2-Ibice byoroshye PCB - Igishushanyo cya FPC na Prototyping

Intangiriro

Ikibaho cyoroshye cyacapishijwe imbaho ​​(FPCs) zirahindura inganda za elegitoroniki, zitanga ibintu bitagereranywa kandi byoroshye.Mugihe icyifuzo cyibikoresho bya elegitoroniki byoroheje kandi byoroheje bikomeje kwiyongera, FPCs igira uruhare runini mugutanga ibisubizo bishya kandi byoroshye.Mu bwoko butandukanye bwa FPC, PCBs 2-igizwe na PCB igaragara cyane kubikorwa byayo no gukoreshwa mubikorwa bitandukanye byinganda.Muri ubu buyobozi bwuzuye, tuzasesengura igishushanyo mbonera na prototyping ya 2-layer PCBs yoroheje, twibanda kubikorwa byabo, ibikoresho, ibisobanuro, hamwe nubuso bwuzuye.

Ubwoko bwibicuruzwa:2-Igice cyoroshye PCB

PCB ya 2-layer flex PCB, izwi kandi nkimpande zombi zuzunguruka, ni ikibaho cyanditse cyumuzunguruko cyoroshye kigizwe nibice bibiri byayobora bitandukanijwe na dielectric layer.Iboneza ritanga abashushanya ibintu byoroshye guhuza inzira kumpande zombi za substrate, bigatuma ibishushanyo mbonera binini bikora.Ubushobozi bwo gushiraho ibice kumpande zombi zubuyobozi bituma 2-layer flex PCBs nziza kubisabwa bisaba ubucucike bwibice byinshi hamwe nimbogamizi zumwanya.

Porogaramu

Ubwinshi bwa 2-layer flex PCBs ituma bikwiranye nibikorwa bitandukanye mubikorwa bitandukanye.Imwe mumikorere igaragara ya 2-layer flexible PCB iri murwego rwa electronics yimodoka.Mu nganda zitwara ibinyabiziga, umwanya hamwe no kuzigama ibiro ni ibintu byingenzi, kandi ibice 2 bya flex PCBs itanga ihinduka kugirango ibyo bisabwa.Zikoreshwa muri sisitemu yo kugenzura ibinyabiziga, sensor, kumurika, sisitemu ya infotainment, nibindi byinshi.Inganda zitwara ibinyabiziga zishingiye ku kuramba no kwizerwa bya 2-layer PCBs kugirango yizere imikorere ihamye mubidukikije.

Usibye porogaramu zikoresha amamodoka, ibice 2 byoroshye PCBs bikoreshwa cyane mubikoresho bya elegitoroniki, ibikoresho byubuvuzi, icyogajuru nibikoresho byinganda.Ubushobozi bwabo bwo kumenyera imiterere idasanzwe, kugabanya ibiro no kongera ubwizerwe bituma baba ingenzi mubicuruzwa bitandukanye bya elegitoroniki.

Ibikoresho

2-Imirongo ihindagurika ya PCB Guhitamo ibikoresho nibyingenzi muguhitamo imikorere yubuyobozi, kwiringirwa, no gukora.Ibikoresho byibanze bikoreshwa mukubaka ibice 2 byoroshye PCB harimo firime ya polyimide (PI), umuringa, hamwe na adhesives.Polyimide ni substrate yibikoresho byo guhitamo bitewe nubushyuhe buhebuje bwumuriro, guhinduka hamwe nubushyuhe bwo hejuru.Umuringa wumuringa ukoreshwa nkibikoresho bitwara ibintu, bifite uburyo bwiza kandi bworoshye.Ibikoresho bifata neza bikoreshwa muguhuza ibice bya PCB hamwe, bigahuza imashini no gukomeza ubusugire bwumuzingi.

Ubugari bwumurongo, intera yumurongo hamwe nubunini bwikibaho

Mugushushanya ibice 2 byoroshye PCB, ubugari bwumurongo, intera yumurongo hamwe nubugari bwibibaho nibintu byingenzi, bigira ingaruka kuburyo butaziguye kumikorere no gukora byubuyobozi.Ubugari busanzwe bwumurongo hamwe numurongo utandukanijwe kuri 2-ibice byoroshye PCBs bisobanurwa nka 0.2mm / 0.2mm, byerekana ubugari ntarengwa bwimiterere yimyitwarire hamwe nintera iri hagati yabyo.Ibipimo nibyingenzi kugirango hamenyekane neza ibimenyetso byuzuye, kugenzura inzitizi, no kugurisha byizewe mugihe cyo guterana.Byongeye kandi, uburebure bwikibaho bwa 0.2mm +/- 0.03mm bugira uruhare runini mukumenya guhinduka, kugoreka radiyo hamwe nubukanishi rusange bwa tekinike ya PC ya layer 2.

