Prototyping PCBs yoroheje ukoresheje Impedance Igenzurwa

Intangiriro:

Mw'isi ya none, aho miniaturizasiya no guhinduka bigenda biba ibintu by'ingenzi mu buhanga bwa elegitoroniki, hakenewe prototyping neza yimbaho ​​zicapye zicapye (PCBs) zifite ibimenyetso bigenzurwa nimbogamizi byiyongereye cyane.Mugihe ibikoresho bya elegitoronike bikomeje kugenda bihinduka, abashushanya bashishikajwe no gushakisha uburyo bushya kandi buhendutse bwo gukora prototype nkiyi PCB.Muri iyi blog, tuzafata ingamba zimbitse muburyo bwo gukora prototyping PCBs zoroshye zifite ibimenyetso bigenzurwa na impedance, dushakisha ibibazo, amahitamo ahari, nibikorwa byiza.

1. Sobanukirwa na PCB yoroheje:

Mbere yo gucukumbura amakuru arambuye ya PCB yoroheje ya prototyping hamwe nibimenyetso bigenzurwa, ni ngombwa gusobanukirwa nibitekerezo nibyiza bya PCB byoroshye.PCB ihindagurika, izwi kandi nka flex circuits, yagenewe kugororwa, kuzingirwa, cyangwa kugoreka kugirango ubike umwanya kandi wongere ubworoherane mubikorwa bitandukanye.Kamere yabo yoroheje, imbaraga nubushobozi bwo guhuza nubutaka butari planari bituma biba byiza mubikorwa nkimodoka, ubuvuzi nindege.

2. Akamaro ko kugenzura inzitizi:

Igenzura ryingirakamaro ningirakamaro mugushushanya imirongo myinshi yumurongo kuko ituma ibimenyetso byerekana ubuziranenge kandi bikagabanya interineti ikora.Muri PCB zoroshye, gukomeza kugenzura inzitizi ningirakamaro cyane kuko mubisanzwe birashobora kwibasirwa no gutakaza ibimenyetso no kugoreka biterwa no kunama cyangwa guhindagurika.Prototyping hamwe nibimenyetso bigenzurwa na impedance birashobora gufasha kwirinda ibibazo nkibi, bikavamo igisubizo cyizewe kandi gikomeye PCB igisubizo.

3. Prototype yoroheje PCB ukoresheje ibimenyetso bigenzurwa na impedance:

Iyo prototyping yoroheje PCBs ifite ibimenyetso bigenzurwa na impedance, abashushanya bafite amahitamo menshi yo gusuzuma.Reka dusuzume uburyo bumwe bukoreshwa:

A. Ikigo cyandika cyumuzunguruko (PCB) Isosiyete ikora prototyping:
Gukorana na societe yumwuga ya PCB yabigize umwuga nuburyo bumwe bwo gukora neza prototype yoroheje PCBs ifite ibimenyetso bigenzurwa na impedance.Izi sosiyete zinzobere zifite ubuhanga, ibikoresho nuburambe bwo gukemura ibibazo bifitanye isano nizunguruka zoroshye.Mugutanga amadosiye akenewe ya dosiye nibisobanuro, abayishushanya barashobora kubona prototypes nziza-nziza hamwe nubugenzuzi bukenewe.

b.Imyandikire y'imbere:
Abashushanya bakunda kugenzura uburyo bwa prototyping barashobora guhitamo gukora prototype yoroheje PCBs murugo.Ubu buryo busaba gushora mubikoresho bikwiye, nka printer ya PCB yoroheje cyangwa umushinga.Ibikoresho bya software bigereranya kandi bigasesengura igenzura, nka Altium Designer cyangwa Eagle, birashobora gufasha kugera kubintu byifuzwa mugihe cya prototyping.

4. Imikorere myiza ya prototyping ya PCB yoroheje ukoresheje ibimenyetso bigenzurwa na impedance:

Kugirango hamenyekane neza igishushanyo mbonera cya PCB cyoroshye kandi gifite ibimenyetso bigenzurwa, inzira nziza igomba gukurikizwa.Dore amabwiriza amwe:

a.Gutegura igishushanyo mbonera:
Mbere yo gutangira prototyping process, abashushanya bagomba gutegura byimazeyo ibishushanyo byabo, harimo stackup layer, ubugari bwumurongo, hamwe nintera kugirango bagere kubyo bifuza kugenzura.Birashobora kuba byiza gukoresha software ishushanya ishyigikira kubara no kwigana.

b.Guhitamo ibikoresho:
Kuri prototypes ya PCB ihindagurika ifite ibimenyetso bigenzurwa na impedance, guhitamo ibikoresho byiza ni ngombwa.Guhitamo substrate yoroheje nka polyimide hamwe no gutakaza ibimenyetso bike hamwe na dielectric itajegajega irashobora kuzamura cyane ibimenyetso byoherejwe hamwe nuburinganire bwibimenyetso muri rusange.

c.Kwemeza no kugerageza:
Nyuma yicyiciro cya prototyping, nibyingenzi kugenzura imikorere no kugenzura ibizamini.Gupima neza guhagarika inzitizi kumurongo ukoresheje ibikoresho byikizamini nkigihe cyagenwe cyerekana (TDR).

Mu gusoza:

Prototyping flex PCBs ukoresheje ibimenyetso bigenzurwa na impedance ntabwo ifite ibibazo byayo, ariko hamwe nubumenyi bukwiye, ibikoresho, nuburyo bukwiye, abashushanya ibintu bashobora kuzana ibishushanyo mbonera bya flex PCB muburyo bushya.Haba gukorana na sosiyete ikora prototyping ya PCB cyangwa gushakisha uburyo bwo guhitamo prototyping murugo, gusobanukirwa n'akamaro ko kugenzura inzitizi no gukurikiza imikorere myiza bizaha inzira ibisubizo byizewe, byoroshye byujuje ibyifuzo byinganda zikoresha ibikoresho bya elegitoroniki.Komeza rero utangire urugendo rwawe rwa prototyping yoroheje PCBs hamwe na trapsed igenzurwa kandi ufungure ibishoboka bitagira iherezo kubikorwa byawe bya elegitoroniki.
