Sombulula imiba ye-EMI kulwakhiwo lwePCB oluguquguqukayo losetyenziso olukwi-frequency ephezulu kunye nesantya esiphezulu.

I-Flexible circuit fabrication isetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeenzuzo zayo ezininzi ezifana nokuguquguquka, ukukhanya, ukudibanisa kunye nokuthembeka okuphezulu. Nangona kunjalo, njengayo nayiphi na enye inkqubela phambili yetekhnoloji, iza nesabelo sayo esifanelekileyo semiceli mngeni kunye nezithintelo.Umceli mngeni omkhulu kwimveliso yesekethe eguquguqukayo yimitha ye-electromagnetic interference kunye ne-electromagnetic interference (EMI), ngakumbi kwi-high-frequency kunye ne-high-speed applications. Kule posi yebhlog, siza kuphonononga iindlela ezisebenzayo zokujongana nale miba kwaye siqinisekise ukusebenza ngokufanelekileyo kweesekethe eziguqukayo.

Phambi kokuba singene nzulu kwizisombululo, masiqale siqonde ingxaki ekhoyo. Imitha ye-electromagnetic yenzeka xa umhlaba wombane kunye nemagnethi ezinxulumene nokuhamba kombane wangoku ujikeleza kwaye usasazeke esithubeni. I-EMI, kwelinye icala, ibhekisa kuphazamiseko olunganqwenelekiyo olubangelwa zezi mitha ye-electromagnetic radiation. Kwi-high-frequency kunye ne-high-speed applications, i-radiation enjalo kunye nokuphazamiseka kunokuchaphazela kakhulu ukusebenza kwesekethe ye-flex, kubangela imiba yokusebenza, ukunciphisa umqondiso, kunye nokungaphumeleli kwenkqubo.

Ngoku, makhe sijonge izisombululo ezisebenzayo zokujongana nale miba kwimveliso yesekethe eguquguqukayo:

1. Itekhnoloji yokukhusela:

Indlela esebenzayo yokucinezela imitha ye-electromagnetic radiation kunye ne-EMI kukusebenzisa itekhnoloji yokukhusela kuyilo kunye nokwenziwa kweesekethe eziguquguqukayo. Ukukhusela kubandakanya ukusebenzisa izinto zokuqhuba, ezifana nobhedu okanye i-aluminium, ukudala umqobo womzimba othintela amasimi ombane ukuba abaleke okanye angene kwisekethe. Ukhuselo oluyilwe ngokufanelekileyo lunceda ukulawula ukukhutshwa kweesekethe kunye nokuthintela i-EMI engafunwayo.

2. Ukumhlaba kunye nokuqhawula:

Iindlela ezifanelekileyo zokubeka umhlaba kunye nokudibanisa zibalulekile ekunciphiseni iziphumo zemitha ye-electromagnetic. Umhlaba okanye indiza yamandla inokusebenza njengekhaka kwaye ibonelele ngendlela ephantsi yokuthintela ukuhamba kwangoku, ngaloo ndlela inciphisa amandla e-EMI. Ukongeza, i-decoupling capacitors inokubekwa ngobuchule kufutshane namacandelo anesantya esiphezulu ukucinezela ingxolo ephezulu-frequency kunye nokunciphisa impembelelo yayo kwisekethe.

3. Uyilo kunye nokubekwa kwecandelo:

Uyilo kunye nokubekwa kwecandelo kufuneka kuqwalaselwe ngononophelo ngexesha lokwenziwa kwesekethe ye-flex. Amalungu anesantya esiphezulu kufuneka abekwe zodwa omnye komnye kwaye imikhondo yemiqondiso kufuneka igcinwe kude nemithombo yengxolo enokubakho. Ukunciphisa ubude kunye nendawo ye-loop yomzila wesignali kunokunciphisa kakhulu ukubakho kwemitha ye-electromagnetic kunye neengxaki ze-EMI.

4. Injongo yesihluzo sesiqalelo:

Ukubandakanya izinto zokucoca ezinje ngemowudi eqhelekileyo yokukrwitshwa, izihluzi ze-EMI, kunye namaso e-ferrite kunceda ukucinezela imitha ye-electromagnetic kunye nokucoca ingxolo engafunekiyo. Ezi zixhobo zivimba izibonakaliso ezingafunekiyo kwaye zibonelela nge-impedance kwi-high-frequency ingxolo, ukuthintela ukuchaphazela isiphaluka.

5. Iziqhagamshelo kunye neentambo zimiswe ngokufanelekileyo:

Iziqhagamshelo kunye neentambo ezisetyenziswa kwimveliso yeesekethe eziguquguqukayo ziyimithombo enokubakho yemitha ye-electromagnetic radiation kunye ne-EMI. Ukuqinisekisa ukuba la macandelo asekelwe ngokufanelekileyo kwaye akhuselwe kunokunciphisa iingxaki ezinjalo. Izikhuselo zekhebula eziyilwe ngobunono kunye neziqhagamshelo ezikumgangatho ophezulu ezinesiseko esifanelekileyo zinokunciphisa ngokufanelekileyo imitha ye-electromagnetic kunye neengxaki ze-EMI.

Isishwankathelo

Ukusombulula imitha yemitha ye-electromagnetic kunye neengxaki zokucinezelwa kwe-EMI kwimveliso yesekethe eguquguqukayo, ngakumbi kwi-high-frequency kunye ne-high-speed application, kufuna indlela ecwangcisiweyo nepheleleyo. Ukudityaniswa kweendlela zokukhusela, ukusekwa okufanelekileyo kunye nokuqhawula, ukucwangciswa ngononophelo kunye nokubekwa kwecandelo, ukusetyenziswa kwamacandelo okucoca, kunye nokuqinisekisa ukumiselwa ngokufanelekileyo kweziqhagamshelo kunye neentambo ngamanyathelo abalulekileyo ekunciphiseni le mingeni. Ngokuphumeza ezi zisombululo, iinjineli kunye nabaqulunqi banokuqinisekisa ukusebenza kakuhle, ukuthembeka kunye nokusebenza kweesekethe eziguquguqukayo kwizicelo ezifunwayo.