Ingano ntoya nubunini bwo kuvura

Kugera kubunini bwuzuye kandi buhoraho nibyingenzi muburyo bwa 2-byoroshye PCB igishushanyo, cyane cyane ukurikije miniaturisiyonike ya electronics.Ingano ntarengwa yerekana umwobo wa 0.1 mm yerekana ubushobozi bwa 2-layer flex PCBs kugirango yakire ibice bito kandi bipakiye cyane.Mubyongeyeho, kuvura hejuru bigira uruhare runini mugutezimbere amashanyarazi no kugurishwa kwa PCBs.Electroless Nickel Immersion Zahabu (ENIG) ifite umubyimba wa 2-3uin ni amahitamo asanzwe kuri PCBs igizwe na layer 2 kandi itanga uburyo bwiza bwo kurwanya ruswa, kureshya, no kugurisha.Ubuvuzi bwa ENIG bufite akamaro kanini mugushoboza ibice byiza no kwemeza kugurisha neza.

Impedance no kwihanganirana

Muburyo bwihuse bwa digitale hamwe na analogi, kugenzura inzitizi ningirakamaro mukubungabunga ibimenyetso byerekana ibimenyetso no kugabanya kugoreka ibimenyetso.Nubwo nta ndangagaciro zihariye zitangwa, ubushobozi bwo kugenzura impedance ya 2-flex ya PCB ningirakamaro kugirango huzuzwe ibisabwa byimikorere ya elegitoroniki.Byongeye kandi, kwihanganira bisobanuwe nka ± 0.1mm, bivuga gutandukana byemewe kurwego rwo gukora.Kugenzura kwihanganira gukomera ni ngombwa kugirango hamenyekane neza kandi bihamye mu bicuruzwa byanyuma, cyane cyane iyo ukorana na mikoro-miterere n'ibishushanyo mbonera.

2 Inzira Yoroshye ya PCB Gahunda yo Kwandika

Prototyping nicyiciro gikomeye muburyo bwa 2-flex flex ya PCB, yemerera abashushanya kugenzura igishushanyo, imikorere, nibikorwa mbere yo gukomeza umusaruro wuzuye.Inzira ya prototyping ikubiyemo intambwe nyinshi zingenzi, zirimo kugenzura ibishushanyo, guhitamo ibikoresho, gukora, no kugerageza.Kugenzura ibishushanyo mbonera byemeza ko inama yujuje ibyangombwa bisabwa n'imikorere, mugihe guhitamo ibikoresho birimo guhitamo substrate ikwiye, ibikoresho bitwara no kuvura hejuru hashingiwe kubisabwa nibikorwa.

Guhimba porotipiki ya PCB igizwe na 2 igizwe no gukoresha ibikoresho byihariye hamwe nuburyo bwo gukora substrate yoroheje, gukoresha uburyo bwo kuyobora, no guteranya ibice.Ubuhanga buhanitse bwo gukora nka laser yo gucukura, gutoranya guhitamo no kugenzura inzira ya impedance ikoreshwa kugirango ugere kubikorwa bikenewe nibikorwa biranga.Iyo prototype imaze gukorwa, hakorwa igeragezwa rikomeye kandi ryemezwa kugirango harebwe imikorere y'amashanyarazi, imashini ihindagurika kandi yizewe mubihe bitandukanye bidukikije.Ibitekerezo bivuye kuri prototyping stade bifasha gushushanya neza no kunoza, amaherezo bikavamo igishushanyo gikomeye kandi cyizewe cyibice 2 byoroshye bya PCB byiteguye kubyara umusaruro.

Umwanzuro

Muri make, ibice 2 bya flex PCBs byerekana ibisubizo bigezweho kubishushanyo mbonera bya elegitoroniki bigezweho, bitanga ihinduka ntagereranywa, kwizerwa no gukora.Ubwinshi bwibikorwa, ibikoresho bigezweho, ibisobanuro birambuye hamwe na prototyping inzira bituma iba ikintu cyingenzi mubikorwa bya elegitoroniki.Mugihe ikoranabuhanga rikomeje gutera imbere, PCBs igizwe n’ibice 2 nta gushidikanya ko izagira uruhare runini mu gutuma ibicuruzwa bya elegitoroniki bishya byujuje ibyifuzo by’isi yahujwe.Haba mumodoka, ibikoresho bya elegitoroniki byabaguzi, ibikoresho byubuvuzi cyangwa icyogajuru, igishushanyo mbonera hamwe na prototyping ya 2-layer PCBs byoroshye ni ngombwa kugirango utere umurongo ukurikira wo guhanga udushya twa elegitoroniki.
