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 ezinemisebe yokuxhumana enentambo, 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 kanye 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.
