VaNewbies vanowanzovhiringidza “PCB schematic” with “PCB design document” when talking about printed circuit boards, but they actually mean different things. Kunzwisisa mutsauko uripo pakati pavo ndiyo kiyi yekubudirira kwePBB kugadzira, saka chinyorwa ichi chinokanganisa misiyano yakakosha pakati pePCB schematics nePCB dhizaini yevatangi kuti vaite izvi zvirinani.

Usati wapinda mukusiyana pakati pechirongwa uye dhizaini, zvakakosha kuti uzive, chii chinonzi PCB? Inside electronic equipment, there are printed circuit boards, also known as printed circuit boards. The green circuit board, made of precious metal, connects all the electrical components of the device and enables it to function properly. Zvemagetsi hazvishande pasina PCBS.

Pcb schematic dhayagiramu uye pcb dhizaini

Iyo PCB schematic iri nyore maviri-mativi wedunhu dhizaini inoratidza iko kushanda uye kubatana pakati pezvinhu zvakasiyana. Pcb dhizaini ndeye-mativi marongero, kuitira kuti uve nechokwadi cheakajairika mashandiro wedunhu mushure mekumaka nzvimbo yezvinhu.

Therefore, PCB schematic is the first part of the design of printed circuit board. Ichi chiratidziro chemifananidzo, chingave chakanyorwa kana dhata, icho chinoshandisa zviratidzo zvakabvumirana kutsanangura kubatana kwedunhu. Iyo zvakare inoratidza kune izvo zvinoshandiswa kuti zvishandiswe uye nemabatiro avakaita wired.

Sezvinoreva zita iri, chirongwa chePCB chirongwa, chirongwa. Izvo hazvitsanangure kuti izvo zvikamu zvichaiswa kupi. Panzvimbo iyoyo, iyo schematic Inoratidzira kuti iyo PCB inozopedzisira yawana sei kubatana uye inoita chikamu chakakosha chegadziriro yekuronga.

Kana mapurani acho angopera, iyo PCB dhizaini inouya inotevera. Design is the layout or physical representation of the PCB schematic, including copper wiring and hole layout. Dhizaini yePBB inoratidza nzvimbo yezvinhu uye kubatana kwavo nemhangura.

PCB design is a performance-related phase. Mainjiniya akavaka chaiwo zvinhu pamusoro pePCB dhizaini, achivabvumidza kuyedza kana iyo michina yakashanda nemazvo. Sezvambotaurwa, chero munhu anofanirwa kunzwisisa iyo PCB schematic, asi hazvisi nyore kunzwisisa mashandiro ayo nekutarisa prototype.

Mativi ese ari maviri akakwana, uye kana uchinge wagutsikana nekuita kwePBB, unofanirwa kuzviita kuburikidza nemugadziri.

Pcb zvirongwa

Iye zvino zvatiri kunzwisisa mutsauko uripo pakati pezviviri, ngatitarisei zvakanyanya zvinhu zvePCB schematic. Sezvatakataura, zvese zvinongedzo zvinoonekwa, asi pane mashoma mapako ekuchengeta mundangariro:

In order to see the connections clearly, they are not created to scale; Mukugadzirwa kwePCB, vanogona kuve padhuze nepadhuze

Kumwe kubatana kunogona kuyambuka, izvo zvisingaite

Kumwe kubatana kunogona kuve kuri pamativi akatarisana ehurongwa, aine mamaki anoratidza kuti akabatana

Iyi PCB “purani” inogona kunge iri peji, maviri mapeji, kana kunyangwe akati wandei mapeji anotsanangura zvese zvinoda kuverengerwa mukugadzirwa.

Imwe yekupedzisira poindi yekucherechedza ndeyekuti mamwe akaomarara maschematics anogona kuiswa mumapoka nebasa rekuvandudza kuverenga. Kuronga kubatana nenzira iyi hakuitike padanho rinotevera, uye iyo schematic kazhinji haifanane neyekupedzisira dhizaini yeiyo 3D modhi.

Pcb Dhizaini Zvinhu

Ino yave nguva yekutarisisa zvinhu zvePCB dhizaini dhizaini. Padanho rino tinobva pamabhururu akanyorwa tichienda kumumiriri hwakavakwa uchishandisa laminate kana zvigadzirwa zvedongo. Flexible PCBS inoshandiswa kune mamwe maitiro akaomarara panodiwa nzvimbo yekuwedzera compact.

Izvo zvirimo zvePCB dhizaini gwaro rinotevera gwaro rakaiswa pasi nesystem maitiro, asi, sezvambotaurwa, maviri anotaridzika akasiyana zvakanyanya. Takatokurukura nezvePCB schematics, asi misiyano ipi inogona kucherechedzwa mugwaro rekugadzira?

Kana isu tichitaura nezve pcb dhizaini dhizaini, tiri kutaura nezve 3D modhi inosanganisira yakadhindwa redunhu bhodhi uye dhizaini dhizaini. Vanogona kuve vasina kuroorwa kana akawanda-akaturikidzana, kunyangwe zvidimbu zviviri zviri zvakajairika. Tinogona kucherechedza mimwe misiyano pakati pePCB schematics uye pcb magwaro ekugadzira:

Zvese zvinhu zvakaenzana saizi uye zvakamisikidzwa

Kana mapoinzi maviri asingafanirwe kuve nehukama, anofanirwa kutenderedzwa kana kuchinjirwa kune imwe pcb dara kuti arege kuyambuka pane imwecheteyo

Uye zvakare, sezvatakakurukura muchidimbu, pcb dhizaini inonyanya kunetsekana nekuita chaiko, sezvo ichi chiri chikamu chekusimbisa chikamu chechigadzirwa chekupedzisira. Panguva ino, kushanda kwebasa chairo dhizaini kunofanirwa kuitika, uye zvinodiwa panyama zvebhodhi redunhu rakadhindwa rinofanirwa kutariswa. Mamwe acho anosanganisira:

How is the spacing of the components allowed for adequate heat distribution

Kune zvinongedzo zvakatenderedza micheto

Panyaya yezvazvino uye kupisa, kukura kwakafanira sei kwakasiyana matanho

Nekuti kukwana kwemuviri uye zvinodiwa zvinoreva kuti pcb magadzirirwo magwaro anowanzo tarisa akasiyana zvakanyanya kubva dhizaini pane yechirongwa, magadzirirwo magwaro anosanganisira silkscreen kudhinda matete. Iyo yekudhinda yekuratidzira dura inoratidza mavara, manhamba uye zviratidzo kubatsira mainjiniya kuungana uye kushandisa bhodhi.

Zvinotarisirwa kuti zvese zvinhu zvinoshanda sezvakarongwa mushure mekuunganidzwa pabhodhi redunhu rakadhindwa. Kana zvisiri, inoda kutorwazve.

kugumisa

Kunyangwe pcb schematics uye pcb magadzirirwo magwaro achiwanzo kuvhiringidzika, kunyatso kuita PCB schematics uye pcb dhizaini inongedzera kune maviri akapatsanuka maitiro kana uchigadzira yakadhindwa bhodhi. Pcb dhizaini, inova chikamu chakakosha chePCB kuita uye kuvimbika, inofanirwa kuitwa pasati pasikwa pcb yemuchato dhizaini iyo inogona kukwevera maitiro kuyerera.
