ibice byabanjirije cyangwa ibice bya dielectric.Hamwe nogukwirakwiza ibikoresho, ibimenyetso byose byanyuze muri buri cyiciro bizagira ibihe bisa, byemeze neza ibimenyetso byerekana neza.

Mu gusoza:

Kwiyongera gukenewe kubikoresho bya elegitoroniki bikora cyane bisaba gukoresha imbaho ​​nyinshi kandi zikomeye.Nyamara, gukemura ibibazo byo guhuza inzira no guhuza ibice muri izi mbaho ​​zigoye ni ngombwa kugirango ugere ku kayira gato kandi keza cyane.Mugushira muburyo bwitondewe ibice, gukoresha ubushishozi gukoresha ibimenyetso byerekana ibimenyetso, gushyira mubikorwa inzira nziza, no gusuzuma uburyo bwiza bwo guhuza imiyoboro, dushobora gutsinda izo mbogamizi kandi tukemeza imikorere myiza kuva kumirongo 12 yumuzunguruko.Koresha izi ngamba kugirango ujyane ibikoresho bya elegitoroniki bigezweho!
