Kumenya Kugenzura Impedance Igishushanyo cyibibaho bya PCB

Intangiriro:

Muri iki gihe cyihuta cyane cyikoranabuhanga, igishushanyo cya PCB gifite uruhare runini mugukora neza no kwerekana ibimenyetso neza. Ikintu cyingenzi cyigishushanyo cya PCB kigenzurwa nimbogamizi, bivuga ubushobozi bwo gukomeza guhangana neza mumuzunguruko.Muri iyi blog, turasesengura uburyo bushoboka bwo kugenzura imbogamizi zagenzuwe ku mbaho ​​z’umuzunguruko wa PCB n’uburyo Capel, umuyobozi w’inganda wizewe ufite uburambe bwimyaka 15, akoresha ubuhanga bwayo bukomeye kugirango agere ku bisubizo byiza.

Wige ibijyanye nigishushanyo mbonera cyagenzuwe:

Igishushanyo mbonera cyateganijwe ningirakamaro kubikorwa byihuse kuko byemeza imikorere no kuramba kwibikoresho bya elegitoroniki. Impedance ni ukurwanya umuzenguruko utanga kumasoko asimburana (AC). Ifite uruhare runini muguhuza ibimenyetso biranga ibimenyetso, kugabanya kugoreka ibimenyetso, no gutanga amakuru neza.

Akamaro ko kugenzura ibishushanyo mbonera:

Mubibaho byumuzunguruko wa PCB, gukomeza inzitizi zagenzuwe ningirakamaro mukurinda kwangirika kw'ibimenyetso kubera kudahuza. Iyo inzitizi idacunzwe neza, gutekereza no kugoreka ibimenyetso birashobora kubaho, bigatera ruswa kandi amaherezo bikagira ingaruka kumikorere ya sisitemu yose ya elegitoroniki.

Ubunyangamugayo bwibimenyetso nibyingenzi mubikorwa byihuta nkibigo byamakuru, itumanaho hamwe nibikoresho bya elegitoroniki. Kunanirwa kugera ku mbogamizi zagenzuwe birashobora gutuma igipimo cyamakuru kigabanuka, igipimo cy’amakosa cyiyongera, hamwe n’ibibazo bya EMI, bigira ingaruka ku kwizerwa muri rusange no ku bwiza bw’ibicuruzwa.

Ubuhanga bwo kugenzura inzitizi za Capel:

Hamwe nuburambe bwimyaka 15 mubikorwa byubuyobozi bwumuzunguruko, Capel yabaye umufatanyabikorwa wizewe kubikenewe bya PCB bigoye. Ubuhanga bukomeye bwikigo nubwitange bwo gutanga ubuziranenge budasanzwe byatumye baba abahanga mugushushanya imbogamizi.

Ubumenyi bwuzuye bwa Capel kubijyanye ninganda nka IPC-2221, IPC-2141 na IPC-2251 bibafasha gukora imbaho ​​zumuzunguruko za PCB hitaweho cyane cyane kugenzura inzitizi. Basobanukiwe nubuhanga bwumurongo wogukwirakwiza, ibikoresho bya dielectric, ubugari bwumurongo, intera, nibindi bintu bigira ingaruka kuri impedance.

Uburyo bwa Capel bugenzurwa nuburyo bwo gushushanya:

Kugirango ugere ku gishushanyo mbonera cyagenzuwe, Capel ikoresha ibikoresho bya software bigezweho mu kwigana, gusesengura no kunoza imiterere ya PCB. Ukoresheje porogaramu ya 3D EM yigana, ibikoresho byo gusesengura ibimenyetso byerekana ibimenyetso hamwe na calculatrice ya impedance, Capel iremeza ko ikibaho cyateguwe na PCB cyerekana ibimenyetso biranga inzitizi.

Abashakashatsi ba Capel bafite ubuhanga bakoresha tekinike zitandukanye kugirango bagenzure neza inzitizi. Bashizeho ubwitonzi imirongo yohereza, hitabwa kuburebure, ubugari, na dielectric ihoraho yibikoresho byakoreshejwe. Mubyongeyeho, bakoresha ibice bitandukanye hamwe nimbogamizi zihuye kugirango bagabanye umuhanda kandi barebe neza ibimenyetso byogukwirakwiza.

Ingamba zikomeye zo kugenzura ubuziranenge bwa Capel zirimo ibizamini byimbitse byimbitse mubikorwa byose byakozwe. Bakoresha ibikoresho bisobanutse neza bya TDR (Igihe Domain Reflectometry) kugirango bagenzure indangagaciro kandi bagumane urwego rusabwa.

Ibyiza bya Capel yagenzuye igishushanyo mbonera:

Mugufatanya na Capel kubishushanyo mbonera byateganijwe, abakiriya bunguka inyungu nyinshi zingenzi:

1. Kunoza ibimenyetso byubuziranenge:Ubuhanga bwa Capel butuma ubuziranenge bwibimenyetso bugumaho, bikagabanya ingaruka zo kugoreka ibimenyetso na ruswa.
2. Imikorere myiza:Igenzura risobanutse neza rishobora kongera igipimo cyamakuru, kugabanya igipimo cyamakosa, no kunoza imikorere rusange yibikoresho bya elegitoroniki.
3. Kongera ubwizerwe:Mugukuraho impedance idahuye nibimenyetso byerekana, igishushanyo cya Capel cyongera ibicuruzwa byizewe kandi bigabanya amahirwe yo gutsindwa cyangwa gutsindwa.
4. Kugabanya EMI:Kugenzura neza impedance bifasha kugabanya kwivanga kwa electronique (EMI) no kuzamura EMC (guhuza amashanyarazi).
5. Igihe cyihuse cyo kwisoko:Gukoresha ibikoresho bya software bigezweho hamwe na Capel yoroheje byihutisha igihe gikenewe mugushushanya no gukora PCB, bigatuma ibicuruzwa byihuta.

Mu gusoza:

Igishushanyo mbonera cyateganijwe ni ikintu cyingenzi cyibibaho byumuzunguruko wa PCB kugirango umenye neza ibimenyetso byerekana neza imikorere. Hamwe nuburambe bwimyaka 15 nubuhanga bukomeye, Capel yabaye umufatanyabikorwa winganda wuzuza ubuhanga bwo kuzuza ibisabwa byateganijwe. Ukoresheje ibikoresho bya software bigezweho kandi witonze witonze kuburyo burambuye, Capel ihora itanga ubuziranenge bwa PCB bwujuje ubuziranenge bwo kugenzura inzitizi zikomeye. Izere Capel gukoresha ubuhanga bwabo kugirango uyobore sisitemu ya elegitoronike kugirango ugere ku ntsinzi ukoresheje igishushanyo mbonera cyagenzuwe.
