PCB iguqulelwe kulwimi lwesiTshayina kuthiwa yibhodi yesekethe eprintiweyo, kuba yenziwa ngokushicilelwa ngombane, okubizwa ngokuba yibhodi yesekethe “eprintiweyo”. I-PCB yinto ebalulekileyo kumzi mveliso we-elektroniki, ngumzimba wenkxaso wezinto ze-elektroniki, ophethe uqhagamshelo lombane lwezinto zombane. I-PCB isetyenziswe ngokubanzi kwimveliso nakwimveliso yeemveliso ze-elektroniki, isizathu sokuba ingasetyenziswa ngokubanzi.

Iimpawu ezizodwa ze-PCB zishwankathelwe ngolu hlobo lulandelayo:

1, ukuxinana kwe-wiring kuphezulu, ubungakanani obuncinci, ubunzima bokukhanya, okulungeleyo ukwenza i-miniaturization yezixhobo ze-elektroniki.

2, kuba iigrafiki zinokuphindeka kunye nokungaguquguquki, ukunciphisa ukungqinisisa kunye neempazamo zebandla, gcina ulondolozo lwezixhobo, ukulungisa ingxaki kunye nexesha lokuhlola.

I-3, ilungele ukusetyenziswa koomatshini, imveliso ezenzekelayo, ukuphucula imveliso kunye nokunciphisa iindleko zezixhobo ze-elektroniki.

I-4, uyilo lunokumiselwa ngokusemgangathweni, lubenako ukutshintshiselana.

Ibhodi yesekethe eprintiweyo (i-PCBA) yiBhodi yeeSekethi eziprintiweyo (i-PCB), iBhodi yeSekethe eprintiweyo (i-SMT), kunye ne-DIP plug-in (DIP). Qaphela: I-SMT kunye ne-DIP zombini ziindlela zokudibanisa iinxalenye kwi-PCB. Umahluko ophambili kukuba i-SMT ayifuni mingxunya yokomba kwi-PCB. Kwi-DIP, i-PIN ye-PIN yenxalenye ifakwe kumngxunya osele ugqityiwe.

Itekhnoloji yokuphakama komphezulu we-SMT isebenzisa umatshini we-SMT ukukhwela ezinye iindawo ezincinci kwibhodi ye-PCB. Inkqubo yayo yemveliso ibandakanya ukubekwa kwebhodi ye-PCB, ukuprinta ukunamathisela i-solder, ukunyusa umatshini we-SMT, isithando somlilo esingasemva kunye nohlolo lwemveliso. I-DIP, okanye “iplagi-in,” kukufakwa kwenxalenye kwibhodi ye-PCB, eyindibaniselwano yenxalenye ekwimo ye-plug-in xa icandelo likhulu kwaye lingalungelanga iteknoloji yentaba. Eyona nkqubo yayo iphambili yokuvelisa yile: cola i-gum, iplagi-ngaphakathi, ukuhlolwa, ukujija okuguqulweyo, uguqulelo lwebrashi kunye nokwenza uhlolo.

Njengoko kunokubonwa kwintshayelelo engentla, iPCBA ngokubanzi ibhekisa kwinkqubo yokulungisa, enokuqondwa njengebhodi yesekethe egqityiweyo. I-PCBA inokubalwa kuphela emva kokuba zonke iinkqubo zebhodi ye-PCB zigqityiwe. I-PCB yibhodi yesekethe eprintiweyo engenanto engenanxalenye kuyo. Ngokubanzi, i-PCBA yibhodi egqityiweyo; I-PCB ibhodi engenanto.
