Fuafuaga lolomi laupapa matagaluega (PCB) o se masani masani gaioiga mo tele eletise inisinia (EE). E ui lava i le tele o tausaga o le poto masani mamanu PCB, fatuina maualuga-lelei faʻatinoina-tulia PCB ata e le faigofie. E tele mea e tatau ona mafaufau i ai, ma o le peleti mea o se tasi o latou. O mea masani na faʻaaoga e fai ai PCBS e taua tele. I luma o gaosiga, o meatotino o mea i vaega eseese e tatau ona mafaufauina, e pei o fetuʻutuʻunaʻi, vevela teteʻe, dielectric tumau, dielectric malosi, malosi malosi, pipiʻi ma isi. O le faʻatinoina ma le tuʻufaʻatasia o se matagaluega laupapa e faʻalagolago atoa i mea faʻaaoga. Lenei tusitusiga toe suʻesuʻe atili PCB mea. So stay tuned for more information.

What types of materials are used in PCB manufacturing?

O le lisi lea o mea taua e faʻaaoga e fai ai laupapa laupapa. Seʻi o tatou vaʻavaʻai i ai.

Fr-4: FR e puʻupuʻu mo FIRE RETARDENT. O le sili ona masani ona faʻaaogaina PCB mea mo ituaiga uma o PCB gaosiga. Fau tioata faʻamalosia epoxy laminate FR-4 e faia faʻaaogaina fiberglass lalagaina ie ma apamemea resin resin. O lenei mea e taʻutaʻua aua e maua ai eletise sili faʻalelei ma e iai le lelei o le masini. O lenei mea e maua ai le maualuga maualuga malosi malosi. E lauiloa ona o lona gaosiga lelei ma suamalie susu.

Fr-5: O le substrate e faia i le tioata alava faʻamalosia mea ma se epoxy resin faila. This is a good choice for multi-layer circuit board design. E lelei lona faʻatinoina i le uʻamea leai se taʻimua ma sili atu ona lelei mea totino i le maualuga o le vevela. E maitauina mo lona maualalo suamalie susu, vailaʻau teteʻe, sili atu eletise meatotino ma sili malosi.

Fr-1 ma le FR-2: E aofia ai pepa ma phenolic compound ma e fetaui lelei mo le tasi-vaega circuit board design. O mea uma e lua e tutusa a latou meatotino, ae o le FR2 ei ai le maualalo o tioata suiga suiga nai lo FR1.

Cem-1: O lenei mea aofia ai i le kulupu o tuʻufaʻatasiga epoxy mea (CEM). O le seti aofia ai epoxy gaosia resin, fau tioata ie ma lē fiberglass autu. O le mea, faʻaaogaina i le tasi-itu laupapa taʻamilosaga, e le taugata ma mumū retardant. It is famous for its excellent mechanical and electrical performance.

Cem-3: Similar to CEM-1, this is another composite epoxy material. E i ai afi retardant meatotino ma e masani ona faʻaaogaina mo lua-itu laupapa matagaluega. It is less mechanically strong than FR4, but cheaper than FR4. Therefore, it is a good alternative to FR4.

Apamemea: Apamemea o le muamua filifiliga i le gaosia o nofofua ma multilayer matagaluega laupapa. E mafua ona e maua ai maualuga maualuga tulaga, maualuga vevela ma eletise faʻatinoina ma maualalo vailaʻau reactivity.

Maualuga Tg: Maualuga Tg faʻaalia maualuga tioata suiga suiga. Lenei mea PCB mea lelei mo laupapa i manaʻoga talosaga. Tg mea e iai le maualuga o le vevela umi ma le umi le tumau delamination umi.

Rogers: E masani ona taʻua o le RF, o lenei mea e lauiloa mo lona tuʻufaʻatasia ma FR4 laminates. Ona o lona maualuga tigaina conductivity ma pulea impedance, e mafai ona faigofie machined laupapa matagaluega-saoloto.

Alumini: O lenei mea malleable ma malleable PCB mea puipuia laupapa ‘apamemea mai overheating. Na filifilia muamua lava mo lona agavaʻa e faʻateʻa ese vave le vevela.

Halogen-leai se alumini: O lenei uʻamea e fetaui lelei mo le siosiomaga faʻauo apalai. O le Halogen-leai alumini ua faʻaleleia atili le dielectric faifai pea ma le susu diffusivity.

I le aluga o tausaga, ua maua PCBS maoae lauiloa ma maua ai le tele o ituaiga o talosaga i pisinisi e manaʻomia matagaluega faigata. O le mea lea, filifilia le mea saʻo PCB mea taua tele, aua e afaina ai e le gata o gaioiga ma uiga, ae faʻapena foi le tau atoa o le laupapa. Filifili mea faʻavae i luga o talosaga manaʻoga, siosiomaga mea, ma isi tapulaʻa feagai ma le PCB.
