Semutengesi wePCB akasiyana PCB, Mavhoriyamu, tungamira nguva sarudzo, isu tine sarudzo yeiyo bandwidth yemhando dzakasiyana dzePCB dzinogona kuvharwa uye dzinogara dziripo mumba.
Zvatinoda kune zvimwe kana zvezvinhu zvakakosha zvinogona zvakare kusangana kazhinji, asi, zvichienderana nezvinodiwa chaizvo, kusvika pamazuva gumi ekushanda vanogona kudikanwa kuti vatore zvinhu.
Ita kuti ubatane nesu uye ukurukure zvaunoda neimwe yeyekutengesa kana cam timu.

Stackup
Iyo 4 layer yakadhindwa Circuit bhodhi iri kuita matatu ezvimwe chete zvigadziko uye pasi pevhu kuita kuti iite kuti iite zvikamu zvizere.
Zvese izvi zviyero zvinoshandiswa pakufamba kwezviratidzo.
Iyo Frst maviri emukati marara akarara mukati meiyo core uye anowanzoitwa sesimba remagetsi kana rinowanzotaurwa nezvemasaini.
Kungotaura chete 4-layer PCB stackup iri kuine 2 yeiyo yeSiki VCC uye pasi pevhu.
ZVINOKOSHA ZVINOKOSHA PCB Kutenga
Zvakawanda zvemagetsi fekitori vatengi vakavhiringidzwa nezve mutengo wePCbs. Kunyangwe vamwe vanhu vane makore mazhinji echiitiko muPCB Kuwanikwa kungasanzwisisa zvizere chikonzero chekutanga. Muchokwadi, iyo PCB mutengo unoumbwa nezvinhu zvinotevera:
Kutanga, mitengo yakasiyana nekuda kwezvakasiyana zvinoshandiswa muPCB.
Kutora zvakajairika zviyero zvakapetwa PCB semuenzaniso, iyo laminate inosiyana kubva kuFr-4, cem-3, etc. ine gobvu kubva ku2.2mm kusvika 3.6mm. Iko ukobvu kwemhangura inosiyana kubva 0.5oz kusvika 6oz, zvese izvo zvakakonzera mutsauko muhombe mutengo. Iyo Soldermask Inki Mitengo zvakare yakasiyana neyakajairwa Thermossa ink zvinhu uye Photo PhotoVy Green Ink zvinhu.
Chechipiri, mitengo yakasiyana nekuda kwekugadzira maitiro ekugadzira.
Maitiro akasiyana ekugadzira anokonzerwa nemari dzakasiyana. Yakadai seBhodhi rakarongedzwa neTIN uye TIN-rakarongwa, chimiro chekupuruzira, kushandisa silika mitsara yemitsara yakaoma ichaita mitezo yakasiyana, zvichikonzera kusiyana kwemutengo.
