Yintoni umahluko phakathi kwebhodi yesekethe kunye nebhodi PCB

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.
