Isahluko 12 Ukucatshangwa Kokuklama

I-Noise Suppression Design
Namathela kuzinqubo zobunjiniyela zokunciphisa umsindo lapho uklama ibhodi lesekethe eliphrintiwe (PCB). Ukucindezelwa komsindo kubalulekile ekusebenzeni kahle nasekusebenzeni kwemodemu nezinto ezizungezile.

Noma yimuphi umklamo webhodi le-OEM kufanele ucabangele kokubili umsindo okhiqizwa ebhodini nangaphandle kwebhodi ongathinta ukucubungula isignali yedijithali. Kokubili umsindo okhiqizwa ebhodini nangaphandle kwebhodi ohlanganiswe ebhodini ungathinta amaleveli esignali yesixhumi esibonakalayo kanye nekhwalithi. Umsindo kububanzi befrikhwensi othinta ukusebenza kwemodemu ubaluleke kakhulu.

Umsindo okhiqizwe ebhodini we-electromagnetic interference (EMI) ongasakazwa noma wenziwa ngaphandle kwebhodi ubaluleke ngokufanayo. Lolu hlobo lomsindo lungathinta ukusebenza kwemishini ezungezile. Iningi lama-ejensi kahulumeni wasekhaya anezidingo zesitifiketi okufanele zihlangatshezwe ukuze zisetshenziswe ezindaweni ezithile.

Isakhiwo esifanele sebhodi le-PC (ukubekwa kwengxenye, umzila wesignali, ukujiya kokulandelela kanye nejiyomethri, njalo njalo) ukukhetha kwengxenye (ukwakheka, inani, nokubekezelelana), uxhumano lwesikhombimsebenzisi, nokuvikela kuyadingeka ukuze idizayini yebhodi ifinyelele ukusebenza kwemodemu oyifunayo futhi ifinyelele. Isitifiketi se-EMI.

Ezinye izici zezinqubo ezifanele zobunjiniyela bokunciphisa umsindo zingaphezu kobubanzi balo mhlahlandlela. Bhekana namasu okunciphisa umsindo achazwe ezincwadini zobuchwepheshe kanye namajenali, izincwadi zemibhalo yobunjiniyela be-elekthronikhi nakagesi, kanye namanothi esicelo somphakeli wengxenye.

Umhlahlandlela Wesakhiwo Sebhodi Le-PC

Ngomklamo wezendlalelo ezi-4, hlinzeka ngendiza ephansi eyanele emboza ibhodi lonke. Kumiklamo yezendlalelo ezi-4, amandla nomhlabathi kuvamise ukuba sezendlalelo ezingaphakathi. Qinisekisa ukuthi wonke amandla kanye nokulandela umhlaba kungu-0.05 amayintshi ububanzi. Usayizi wembobo onconywayo wamaphini wedivayisi ungu-0.036 in. +/-0.003 in. ububanzi. Sebenzisa ama-spacers ukuze ubambe idivayisi imile endaweni yayo phakathi nenqubo ye-wave solder.

Ukuphazanyiswa kwe-Electromagnetic

Imihlahlandlela elandelayo inikezwa ngokukhethekile ukusiza ukunciphisa ukukhiqizwa kwe-EMI. Eminye yale mihlahlandlela iyafana, noma iyafana, neziqondiso ezijwayelekile. Ukuze unciphise umnikelo wedizayini esekelwe kudivayisi ku-EMI, kufanele uqonde imithombo emikhulu ye-EMI nokuthi ungayinciphisa kanjani ibe amazinga amukelekayo.

