Ndeupi musiyano pakati pebhodhi redunhu nebhodhi redunhu?Muhupenyu, vanhu vazhinji vanovhiringidza mapuranga ematunhu nemapuranga ematunhu.Kutaura zvazviri, musiyano pakati pezviviri izvi wakakura.Kazhinji, mabhodhi edunhu anoreva maPCB asina chinhu, kureva, mabhodhi akadhindwa asina chero zvikamu zvakaiswa paari.Bhodhi redunhu rinoreva bhodhi rakadhindwa iro rakaiswa nezvinhu zvemagetsi uye rinogona kuona mabasa akajairika.Vanogonawo kunzwisiswa semusiyano pakati pe substrate uye bhodhi rakapedzwa!
Bhodhi redunhu rinowanzodaidzwa kunzi PCB, uye zita raro rakazara muChirungu nderekuti:Yakadhindwa Circuit Board.Zvinoenderana nehunhu, inogona kukamurwa kuita marudzi matatu: single-layer board, double-layer board uye multi-layer board.Bhodhi-yepamusoro-soro inoreva bhodhi redunhu rine waya dzakanangidzirwa kune rumwe rutivi, uye bhodhi remativi maviri rinoreva bhodhi redunhu rine waya dzakagoverwa kumativi ose.Iyo yakawanda-layer single inoreva bhodhi redunhu rine mativi anopfuura maviri;
Mabhodhi edunhu anogona kupatsanurwa muzvikamu zvitatu zvikuru zvichienderana nehunhu hwawo: mapuranga anochinjika, mabhodhi akaomarara, uye mabhodhi akapfava.Pakati pawo, mabhodhi anochinjika anonzi maFPC, ayo anonyanya kugadzirwa nezvinhu zvinochinjika substrate senge polyester mafirimu.Iyo ine hunhu hwekusangana kwakakwira, kujeka uye kutetepa, uye inogona kubhenda.Mabhodhi akaomarara anowanzo kunzi PCBs.Iwo akagadzirwa neakaomesesa substrate zvinhu senge copper-clad laminates.Parizvino ndiwo anonyanya kushandiswa.Rigid-flex boards anonziwo FPCBs.Yakagadzirwa nebhodhi yakapfava uye yakaoma bhodhi kuburikidza nelamination uye mamwe maitiro, uye ine hunhu hwezvose zviri zviviri PCB neFPC.
Iro redunhu rinowanzo reva bhodhi redunhu rine SMT chigamba mounting kana DIP plug-in plug-in zvemagetsi zvikamu, izvo zvinogona kuona zvakajairika chigadzirwa mabasa.Inonzi zvakare PCBA, uye zita rakazara rechirungu rinonzi Printed Circuit Board Assembly.Panowanzova nzira mbiri dzekugadzira, imwe ndeye SMT chip assembly process, imwe yacho DIP plug-in assembly process, uye nzira mbiri dzekugadzira dzinogona kushandiswa dzakasanganiswa.Zvakanaka, zviri pamusoro apa ndizvo zvese zvemusiyano pakati pebhodhi redunhu nebhodhi redunhu.
