Lolomi laupapa matagaluega (PCBS) o laupepa faia i fau tioata, vavae epoxy resins poʻo isi mea laminated. E mafai ona maua le PCBS ile tele o eletise ma eletise vaega (faʻataʻitaʻiga, faʻatagi leo, leitio, radars, komepiuta, ma isi). Eseese ituaiga o PCBS e mafai ona faʻalagolago i le tusi talosaga. What are the various types of PCBS? Faitau e saili.

What are the different types of PCBS?

PCBS are usually classified by frequency, number of layers used, and substrate. O nisi ituaiga lauiloa o loʻo talanoaina i lalo.

L tasi itu itu PCB

Single-sided PCB is the basic type of circuit board, consisting of only one layer of substrate or base material. The layer is covered with a thin metal, copper, which is a good conductor of electricity. O nei PCBS o loʻo iai foʻi le puipuia solder resist layer lea e faʻaoga i le pito i luga ole vaega apamemea faʻatasi ma le silkscreen coating. Nisi o mea lelei e ofoina tasi-itu PCBS ofo atu:

Single-sided PCB is used for mass production and low cost.

O nei PCBS o loʻo faʻaaogaina i ni taʻamilosaga faigofie e pei o masini eletise, moligafua, masini faʻafiafia ma meataʻalo eletise.

L double-sided PCB

Uma itu o le lua-itu PCB maua uʻamea conductive faaputuga. Lua i le matagaluega laupapa faʻatagaina vaega uʻamea e fesoʻotaʻi mai le tasi itu i le isi. These PCBS are connected to the circuit on either side by either through-hole or surface-mount techniques. O le auala-lua auala e aofia ai le pasiina o le taʻitaʻiga potopotoga e ala i se muaʻi viliina pu i le laupapa ma ona faʻamau i le pad i le isi itu. O le faʻapipiʻiina i luga e aofia ai le tuʻu saʻo o vaega eletise i luga o le laupapa matagaluega. PCBS lua-itu ofo mai mea lelei nei:

Luga faʻapipiʻi faʻatagaina sili atu matagaluega e fesoʻotaʻi i le laupapa nai lo le faʻaputuina pu.

O nei PCBS e lautele faʻaaogaina i telefoni feaveaʻi polokalama, eletise mataituina, mea e fai ai suʻega, mea e faʻatele ai ma isi tele polokalama.

L multilayer PCB

A multilayer PCB o se lolomi laupapa matagaluega aofia ai sili atu ma le lua apamemea faaputuga, e pei o 4L, 6L, 8L, ma isi O nei PCBS faʻalauteleina le tekonolosi faʻaaogaina i lua-itu PCBS. O le faaputuga o le substrate ma faʻaʻesega vavaeeseina le faaputuga i le tele-vaega PCB. PCBS are compact in size and offer weight and space advantages. Nisi o mea lelei e ofoina mai e multilayer PCBS o:

Eseese-vaega PCBS maua ai se tikeri maualuga o le fetuʻutuʻunaʻi mamanu.

Nei PCBS faia se taua vaega i maualuga-saosaoa taʻamilosaga. Latou saunia sili atu avanoa mo conductor faʻataʻitaʻiga ma mana eletise.

L maumaa PCB

Hard PCBS o mea na e faia i mea mautu ma e le mafai ona piʻo. Nisi o taua taua latou te ofaina:

O nei PCBS e maopoopo, faʻamautinoaina o le tele o faʻalavelave laʻitiiti e faia i latou.

Hard PCBS are easy to repair and maintain because all components are clearly marked. E le gata i lea, o auala faʻailo ua lelei faʻatulagaina.

L PCB fetuutuunai

PCB fetuutuunai o loʻo fausia i luga o mea e faigofie ona faʻavae. These PCBS are available in single-sided, double-sided and multi-layer formats. Lenei fesoasoani faʻaititia lavelave i totonu o vaega masini. Some of the advantages these PCBS offer are:

Nei PCBS fesoasoani faʻasaoina le tele o avanoa ma faʻaititia le aofaʻiga mamafa o le laupapa.

Flexible PCBS help reduce board size and are therefore ideal for a variety of applications requiring high signal routing density.

O nei PCBS ua fuafuaina mo faʻagaioiga tulaga lea e iloiloina ai le vevela ma le maualuga.

L Maʻaʻa – fetuutuunai -PCB

Rigid flexible – A PCB is a combination of rigid and flexible circuit boards. They consist of multiple layers of flexible circuits connected to more than one rigid plate.

These PCBS are precisely constructed. O lona iʻuga, ua faʻaaogaina i ituaiga eseese o faʻafomaʻi ma militeri.

Nei PCBS e mama, sefe e oʻo i le 60% o le mamafa ma le avanoa.

L maualuga-taimi PCB

Hf PCBS are used in the frequency range of 500MHz to 2GHz. Nei PCBS mafai ona faʻaaogaina i le tele o ituaiga ogaoga taimi masani talosaga, pei o fesoʻotaʻiga sisitema, microwave PCBS, microstrip PCBS, etc.

L Alumini backplane PCB

O nei papatusi o loʻo faʻaaogaina mo maualuga-paoa talosaga ona o le alumini fausaga fesoasoani e faʻasolo vevela. O le PCBS e lagolagoina e le alumini e lauiloa e maualuga maualuga le maʻaʻa ma maualalo le maualuga o le vevela faʻalauteleina, e avea ai i latou ma mea lelei mo faʻaoga e maualuga le faʻapalepale o masini. PCB o loʻo faʻaaogaina mo TAITAIINA ma paoa sapalai.

Manaʻoga mo PCBS o loʻo maua i luga o matata eseese. Aso nei, oe o le a maua ai le tele o lauiloa PCB gaosi oloa ma tufatufaina atu e mafai ona faʻamalieina manaʻoga o le tauvaga fesoʻotaʻi maketi masini. It is always recommended to purchase PCBS for industrial and commercial use from reputable manufacturers and suppliers.