• Gcina imikhondo ephethe amasignali emvamisa ephezulu imfushane ngangokunokwenzeka.
• Nikeza indiza yaphansi noma igridi enhle. Kwezinye izimo, ibhodi lezendlalelo eziningi lingadingeka elinezendlalelo ezigcwele zokusabalalisa komhlabathi namandla.
• Amandla e-Decouple asuka phansi anama-decoupling capacitor aseduze nezikhonkwane zamandla zedivayisi ngangokunokwenzeka.
• Susa amaluphu aphansi, okuyizindlela zamanje zokubuyisela ezingalindelekile emthonjeni wamandla naphansi.
• Hlukanisa izintambo zolayini bocingo kumajekhi olayini bocingo. Ngokuvamile, sebenzisa inhlanganisela yama-inductors ochungechunge, ukuklinywa kwemodi evamile, nama-shunt capacitor.
• Izindlela zokunqamula izintambo zocingo zifana nokuhlukanisa izintambo zikagesi; Nokho, ukunqanyulwa kolayini bocingo kungase kube nzima kakhulu futhi kudinga ukunakwa okwengeziwe.
• Usizo lwedizayini oluvame ukusetshenziswa ukubeka izinyathelo zalezi zingxenye futhi zigcwaliswe njengoba kudingeka ngesikhathi sokuhlolwa kokusebenza/i-EMI kanye nesitifiketi.
• Hlukanisa intambo yamandla kusixhumi esibonakalayo sentambo yamandla ngama-decoupling capacitor. Izindlela zokunqamula izintambo zikagesi zifana nokuhlukanisa izintambo zocingo.
• Thola ama-high-frequency circuits endaweni ehlukile ukuze unciphise ukuhlanganisa amandla kwamanye amasekhethi.
• Thola izintambo nezixhumi ukuze ugweme ukuhlangana kumasekhethi anemvamisa ephezulu.
• Beka imikhondo yesiginali ephezulu kakhulu eduze kwegridi yaphansi.
• Uma usebenzisa idizayini yebhodi lezendlalelo eziningi, ungasikeki phansi noma ezindizeni zamandla futhi uqiniseke ukuthi indiza ephansi ivala yonke imikhondo.
• Nciphisa inani lokuxhunywa kwe- through-hole kumathrekhi aphethe amasignali amaza aphezulu.
• Gwema ukujika kwe-engeli yesokudla ekulandeleleni imvamisa ephezulu. Amakhona angama-degree angamashumi amane nanhlanu mahle; kodwa-ke, ukuphenduka kwerediyasi kungcono.
• Emabhodini anezingqimba ezi-2 angenayo igridi yaphansi, hlinzeka ngomkhondo wasemhlabeni wesithunzi ngakolunye uhlangothi lwebhodi ukuze uthole imikhondo ephethe amasignali amaza aphezulu.
• Lokhu kuzosebenza kahle njengembuyiselo yaphansi ye-high-frequency uma iphinda kathathu ububanzi bokulandelela isignali.
• Sabalalisa amasiginali emvamisa ephezulu ngokuqhubekayo ngomkhondo owodwa kunemikhondo eminingana ephuma endaweni eyodwa.

Electrostatic Discharge Control

Phatha wonke amadivaysi e-elekthronikhi ngezinyathelo zokuphepha ukuze ugweme ukulimala ngenxa yokunqwabelana kweshaja emile. Bona i-ANSI/ESD Association Standard (ANSI/ESD S20.20-1999) – idokhumenti “Yokuthuthukiswa Kwesilawuli Sokukhipha I-Electrostatic Ukuvikela Izingxenye Zikagesi Nezi-Electronic, Imihlangano Nezisetshenziswa.” Lo mbhalo uhlanganisa Izidingo Zokuphatha Zohlelo Lokulawulwa Kwe-ESD, Ukuqeqeshwa Kwe-ESD, Izidingo Zobuchwepheshe Zohlelo Lokulawula I-ESD (izinhlelo zokubeka phansi/ zokubopha, ukubeka phansi abasebenzi, izindawo ezivikelwe, ukupakishwa, ukumaka, okokusebenza, nokuphatha), kanye Nokuhlola Ukuzwela.

I-MultiTech ilwela ukulandela lezi zincomo. Isekhethi yokuvikela okokufaka ihlanganiswa kumadivayisi e-MultiTech ukuze kuncishiswe umthelela wokwakheka okumile. Thatha izinyathelo zokuphepha ukuze ugweme ukuchayeka ekukhishweni kwe-electrostatic ngesikhathi sokuphatha. I-MultiTech isebenzisa futhi incoma ukuthi abanye basebenzise amabhokisi aphikisana ne-static akha ikheji ye-Faraday (iphakheji eklanyelwe ukukhipha izinkambu ze-electromagnetic). I-MultiTech incoma ukuthi usebenzise ukupakisha kwethu lapho ubuyisela umkhiqizo nalapho uthumela imikhiqizo yakho kumakhasimende akho.
