Izinhlobo ezahlukene zamabhodi angawodwa zinamasu ahlukene okufaka izintambo. Lesi sihloko sethula ikakhulukazi izinhlobo ezimbili ze PCB amasu ezintambo.

Thayipha isu elilodwa lesakhiwo se-PCB

1) Izici eziyinhloko zoHlobo loku-1 zimi kanje: imithetho eqinile yobude, imithetho eqinile ye-crosstalk, imithetho ye-topology, imithetho yokuhlukanisa, imithetho eyisisekelo yamandla, njll.

2) Ukucubungula amanethiwekhi abalulekile: ibhasi

Chaza Ikilasi;

Kudingeka ukuhlangabezana nesakhiwo esithile se-topological, stub kanye nezingqinamba zobude baso (isizinda sesikhathi);

Izinhlobo ezimbili zamasu omzila we-PCB

Umdwebo weketango le-daisy elilinganiselwe kanye neketango le-daisy ledrayivu eliphakathi

Setha izikhonkwane ezibonakalayo ukuze ulawule i-topology;

Izinhlobo ezimbili zamasu omzila we-PCB

I-Virtual T point diagram

Nciphisa i-STUB. Setha ubude be-stub obukhulu, ukubambezeleka/ubude kufanele bunikezwe ububanzi; kuvinjelwe ukuphuma ohlangothini olude lwe-pad; kuvunyelwe ukuthi kube nokuhlangana kutheminali.

3) Ukucutshungulwa kwenethiwekhi ebalulekile: umugqa wewashi

Chaza Ikilasi, setha isikhala esanele somugqa noma isikhala phakathi kwekilasi nekilasi;

Setha umugqa wewashi kungqimba oluthile nendawo.

4) Ukucutshungulwa kwenethiwekhi eyisihluthulelo: umugqa ohlukile

Ngokuvamile kudingeka ucacise ungqimba lwezintambo;

Sebenzisa imodi ehambisanayo, gwema imodi ye-tandem;

Chaza ubude bokumadaniswa kwemigqa emibili ehlukene kanye nokumadaniswa kobude bamapheya ahlukene;

Indlela evamile yokusetha isikhala phakathi kwamapheya emigqa ehlukile iwukuchaza ukubhanqwa kokuhlukanisa njengeklasi, bese uchaza isikhala phakathi kwekilasi nekilasi.

5) Ukulawulwa kwe-Crosstalk

Kumele kube nokuvunyelwa okwanele phakathi kwamaqembu enethiwekhi; isibonelo, kufanele kube nemingcele yesikhala phakathi kwemigqa yedatha, imigqa yekheli nelayini yokulawula, misa lawa manethiwekhi abe esigabeni esihambelanayo, bese phakathi komugqa wedatha nolayini wekheli, ulayini wedatha nolayini wokulawula Setha imithetho yokulawula i-crosstalk phakathi imigqa, phakathi kwemigqa yekheli nemigqa yokulawula.

6) Isihlangu

Izindlela zokuvikela: i-parallel (i-parallel), i-coaxial (i-coaxial), i-cascade (i-tandem);

Ngemuva kokuthi imithetho isethiwe, ungasebenzisa i-wiring manual noma othomathikhi.

Izinhlobo ezimbili zamasu omzila we-PCB

Thayipha isu lesakhiwo se-PCB engu-2

I-1) Idizayini yohlobo 2 ye-PCB inakho kokubili izinselele zokubona ngokomzimba kanye nezinselele zokutholwa kwemithetho kagesi.

I-2) “Umhlahlandlela” uyadingeka ngesikhathi senqubo yokufaka izintambo, njengokuthi: I-Fanout, ukuhlukaniswa kwezingqimba, ukulawulwa kwenqubo ye-wiring ezenzakalelayo, incazelo yendawo engavunyelwe, ukulandelana kwezintambo, njll, kudingeka kuphazamiseke kahle.

3) Hlola futhi uhlaziye ukuthi kungenzeka yini ukufaka izintambo;

4) Cabangela ukufezeka kwemithetho yenyama kuqala, bese kuba ukugcwaliseka kwemithetho kagesi;

5) Ngokungqubuzana noma amaphutha, kuyadingeka ukuthi kuhlaziywe kabanzi izimbangela futhi kulungiswe isu lezintambo ngendlela eqondisiwe.

Konjiniyela be-PCB, isu lezintambo ze-PCB liwulwazi olubalulekile, futhi wonke umuntu kufanele abe nekhono kulo.
