PCBs ikomeye-flex PCB irwanya ubushuhe?

Ku bijyanye no kurwanya ubushuhe nubushuhe, umuntu arashobora kwibaza nimba PCBs ikomeye-flex ishobora gukemura iki kibazo. Muri iyi nyandiko ya blog, tuzacengera cyane muriyi nsanganyamatsiko kandi dusuzume ubushuhe nubushuhe bwa PCBs zikomeye.
Ikibaho cyumuzingo cyacapwe (PCBs) nurufatiro rwibikoresho bya elegitoroniki bigezweho, bitanga urubuga rwo guhuza no gushyigikira ibikoresho bya elegitoroniki bitandukanye. Ikoranabuhanga rya PCB ryagiye rihinduka uko imyaka yagiye ihita, kandi kimwe muri ibyo byateye imbere kwari ugutangiza PCB igoye cyane.Iyi mbaho ​​itanga ihinduka rihujwe n’uburinganire bw’imiterere y’imbaho ​​zikomeye, bigatuma zihinduka cyane kandi zikwiriye gukoreshwa mu buryo butandukanye.

Ubushuhe nubushuhe nibintu bisanzwe bibidukikije bishobora kugira ingaruka zikomeye kumikorere no kwizerwa byibikoresho bya elegitoroniki.Guhura nubushuhe birashobora gutera ibibazo bitandukanye, harimo kwangirika, ikabutura yamashanyarazi, no kwangirika kwizuba.Niyo mpamvu, ni ngombwa kwemeza ko PCB zikoreshwa mubikoresho zidashobora guhangana nibi bintu, cyane cyane mubisabwa aho hashobora kuba hari ubushyuhe bwinshi.

Rigid-flex PCB ifite imiterere yihariye kandi ifite urwego runaka rwubushuhe nubushuhe.Izi mbaho ​​zisanzwe zikozwe muburyo bworoshye bwa polyimide yoroheje hamwe na FR-4 igoye, ikora ikibaho gikomeye kandi cyizewe. Igice cya polyimide gitanga ibintu byoroshye, bigatuma PCB yunama cyangwa igoreka nkuko bikenewe, mugihe FR-4 itanga ihame ryimiterere.

Kimwe mu bintu by'ingenzi mu kunoza ubukana bwa PCBs igoye cyane ku butumburuke n'ubushuhe ni ugukoresha polyimide nk'ibikoresho fatizo.Polyimide ni polymer ihamye cyane hamwe no kwinjirira neza kandi kutarwanya neza.Uyu mutungo urinda ubusugire bwa PCB mukurinda igipande cya polyimide kunyunyuza ubuhehere. Byongeye kandi, guhinduka kwa polyimide bituma imbaho ​​zumuzunguruko zihanganira ibidukikije bimwe na bimwe bidatewe nubushuhe.

Byongeye kandi, ikibaho cya flex-flex gikozwe hifashishijwe ikoranabuhanga rigezweho kugirango ryongere ubushobozi bwacyo kandi butangiza amazi.Izi nzira zirimo gukoresha igifuniko cyo gukingira, nk'igifuniko gihuye cyangwa kashe, ikora nk'inzitizi yo kutinjira mu butaka.Iyi myenda yabugenewe kugira ngo ibuze ubushuhe kugera ku bikoresho bya elegitoroniki byoroshye kandi byangiza.

Birakwiye ko tumenya ko nubwo PCBs igoye cyane ifite ubuhehere nubushuhe bukomeye, ntibakingiwe rwose nibi bintu.Ibihe bikabije, kumara igihe kinini mubushuhe bwinshi, cyangwa gufata nabi birashobora gukomeza kugira ingaruka kumikorere yizo mbaho.Nuko rero, ibisabwa by’ibidukikije byihariye bya porogaramu runaka bigomba gusuzumwa kandi PCB ikabikora.

Mugihe cyo gushushanya ubuhehere bwa PCBs igoye, hagomba gutekerezwa ibintu byinshi.Umwanya uhagije hagati yibigize, gufunga neza imiyoboro hamwe na vias, hamwe no gukoresha ubushishozi ibikoresho bitarimo ubushuhe nibimwe mubintu byingenzi bifasha kongera PCB kurwanya ibyo bintu bidukikije. Gukorana cyane nu ruganda rwa PCB rufite uburambe birashobora kwemeza ko igishushanyo mbonera cyakozwe neza kugirango ugere kurwego rukenewe rwubushuhe nubushuhe.

Muri make, kubera imiterere yihariye hamwe no gukoresha ibikoresho bitarinda ubushuhe nka polyimide, imbaho ​​zikomeye-flex zifite ubusanzwe zifite ubushyuhe bwiza kandi butangiza amazi.Zitanga igisubizo cyizewe kubikoresho bya elegitoronike bishobora guhura nibidukikije bibi. Ariko rero, ni ngombwa gusuzuma ibisabwa byihariye bisabwa hanyuma ugashushanya PCB kugirango ubone ubushobozi bwayo bwo guhangana nubushuhe nubushuhe. Mugukora ibi, abakora ibikoresho bya elegitoronike barashobora kwemeza kuramba no kwizerwa kubicuruzwa byabo, ndetse no mubidukikije bisaba.
