PCB inoshandurwa muchiChinese inonzi yakadhindwa wedunhu bhodhi, nekuti inogadzirwa nemagetsi kudhinda, inonzi “yakadhindwa” redunhu bhodhi. Pcb chinhu chakakosha chemagetsi mune yemagetsi indasitiri, ndiyo inotsigira muviri wemagetsi zvigadzirwa, ndiye mutakuri wemagetsi kubatana kwemagetsi emagetsi. Pcb rave nevakawanda kushandiswa kugadzirwa uye mukugadzira zvemagetsi zvigadzirwa, chikonzero nei inogona nevakawanda kushandiswa.

Izvo zvakasarudzika hunhu hwePCB zvakapfupikiswa seinotevera:

1, wiring density yakakwira, diki saizi, kurema kurema, inokodzera kune miniaturization yemagetsi zvigadzirwa.

2, nekuti iyo mifananidzo ine kudzokorora uye kusachinjika, inoderedza wiring uye gungano zvikanganiso, chengetedza michina yekugadzirisa, kugadzirisa dambudziko uye kuongorora nguva.

3, inobatsira kugadzira, otomatiki kugadzirwa, kunatsiridza kugadzirwa kwevashandi uye kudzikisa mutengo wemidziyo yemagetsi.

4, dhizaini inogona kuve yakamisikidzwa, inobatsira kuchinjanisa.

Iyo Yakadhindwa Dunhu Bhodhi (PCBA) iri Rakadhindwa Dunhu Bhodhi (PCB), Rakadhindwa Dunhu Bhodhi (SMT), uye DIP plug-in (DIP). Ongorora: SMT uye DIP dzose dziri mbiri nzira dzekubatanidza zvikamu paPCB. Musiyano mukuru ndewekuti SMT haidi kuchera maburi muPCB. MuDIP, PIN yePIN yechikamu ichi inoiswa mugomba rakatochekwa.

SMT pamusoro pegomo tekinoroji inonyanya kushandisa SMT muchina kukwidza zvimwe zvidiki zvidimbu pane pcb board. Maitiro aro ekugadzira anosanganisira pcb pabhodhi yekumisikidza, kudhinda solder paste, SMT muchina unosimudza, kumashure kwesimbi yekutsvaira uye kuongorora kwekugadzira. DIP, kana “plug-in,” ndiko kuiswa kwechikamu pabhodhi rePCB, kunova kubatanidzwa kwechikamu muchimiro che plug-in apo chikamu chacho chakakura uye chisina kukodzera tekinoroji yegomo. Yayo huru yekugadzira maitiro ndeye: namatidza chingamu, plug-in, kuongorora, wave soldering, brashi vhezheni uye yakaita kuongorora.

Sezvinoonekwa kubva pachirevo chiri pamusoro, PCBA inowanzoreva maitiro ekugadzirisa, ayo anogona kunzwisiswa sebhodhi redunhu rapera. PCBA inogona kuverengerwa chete mushure mekunge maitirwo ese pabhodhi rePCB apera. Pcb iri isina chinhu rakadhindwa redunhu bhodhi isina zvikamu pairi. Kazhinji, PCBA ndiro rakapedzwa bhodhi; Pcb yakashama bhodhi.
