Ituaiga eseese o laupapa matagaluega

le lolomi laupapa matagaluega or PCB is the physical support board while electrically connecting the various electronic components of the wider system. O lo’o fa’aogaina e le laupapa fa’atonu uaea ta’avale, pa’u ma isi mea e si’uleo mai le ‘apa kopa.

Tasi itu

E pei ona taʻu mai e le igoa, o se PCB itu e tasi e faia i se mea e tasi, e taʻua foi o se “suavai.” I luga o le pito i luga o loʻo i ai se laupepa manifinifi e faia i le ‘apamemea. E galue lenei mea o se taʻavale o faʻailoga eletise.

O ituaiga sili ona taatele o PCBS ma e sili ona lauiloa i le gaosiga o le tele ona o latou tau maualalo. O nei laupapa e masani ona maua i meapueata, calculators ma masini leitio.

E mafai foi ona maua i mamanu faigofie meataalo.

Itu e lua

O laupapa fa’asalalau lolomi fa’alua e galue e pei o laupapa fa’asalalau lolomi e tasi, ae fa’apipi’i i le va o fa’atonuga i itu uma e lua. In addition, they are designed to have holes drilled into the plate.

These holes are placed on the board to allow the circuit to be mounted on either side of the PCB or fed through the board. Additional flexibility and conductive surfaces allow double-sided materials to be used in more advanced applications.

PCBS lua itu e masani ona maua i telefoni feʻaveaʻi, masini faʻatau, siaki taʻavale ma meafaigaluega mita eletise.

Multilayer

O le mamanu e lua itu ma faʻalautele i luga. O le multilayer o se aofa’iga e le itiiti ifo i le tolu (3) PCBS lua itu. They take the technology established here and increase their production capacity.

Size and space are the main advantages of multi-layer PCBS. E mafai ona latou faʻaogaina se laupapa faʻapipiʻi tele nai lo le tele o laupapa.

O latou o se vaega taua o taʻavale televave aua o la latou laupapa e mafai ai ona faʻatulagaina lelei le taʻavale ma le mana.

Faamaaa

Rigid PCBS can be single, double, or multi-layered. Rigidity e fa’atatau i mea e fai ai mea e fai ai laupapa. When a PCB is rigid, it is, as the name implies, made of materials that resist distortion or deformation.

A very common rigid PCB is the motherboard on a computer. Ua mamanuina ina ia tumau ma e mafai ona faʻaaogaina i se tulaga e tasi ma foliga.

Rigid PCBS benefit from ease of maintenance and ease of use. O poloketi uma e iai se nofoaga ma e faʻamaonia manino pe a mamanuina. E le fa’atapula’aina i se mamanu e tasi ma e mafai ona amata mai i le laulau e tasi i le sefulu (10) fa’asologa o le PCB.

vavai

Fetuuna’i PCBS galue i le auala lava e tasi e pei o PCBS malo, ae e faia i mea eseese.

O papatusi malō e faia i mea mautu (o lona uiga e taofi o latou foliga) (e masani lava o se filo tioata), ae o ipu feʻaveaʻi e masani ona faia i palasitika poʻo mea faapena.

O le fetuutuuna’i moni o le aoga autu o PCBS fetuutuunai. E mafai ona fa’asaoina tau ona o lo latou gafatia e “afi” vaega e ono fealua’i ai papa ma’a’a.

The main applications of flexible PCBS are in systems that may cause damage to the environment. O latou mamanu e sili atu ona latou teteʻe i le vevela, vai, pala ma isi elemene e sili atu ona faʻaleagaina papatusi malo.

Faafefiloi ma vaivai

Rigid-flexibility Bridges the gap between the two types built on text and graphics, which is most common in mobile phones and digital cameras.

E aofia ai se seti o ta’amilosaga fetu’una’i e feso’ota’i atu i le tele o papatusi malo. O le mea lea e sili atu ona faigofie le mamanu, aua e tuʻufaʻatasia elemene uma e manaʻomia mo nei vaega i se vaega “tasi”.

E mafai foi ona maua le malosi ma le fetuutuunai i talosaga faafomai.

Alumini tua

O le fa’a’avevelaina o le vevela e totonugalemu i le PCB. Afai o le vevela o le faiga o se iloiloga, o le faʻaaogaina o se PCB pito i tua alumini o le filifiliga sili lea, lea e aofia ai isi faʻamanuiaga manino.

O le fausaga o le PCB e talitutusa lava ma se tulaga tulaga tasi pe faalua, ae o mea e faaaoga e eseese.

E sili atu le umi ma e sili ona faauo i le siosiomaga. O le alumini e le oona ma faigofie tele ona toe fa’aaogaina. On top of that, it’s incredibly cheap, it’s one of the cheapest metals in mining, and it’s cheap to make.

Maualuga taimi

Hf PCBS e le fausia i se auala fou, mo se faʻataʻitaʻiga, faʻatusatusa le tasi i le tele o laulau, ae faʻasino i se ituaiga faʻaoga. E mafai ona fa’aogaina le PCBS maualuga pe a mana’omia le tu’uina atu o fa’ailo i tau e maualuga atu nai lo le 1GHz. They are mainly used in large communication systems.

Fa’amanuiaga ole fa’aogaina ole PCB

E ui o ituaiga taʻitasi o laupapa e iai ona lelei, e tele faʻamanuiaga i le faʻaaogaina o se PCB i le lautele.

Easy trouble shooting and maintenance

O le faʻatulagaina, poʻo le “tala,” o le laupapa e faigofie ai ona iloa mea faʻafitauli ma sui ai

Remove and reattach to board

Le lelei o: E leai se manaʻoga e toe fau le matagaluega atoa pe a faia ni toe faʻaleleia poʻo ni suiga

O le laupapa matagaluega o se fuafuaga ua uma ona fai ma e itiiti se taimi e fau ai nai lo ta’aloga masani

Paʻu maualalo: O se faʻatulagaina lelei o le PCB e mafai ona taʻitaʻia atu i vaega eletise maualalo, e taʻua o le “tautala feʻau.”

Fesoasoani e aveese le pisapisao faaeletonika e mafai ona faaleagaina ai le faatinoga o masini

faatuatuaina: Therefore, the connection of the board is inlaid with copper wire. Leai ni feso’ota’iga matala po’o “uaea lulu.”

O le uelo e faʻafesoʻotaʻi uma vaega i le laupapa lava ia, o lea latou te galulue e tusa lava pe faʻafefe le laupapa.
