Ukuyilwa kwe-PCB, ubume budlala ngendima enkulu nangakumbi ekugqibeleni kuyilo kunye nesicelo semveliso. Inyathelo ngalinye loyilo lifuna ukhathalelo olungezelekayo kunye nokuqwalaselwa ukufezekisa intsebenzo elungileyo.
I-Angle-Angle ye-Angle ikwimeko efuna ukunqandwa kangangoko inokwenzeka kwi-PCB wiring, kwaye iphantse yaba ngomnye wemigangatho yokulinganisa umgangatho we-wiring. Ke igalelo elingakanani i-angle ye-angle i-angles idluliselwe kwisayizi?
Okwesibini, amaxabiso ahlukile ngenxa yeenkqubo ezahlukeneyo zemveliso.
Inkqubo eyahlukileyo yemveliso ikhokelela kwiindleko ezahlukeneyo. Enje ngeBhodi ePhakathisiweyo yeGolide kunye neBhodi ye-tin, imilo yokutsala kunye nokuhluthwa, ukusetyenziswa kwe-screen ye-screen kunye nemigca yefilimu yefilimu kuya kwenza iindleko ezahlukeneyo, okukhokelela kwixabiso lokwahluka.
Kwimigaqo, umkhondo we-angle ekunene uza kutshintsha ububanzi bomgca womgca wokuhambisa, okukhokelela kwi-discricununuentinunue. Ngapha koko, hayi kuphela umkhondo we-angle, kodwa kunye nemikhondo ebukhali isenokubangela utshintsho olwenzileyo.
Impembelelo ye-Angle ye-Angle ye-Angle iboniswa ikakhulu kwimiba emithathu: okokuqala, ikona inokulingana nomthwalo wokunikezelwa, ukunciphisa ixesha lokunyuka; Okwesibini, ukunqunyulwa kwengcinezelo kuya kubangela ukubonakaliswa komqondiso;
Okwesithathu yi-EMI eyenziwe yingcebiso ye-angle elungileyo. I-cacititic yegesi ebangelwa kukulunga komgca wokuhambisa onokuthi ubalwe le fomula yesiqhelo: c = 61w (i-6/2 / Z0 kwikona elinganayo yekona (i-CP),
I-WI ibhekisela kububanzi bomkhondo (i-intshi), i-intshi), i-intshi), ibhekisele kwi-dielectric rhoqo yendawo ephakathi, kunye ne-Z0 yimeko yokunyanzelwa komgca wokuhambisa.
Njengoko ububanzi bomgca wokuhamba kwe-Angle buyanyuka, ukumiswa kuya kuncitshiswa, ngoko ke kuya kwenzeka into ethile yomqondiso. Singabalekisa impatho efanayo emva kokuba ububanzi bomgca bunyuswe ngokwefomula yobalo lokuthintela okhethiweyo kwinombolo yodluliselo.
Emva koko ukubala umboniso ondedwa ngokwefomrical formula: ρ = (ZS-Z0) / (ZS + Z0). Ngokubanzi, utshintsho olwenziweyo olubangelwa yi-angle ye-angle iphakathi kwe-7% ne-20%, ngoko i-ofisi ephezulu yokusebenza malunga ne-0.1. I-Shenzhen Anke PCB CO., LTD
