Ibice byingenzi bigize Multilayer FPC PCB

Ibice byinshi byuzuza byanditseho imizunguruko (FPC PCBs) nibintu byingenzi bikoreshwa mubikoresho bitandukanye bya elegitoroniki, kuva kuri terefone zigendanwa na tableti kugeza kubikoresho byubuvuzi hamwe na sisitemu yimodoka. Iri koranabuhanga ryateye imbere ritanga uburyo bworoshye bwo guhinduka, kuramba no gukwirakwiza ibimenyetso neza, bigatuma rishakishwa cyane muri iyi si yihuta cyane.Muri iyi nyandiko ya blog, tuzaganira kubice byingenzi bigize FPC PCB igizwe nabantu benshi nakamaro kayo mubikorwa bya elegitoroniki.

1. Substrate yoroheje:

Imiterere ihindagurika ni ishingiro ryabantu benshi FPC PCB.Itanga ihinduka rikenewe hamwe nuburinganire bwubukanishi kugirango bihangane kunama, kuzunguruka no kugoreka bitabangamiye imikorere ya elegitoroniki. Mubisanzwe, ibikoresho bya polyimide cyangwa polyester bikoreshwa nkibikoresho fatizo bitewe nubushyuhe bwiza bwumuriro, kubika amashanyarazi, hamwe nubushobozi bwo gukora ibintu bigenda neza.

2. Urwego ruyobora:

Inzira ziyobora nibintu byingenzi bigize ibice byinshi bya FPC PCB kuko byorohereza urujya n'uruza rw'amashanyarazi mumuzunguruko.Ubusanzwe ibyo bice bikozwe mu muringa, bifite amashanyarazi meza kandi birwanya ruswa. Umuringa wumuringa ushyizwe kumurongo woroheje ukoresheje ibifatika, hanyuma hakurikiraho uburyo bwo gutobora kugirango habeho uburyo bwo kuzenguruka.

3. Urwego rwo gukumira:

Gukingira ibice, bizwi kandi nka dielectric layer, bishyirwa hagati yimyitwarire kugirango birinde ikabutura yamashanyarazi kandi bitange akato.Byakozwe mubikoresho bitandukanye nka epoxy, polyimide cyangwa masike yo kugurisha, kandi bifite imbaraga za dielectric nyinshi hamwe nubushyuhe bwumuriro. Izi nzego zigira uruhare runini mukubungabunga ibimenyetso byerekana ibimenyetso no gukumira inzira nyabagendwa hagati yimyitwarire yimyitwarire.

4. Maskeri yo kugurisha:

Mask ya Solder ni urwego rukingira rushyirwa mubikorwa byogukingira no gukingira birinda imiyoboro migufi mugihe cyo kugurisha kandi ikarinda ibimenyetso byumuringa kubintu bidukikije nkumukungugu, ubushuhe, na okiside.Mubisanzwe ni icyatsi kibisi ariko birashobora no kuza mubindi bisobanuro nkumutuku, ubururu cyangwa umukara.

5. Kurenga:

Coverlay, izwi kandi nka firime ya firime cyangwa igifuniko, ni urwego rwo gukingira rushyirwa hejuru yinyuma ya FPC PCB.Itanga ubundi bwishingizi, kurinda imashini no kurwanya ubushuhe nibindi byanduza. Igipfukisho mubisanzwe gifite gufungura gushyira ibice no kwemerera kubona byoroshye.

6. Isahani y'umuringa:

Isahani y'umuringa ni inzira yo gukwirakwiza amashanyarazi yoroheje y'umuringa ku cyerekezo kiyobora.Iyi nzira ifasha kunoza amashanyarazi, impedance yo hasi, no kuzamura uburinganire bwimiterere rusange ya PCPs nyinshi. Isahani y'umuringa nayo yorohereza ibimenyetso byiza byumuzunguruko mwinshi.

7. Vias:

A unyuze ni umwobo muto wacukuwe unyuze mubice byayobora bya FPC PCB igizwe cyane, ihuza kimwe cyangwa byinshi hamwe.Bemerera guhuza guhuza kandi bigafasha ibimenyetso byerekana inzira hagati yumuzingi utandukanye. Ubusanzwe Vias yuzuyemo umuringa cyangwa paste ikora kugirango umenye neza amashanyarazi.

8. Ibipapuro bigize ibice:

Ibikoresho bigize ibice ni uduce twinshi FPC PCB yagenewe guhuza ibice bya elegitoronike nka résistoriste, capacator, imiyoboro ihuriweho, hamwe nu muhuza.Ubusanzwe aya makariso akozwe mu muringa kandi ahujwe nu murongo wimbere wogukoresha ukoresheje ibicuruzwa cyangwa ibiyobora.

Muri make:

Ikibaho cyoroshye cyacapwe cyumuzunguruko (FPC PCB) nuburyo bugoye bugizwe nibice byinshi byibanze.Ihinduramiterere ryoroshye, ibice byayobora, ibyuma byiziritse, masike yo kugurisha, kurenga, gusiga umuringa, vias hamwe nudupapuro twibikoresho bikorana kugirango bitange amashanyarazi akenewe, guhuza imashini hamwe nigihe kirekire bisabwa nibikoresho bya elegitoroniki bigezweho. Gusobanukirwa nibi bice byingenzi bifasha mugushushanya no gukora ibicuruzwa byiza byo mu rwego rwo hejuru FPC PCBs byujuje ibisabwa byinganda zitandukanye.
