Indlela yokubala iMfezeko yoMqondiso kwiRigid-Flex yoYilo lwePCB

Ingqibelelo yomqondiso yinkalo ebalulekileyo yoyilo lwePCB, ingakumbi kwiiPCB eziguquguqukayo. Ezi bhodi zeesekethe ezizodwa zibonelela ngokuguquguquka kunye nokuthembeka okufunekayo kwizixhobo ze-elektroniki eziphambili zanamhlanje. Nangona kunjalo, ngenxa yobume bayo obuntsonkothileyo, ukuqinisekisa ingqibelelo yophawu oluchanekileyo kuyilo lwePCB eguquguqukayo kunokuba ngumngeni.

Kule post yebhlog, siza kuxoxa ngezinto eziphambili ekufuneka ziqwalaselwe kunye namanyathelo abandakanyekayo xa kubalwa imfezeko yesiginali yoyilo lwePCB elukhuni.

1. Qonda iziseko zemfezeko yomqondiso

Ingqibelelo yomqondiso ibhekisa kumgangatho weempawu zombane njengoko zidlula kwiPCB. Kubandakanya ukuhlalutya kunye nokulawula izinto ezahlukeneyo ezinokuchaphazela ukusebenza komqondiso, njenge-impedance, ingxolo, i-crosstalk, kunye nokubonakalisa.

Kwii-PCB eziguquguqukayo eziqinileyo ezidibanisa ii-substrates eziqinileyo neziguquguqukayo, imfezeko yomqondiso iba yinto ebaluleke ngakumbi. Utshintsho phakathi kwamacandelo aqinileyo kunye aguquguqukayo anokwazisa utshintsho lwe-impedance, ukunciphisa umqondiso, kunye neminye imiba yengqibelelo yomqondiso.

2. Chonga iimpawu eziphambili

Inyathelo lokuqala ekubaleni isiginali imfezeko kukuchonga iimpawu ezibalulekileyo kuyilo lwePCB oluguquguqukayo. Ezi miqondiso zezona zinovakalelo kwimiba yemfezeko yomqondiso kwaye zinokubandakanya imiqondiso enesantya esiphezulu, imiqondiso yewotshi, imiqondiso yonikezelo lwamandla, okanye nawuphi na umqondiso obalulekileyo ekusebenzeni ngokufanelekileyo kwesixhobo.

Ngokugxininisa kwiimpawu ezibalulekileyo, unokubeka phambili uhlalutyo kunye nokunciphisa imiba yemfezeko yomqondiso.

3. Hlalutya ulawulo lwe-impedance

Ulawulo lwe-impedance lubalulekile ekugcineni ukunyaniseka komqondiso. Iqinisekisa ukuba i-impedance ye-signal trace ihambelana ne-impedance yeempawu zomzila wothumelo osetyenzisiweyo. Kwii-PCB eziguquguqukayo eziqinileyo, utshintsho lwe-impedance lungenzeka kwindawo yokutshintsha phakathi kweendawo eziqinileyo kunye neziguquguqukayo.

Ukubala i-impedance kunye nokuqinisekisa ulawulo lwayo, ungasebenzisa i-impedance calculator, isixhobo sokulinganisa, okanye ukhangele i-data sheet enikezwe ngumvelisi we-PCB. Ngokubala ngokuchanekileyo kunye nokulawula i-impedance, ukubonakaliswa komqondiso kunokuncitshiswa, ukuqinisekisa ukuhanjiswa kwesignali engcono.

4. Linganisa kwaye uhlalutye imfezeko yomqondiso

Ukulinganisa sisixhobo esinamandla sokuhlalutya imfezeko yomqondiso kuyilo lwePCB. Ngokusebenzisa isoftware ekhethekileyo, ungalinganisa indlela yokuziphatha kwemiqondiso kwaye uchonge imiba enokubakho yemfezeko yesiginali phambi kokwenziwa.

Ukulinganisa kunokukunceda uvavanye iiparamitha ezinje ngedayagram yamehlo, isantya sempazamo encinci, kunye nomda wengqibelelo yomqondiso. Ikuvumela ukuba uvavanye iimeko ezahlukeneyo, wandise umkhondo, kwaye uqinisekise ukhetho lwakho loyilo.

5. Nciphisa i-crosstalk

I-Crosstalk yenzeka xa imiqondiso iphazamisana enye kwenye ngenxa yokudityaniswa kwe-electromagnetic phakathi kwee-conductor ezikufutshane. Kwii-PCB eziguquguqukayo eziqinileyo, ukulawula i-crosstalk kulucelomngeni ngakumbi ngenxa yokusondela kwabaqhubi kwindawo ye-flex.

Ukunciphisa i-crosstalk, unokusebenzisa ubuchule obunjengokwandisa isithuba phakathi kweetrayisi, ukusebenzisa umhlaba okanye iinqwelomoya zamandla njengamakhaka, ukongeza izinto zokwahlula, okanye ukuphumeza umzila wokulandelela olawulwa yi-impedance.

6. Qwalasela imiqondiso eyahlukileyo

Ukubonakaliswa okungafaniyo yiteknoloji esebenzayo yokuhanjiswa kwedatha ngesantya esiphezulu. Ngokusebenzisa imiqondiso emibini eyongezelelweyo yobukhulu obulinganayo kodwa i-polarity echaseneyo, ibonelela ngokhuseleko lwengxolo kwaye inciphisa ithuba lokuthotywa komqondiso.

Kuyilo lwePCB oluguquguqukayo, ukuphumeza izibini ezahlukeneyo kunceda ukugcina imfezeko yomqondiso kunye nokunciphisa ukuphazamiseka kwe-electromagnetic. Nangona kunjalo, kufuneka kuthatyathwe ukhathalelo ukuze kuqinisekiswe i-impedance elinganayo kunye nokulawulwa kwe-offset phakathi kwezibini ezahlukeneyo.

7. Qinisekisa uyilo ngokuphindaphindiweyo

Ukuqinisekiswa koyilo yinkqubo ephindaphindwayo ebandakanya ukulinganisa ngokuphindaphindiweyo, ukuhlalutya, kunye nokuvavanya uyilo lwePCB. Inceda ukuchonga nokusombulula imiba yemfezeko yomqondiso kumanqanaba ahlukeneyo enkqubo yoyilo.

Ngokuqhuba uthotho lophononongo loyilo, ukulinganisa imfezeko yomqondiso, kunye novavanyo lweprototype, unokuqinisekisa ukuba uyilo lwakho lwePCB oluguquguqukayo luyahlangabezana neenkcukacha ezifunekayo zesiginali.

Isishwankathelo

Ukubala umqondiso wengqibelelo yoyilo lwePCB oluguquguqukayo lubandakanya ukuqonda imingeni yayo ekhethekileyo, ukuhlalutya imiqondiso ebalulekileyo, ukulawula i-impedance, ukunciphisa i-crosstalk, kunye nokuqinisekisa ngokuphindaphindiweyo uyilo. Ngokulandela la manyathelo kunye nokulinganisa izixhobo zokulinganisa kunye nobuchule bokuqinisekisa, unokuqinisekisa ngokufanelekileyo imfezeko yophawu olufanelekileyo kuyilo oluguquguqukayo lwePCB.
