Nguwuphi umahluko phakathi kwe-PCB kunye nePCBA?

I-PCB: Ibhodi yesekethe eprintiweyo yiBhodi engenazixhobo ze-elektroniki. Ibunjwe ikakhulu yisekethe ye-foil, yobhedu yobhedu kunye nepali. Isekethe yenziwa kwicandelo le-etch kunye nezinye iinkqubo, njengenqanaba elingenanto, kuphela isakhelo esisiseko kunye nendawo yokunxibelelana kunye neendlela ezilandelayo ze-elektroniki kuphela.

I-incrared PCBA: Indibano yebhodi yebhodi yesekethe iprintiweyo emva kokufaka izinto ezahlukeneyo ze-elektroniki (ezinjenge-chips, kunye nee-chip, kwaye emva kothotho lweenkqubo ezifana ne-welding kunye nokulungisa ingxaki. Ilingana nokucwangcisa abadlali (izinto ze-elektroniki) kwinqanaba, kwaye ziphinde ziziqhelanise (ukulungisa ingxaki), kwaye zinokuhleza ngokuthe ngqo "ukwenza" ukusebenza kweemveliso ze-elektroniki).

2, Ukwahluka kwenkqubo yokwenziwa kweMveliso

I-PCB : Owokuqala uyilo, apho iinjineli zisebenzisa isoftware ekhethekileyo ukucwangcisa umkhombandlela kunye nokubekwa kwamacandelo. Ke yinkqubo yemveliso, kubandakanya ukuveliswa kwesekethe yangaphakathi, njengokusetyenziswa kwe-Lithography, itekhnoloji ye-etching ukwenza isekethe yangaphakathi kwiplate yobhedu; Emva koko laMalisa (leBhodi ye-Winde-Wile), i-Inter yangaphakathi kunye ne-inshurensi ye-inshurensi; Emva koko, ukuveliswa kwesekethe yangaphandle kunye nonyango olungaphandle, njengokubekwa kwe-tin, igolide yokuphucula ukusebenza kwepad.

I-PCBA: Ukuthengwa kwezinto zokuqala, khetha iindawo ezihlangabezana neemfuno. Emva koko itekhnoloji yentaba ye-SMT (i-SMT) okanye i-plug-in (dip) isetyenziselwa ukunyusa izinto kwi-PCB. I-SMT kukonyusa izinto ezincinci ngokubhaliweyo ngokuzenzekelayo kwizixhobo ezenzekelayo, kwaye idiphu isetyenziselwa ukufakelwa kwePIN zamacandelo amakhulu. Emva koko, ukuthengisa kwenziwa, izinto ze-SMT zivulwa ezithengisiweyo, kwaye izinto ze-DIP zaza zaza zathengiswa ngesandla okanye ngesandla. Okokugqibela, kuhlolwa kwenziwa, kubandakanya uvavanyo lokujonga kunye novavanyo lwendlela yokusebenza kombane.

3, imeko yesicelo:

I-PCB: Kwinqanaba lokuqala uyilo lwemveliso ngombane, isetyenziselwa ukuqinisekisa ukuba kunokwenzeka kuyilo lwesekethe kwaye ubone ukuba ngaba umbeko sesekethe usengqiqweni. Kwangelo xesha, kwimisebenzi ethile yemveliso elula yemveliso ye-elektroniki okanye iimeko zemfundo, njengeBhodi yeSekethe yabasebenzisi ukuba zifake izinto kunye namava inkqubo yemveliso ye-elektroniki.

I-PCBA: isetyenziswa ngokubanzi kwiimveliso ezahlukeneyo ze-elektroniki, ezinje ngeefowuni ezi-smart, izixhobo zetafile, izixhobo zokulawula imizi-mveliso, njl. Njl. Njl. licandelo eliphambili leemveliso ze-elektroniki lokufezekisa umsebenzi.
