Kunezinhlobo eziningi ze-PCB ngokusebenzisa izimbobo zembobo, futhi izimbobo ezihlukene zingakhethwa ngokuya ngezidingo ezahlukene zohlelo lokusebenza kanye nezidingo zokuklama.Okulandelayo kuzochaza ukuvuleka kwe-PCB embalwa evamile ngezimbobo kanye nomehluko phakathi kwe-PCB ngezimbobo kanye nezimbobo.
一, uhlobo lokuvula lwe-PCB ngembobo
1. Imbobo evamile (PCB Standard Hole) : Ngokuvamile kumklamo we-PCB, imbobo eyindilinga enembobo enkulu noma elingana no-0.4mm ibizwa ngokuthi imbobo evamile.Lesi simbobo sivame ukusetshenziselwa ukuvikela ibhodi le-PCB noxhumo lwephini lengxenye.

2. Imbobo yembobo encane: Imbobo encane isho imbobo eyisiyingi enobubanzi obungaphansi kuka-0.4mm.Ngokukhula kwe-miniaturization yezinto zikagesi, kunesidingo esikhulu sokuklama kwe-PCB, ngakho-ke izimbobo ze-micropore ziya ngokuya zithandwa.Izicelo ze-microaperture zifaka izinto ezincane zikagesi ezifana namalaptop nomakhalekhukhwini.

3. Imbobo Enemicu (Imbobo Enyathelwe) : Izimbobo ezinentambo zifakwa emigodini, ngokuvamile esetshenziselwa ukufaka izingxenye ezinezixhumanisi zokuxhuma ezinentambo, njengezixhumi noma osinki bokushisa.

二, umehluko phakathi kwe-PCB ngembobo kanye nembobo

PCB ngokusebenzisa imbobo futhi ngokusebenzisa imbobo zihlukile ukusetshenziswa PCB ibhodi, kukhona ikakhulukazi umehluko olandelayo:

1. Inhloso Yedizayini Ye-PCB: Izimbobo ze-PCB ziyizimbobo ezibekelwe ngamabomu ekwakhiweni, futhi zizocutshungulwa ukuze kuxhunywe okungenani izendlalelo ezimbili ze-PCB.Ngezimbobo zenzelwe ukuxhuma ungqimba oluthile noma ingxenye, futhi indawo yazo inqunywa ngezidingo zokuklama.

I-2, Uxhumano Lwesiginali (Ukuxhumana Kwesiginali) : I-PCB ngembobo iyiphinikhodi yesignali esuka kungqimba olulodwa iye kwesinye isendlalelo ukuze kuzuzwe ukudluliswa kwesignali.Ngokusebenzisa izimbobo ngokuyinhloko asetshenziselwa ukulungisa amabhodi e-PCB nezingxenye futhi anikeze ukusekela komshini.

3. Inqubo Yokukhiqiza: Izimbobo ze-PCB zizophathwa ngamathuluzi akhethekile nezinto ngesikhathi senqubo yokukhiqiza, ngokuvamile nge-electroplating ukuze kwandiswe ukuqhutshwa kukagesi.Imbobo ngokusebenzisa ilula, ngokuvamile kudingeka kuphela machined imbobo endaweni ehambisana.

4. Ukusekelwa Kwesakhiwo: Ukuba khona kwezimbobo ze-PCB kungakhuphula ukuqina kwesakhiwo nokuqina kwebhodi le-PCB, futhi kudlale indima esekelayo.Nakuba i- through hole ingase futhi yenyuse izinga elithile lokuqina, inhloso yayo enkulu ukuhlinzeka ngemisebenzi engashintshi futhi exhunyiwe.

Kafushane, imbobo ye-PCB ngembobo ihlanganisa imbobo evamile, imbobo encane kanye nembobo enentambo.Umehluko phakathi kwe-PCB ngezimbobo nangezimbobo ubonakala kakhulu enhlosweni yokuklama, uxhumano lwesignali, ubuchwepheshe bokucubungula nokusekelwa kwesakhiwo.Idizayini ehlukene ye-PCB nezidingo zokuhlanganisa zingahlangatshezwana nazo ngokukhetha izinhlobo zokuvula ezihlukene nokusebenzisa izimbobo ezifanele noma izimbobo.
