1. Nigute ushobora gukemura amakimbirane amwe n'amwe mu nsinga zifatika?
Mubisanzwe, birakwiye kugabana no gutandukanya analog / sisitemu yubutaka.Twabibutsa ko ibimenyetso byerekana ibimenyetso bitagomba kurenga umwobo uko bishoboka kwose, kandi inzira igaruka yo gutanga amashanyarazi nibimenyetso ntibigomba kuba binini cyane.
Ikirahure cya kristu nikigereranyo cyiza cyiza cyo kuzunguruka.Kugira ibimenyetso bihindagurika bihamye, bigomba kuba byunguka inyungu hamwe nicyiciro cyihariye.Ibinyeganyega byerekana iki kimenyetso kigereranya birahungabana byoroshye.Nubwo ibimenyetso byuburinzi byongeweho, intambamyi ntishobora kuba wenyine.Byongeye kandi, urusaku ruri ku butaka ruzagira ingaruka no ku cyerekezo cyiza cyo guhindagurika niba ari kure cyane.Kubwibyo, intera iri hagati ya kristu oscillator na chip igomba kuba yegeranye bishoboka.
Mubyukuri, hariho amakimbirane menshi hagati yihuta yihuta hamwe nibisabwa EMI.Ariko ihame shingiro nuko kurwanya hamwe na capacitance cyangwa isaro ya ferrite yongeweho na EMI idashobora gutuma ibintu bimwe na bimwe biranga amashanyarazi byerekana ibimenyetso binanirwa kubahiriza ibisobanuro.Kubwibyo, nibyiza gukoresha ubuhanga bwo gutondekanya ibimenyetso hamwe na PCB gutondeka kugirango ukemure cyangwa ugabanye ibibazo bya EMI, nkibimenyetso byihuta bijya murwego rwimbere.Hanyuma, ubushobozi bwo kurwanya cyangwa isaro ya ferrite bikoreshwa mukugabanya ibyangiritse kubimenyetso.

2. Nigute wakemura amakimbirane hagati yo gukoresha intoki no gukoresha ibyuma byihuta byihuta?
Byinshi mubikoresho byikora byikora bya software ikomeye yashizeho imbogamizi zo kugenzura uburyo bwo guhinduranya n'umubare wa vias.Ubushobozi bwa moteri yubushobozi hamwe nimbogamizi zo gushiraho ibintu bitandukanye bya EDA rimwe na rimwe biratandukanye cyane.
Kurugero, niba hari inzitizi zihagije zo kugenzura inzira yinzoka yinzoka, niba bishoboka kugenzura intera yimiterere yabantu batandukanye, nibindi. Ibi bizagira ingaruka niba uburyo bwo kuyobora inzira bwikora bushobora guhura nigitekerezo cyabashushanyije.
Byongeye kandi, ingorane zo guhindura intoki intoki nazo zifitanye isano rwose nubushobozi bwa moteri izunguruka.Kurugero, ubushobozi bwo gusunika inzira, ubushobozi bwo gusunika kunyura, ndetse nubushobozi bwo gusunika kurugero rwumuringa, nibindi. Guhitamo router ifite moteri ikomeye ya moteri nigisubizo.

3. Kubijyanye na coupon yikizamini.
Ikizamini cya coupon ikoreshwa mugupima niba inzitizi iranga ikibaho cyakozwe na PCB yujuje ibyangombwa bisabwa hamwe na TDR (Time Domain Reflectometer).Mubisanzwe, inzitizi igomba kugenzurwa ifite imanza ebyiri: insinga imwe hamwe na couple itandukanye.
Kubwibyo, umurongo w'ubugari n'umurongo utandukanijwe kuri test ya coupon (mugihe hari itandukaniro ritandukanye) bigomba kuba nkumurongo ugomba kugenzurwa.Ikintu cyingenzi cyane ni ahantu ho guhagarara mugihe cyo gupima.
Kugirango ugabanye agaciro ka inductance yubutaka bwubutaka, ahantu hahanamye ya TDR mubusanzwe iba yegereye cyane iperereza.Kubwibyo, intera nuburyo hagati yikimenyetso cyo gupima ibimenyetso nubutaka bwikigereranyo kuri coupon igomba guhuza iperereza ryakoreshejwe.

4. Mu gishushanyo cyihuse cya PCB, ahantu hatagaragara h’ibimenyetso hashobora gushyirwaho umuringa, kandi nigute umuringa w’umuringa w’ibice byinshi byerekana ibimenyetso wagabanywa hasi no gutanga amashanyarazi?
Mubisanzwe, isahani y'umuringa ahantu hatagaragara iba ishingiye.Gusa witondere intera iri hagati yumuringa numurongo wibimenyetso mugihe ushyizeho umuringa kuruhande rwumurongo wihuta wihuta, kuko umuringa ushyizwemo bizagabanya inzitizi yibiranga gato.Witondere kandi kutagira ingaruka kubiranga inzitizi zindi nzego, kurugero muburyo bw'imirongo ibiri.

5. Birashoboka gukoresha umurongo wa microstrip kumurongo kugirango ubare inzitizi iranga umurongo wibimenyetso kumurongo wamashanyarazi?Ikimenyetso kiri hagati yumuriro nindege yubutaka gishobora kubarwa ukoresheje moderi ya stripline?
Nibyo, indege yindege nindege yubutaka bigomba gufatwa nkindege zerekana mugihe ubara inzitizi iranga.Kurugero, ibice bine byubuyobozi: hejuru-imbaraga-imbaraga-hasi-hasi-hasi.Muri iki gihe, icyerekezo kiranga impedance yicyiciro cyo hejuru ni microstrip umurongo wicyitegererezo hamwe nindege yimbaraga nkindege yerekanwe.

6. Ese amanota yikizamini ashobora guhita atangwa na software ku mbaho ​​zicapye cyane mu bihe bisanzwe kugirango zuzuze ibisabwa kugirango umusaruro ukorwe?
Mubisanzwe, niba software ihita itanga amanota yikizamini kugirango yuzuze ibisabwa byikizamini biterwa nuburyo ibisobanuro byongeweho amanota yikizamini byujuje ibisabwa mubikoresho byikizamini.Mubyongeyeho, niba insinga ari nyinshi kandi amategeko yo kongeramo amanota yikizamini arakomeye, ntaburyo bwo guhita wongera amanota yikizamini kuri buri murongo.Birumvikana, ugomba kuzuza intoki ahantu hagomba kugeragezwa.

7. Kongera amanota yikizamini bizagira ingaruka kumiterere yibimenyetso byihuta?
Niba bizagira ingaruka kumiterere yikimenyetso biterwa nuburyo bwo kongeramo amanota yikizamini nuburyo ibimenyetso byihuta.Mubusanzwe, amanota yinyongera (ntukoreshe ibihari ukoresheje cyangwa DIP pin nkibizamini) ushobora kongerwaho umurongo cyangwa gukuramo umurongo mugufi kuva kumurongo.
Iyambere ihwanye no kongeramo ubushobozi buke kumurongo, mugihe icya nyuma ari ishami ryiyongera.Ibi bintu byombi bizagira ingaruka ku kimenyetso cyihuta cyane cyangwa gito, kandi urugero rwingaruka zijyanye numuvuduko wikimenyetso cyikimenyetso nigipimo cyikimenyetso.Ubunini bwingaruka burashobora kumenyekana hakoreshejwe kwigana.Ihame, ntoya yibizamini, nibyiza (birumvikana ko bigomba kuba byujuje ibisabwa byigikoresho cyikizamini) bigufi ishami, nibyiza.
