Umehluko Phakathi Kwe-Pad Ne-Via

1. Izincazelo Ziyehluka

I-Pad: iyunithi eyisisekelo yomhlangano we-surface mount, esetshenziselwa ukwakha i-landpattern yebhodi lesifunda, okungukuthi, inhlanganisela yezinhlanganisela zamaphedi eziklanyelwe izinhlobo zezingxenye ezikhethekile.

Ngembobo: ngokusebenzisa imbobo ibizwa nangokuthi i-metalization hole.Kuphaneli ekabili kanye ne-PCB ye-multilayer, imbobo evamile ibhojwa lapho kuhlangana khona izintambo ezidinga ukuxhunywa phakathi kwezendlalelo ukuze kuxhunywe izintambo eziphrintiwe phakathi kwezingqimba.Imingcele eyinhloko yembobo ububanzi obungaphandle bembobo kanye nobukhulu bomgodi.

Imbobo ngokwayo ine-capacitance ye-parasitic kanye ne-inductance phansi, okuvame ukuletha umphumela omubi omkhulu kumklamo wesifunda.

2. Izimiso Ezihlukene

Iphedi: Uma isakhiwo sephedi singakhiwe ngendlela efanele, kuba nzima ukufinyelela iphuzu lokushisela olifunayo.Ingasetshenziselwa izingxenye ezibekwe phezulu noma izingxenye ze-plug-in.

Ngembobo: Ebhodini lesifunda, umugqa weqa usuka kolunye uhlangothi lwebhodi uye kolunye.Imbobo ehlanganisa izintambo ezimbili ibizwa nangokuthi imbobo (ngokuphambene nephedi, akukho ungqimba lwe-solder ohlangothini).Eyaziwa nangokuthi i-metalllization hole, kuphaneli ephindwe kabili kanye ne-PCB ye-multilayer, yokuxhuma intambo ephrintiwe phakathi kwezendlalelo, kungqimba ngalunye kudingeka luxhunywe empambanweni yokubhoboza ucingo emgodini womphakathi, okungukuthi, ngembobo.

Ngobuchwepheshe, ungqimba lwensimbi yi-PCB endaweni eyicylindrical yodonga lwembobo ngokusebenzisa indlela yokubeka amakhemikhali ukuze kuxhunywe ucwecwe lwethusi oludinga ukuxhunywa kungqimba olumaphakathi, kanye nezinhlangothi ezingaphezulu nezingezansi zembobo ukuma kwephedi le-solder eliyindilinga, imingcele yembobo ikakhulukazi ihlanganisa ububanzi obungaphandle bembobo kanye nobukhulu bomgodi.

3. Imiphumela Ehlukene

Ngembobo: imbobo ku-PCB, dlala indima yokuqhuba noma yokukhipha ukushisa.

Iphedi: ipuleti lethusi le-PCB, amanye asebenzisana nembobo yokuxhuma, kanye nepuleti eliyisikwele, elisetshenziswa kakhulu ukunamathisela izingxenye.
