Hariho ubwoko bwinshi bwibibaho byumuzunguruko ku isoko, kandi amagambo yumwuga aratandukanye, muribwo ikibaho cya fpc gikoreshwa cyane, ariko abantu benshi ntibazi byinshi kubuyobozi bwa fpc, none ubuyobozi bwa fpc busobanura iki?

1, ikibaho cya fpc nacyo cyitwa "flexible circuit board", nimwe mubibaho byacapwe na PCB byacapwe, ni ubwoko bwokoresha ibikoresho byo kubika insimburangingo, nka: polyimide cyangwa polyester, hanyuma binyuze muburyo budasanzwe bukozwe mubibaho byacapwe. Ubucucike bw'insinga z'uru rubaho ruzenguruka muri rusange ni hejuru cyane, ariko uburemere buzaba bworoshye, umubyimba uzaba muto, kandi ufite imikorere ihindagurika, kimwe no kunama neza.

2, ikibaho cya fpc nubuyobozi bwa PCB ni itandukaniro rinini. Substrate yinama ya fpc muri rusange ni PI, irashobora rero kugororwa uko bishakiye, guhindagurika, nibindi, mugihe substrate yubuyobozi bwa PCB muri rusange ari FR4, ntabwo rero ishobora kugororwa uko yishakiye. Kubwibyo, gukoresha no gusaba imirima yubuyobozi bwa fpc nubuyobozi bwa PCB nabyo biratandukanye cyane.

3, kubera ko ikibaho cya fpc gishobora kugororwa no guhindagurika, ikibaho cya fpc gikoreshwa cyane mumwanya ugomba guhindurwa inshuro nyinshi cyangwa guhuza ibice bito. Ubuyobozi bwa PCB burakomeye, burakoreshwa cyane ahantu hamwe na hamwe aho bidakeneye kunama kandi imbaraga zirakomeye.

4, ikibaho cya fpc gifite ibyiza byubunini buto, uburemere bworoshye, kuburyo bushobora kugabanya neza ingano yibicuruzwa bya elegitoronike ni bito cyane, bityo bikoreshwa cyane mu nganda za terefone zigendanwa, inganda za mudasobwa, inganda za televiziyo, inganda za kamera za digitale n’izindi nganda ntoya, ugereranije n’inganda zikoresha ibikoresho bya elegitoroniki.

5, ikibaho cya fpc ntigishobora kugororwa gusa, ahubwo gishobora no gukomeretsa uko bishakiye cyangwa kugapfundikirwa hamwe, kandi birashobora no gutegurwa kubuntu ukurikije ibikenewe byimiterere. Mu mwanya wibice bitatu, ikibaho cya fpc nacyo gishobora kwimurwa uko bishakiye cyangwa telesikopi, kugirango intego yo kwishyira hamwe igerweho hagati yinsinga ninteko yibigize.

Niki firime yumye PCB?

1, PCB imwe

Isahani fatizo ikozwe mu mpapuro za fenol y'umuringa wometse ku rubaho (impapuro fenol nk'ifatizo, ushyizweho na feza y'umuringa) hamwe n'impapuro Epoxy y'umuringa. Byinshi muribi bikoreshwa mubicuruzwa byamashanyarazi murugo nka radio, ibikoresho bya AV, ubushyuhe, firigo, imashini imesa, nimashini zubucuruzi nka printer, imashini zicuruza, imashini zumuzunguruko, nibikoresho bya elegitoroniki.

2, impande zombi PCB

Ibikoresho fatizo ni Ikirahure-Epoxy y'umuringa wacuzwe, Ikibaho cya GlassComposite, hamwe n'impapuro Epoxy y'umuringa. Byinshi muribi bikoreshwa muri mudasobwa kugiti cye, ibikoresho bya elegitoroniki bya muzika, terefone ikora imirimo myinshi, imashini zikoresha ibikoresho bya elegitoronike, ibyuma bya elegitoroniki, ibikinisho bya elegitoronike, n'ibindi. Kubijyanye na Glass benzene resin y'umuringa wa laminates, Glass polymer umuringa wa laminate ikoreshwa cyane mu mashini zitumanaho, imashini zitanga amakuru kuri satelite, ndetse n’imashini zitumanaho zigendanwa cyane, kandi na byo birumvikana ko,

3, 3-4 ibice bya PCB

Ibikoresho fatizo ahanini ni Glass-Epoxy cyangwa benzene resin. Ahanini ikoreshwa muri mudasobwa bwite, Me (ibikoresho bya elegitoroniki yubuvuzi, ibikoresho bya elegitoroniki yubuvuzi), imashini zipima, imashini zipima semiconductor, imashini ya NC (NumericControl, igenzura ryimibare), imashini ya elegitoronike, imashini zitumanaho, imbaho ​​zumuzunguruko, amakarita ya IC, nibindi, hariho kandi ibirahuri bya sintetike y'umuringa byashyizwe kumurongo nkibikoresho byinshi bya PCB, cyane cyane byibanda kubiranga uburyo bwiza bwo gutunganya.

4,6-8 ibice bya PCB

Ibikoresho fatizo biracyashingira kuri GLASS-epoxy cyangwa Glass benzene resin. Ikoreshwa muburyo bwa elegitoronike, imashini zipima semiconductor, mudasobwa ziciriritse ziciriritse, EWS (EngineeringWorkStation), NC nizindi mashini.

