Uthini umahluko phakathi kwebhodi yesekethe kunye nebhodi yesekethe?Ebomini, abantu abaninzi babhidanisa iibhodi zeesekethe kunye neebhodi zeesekethe.Enyanisweni, umahluko phakathi kwezi zibini umkhulu ngokwentelekiso.Ngokuqhelekileyo, iibhodi zeesekethe zibhekisela kwii-PCB ezingenanto, oko kukuthi, iibhodi eziprintiweyo ezingenawo nawaphi na amacandelo axhonywe kuzo.Ibhodi yesekethe ibhekiselele kwibhodi eprintiweyo efakwe ngamacandelo e-elektroniki kwaye inokuqonda imisebenzi eqhelekileyo.Basenokuqondwa njengomahluko phakathi kwe-substrate kunye nebhodi egqityiweyo!
Ibhodi yesekethe idla ngokubizwa ngokuba yiPCB, kwaye igama layo elipheleleyo ngesiNgesi lithi:Ibhodi yeSekethe eprintiweyo.Ngokweempawu, inokwahlulwa ibe ziindidi ezintathu: ibhodi yomgca omnye, ibhodi ephindwe kabini kunye nebhodi ye-multi-layer.Ibhodi yebhodi enye ibhekisela kwibhodi yesiphaluka kunye neengcingo ezigxininiswe kwelinye icala, kwaye ibhodi yecala eliphindwe kabini libhekisela kwibhodi yesiphaluka ngeengcingo ezisasazwa kumacala omabini.I-multi-layer single ibhekisela kwibhodi yesekethe enamacala angaphezu kwamabini;
Iibhodi zesekethe zinokwahlulwa zibe ziindidi ezintathu eziphambili ngokweempawu zazo: iibhodi eziguquguqukayo, iibhodi eziqinileyo, kunye neebhodi ezithambileyo.Phakathi kwazo, iibhodi eziguquguqukayo zibizwa ngokuba yi-FPCs, eyenziwa ngokukodwa ngezinto eziguquguqukayo ze-substrate ezifana neefilimu ze-polyester.Ineempawu zokuxinana kwendibano ephezulu, ilula kwaye incinci, kwaye inokugoba.Iibhodi eziqinileyo zibizwa ngokuba ziiPCBs.Zenziwe ngezinto eziqinileyo ze-substrate ezifana ne-copper-clad laminates.Okwangoku zezona zisetyenziswa kakhulu.Iibhodi ze-Rigid-flex zikwabizwa ngokuba yi-FPCBs.Yenziwe ngebhodi ethambileyo kunye nebhodi enzima ngokusebenzisa i-lamination kunye nezinye iinkqubo, kwaye ineempawu zombini PCB kunye ne-FPC.
Ibhodi yesekethe idla ngokubhekisa kwibhodi yesekethe ene-SMT patch mounting okanye i-DIP plug-in plug-in plug-in components, enokuqonda imisebenzi eqhelekileyo yemveliso.Ikwabizwa ngokuba yiPCBA, kwaye igama elipheleleyo lesiNgesi yiNdibano yeBhodi yeSekethe eprintiweyo.Zimbini iindlela zokuvelisa ngokubanzi, enye yinkqubo yokuhlanganisa itshiphu ye-SMT, enye yinkqubo yokuhlanganisa iplagi ye-DIP, kwaye iindlela ezimbini zokuvelisa nazo zingasetyenziswa xa kudityaniswa.Ewe, oku ngasentla ngumxholo wonke womahluko phakathi kwebhodi yesekethe kunye nebhodi yesekethe.
