1. Kodi mungathane ndi mikangano ina mwanjira yeniyeni?
Kwenikweni, nkoyenera kugawanitsa ndikusiyanitsa analog / digito. Tiyenera kudziwa kuti kapepala kaimayi sikuyenera kuwoloka Moat momwe tingathere, ndipo njira yaposachedwa ya mphamvu ndi chizindikiro siziyenera kukhala zazikulu.
Wosstator oscillator ndi njira yabwino kwambiri yooscialation. Kuti mukhale ndi chizindikiro chokhazikika, liyenera kukumana ndi zopeza ndi gawo la gawo. Kuzindikira kwa oscillation kwa chizindikiro cha Analog kumasokonezeka mosavuta. Ngakhale ngati katundu wa alonda atawonjezeredwa, kusayanja kusokonekera sikungakhale kosiyana kwathunthu. Kuphatikiza apo, phokoso la ndege la nthaka lidzakhudzanso malo osokoneza bongo ngati ali kutali kwambiri. Chifukwa chake, mtunda pakati pa makhiristal oscator ndipo chip chimakhala choyandikira.
Inde, pali mikangano yambiri pakati pa zofuna zazothamanga kwambiri ndi emu. Koma mfundo yoyamba ndi yoti kukana ndi capertem kapena Ferngete Bead sikungapangitse mawonekedwe amagetsi a chizindikirocho kulephera kukwaniritsa zomwe mwapeza. Chifukwa chake, ndibwino kugwiritsa ntchito maluso a njira zotsatsa ndi pcb stating kuti muthetse mavuto a EMI, monga zigawenga zapamwamba kwambiri kupita kumkati. Pomaliza, kukana cacactor kapena Ferngete kugwiritsidwa ntchito kuchepetsa kuwonongeka kwa chizindikiro.

2. Kodi mungathetse bwanji kutsutsana pakati pa mawu owonera ndi ma ering othamanga kwambiri?
Makina ambiri omwe amangokhala olimba a poirping amphamvu akhazikitsa zopinga zowongolera njira yopezera mphepo ndi kuchuluka kwa mitundu. Mphamvu zolimbitsa thupi ndi zopinga za mabungwe osiyanasiyana Eda nthawi zina zimasiyana kwambiri.
Mwachitsanzo, ngakhale pali zovuta zokwanira kuti muwongolere njira ya njoka imawombera, ndi zina.
Kuphatikiza apo, kuvuta kwa kusintha kwakumaso kumathandizanso mogwirizana ndi kuthekera kwa injini yakuwala. Mwachitsanzo, kuthekera kwa kayendedwe ka kudzera pa kudzera pa kudzera pa kudzera pa kudzera pa kudzera pa vsia zokutira zamkuwa, etc.

3. Pafupifupi coupon.
Coupon yoyeserera imagwiritsidwa ntchito kuti mudziwe ngati mawonekedwe omwe akuphatikizidwa a PCB amakumana ndi zofuna za TDR (nthawi yamatanda). Nthawi zambiri, kuwunika kuti azilamulidwa kumakhala ndi milandu iwiri: waya umodzi ndi osiyana awiri.
Chifukwa chake, mzerewu mulifupi ndi mzere umodzi pa coupon yoyesa (ikakhala yosiyana ndi ina) iyenera kukhala yosiyana ndi mzere woyenera kulamuliridwa. Chofunikira kwambiri ndi malo okhalamo nthawi yochepa.
Pofuna kuchepetsa mtengo wotsogola, malo opangira TDR nthawi zambiri amakhala pafupi kwambiri ndi Probe. Chifukwa chake, mtunda ndi njira yomwe ili pakati pa mawonekedwe a siginecha ndi pansi pa coupon yoyeserera iyenera kufanana ndi zomwe zidagwiritsidwa ntchito.

4. Mu kapangidwe ka PCB yayitali, malo opanda kanthu a chizindikiro cha siginecha akhoza kuphatikizidwa ndi mkuwa, ndipo kodi zigawo za mkuwa uyenera kugawidwa pansi ndi magetsi?
Nthawi zambiri, mkuwa wopanga m'deralo umakhazikika. Ingoganizirani mtunda pakati pa mkuwa ndi mzere wa siginecha mukamagwiritsa ntchito mtengo wamkuwa pafupi ndi chingwe chothamanga kwambiri, chifukwa mkuwa womwe umagwiritsidwa ntchito umachepetsa kuwunika kwa kafukufuku. Komanso samalani kuti musakhudze mawonekedwe a zigawo zina, mwachitsanzo pamapangidwe a mzere wa Strip.

5. Kodi siginecha pakati pa magetsi ndi ndege yapansi imawerengedwa pogwiritsa ntchito mtundu wa stripline?
Inde, ndege yamphamvu ndi ndege yapansi ziyenera kuonedwa ngati mafotokozedwe apakati powerengera mawonekedwe. Mwachitsanzo, bolodi-wosanjikiza anayi: Malo apamwamba osanjikiza-magetsi okwera-pansi. Pakadali pano, mtundu wowoneka bwino wa osanjikiza wapamwamba ndi mtundu wa microstrip pamzere wokhala ndi ndege ngati ndege.

6. Kodi kuyesa kumangopangidwa zokha ndi mapulogalamu pa matabwa osindikizidwa kwambiri kuti akwaniritse zofunikira zoyeserera?
Nthawi zambiri, kaya pulogalamuyi imangokhala ndi mfundo zoyeserera kuti mukwaniritse zofunika mayeso kuti mukwaniritse ndalamazo zimadalira kuti zowonjezera zisayesedwe zimakwaniritsa zofuna za zida zoyeserera. Kuphatikiza apo, ngati chowonda ndi chandiweyani ndi malamulo owonjezera owonjezera mayeso ndi okhwima, palibe njira yowonjezera mayeso a mayeso onse. Inde, muyenera kudzaza pamanja m'malo oyesedwa.

7. Kodi kuwonjezera mfundo zoyeserera kumakhudza mtundu wa zikwangwani zothamanga kwambiri?
Kaya zingakhudze mtundu wa chizindikiro zimatengera njira yowonjezera mfundo zoyeserera ndi chizindikiro chake. Kwenikweni, zowonjezera zowonjezera (sizigwiritsa ntchito piani zomwe zilipo kapena zinsinsi ngati mfundo zoyeserera) zitha kuwonjezeredwa pamzere kapena kutulutsa mzere wamfupi kuchokera pamzerewu.
Zakale ndizofanana ndikuwonjezera kaluko yaying'ono pamzere, pomwe omaliza ndi nthambi yowonjezera. Zonsezi zimakhudza chizindikiro chothamanga kwambiri kapena zochepa, ndipo kuchuluka kwa zotsatirazi zikugwirizana ndi liwiro lazizindikiro ndi kuchuluka kwa chizindikiro. Ukulu wa ukulu ungadziwike kudzera m'lingaliro. Mfundo yovutayi, yocheperako, ndiye kuti ndibwino (Inde, ziyenera kukwaniritsa zofunikira za chida choyeserera) The akufupika nthambi, yabwinoko.
