Enqubweni yokufunda i-elekthronikhi, sivame ukubona ibhodi yesekethe ephrintiwe (PCB) kanye ne-Integrated Circuit (IC), iningi labantu lithi "silly ididekile" ngale mibono emibili. Eqinisweni, abayinkimbinkimbi, namuhla sizocacisa umehluko phakathi kwePCB ne-Contentimed Circit.

Yini i-PCB?

Ibhodi Yesekethe Ephrintiwe, eyaziwa nangokuthi ibhodi yesekethe ephrintiwe ngesiShayina, iyingxenye ebalulekile ye-elekthronikhi, umzimba wokusekela wezinto ze-elekthronikhi kanye nenkampani yenethiwekhi yokuxhuma kukagesi kwezinto ze-elekthronikhi. Ngoba yenziwa ngokuphrinta nge-elekthronikhi, ibizwa ngeBhodi Yesekethe "ephrintiwe".

IBhodi Yamanje Yesekethe, ikakhulukazi yakhiwa ngomugqa kanye nendawo (iphethini), ungqimba lwe-dielectric (dielectric), i-hole (nge-solder / i-solsing / isikrini se-welding (selend / ukumaka / ukwelashwa okungaphezulu), njll.

Izinzuzo ze-PCB: Ubuningi obuphezulu, ukuthembeka okuphezulu, ukubonwa, ukuvela, ukuvela, ukuqina, ukuqina.

Yini umjikelezo ohlanganisiwe?

Umjikelezo ohlanganisiwe uyithuluzi le-elekthronikhi elincane noma ingxenye. Kusetshenziswa inqubo ethile, izakhi kanye nokuxhumeka kwe-wiring okufana nama-transistors, aphikisa, ama-capacitors kanye ne-inductures adingekayo esiqeshini esincane noma izingcezu ezimbalwa ze-semicenductor ye-chip noma i-dielectric substrate bese efaka i-schell ukuze abe yimisebenzi ye-micleit. Zonke izakhi zihlanganiswe ngokuhlelekile, zenza izakhi ze-elekthronikhi zibe yisinyathelo esikhulu esiya e-miniaturization, ukusetshenziswa kwamandla okuphansi, ubuhlakani kanye nokuthembela okuphezulu. Imelelwa yincwadi ethi "IC" isendlalelo.

Ngokomsebenzi kanye nokwakheka komjikelezo ohlanganisiwe, kungahlukaniswa ku-Analog okuhlangene, umjikelezo ohlanganisiwe wedijithali kanye ne-digital / analog ehlanganisiwe.

I-Contentied Circtuit inezinzuzo zobukhulu obuncane, engasindi, i-wire ehola kancane, ne-welding point, impilo ende, ukuthembeka okuphezulu, ukusebenza okuhle, njll.

Ubudlelwano phakathi kwe-PCB ne-Contentimed Circtuit.

Umjikelezo ohlanganisiwe ngokuvamile kubizwa ngokuthi ukuhlanganiswa kwe-chip, njengebhodi lomama e-chip laseNorthbridge, i-CPU yangaphakathi, ibizwa nge-Integrated Circuit, igama langempela libizwa nangokuthi i-block ehlanganisiwe. Futhi i-PCB ibhodi yesekethe sivame ukuyiyazi futhi siphrinte kuma-chip we-walding welding.

I-Integrated Circuit (IC) ifakwe ebhodini le-PCB. I-PCB Board ngumthwali wesifunda esihlanganisiwe (IC).

Ngamagama alula, umjikelezo ohlanganisiwe uwukujikeleza okujwayelekile okuhlanganiswe ku-chip, okuphelele. Uma selilimele ngaphakathi, i-chip izolimala. I-PCB ingasebenza ngokwayo, futhi izingxenye zingathathelwa indawo uma ziphukile.
