Imultilayer

Kulesi sigaba, singathanda ukukunikeza imininingwane eyisisekelo mayelana nezinketho zesakhiwo, ukubekezelelana, izinto zokwakha, nemihlahlandlela yokuhlelwa kwamabhodi ama-multilayer. Lokhu kufanele kwenze impilo yakho ibe lula njengonjiniyela futhi kukusize ukuklama amabhodi wakho wesifunda aphrintiwe ukuze alungiselelwe ukukhiqizwa ngezindleko eziphansi kakhulu.

Imininingwane ejwayelekile

Izinto ze-PCB

Njengomhlinzeki wobuchwepheshe obuhlukahlukene be-PCB, amavolumu, izinketho zesikhathi sokuhola, sinokukhethwa kwezinto ezijwayelekile lapho umkhawulo womkhawulokudonsa omkhulu wezinhlobo ezahlukahlukene ze-PCB ungambozwa futhi ohlale utholakala endlini.

Izidingo zokunye noma okokusebenza okukhethekile nazo kungahlangatshezwana nazo ezimweni eziningi, kepha, ngokuya ngezidingo eziqondile, kungadingeka izinsuku ezi-10 zokusebenza ukuze kutholwe lokho okubhaliwe.

Thintana nathi futhi uxoxe ngezidingo zakho nomunye wokuthengisa kwethu noma iqembu le-CAM.

Izinto ezijwayelekile ezigcinwe esitokweni:

Ubukhulu beCu bezingqimba zangaphakathi: Okujwayelekile - 18µm no-35 µm,

ngesicelo 70 µm, 105µm no 140µm

Uhlobo lwento: FR4

I-Tg: cishe. 150 ° C, 170 ° C, 180 ° C

εr ku-1 MHz: ≤5,4 (ejwayelekile: 4,7) Okuningi kutholakala ngokucela

Beka isitaki phezulu

Ukuqoqwa kwe-PCB kuyinto ebalulekile ekutholeni ukusebenza kwe-EMC komkhiqizo. Ukuqoqwa okuhle kungasebenza kakhulu ekwehliseni imisebe evela kuluphu ku-PCB, kanye nezintambo ezixhunywe ebhodini.

Izici ezine zibalulekile maqondana nokucatshangelwa kokuqoqwa kwamabhodi:

1. Inani lezendlalelo,

2. Inombolo nezinhlobo zezindiza (amandla kanye / noma umhlaba) ezisetshenzisiwe,

3. Ukuhleleka noma ukulandelana kwezendlalelo, futhi

4. Isikhala phakathi kwezendlalelo.

Imvamisa akubhekwa kangako ngaphandle kwenani lezendlalelo. Ezimweni eziningi ezinye izici ezintathu zibaluleke ngokulinganayo. Lapho unquma ngenani lezendlalelo, okulandelayo kufanele kubhekwe:

1. Inani lezimpawu ezizohanjiswa nezindleko,

2. Imvamisa

3. Ngabe umkhiqizo kuzofanele uhlangabezane nezidingo zokuphuma zeClass A noma ze-Class B?

Imvamisa kubhekwa kuphela into yokuqala. Empeleni zonke izinto zibaluleke kakhulu futhi kufanele zibhekwe ngokulinganayo. Uma idizayini enkulu izotholakala ngesilinganiso esiphansi sesikhathi nangezindleko eziphansi kakhulu, into yokugcina ingabaluleka kakhulu futhi akufanele inganakwa.

Isigaba esingenhla akufanele sithathwe njengesisho ukuthi awukwazi ukwenza ukwakheka okuhle kwe-EMC ebhodini lezingqimba ezine noma eziyisithupha, ngoba uyakwazi. Kukhombisa kuphela ukuthi zonke izinhloso azinakufezwa ngasikhathi sinye futhi ukuhlehla okuthile kuzodingeka. Njengoba zonke izinhloso ezifunwayo ze-EMC zingahlangatshezwa ngebhodi elinezingqimba eziyisishiyagalombili, asikho isizathu sokusebenzisa izingqimba ezingaphezu kweziyisishiyagalombili ngaphandle kokufaka izingqimba zomzila wesiginali ezingeziwe.

Ukujiya okujwayelekile kokuhlanganiswa kwama-PCB amaningi kungu-1.55mm. Nazi ezinye izibonelo ze-multilayer PCB stack up.
