Nshobora gukaraba cyangwa gusukura PCB ikomeye-flex ukeneye? Ibyo ukeneye kumenya byose

Menyekanisha

mugihe cyo kubungabunga no gukora isuku, abakoresha PCB benshi ntibazi niba ikibaho gikomeye-flex gishobora gukaraba cyangwa gusukurwa nta cyangiritse. Muri iyi nyandiko ya blog, tuzibira muriyi ngingo kugirango tuguhe ubushishozi nubuyobozi. Reka rero dutangire!

Ibibaho byacapwe (PCBs) nibice bigize ibikoresho bya elegitoroniki bigezweho. Zitanga amashanyarazi hamwe ninkunga yibice bitandukanye. Mugihe ikoranabuhanga rigenda ritera imbere, ibishushanyo mbonera bya PCB bigoye kandi byinshi, byagaragaye harimo PCBs ikomeye. Izi mbaho ​​zihuza ibice bikomeye kandi byoroshye kugirango bitange imikorere myiza kandi ikoreshwa.

Wige kubyerekeye ikibaho gikomeye

Mbere yo kuganira kubikorwa byogusukura imbaho ​​zikomeye, birakenewe gusobanukirwa imiterere yabyo. PCBs ya Rigid-flex ikozwe mubice byinshi byibikoresho bikomeye kandi byoroshye, nka FR-4 na polyimide. Izi nzego zirahujwe hakoreshejwe isahani binyuze mu mwobo na flex ihuza. Batanga ibyiza nko kuzigama umwanya, kongera igihe kirekire no kurushaho kwizerwa.

Kuberiki bisukuye imbaho ​​zikomeye?

Kimwe nizindi PCB zose, imbaho ​​zikomeye zirashobora kwegeranya umukungugu, umwanda, nibindi byanduza mugihe cyo gukora cyangwa mugihe cyo gukoresha. Ibi bihumanya birashobora kugira ingaruka kumikorere ya PCB no kuramba. Kubwibyo, isuku isanzwe irakenewe kugirango imikorere ikorwe neza kandi ikumire ibibazo bishobora kuvuka.

Nigute ushobora gusukura imbaho ​​zikomeye

Iyo usukuye imbaho ​​zikomeye, ni ngombwa gukoresha tekinike nuburyo bwiza kugirango wirinde kwangiza ikibaho. Hano hari uburyo bwemewe bwo gusukura izo mbaho:

1. Uburyo bwa Isopropyl inzoga (IPA):Ubu buryo bukubiyemo guhanagura buhoro buhoro hejuru ya PCB hamwe nigitambara kitarimo linti cyangwa ipamba yometse mumuti wa IPA. IPA nikintu gikunze gukoreshwa gikuraho neza umwanda udasize ibisigisigi. Nyamara, ni ngombwa gukoresha umubare muto wa IPA kandi ukirinda ubushuhe burenze kuko bushobora kwinjira mubice byoroshye kandi bigatera kwangirika.

2. Isuku ya Ultrasonic:Isuku ya Ultrasonic nuburyo bukoreshwa mugusukura PCB. Harimo kwibiza PCB mugisubizo cyogusukura mugihe cyo kuvura ultrasonique. Kunyeganyega kwatewe numuraba bikuraho umwanda kandi bigasukura neza ikibaho cyumuzunguruko. Ariko, kwitonda cyane bigomba gukoreshwa mugihe ukoresheje ubu buryo kuko gushyuha cyangwa gukabya bishobora kwangiza ibice byoroshye bya PCB.

3. Gusukura ibyuka byumuyaga:Gusukura icyiciro cya Vapor nubundi buryo bwiza bwo gusukura imbaho ​​zikomeye. Inzira ikubiyemo kwerekana PCB kumashanyarazi isukuye, yegeranye hejuru yikibaho kandi igashonga umwanda. Iri koranabuhanga ritanga isuku yimbitse idatezimbere kwinjira. Ariko, bisaba ibikoresho nubuhanga kabuhariwe, bigatuma bitagerwaho kubakoresha bisanzwe.

Ingamba zo gukurikizwa

Nubwo gusukura imbaho ​​zikomeye ni ngombwa, ni ngombwa kandi gukurikiza ingamba zimwe na zimwe kugirango wirinde kwangirika. Dore zimwe mu nama ugomba kwibuka:

1. Irinde gukoresha ibikoresho bitesha agaciro:Ntugakoreshe ibikoresho byangiza nka brushes cyangwa scrubbing padi kuko bishobora gushushanya cyangwa kwangiza ubuso bworoshye bwa PCB.

2. Ntukibike PCB mumazi:Ntukibike PCB mubisubizo byamazi keretse ukoresheje uburyo bwemewe nko gusukura ultrasonic. Ubushuhe burenze bushobora kwinjira mubice byoroshye kandi bigatera kwangirika.

3. Koresha neza:Buri gihe ujye ukoresha PCB n'amaboko asukuye kandi wirinde kunama cyangwa kugonda ikibaho kurenza imipaka yacyo kuko ibyo bishobora gutera ibibazo cyangwa gucika

Mu mwanzuro:

Muncamake, yego, urashobora gukaraba cyangwa gusukura imbaho ​​zikomeye, ariko ugomba gukurikiza uburyo bwiza nuburyo bwo kwirinda kugirango wirinde ibyangiritse. Isuku isanzwe ifasha kugumana imikorere no kuramba kwizi PCB zateye imbere. Waba wahisemo uburyo bwa IPA, gusukura ultrasonic cyangwa gusukura imyuka, witonde kandi wirinde ubushuhe bukabije cyangwa umuvuduko.

Niba utazi neza uburyo bwoza ikibaho cyoroshye-flex cyangwa gukemura ibindi bibazo byose bijyanye no kubungabunga, birasabwa gushaka ubufasha bwumwuga cyangwa kugisha inama uwakoze PCB. Kugumana PCB yawe isukuye kandi ikabungabungwa neza bizemeza imikorere myiza kandi yizewe yibikoresho bya elegitoroniki.
