I-Capel Hlangana Nezidingo Zesiginali Yesivinini Esikhulu kanye ne-EMC Design Yeziyingi Eziyinkimbinkimbi ze-PCB

Yethula:

Emhlabeni ovela ngokushesha wokuklanywa kwebhodi lesifunda eliphrintiwe (PCB), ukuhlangabezana nezidingo zesignali yesivinini esikhulu nokuhambisana kwe-electromagnetic (EMC) kuyinselele enkulu.Njengoba ubuchwepheshe buthuthuka kanye nemishini kagesi iba nzima kakhulu, kunesidingo esandayo samasekhethi e-PCB ayinkimbinkimbi akwazi ukuphatha amasiginali anesivinini esikhulu kuyilapho egcina ukuhambisana kozibuthe kagesi.Kule bhulogi, sizohlola amakhono osanda kufika emakethe uCapel futhi sixoxe ngokuthi angakwazi yini ukuhlangabezana ngokuphumelelayo nokusayina kwesivinini esikhulu kanye nezidingo zokuklama ze-EMC zamasekethe e-PCB ayinkimbinkimbi.

Funda mayelana nedizayini yesignali enesivinini esikhulu:

Idizayini yesignali enesivinini esikhulu idlala indima ebalulekile ekunqumeni ukusebenza kwemishini kagesi.Imigqa yokudlulisa yamagagasi aphezulu kanye namasiginali edijithali ashintsha ngokushesha adinga ubuqotho besignali obuhle kakhulu ukuze kuvinjelwe izinkinga ezihlukahlukene zesignali yobuqotho njenge-crosstalk, izibonisi, nokuhlanekezelwa kwesignali.Ukuthola ukusebenza kwesignali yesivinini esiphezulu kudinga ukucatshangelwa ngokucophelela okufana nokulawulwa kwe-trace impedance, impedance elawulwayo kanye nokuhlaziywa kobuqotho besignali.

Idizayini ye-Electromagnetic Compatibility (EMC):

I-EMC yakhelwe ukuqinisekisa ukuthi okokusebenza kwe-elekthronikhi kusebenza ndawonye endaweni ye-electromagnetic ngaphandle kokudala ukuphazamiseka noma ukuba sengozini yokuphazamiseka.Idizayini efanele ye-EMC ifaka ukwehlisa imisebe ye-electromagnetic ekhishwa yi-PCB kanye nokwandisa ukungatheleleki kwesekethe ekuphazamisekeni kwe-electromagnetic yangaphandle (EMI).Izinkinga ze-EMC zingasingathwa ngempumelelo ngokulandela amasu okunciphisa umsindo njengokubeka phansi okufanelekile, umzila wesiginali, ukuvikela, nokuhlukanisa.

Mayelana ne-Capel:

I-Capel isofthiwe entsha yokuklama ye-PCB ethi ithuthukisa ukwakheka kwesignali enesivinini esiphezulu kanye ne-EMC.Inikeza izici ezithuthukisiwe nokusebenza okuklanyelwe ukuxazulula izinselele ezihlobene namasekhethi e-PCB ayinkimbinkimbi.Ake sibhekisise ezinye zezici zayo ezibalulekile:

1. Ukuhlaziywa kwesignali enesivinini esikhulu:

I-Capel inikeza amathuluzi esimanjemanje okuhlaziya isignali yesivinini esivumela abaklami ukuthi babikezele ngokunembile futhi bahlaziye izindaba zobuqotho besignali.Nge-impedance calculator yayo, abaklami bangaqinisekisa ukufanisa okulawulwayo kwe-impedance, ukunciphisa ukubonakaliswa kwesignali nokugcina ubuqotho besignali.Ngaphezu kwalokho, i-Capel ihlinzeka ngamakhono okulingisa athuthukile okuhlonza nokunciphisa i-crosstalk, iqinisekisa ukudluliswa kwesignali okuthembekile okuthembekile.

2. Ukuhlaziywa kwe-EMC nokwenza kahle:

U-Capel ugcizelela ukubaluleka kokuhlaziywa kwe-EMC kusukela ezigabeni zokuqala zokwakheka kwe-PCB.Ihlinzeka ngamamojula okulingisa ukusiza ukuhlonza imithombo engaba khona yokuphazanyiswa kuka-electromagnetic (EMI) nokuhlola umthelela wawo kumasekhethi.Ngokusebenzisa amasu okuhlaziya e-EMC athuthukisiwe, abaklami bangakwazi ukuhlonza futhi baxazulule izinkinga ezingase zibe khona zokuhambisana kwe-electromagnetic ukuze baqinisekise ukuhambisana nezindinganiso zomkhakha.

3. Ukuhlola Umthetho Wokuklama (i-DRC) kanye Nokuqinisekiswa Kwedizayini:

I-Capel ifaka isethi ebanzi yokuhlola umthetho wokuklama ovumela abaklami ukuthi baqinisekise imiklamo yabo ye-PCB ngokumelene nesiginali yesivinini esiphezulu kanye nezidingo zokuklama ze-EMC.I-DRC iqinisekisa ukuthi kuhlangatshezwana nemithetho eyinhloko yedizayini, ivimbele amaphutha edizayini angaba khona futhi iqinisekise ukusebenza okufanele.

4. Ukusebenzisana nokuhlanganiswa:

I-Capel ivumela ukusebenzisana okungenazihibe phakathi kwamalungu eqembu, okuvumela ukuxhumana kwesikhathi sangempela nokuphathwa kwephrojekthi.Ngaphezu kwalokho, inikeza ukuhlanganiswa ngamathuluzi ajwayelekile okuklama kanye nesofthiwe, okuvumela abaklami ukuthi basebenze ngaphakathi kokuhamba komsebenzi abakuthandayo ngenkathi besebenzisa amandla e-Capel.

Ekuphetheni:

Njengoba izinto zikagesi ziqhubeka nokuvela, isidingo sama-PCB athembekile angahlangabezana nokusayina kwesivinini esikhulu kanye nezidingo zokuklama kwe-EMC sesibucayi.Nakuba u-Capel, osanda kufika emakethe, ethembisa ukubhekana nalezi zinselele ngokusebenzisa izici ezithuthukisiwe nokusebenza, abaklami kufanele bahlole ngokugcwele amakhono ayo futhi bahlole ukuthi ihlangabezana kanjani nezidingo zabo zokuklama ezithile.Ngokufinyelela ibhalansi elungile phakathi kwedizayini yesignali enesivinini esikhulu nokucatshangelwa kwe-EMC, abaklami bangaqinisekisa amasekhethi e-PCB aqinile futhi asebenza kahle abeka ingqopha-mlando kumadivayisi kagesi azayo.
