Semupi weakasiyana siyana ePCB tekinoroji, mavhoriyamu, sarudzo dzekutungamira nguva, isu tine sarudzo yezvinhu zvakajairika izvo bandwidth hombe yemhando dzakasiyana dzePCB inogona kuvharwa uye inogara iripo mumba.
Zvinodiwa zvezvimwe kana zvezvishandiso zvakakosha zvinogonawo kusangana muzviitiko zvakawanda, asi, zvichienderana nezvinodiwa chaizvo, anosvika mazuva gumi ekushanda anogona kudiwa kuti utore zvinhu.
Bata nesu uye kurukura zvaunoda neimwe yekutengesa kwedu kana CAM timu.
Zvigadzirwa zvakajairika zviri mustock:

Stackup
Iyo 4 layer yakadhindwa yedunhu bhodhi stackup ine 3 yeimwe chete akaturikidzana uye yepasi layer ichiita iyo 4 akaturikidzana.
Ese aya mataira anoshandiswa pakufambisa kwemasaini.
Mawashi maviri ekutanga emukati akarara mukati mepakati uye anowanzo shandiswa semagetsi emagetsi kana anowanzo kunzi nzira yemasaini.
Kungotaura chete 4-layer PCB stackup ine 2 ye singlea VCC uye yepasi layer.
Mapoinzi akakosha ekutenga pcb
Vazhinji vanotenga zvemagetsi fekitori vakavhiringidzika nezve mutengo wePCB.kunyangwe vamwe vanhu vane makore mazhinji eruzivo mukutenga kwePCB vangasanzwisisa zvizere chikonzero chepakutanga.Muchokwadi, mutengo wePCB unoumbwa nezvinhu zvinotevera:
Chekutanga, mitengo yacho yakasiyana nekuda kwezvinhu zvakasiyana zvinoshandiswa muPCB.
Kutora zvakajairwa kaviri akaturikidzana pcb semuenzaniso, iyo laminate inosiyana kubva kuFR-4, CEM-3, nezvimwewo nehupamhi hwepakati kubva 0.2mm kusvika 3.6mm.Ukobvu hwemhangura hunosiyana kubva pa0.5Oz kusvika 6Oz, zvese zvakakonzera musiyano mukuru wemutengo.Iyo soldermask ingi mitengo yakasiyanawo neyakajairika thermosetting inki zvinhu uye photosensitive girinhi ingi zvinhu.
Chechipiri, mitengo yacho yakasiyana nekuda kwemaitiro akasiyana ekugadzira.
Maitiro ekugadzira akasiyana anoguma nemitengo yakasiyana.Zvakadai sebhodhi-yakavezwa bhodhi uye tin-plated bhodhi, chimiro chenzira uye punching, kushandiswa kwemitsetse yesilika yekrini uye mitsara yakaoma yefirimu ichaumba mari yakasiyana, zvichiita kuti mutengo usiyane.
