4-Inzira ya PCB Igisubizo: EMC ningaruka zubusugire bwibimenyetso

Ingaruka zumurongo wibice 4 byumuzunguruko no gutandukanya ibice kuri electromagnetic ihuza hamwe nuburinganire bwibimenyetso akenshi bitera ingorane zikomeye kubashakashatsi nabashushanya. Gukemura neza ibyo bibazo nibyingenzi kugirango habeho gukora neza no gukora neza ibikoresho bya elegitoroniki.Muri iyi nyandiko ya blog, tuzaganira ku buryo bwo gukemura ikibazo cyingaruka zumurongo wa 4 wumurongo wumuzunguruko wiring hamwe nu ntera igaragara kuri electromagnetic ihuza hamwe nuburinganire bwibimenyetso.

Iyo bigeze ku ngaruka za 4-layer yumuzunguruko uyobora inzira ya electromagnetic ihuza (EMC) hamwe nuburinganire bwibimenyetso, kimwe mubibazo byingenzi ni inzira nyabagendwa.Crosstalk ni ihuriro ridakenewe ryingufu za electromagnetique hagati yimirongo yegeranye cyangwa ibice kuri PCB, bitera kugoreka ibimenyetso no gutesha agaciro. Gukwirakwiza neza hamwe no gutandukanya ibimenyetso bishobora kugabanya cyane iki kibazo.

Kugirango uhindure EMC nibimenyetso byerekana ubuziranenge, nibyingenzi gukoresha software ishushanya ishobora gukora kwigana no gusesengura neza.Ukoresheje ibikoresho bya software nka electromagnetic yumurima ukemura, abashushanya barashobora gusuzuma ubushobozi bwambukiranya ibidukikije mubidukikije mbere yo gukomeza na prototyping physique. Ubu buryo butwara igihe, bugabanya ibiciro, kandi butezimbere ubwiza bwibishushanyo.

Ikindi kintu ugomba gusuzuma ni uguhitamo ibikoresho bya PCB.Ihuriro ryibikoresho byiza bya dielectric hamwe nubunini bukwiye birashobora kugira ingaruka zikomeye kumyitwarire ya electronique ya PCB. Ibikoresho byujuje ubuziranenge bifite igihombo gito cya dielectric hamwe nubushobozi bugenzurwa bifasha kuzamura ubuziranenge bwibimenyetso no kugabanya ibyuka byangiza amashanyarazi.

Byongeye kandi, intera igaragara hagati yumurongo wa 4-wumuzunguruko irashobora kugira ingaruka cyane kuri EMC nubusugire bwibimenyetso.Byiza cyane, intera iri hagati ya PCB yegeranye igomba kuba nziza kugirango igabanye amashanyarazi kandi igabanye ibimenyetso bikwiye. Inganda zinganda nubuyobozi bugomba gukurikizwa mugihe hagenwe umwanya ukwiye wa porogaramu runaka.

Kugira ngo ibyo bibazo bikemuke, ingamba zikurikira zirashobora gukoreshwa:

1. Gushyira ibice byitondewe:Gushyira ibice bifatika bifasha kugabanya inzira nyabagendwa kuri PCB. Mugushira mubikorwa ingamba, abashushanya barashobora kugabanya uburebure bwikimenyetso cyihuta cyerekana ibimenyetso kandi bikagabanya imbaraga za electronique. Ubu buryo ni ingenzi cyane mugihe uhuye nibice bikomeye hamwe nizunguruka zoroshye.

2. Igishushanyo mbonera:Kugera kubutaka bukomeye ni tekinoroji yingenzi yo kugenzura EMC no kunoza ubuziranenge bwibimenyetso. Igice cyubutaka gikora nkingabo, kugabanya ikwirakwizwa ryumurongo wa electromagnetique no gukumira kwivanga hagati yikimenyetso gitandukanye. Ni ngombwa kwemeza tekinoroji ikwiye, harimo gukoresha vias nyinshi kugirango uhuze indege zubutaka mubice bitandukanye.

3. Igishushanyo mbonera cya stackup:Igishushanyo mbonera cyiza kirimo guhitamo urwego rukwiye rwibimenyetso, ubutaka, nimbaraga. Ubwitonzi bwateguwe neza bufasha kugera ku mbogamizi zagenzuwe, kugabanya inzira nyabagendwa, no kunoza ibimenyetso byuzuye. Ibimenyetso byihuta birashobora kunyuzwa kumurongo wimbere kugirango wirinde kwivanga hanze.

Ubuhanga bwa Capel mukuzamura EMC no kwerekana ubunyangamugayo:

Hamwe nuburambe bwimyaka 15, Capel ikomeje kunoza imikorere yinganda no gukoresha ikoranabuhanga rigezweho kugirango hongerwe EMC nibimenyetso byerekana ubunyangamugayo. Ibintu byingenzi byaranze Capel ni ibi bikurikira:
- Ubushakashatsi bwagutse:Capel ishora mubushakashatsi bunoze kugirango igaragaze inzira n'ibibazo bigaragara mugushushanya kwa PCB kugirango ukomeze imbere y'umurongo.
- Ibikoresho bigezweho:Capel ikoresha ibikoresho bigezweho kugirango ikore PCB zoroshye na PCBs zikomeye, byemeza neza kandi neza.
- Ababigize umwuga:Capel ifite itsinda ryinzobere ninzobere zifite ubuhanga bwimbitse murwego, zitanga ubushishozi ninkunga yo kuzamura EMC nibimenyetso byubuziranenge.

Muri make

Gusobanukirwa ningaruka zumurongo wa 4 wumuzunguruko wumurongo hamwe nu ntera igaragara kuri electromagnetic ihuza hamwe nuburinganire bwibimenyetso nibyingenzi mugushushanya ibikoresho bya elegitoroniki. Ukoresheje kwigana bigezweho, gukoresha ibikoresho byiza, no gushyira mubikorwa ingamba zifatika zo gushushanya, injeniyeri zirashobora gutsinda izo mbogamizi kandi ikemeza imikorere ya PCB muri rusange no kwizerwa. Hamwe nuburambe bunini no kwiyemeza kuba indashyikirwa, Capel akomeza kuba umufatanyabikorwa wizewe mugutsinda ibyo bibazo. Mugukoresha tekinike nziza muburyo bwimiterere, kubutaka no kwerekana ibimenyetso, mugihe ukoresheje ubuhanga bwa Capel, abashushanya barashobora kugabanya EMI, kuzamura ubuziranenge bwibimenyetso, no kubaka ikibaho cyizewe kandi cyiza.