5, ibice birenga 10 bya PCB

Substrate ikozwe cyane cyane muri Glass benzene resin, cyangwa GLASS-epoxy nkibikoresho byinshi bya PCB substrate. Gukoresha ubu bwoko bwa PCB birihariye, ibyinshi muri byo ni mudasobwa nini, mudasobwa yihuta, imashini zitumanaho, nibindi, cyane cyane ko bifite imiterere yumurongo mwinshi hamwe nubushyuhe bwo hejuru cyane.

6, ibindi bikoresho bya PCB

Ibindi bikoresho bya PCB nibikoresho bya aluminium, substrate yicyuma nibindi. Umuzunguruko ukorwa kuri substrate, inyinshi murizo zikoreshwa mumodoka ihinduka (moteri nto). Mubyongeyeho, hariho PCB yoroheje (FlexiblPrintCircuitBoard), umuzenguruko ukorwa kuri polymer, polyester nibindi bikoresho byingenzi, birashobora gukoreshwa nkigice kimwe, ibice bibiri, kugeza kubibaho byinshi. Ikibaho cyumuzunguruko cyoroshye gikoreshwa cyane cyane mubice byimukanwa bya kamera, imashini za OA, nibindi, hamwe nisano iri hagati ya PCB ikomeye cyangwa guhuza neza guhuza PCB ikomeye na PCB yoroshye, nkuburyo bwo guhuza guhuza bitewe na elastique nyinshi, imiterere yayo iratandukanye.

Ikibaho kinini kandi icyapa giciriritse kandi kinini

Ubwa mbere, ibice byinshi byumuzunguruko wa PCB bikoreshwa mubice ki?

Ikibaho cyumuzunguruko wa PCB gikoreshwa cyane mubikoresho byitumanaho, ibikoresho byubuvuzi, kugenzura inganda, umutekano, ibikoresho bya elegitoroniki, indege, imirima ya mudasobwa; Nka "mbaraga nyamukuru" muriyi nzego, hamwe no gukomeza kwiyongera kwimikorere yibicuruzwa, imirongo myinshi kandi yuzuye, ibisabwa bijyanye nisoko ryujuje ubuziranenge niko bigenda byiyongera kandi hejuru, kandi abakiriya basaba imbaho ​​ziciriritse za TG ziciriritse kandi ndende.

Icya kabiri, umwihariko wibice byinshi byumuzunguruko wa PCB

Ubuyobozi busanzwe bwa PCB buzagira deformasiyo nibindi bibazo mubushyuhe bwinshi, mugihe imiterere ya mashini n amashanyarazi nayo ishobora kugabanuka cyane, bikagabanya ubuzima bwa serivisi kubicuruzwa. Umwanya wo gukoresha urwego rwububiko bwa PCB urwego rusanzwe ruherereye mubikorwa byikoranabuhanga byo mu rwego rwo hejuru, bisaba mu buryo butaziguye ko inama y'ubutegetsi ifite umutekano muke, irwanya imiti myinshi, kandi ishobora kwihanganira ubushyuhe bwinshi, ubuhehere bwinshi n'ibindi.

Kubwibyo, umusaruro wibibaho byinshi bya PCB ukoresha byibura ibyapa bya TG150, kugirango harebwe niba ikibaho cyumuzunguruko kigabanywa nimpamvu zituruka mugikorwa cyo gusaba kandi kongerera igihe cyibicuruzwa.

Icya gatatu, ubwoko bwa TG bwo hejuru burahamye kandi bwizewe

Agaciro ka TG ni akahe?

Agaciro ka TG: TG nubushyuhe bwo hejuru aho urupapuro ruguma rukomeye, kandi agaciro ka TG bivuga ubushyuhe aho polymer amorphous (nayo irimo igice cya amorphous igice cya kristaline polymer) iva mubirahuri ikajya muri reta ya elastike (leta ya rubber).

Agaciro TG nubushyuhe bukomeye aho substrate ishonga kuva ikomeye kugeza kumazi.

Urwego rwagaciro rwa TG rufitanye isano itaziguye no gutuza no kwizerwa kubicuruzwa bya PCB, kandi hejuru ya TG agaciro kibaho, niko gukomera no kwizerwa.

Urupapuro rwo hejuru rwa TG rufite ibyiza bikurikira:

1) Kurwanya ubushyuhe bwinshi, bushobora kugabanya kureremba hejuru ya PCB mugihe gishushe gishyushye, gusudira hamwe nubushyuhe bwumuriro.

2) Coefficente yo kwagura ubushyuhe buke (CTE yo hasi) irashobora kugabanya ubukana buterwa nubushyuhe, kandi bikagabanya kuvunika kwumuringa kumpande yumwobo watewe no kwaguka kwinshi, cyane cyane mubibaho bya PCB bifite ibice umunani cyangwa birenga, imikorere yibisate byacishijwe mu mwobo iruta iy'ibibaho bya PCB bifite agaciro rusange ka TG.

3) Ifite imiti irwanya imiti, kuburyo ikibaho cya PCB gishobora gushiramo uburyo bwo kuvura amazi n’ibisubizo byinshi by’imiti, imikorere yacyo iracyari nziza.
