Intshayelelo

Ingqibelelo yomqondiso idlala indima ebalulekileyo ekusebenzeni nasekuthembekeni kwezixhobo zombane zanamhlanje. Ukuyila iibhodi zeesekethe eziqinileyo ezidibanisa ukuguquguquka kweesekethe eziguquguqukayo kunye namandla okwakhiwa kweebhodi eziqinileyo zibonakalisa imingeni ekhethekileyo ekufuneka iqwalaselwe ukuze kuqinisekiswe imfezeko yophawu olufanelekileyo.Kule post yebhlog, siza kuphonononga iingqwalasela eziphambili kunye neendlela zenyathelo nenyathelo lokuyila iibhodi zesekethe eziqinileyo ezigcina ingqibelelo yomqondiso ngamaxesha onke.Ngokulandela ezi zikhokelo, iinjineli kunye nabaqulunqi banokucombulula ngokufanelekileyo imiba yengqibelelo yomqondiso kunye nokuvelisa iibhodi zeesekethe ezikumgangatho ophezulu.

1. Qonda imingeni yengqibelelo yomqondiso kuyilo lwebhodi yesekethe engqongqo

Ukuqinisekisa intembeko yomqondiso webhodi yesekethe engqongqo, kubalulekile ukuqonda kuqala imingeni enokuthi ichaphazele ukusebenza kwayo. Eminye imiba ebalulekileyo ibandakanya ulawulo lwe-impedance, ukubekwa kwesinxibelelanisi, ulawulo lwe-thermal, kunye noxinzelelo lomatshini ngenxa yokugoba kunye nokuguquguquka.

I-1.1 Ukulawulwa kwe-impedance: Ukugcina i-impedance engaguqukiyo kwiimpawu zesignali kubalulekile ekukhuseleni ukubonakaliswa kweempawu kunye nokulahlekelwa.Ukupakishwa okufanelekileyo kwe-dielectric, ukulandelwa kwe-impedance elawulwayo, kunye nobuchule obuchanekileyo bokuphelisa yingqwalasela ebalulekileyo.

1.2. Ukubekwa kwe-Connector: Ukubekwa kobuchule bokudibanisa kubalulekile ekunciphiseni ukunciphisa umqondiso kunye nokuqinisekisa ukuxhamla okuthembekileyo.Khetha indawo ngononophelo ukunciphisa amandla eparasitic, unciphise ukungaqhubeki, kwaye unqande ukungqubana.

1.3. Ulawulo lwe-Thermal: Imiceli mngeni yobushushu efana nokufudumeza kwendawo kunye nokuchithwa kobushushu okungalinganiyo kunokuchaphazela kakubi imfezeko yomqondiso.Ubuchule bolawulo lwe-thermal olufanelekileyo, kubandakanywa ukuchithwa kwe-thermal ngokufanelekileyo kunye nokulandela umkhondo, kubalulekile ekugcineni ukusebenza kakuhle.

1.4. Uxinzelelo lomatshini: Ukugoba kunye nokugoba kunokusebenzisa uxinzelelo lomatshini kwiibhodi zesekethe eziqinileyo. Olu xinzelelo lunokubangela ikhefu lokulandela umkhondo, utshintsho lwe-impedance, kunye nokuphazamiseka komqondiso.Ukuqwalaselwa ngokucophelela kwi-radius ye-bend, ukuqiniswa kwendawo yokugoba, kunye nokubekwa kwecandelo kunokunciphisa le miba.

2. Isikhokelo sesinyathelo-nge-nyathelo sokuqinisekisa ukuthembeka komqondiso

Ukuyila iibhodi zesekethe eziqinileyo kunye nengqibelelo yomqondiso obalaseleyo kufuna ukulandela izikhokelo ezibanzi kunye namanyathelo. Masijonge kwisikhokelo ngasinye ukuze sifumane ukuqonda okungcono.

2.1. Chaza imiqobo kunye neemfuno zoyilo: Qala ngokuchaza iimfuno zeprojekthi, kubandakanya umbane, oomatshini, kunye neenkcukacha zendibano.Ukuqonda le mida ukususela ekuqaleni kunokunceda ukukhokela inkqubo yoyilo.

2.2. Sebenzisa izixhobo zesoftware ukuhlalutya ukulinganisa: Sebenzisa i-simulators ye-electromagnetic, iiplatifomu zokuhlalutya imfezeko yomqondiso kunye nezinye izixhobo zesoftware ukulinganisa ukusebenza kwebhodi yesekethe.Hlalutya iiparitha eziphambili ezifana ne-impedance, i-crosstalk kunye nokucamngca ukuchonga imiba enokubakho kwaye wenze uhlengahlengiso oluyimfuneko.

2.3. Ukucwangcisa ukupakishwa: Ukuseka uyilo oluphuculweyo lokupakisha ukuhlanganisa ngokufanelekileyo iileya eziqinileyo neziguquguqukayo.Qinisekisa ukuba ukhetha izinto ezifanelekileyo zoluhlu ngalunye ukuhlangabezana neemfuno zokusebenza kunye nokuthembeka. Qwalasela ulawulo lwe-impedance, intembeko yomqondiso, kunye nokuzinza koomatshini ngexesha lokucwangciswa kwe-stackup.

2.4. Landela umkhondo kunye nokubekwa kwezibini ezahlukeneyo: Nika ingqwalaselo ethe kratya ekulandeleni umkhondo kunye nokubekwa kwezibini ezahlukeneyo ukunciphisa umonakalo wophawu.Gcina ububanzi bomkhondo obuhambelanayo, gcina ukwahlukana phakathi kweempawu zesantya esiphezulu kunye nezinye izinto, kwaye uphathe ukuyila kwendlela yokubuya ngononophelo.

2.5. Ukubekwa kwesiqhagamshelo kunye noyilo: Khetha ngononophelo iintlobo zekhonkco kunye nokubekwa kwazo ukunciphisa ukuncipha komqondiso.Xa uyila izihlanganisi, nciphisa ubude bendlela yomqondiso, uthintele ii-vias ezingeyomfuneko, kwaye uqwalasele imigaqo yothumelo lothumelo.

2.6. Ulawulo lwe-Thermal: Ukuphumeza izicwangciso zokulawula ukushisa okusebenzayo ukukhusela ukushisa kunye nemiba yemfezeko yesignali elandelayo.Ukusasaza ubushushu ngokulinganayo, sebenzisa iivents ezishushu, kwaye ucinge ngokusebenzisa iipateni zobushushu ukukhupha ubushushu ngokufanelekileyo.

2.7. Uncedo loxinzelelo lomatshini: Iimpawu zokuyila ezinciphisa uxinzelelo lomatshini, njenge-radii ye-bend efanelekileyo, ukuqinisa, kunye neendawo eziguquguqukayo ukuya kwezilukhuni.Qinisekisa ukuba uyilo lunokumelana nokugoba okulindelweyo kunye nokugoba ngaphandle kokuphazamisa ingqibelelo yesignali.

2.8. Dibanisa uyilo lwemigaqo yokwenziwa kwemveliso (DFM): Sebenza nePCB yokwenziwa kunye namaqabane endibano ukubandakanya imigaqo yeDFM kuyilo.Oku kuqinisekisa ukwenziwa, kunciphisa imingcipheko enokubakho yemfezeko yomqondiso, kunye nokuphucula ukusebenza kakuhle kwemveliso.

Ukuqukumbela
