Tagata fou e masani ona fenumiai “PCB schematic” with “PCB design document” when talking about printed circuit boards, but they actually mean different things. Malamalama i le eseesega i le va oi latou o le ki i le manuia PCB gaosiga, o lea o lenei tusitusiga o le a talepeina ai le eseesega autu i le va o PCB polokalame ma PCB mamanu mo tagata amata e faia lenei sili lelei.

Ae e te leʻi oʻo i eseesega i le va o polokalame faʻataʻitaʻi ma le ata, e taua le iloa, o le a le 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. E le ola le eletise e aunoa ma le PCBS.

Ata faʻapitoa ole PCB ma le ata ole PCB

O le polokalame PCB ose ata faigofie e lua-itu e faʻaalia ai le aoga ma fesoʻotaʻiga i le va o vaega eseese. PCB design o faʻatulagaina tolu-itu, ina ia mautinoa le faʻagaioiga masani o le taʻamilosaga pe a maeʻa le makaina o le nofoaga o vaega.

Therefore, PCB schematic is the first part of the design of printed circuit board. Lenei o se ata faʻailoga, pe tusia pe faʻamaumauga, e faʻaaogaina faʻailoga malilie e faʻamatala ai fesoʻotaʻiga fesoʻotaʻiga. E faʻailoaina foʻi vaega e faʻaaoga ma faʻafefea ona faʻaaogaina.

E pei ona taʻu mai e le igoa, o le PCB schematic o se fuafuaga, o se mamanu. E le faʻamaʻoti maia le mea o le a tuʻu ai vaega. Nai lo lea, o le polokalame faʻatulagaina Faʻafefea e le PCB le a iu ina ausia fesoʻotaʻiga ma avea ma vaega taua o le fuafuaga faʻagasologa.

A maeʻa loa le ata, ona sosoʻo mai loa lea o le PCB. Design is the layout or physical representation of the PCB schematic, including copper wiring and hole layout. O le PCB design faʻaalia le nofoaga o vaega ma la latou fesoʻotaʻiga i le ‘apamemea.

PCB design is a performance-related phase. Na fausia e Inisinia ni vaega moni i luga o ata a le PCB, faʻatagaina latou e faʻataʻitaʻia pe o lelei mea faigaluega. E pei ona taʻua muamua, soʻo se tasi e tatau ona mafai ona malamalama i le polokalame PCB, ae e le faigofie ona malamalama i lona aoga e ala i le vaʻai i le faʻataʻitaʻiga.

O vaega uma e lua ua maeʻa, ma a maeʻa ona e faʻamalieina i le PCB’s performance, oe manaʻomia le faʻatinoina e ala i le gaosi oloa.

Elemeni polokalame ole PCB

O lenei ua tatou malamalama i le eseesega i le va o le lua, sei o tatou vaʻavaʻai vaʻavaʻai i elemene o le PCB ata. E pei ona matou taʻua, o fesoʻotaʻiga uma e vaʻaia, ae e iai nai lapataiga e te mafaufau i ai:

In order to see the connections clearly, they are not created to scale; I le PCB design, e mafai ona latalata tele le tasi i le isi

Nisi fesoʻotaʻiga ono kolosi tasi, lea e toetoe lava a le mafai

O nisi fesoʻotaʻiga ono i itu faʻafeagai o le faʻatulagaga, ma faʻailoga e faʻailoa mai ai o loʻo latou fesoʻotaʻi

Lenei PCB “blueprint” mafai ona avea ma se itulau, lua itulau, poʻo ni nai itulau faʻamatalaina mea uma e manaʻomia e aofia ai i le mamanu

Tasi le mea taua e maitauina o le sili atu faigata faʻataʻitaʻi mafai ona faʻavasegaina e gaioiga e faʻaleleia atili faitau. O le faʻatulagaina o fesoʻotaʻiga i lenei auala e le tupu i le isi laʻasaga, ma o le polokalame e masani ona le fetaui ma le ata mulimuli o le ata 3D.

PCB Elemene Fuafua

Ua oʻo nei i le taimi e vaʻavaʻai totoʻa ai i elemeni o le pepa faʻamaonia PCB. I lenei laasaga tatou te o ese mai tusi tusitusia tusitusi i faʻaletino tino foliga fausia fausia faʻaaogaina laminate po o keramika mea. PCBS fetuutuunai o loʻo faʻaaogaina mo sili atu ona faigata talosaga pe a manaʻomia se faʻaopoopoina avanoa avanoa.

O mea o loʻo i totonu ole pepa faʻamaumauga ole PCB, e mulimuli mai ile faʻailoga na tuʻuina i lalo e le polokalame, ae pei ona taʻua muamua, e matua ‘eseʻese lava foliga o mea ia e lua. Ua uma ona tatou talanoaina polokalame PCB, ae o a eseesega e mafai ona maitauina i le pepa tusia?

A matou talanoa e uiga i le PCB design document, o loʻo matou talanoa e uiga i se 3D faʻataʻitaʻiga e aofia ai le lolomi laupapa matagaluega ma le mamanu pepa. Latou mafai ona nofofua pe tele-faʻapipiʻi, e ui lava e lua ni vaega e sili ona taatele. E mafai ona matou matauina ni eseʻesega i le va o polokalame ole PCB male PCB design documents:

O vaega uma e saʻo le tele ma faʻatulagaina

Afai e le tatau ona faʻafesoʻotaʻi ni manatu se lua, e tatau ona faʻataʻamilomilo pe fesuiaʻi i seisi vaega ole PCB e aloese ai mai le sopoʻia o le tasi ma le isi vaega.

I se faʻaopopoga, e pei ona matou talanoaina puʻupuʻu, o le PCB design e sili atu ona popole i le faʻatinoina moni o galuega, aua o lenei e mo sina vaega o le faʻamaoniga vaega o le oloa mulimuli. I le taimi lea, o le aoga o le moni galuega o le mamanu tatau ona amata i taʻaloga, ma o le tino manaʻoga o le lolomi laupapa matagaluega e tatau ona iloiloina. O nisi o nei e aofia ai:

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

E i ai fesoʻotaʻiga faataamilo i itu

I le tulaga o le taimi nei ma le vevela, o le a le mafiafia e tatau ona tele ituaiga faʻailoga

Talu ai o tapulaʻa faʻaletino ma manaʻoga o lona uiga o pepa faʻamaumauga a le PCB e masani ona matua eseʻese mai le mamanu i luga o le polokalame, o ata o loʻo aofia ai silkscreen lolomiga. O le laupepa lolomiina vaega faʻaalia ai mataʻitusi, numera ma faʻailoga e fesoasoani inisinia faʻaputuputuina ma faʻaaoga le laupapa.

E manaʻomia le galue o mea uma pei ona fuafuaina pe a maeʻa ona potopoto i luga o le lolomi laupapa matagaluega. A leai, e tatau ona toe tusia.

faaiuga

E ui lava e le masani ona le mautonu PCB polokalame faʻamaumau ma pepa faʻamaonia PCB, o le mea moni o le faia o faʻamaumauga PCB ma le PCB tisaini faʻasino i lua tuʻutuʻuga faiga pe a fausiaina se lolomi laupapa. PCB design, o se vaega taua o PCB faʻatinoina ma le faʻamaoni, tatau ona faia ae le i faia le faia o se PCB ata faʻataʻitaʻiga e mafai ona tusia ai le gaioiga tafe.
