Gukemura ibibazo bya EMI muburyo bworoshye bwa PCB kubihimbano byihuta kandi byihuse

Guhindura imashanyarazi byoroshye gukoreshwa cyane munganda zitandukanye bitewe nibyiza byinshi nko guhinduka, kuremereye, guhuzagurika no kwizerwa cyane. Ariko, kimwe nizindi terambere ryiterambere ryikoranabuhanga, riza rifite uruhare runini rwibibazo nibitagenda neza.Ikibazo gikomeye mubikorwa byoroshye byumuzunguruko ni imirasire yumuriro wa electromagnetic hamwe no guhagarika amashanyarazi (EMI), cyane cyane mumashanyarazi menshi kandi yihuta. Muri iyi nyandiko ya blog, tuzasesengura inzira zifatika zo gukemura ibyo bibazo no kwemeza imikorere myiza yimikorere ya flex.

Mbere yo gucukumbura ibisubizo, reka tubanze twumve ikibazo kiriho. Imirasire ya electromagnetique ibaho mugihe amashanyarazi na magnetiki bifitanye isano no gutembera kwamashanyarazi bigenda bihindagurika kandi bigakwirakwizwa mumwanya. Ku rundi ruhande, EMI, yerekeza ku kwivanga kutifuzwa guterwa n'imirasire y'amashanyarazi. Mugihe cyinshi-cyihuta kandi cyihuta, porogaramu, imirasire hamwe no kwivanga birashobora kugira ingaruka zikomeye kumikorere yumuzunguruko wa flex, bigatera ibibazo byimikorere, ibimenyetso byerekana, ndetse na sisitemu ikananirwa.

Noneho, reka dushakishe ibisubizo bifatika kugirango dukemure ibyo bibazo mubikorwa byoroshye byuzunguruka:

1. Gukingira ikoranabuhanga:

Inzira ifatika yo guhagarika imirasire ya electromagnetic na EMI nugukoresha tekinoroji ikingira mugushushanya no gukora imiyoboro yoroheje. Kwikingira bikubiyemo gukoresha ibikoresho byayobora, nkumuringa cyangwa aluminium, kugirango habeho inzitizi yumubiri ibuza imashanyarazi ya electronique guhunga cyangwa kwinjira mukuzunguruka. Gukingira neza neza bifasha kugenzura ibyuka bihumanya no gukumira EMI udashaka.

2. Gutsindagira no gukuramo:

Uburyo bukwiye bwo guhanagura no gukuramo ni ngombwa kugirango hagabanuke ingaruka ziterwa nimirasire ya electronique. Indege yubutaka cyangwa ingufu zirashobora gukora nkingabo kandi bigatanga inzira-y-impedance yinzira igezweho, bityo bikagabanya ubushobozi bwa EMI. Byongeye kandi, gukuramo ubushobozi birashobora gushirwa mubikorwa hafi yumuvuduko wihuse kugirango uhagarike urusaku rwinshi kandi bigabanye ingaruka zumuzunguruko.

3. Imiterere n'ibigize:

Gushyira hamwe nibigize bigomba gusuzumwa neza mugihe cyo gukora flex circuit. Ibice byihuta bigomba gutandukanywa kandi ibimenyetso byerekana ibimenyetso bigomba kubikwa kure y’urusaku. Kugabanya uburebure n'ahantu hagaragara ibimenyetso byerekana ibimenyetso birashobora kugabanya cyane amahirwe yo gukwirakwiza imirasire ya electronique hamwe nibibazo bya EMI.

4. Intego yibiyungurura:

Kwinjizamo ibice byo kuyungurura nkibisanzwe muburyo bwa chokes, EMI muyunguruzi, hamwe namasaro ya ferrite bifasha guhagarika imirasire ya electromagnetic no kuyungurura urusaku udashaka. Ibi bice bihagarika ibimenyetso bidakenewe kandi bitanga inzitizi yurusaku rwinshi, bikarinda kugira ingaruka kumuzunguruko.

5. Umuhuza ninsinga bifite ishingiro neza:

Umuyoboro hamwe ninsinga zikoreshwa muguhindura imashanyarazi byoroshye ni isoko yumuriro wa electronique na EMI. Kugenzura niba ibyo bice bifite ishingiro kandi bikingiwe birashobora kugabanya ibibazo nkibi. Ubwitonzi bwateguwe neza bwikingira hamwe nubuziranenge bufite ireme hamwe nubutaka buhagije burashobora kugabanya neza imirasire ya electromagnetic nibibazo bya EMI.

Muri make

Gukemura imirasire ya electromagnetique hamwe nibibazo byo guhagarika EMI mubikorwa byoroshye byumuzunguruko, cyane cyane mubikorwa byihuta kandi byihuse, bisaba inzira ihamye kandi yuzuye. Ihuriro ryubuhanga bwo gukingira, guhuza neza no gukuramo, gutunganya neza no gushyira ibice, gukoresha ibice byo kuyungurura, no kwemeza neza guhuza imiyoboro ninsinga nintambwe zingenzi mugukemura ibyo bibazo. Mugushira mubikorwa ibyo bisubizo, injeniyeri nabashushanya barashobora kwemeza imikorere myiza, kwizerwa hamwe nimikorere yumuzunguruko woroshye mugusaba porogaramu.
