Bitewe nuburyo bugoye hamwe nibiranga bidasanzwe,umusaruro wibibaho bigoye bisaba inzira zidasanzwe zo gukora. Muri iyi nyandiko ya blog, tuzasesengura intambwe zinyuranye zigira uruhare mu gukora ibi bikoresho bigezweho bya PCB byoroshye kandi tunerekana ibitekerezo byihariye bigomba kwitabwaho.
Ikibaho cyumuzingo cyacapwe (PCBs) ninkingi ya elegitoroniki igezweho. Nizo shingiro ryibikoresho bya elegitoronike bihujwe, bikora igice cyingenzi cyibikoresho byinshi dukoresha buri munsi. Nka tekinoroji igenda itera imbere, niko hakenewe ibisubizo byoroshye kandi byoroshye. Ibi byatumye habaho iterambere rya PCBs zikomeye, zitanga uburyo bwihariye bwo gukomera no guhinduka ku kibaho kimwe.
Shushanya ikibaho gikomeye
Intambwe yambere kandi yingenzi muburyo bukomeye bwo gukora ni igishushanyo. Gushushanya ikibaho gikomeye gisaba gutekereza cyane kumiterere yumuzunguruko rusange no gushyira ibice. Ahantu horoheje, kugoreka radii no mubice bigomba gusobanurwa mugihe cyicyiciro cyo gushushanya kugirango imikorere ikwiye irangire.
Ibikoresho bikoreshwa muri PCBs bigomba guhinduka neza kugirango byuzuze ibisabwa byihariye bya porogaramu. Gukomatanya ibice bikomeye kandi byoroshye bisaba ko ibikoresho byatoranijwe bifite uburyo bwihariye bwo guhuza no gukomera. Mubisanzwe byoroshye guhinduranya nka polyimide na thin FR4 bikoreshwa, kimwe nibikoresho bikomeye nka FR4 cyangwa ibyuma.
Gushyira kumurongo no Gutegura Substrate yo gukora flex pcb ikomeye
Igishushanyo kimaze kurangira, inzira yo gutondekanya ibice iratangira. Rigid-flex yacapishijwe imbaho zumuzunguruko zigizwe nibice byinshi bya substrate ikomeye kandi yoroheje ihujwe hamwe ikoresheje imiti yihariye. Uku guhuza kwemeza ko ibice bikomeza kuba byiza ndetse no mubihe bigoye nko kunyeganyega, kunama no guhinduka kwubushyuhe.
Intambwe ikurikira mubikorwa byo gukora ni ugutegura substrate. Ibi birimo gusukura no kuvura hejuru kugirango hamenyekane neza. Igikorwa cyo gukora isuku gikuraho ibintu byose byanduza bishobora kubangamira uburyo bwo guhuza, mugihe ubuvuzi bwo hejuru bwongera guhuza hagati yinzego zitandukanye. Tekinike nko kuvura plasma cyangwa imiti yimiti ikoreshwa kenshi kugirango igere kubintu bifuza.
Igishushanyo cyumuringa hamwe nuburyo bwimbere kugirango habeho ibintu byoroshye byumuzunguruko
Nyuma yo gutegura substrate, komeza inzira yo gushushanya umuringa. Ibi bikubiyemo gushira umuringa muto cyane wumuringa kuri substrate hanyuma ugakora progaramu ya fotolitografiya kugirango ukore icyerekezo cyizunguruka. Bitandukanye na PCBs gakondo, PCBs igoye gusuzuma neza igice cyoroshye mugihe cyo gushushanya. Hagomba kwitonderwa byumwihariko kugirango wirinde guhangayika bitari ngombwa cyangwa kwangiriza ibice byoroshye byubuyobozi bwumuzunguruko.
Igishushanyo cy'umuringa kimaze kurangira, imiterere y'imbere iratangira. Muri iyi ntambwe, ibice bikomeye kandi byoroshye byahujwe kandi isano hagati yabyo irashirwaho. Ibi mubisanzwe bigerwaho hifashishijwe vias, itanga amashanyarazi hagati yinzego zitandukanye. Vias igomba gutegurwa neza kugirango ihuze neza ninama, urebe ko itabangamira imikorere rusange.
Kumurika no gushiraho ibice byo hanze kugirango bikorwe-flex pcb
Iyo urwego rwimbere rumaze gushingwa, inzira yo kumurika iratangira. Ibi bikubiyemo gutondekanya ibice byihariye no kubishyushya ubushyuhe nigitutu. Ubushyuhe nigitutu bikora bifata kandi bigateza imbere guhuza ibice, bigakora imiterere ikomeye kandi iramba.
Nyuma yo kumurika, inzira yo gushiraho ibice byo hanze iratangira. Ibi bikubiyemo gushyira umuringa muto cyane wumuringa hejuru yinyuma yumuzunguruko, hanyuma hagakurikiraho uburyo bwo gufotora kugirango habeho uburyo bwa nyuma bwumuzunguruko. Gushiraho urwego rwinyuma bisaba uburinganire nukuri kugirango harebwe neza guhuza imiterere yumuzingi hamwe nigice cyimbere.
Gucukura, gusya no kuvura hejuru kubikorwa byoroshye bya pcb
Intambwe ikurikiraho mubikorwa byo gukora ni ugucukura. Ibi birimo gucukura umwobo muri PCB kugirango ibice byinjizwemo kandi amashanyarazi akorwe. Gucukura Rigid-flex PCB bisaba ibikoresho kabuhariwe bishobora kwakira ubunini butandukanye hamwe nimbaho zuzunguruka.
Nyuma yo gucukura, amashanyarazi arakorwa kugirango yongere ubushobozi bwa PCB. Ibi bikubiyemo gushira icyuma cyoroshye (ubusanzwe umuringa) kurukuta rwumwobo. Ibyobo byashizweho bitanga uburyo bwizewe bwo gushiraho amashanyarazi hagati yinzego zitandukanye.
Hanyuma, kurangiza hejuru birakorwa. Ibi bikubiyemo gukoresha igipfundikizo gikingira hejuru yumuringa wagaragaye kugirango wirinde kwangirika, kongera imbaraga, no kunoza imikorere yubuyobozi. Ukurikije ibisabwa byihariye bya porogaramu, uburyo butandukanye bwo kuvura burahari, nka HASL, ENIG cyangwa OSP.
Kugenzura ubuziranenge no kugerageza kubikorwa bya flex byacapwe byumuzunguruko
Mubikorwa byose byo gukora, ingamba zo kugenzura ubuziranenge zishyirwa mubikorwa kugirango harebwe ibipimo bihanitse byo kwizerwa no gukora. Koresha uburyo bwo kwipimisha buhanitse nko kugenzura optique (AOI), kugenzura X-ray no gupima amashanyarazi kugirango umenye inenge zose cyangwa ibibazo biri mukibaho cyumuzunguruko cyarangiye. Byongeye kandi, igeragezwa rikomeye ryibidukikije no kwizerwa rikorwa kugirango harebwe niba PCBs idashobora kwihanganira ibihe bitoroshye.
Muri make
Umusaruro wibibaho bigoye bisaba inzira zidasanzwe zo gukora. Imiterere igoye hamwe nibidasanzwe biranga imbaho zambere zumuzunguruko bisaba gutekereza neza, guhitamo ibikoresho neza hamwe nintambwe yihariye yo gukora. Mugukurikiza ubu buryo bwihariye bwo gukora, abakora ibikoresho bya elegitoroniki barashobora gukoresha imbaraga zose za PCBs zikomeye kandi bakazana amahirwe mashya kubikoresho bya elegitoroniki, byoroshye kandi byoroshye.
