FR4 na Polyimide: Nibihe bikoresho bikwiranye nizunguruka zoroshye?

Muri iyi blog, tuzasesengura itandukaniro riri hagati ya FR4 nibikoresho bya polyimide ningaruka zabyo mubishushanyo mbonera bya flex n'imikorere.

Inzira zoroshye, zizwi kandi nk'imashini zicapye zoroshye (FPC), zahindutse igice cy'ibikoresho bya elegitoroniki bigezweho kubera ubushobozi bwo kugoreka no kugoreka. Iyi miyoboro ikoreshwa cyane mubisabwa nka terefone zigendanwa, ibikoresho byambarwa, ibikoresho bya elegitoroniki, n'ibikoresho by'ubuvuzi. Ibikoresho bikoreshwa mubikorwa byoroshye byumuzunguruko bigira uruhare runini mubikorwa byabo no mumikorere. Ibikoresho bibiri bikunze gukoreshwa muburyo bworoshye ni FR4 na polyimide.

FR4 bisobanura Flame Retardant 4 kandi ni fiberglass ikomezwa na epoxy laminate. Ikoreshwa cyane nkibikoresho fatizo kubibaho byacapwe byizunguruka (PCBs).Ariko, FR4 irashobora kandi gukoreshwa mumuzunguruko woroshye, nubwo ufite aho ugarukira. Ibyiza byingenzi bya FR4 nimbaraga zayo zikomeye kandi zihamye, bigatuma zikoreshwa mubisabwa aho gukomera ari ngombwa. Ntabwo kandi bihendutse ugereranije nibindi bikoresho bikoreshwa mumuzunguruko woroshye. FR4 ifite ibikoresho byiza byo gukwirakwiza amashanyarazi kandi birwanya ubushyuhe bwiza. Ariko, kubera gukomera kwayo, ntabwo ihinduka nkibindi bikoresho nka polyimide.

Polyimide, kurundi ruhande, ni polymer ikora cyane itanga ihinduka ridasanzwe. Nibikoresho bya termoset bishobora kwihanganira ubushyuhe bwinshi kandi bikwiranye nibisabwa bisaba kurwanya ubushyuhe.Polyimide ikunze guhitamo gukoreshwa mumuzunguruko woroshye bitewe nubworoherane bwayo kandi burambye. Irashobora kugoreka, kugoreka no kugundwa bitagize ingaruka kumikorere yumuzunguruko. Polyimide ifite kandi ibikoresho byiza byo gukwirakwiza amashanyarazi hamwe na dielectric idahoraho, ifitiye akamaro porogaramu nyinshi. Nyamara, polyimide muri rusange ihenze kuruta FR4 kandi imbaraga zayo za mashini zishobora kuba nke ugereranije.

Byombi FR4 na polyimide bifite inyungu zabo nimbogamizi mugihe cyo gukora.Ubusanzwe FR4 ikorwa hifashishijwe uburyo bwo gukuramo aho umuringa urenze uva kure kugirango ukore icyerekezo cyizunguruka. Iyi nzira irakuze kandi ikoreshwa cyane mubikorwa bya PCB. Ku rundi ruhande, Polyimide, ikunze gukorwa cyane hifashishijwe uburyo bwo kongeramo ibintu, bikubiyemo gushyiramo ibice bito byumuringa kuri substrate kugirango yubake imiterere yumuzunguruko. Inzira ituma imiyoboro iyobora neza hamwe nu ntera ikarishye, bigatuma ikwirakwira cyane.

Kubijyanye nimikorere, guhitamo hagati ya FR4 na polyimide biterwa nibisabwa byihariye bya porogaramu.FR4 nibyiza kubisabwa aho gukomera nimbaraga za mashini ari ngombwa, nka electronics yimodoka. Ifite ubushyuhe bwiza kandi irashobora kwihanganira ubushyuhe bwo hejuru. Nubwo bimeze bityo ariko, guhinduka kwayo ntigukwiye gukoreshwa mubisabwa bisaba kunama cyangwa kugundwa, nkibikoresho byambara. Polyimide, kurundi ruhande, iruta izindi porogaramu zisaba guhinduka no kuramba. Ubushobozi bwayo bwo kwihanganira kunama inshuro nyinshi bituma biba byiza mubikorwa birimo kugenda bikomeza cyangwa kunyeganyega, nkibikoresho byubuvuzi hamwe na elegitoroniki yo mu kirere.

Muri make, guhitamo ibikoresho bya FR4 hamwe na polyimide mumuzunguruko woroshye biterwa nibisabwa byihariye bya porogaramu.FR4 ifite imbaraga zo gukanika kandi zihamye, ariko ntizihinduka. Ku rundi ruhande, Polyimide itanga uburyo bworoshye kandi burambye ariko birashobora kuba bihenze cyane. Gusobanukirwa itandukaniro riri hagati yibi bikoresho ningirakamaro mugushushanya no gukora imiyoboro yoroheje yujuje ibisabwa nibikorwa. Yaba telefone igendanwa, ishobora kwambarwa cyangwa igikoresho cyubuvuzi, guhitamo ibikoresho bikwiye ningirakamaro kugirango intsinzi yumuzunguruko woroshye.
