CCL (Umuringa Clad Laminate) nugufata umwanya wihariye kuri PCB nkurwego rwerekanwe, hanyuma ukuzuza umuringa ukomeye, uzwi kandi nko gusuka umuringa.

Ubusobanuro bwa CCL nkuko bikurikira:

1. gabanya inzitizi zubutaka no kunoza ubushobozi bwo kurwanya kwivanga
2. kugabanya imbaraga za voltage no kunoza imikorere
3. ihujwe nubutaka kandi irashobora kandi kugabanya ubuso bwumuzingi.

Nkumuhuza wingenzi wigishushanyo cya PCB, utitaye kumasosiyete yo mu bwoko bwa Qingyue Feng PCB yo gushushanya, hamwe na Protel yo mumahanga, PowerPCB yatanze imikorere yumuringa wubwenge, kuburyo bwo gukoresha umuringa mwiza, nzabagezaho bimwe mubitekerezo byanjye bwite, nizeye kuzana inyungu ku nganda.

Noneho kugirango ushobore gusudira PCB uko bishoboka kwose nta guhindagurika, abakora PCB benshi bazakenera kandi umushinga wa PCB kuzuza ahantu hafunguye PCB umuringa cyangwa insinga zimeze nka gride.Niba CCL idakozwe neza, bizagushikana kubisubizo bibi.CCL "nziza kuruta kugirira nabi" cyangwa "ibibi kuruta ibyiza"?

Ukurikije imiterere yumurongo mwinshi, bizakora kumurongo wacapwe wumuzunguruko wiring capacitance, mugihe uburebure burenze 1/20 cyumuvuduko wurusaku rujyanye nuburebure bwumuraba, noneho birashobora gutanga ingaruka za antenne, urusaku ruzatangira binyuze mumashanyarazi, niba hano haribintu bibi CCL muri PCB, CCL yabaye igikoresho cyurusaku rwogukwirakwiza, kubwibyo rero, mumuzunguruko mwinshi, ntukizere ko niba uhuza umugozi wubutaka nubutaka ahantu runaka, iyi ni "butaka", Mubyukuri , igomba kuba munsi yumwanya wa λ / 20, gukubita umwobo muri cabling hamwe nindege yubutaka bwinshi "ihagaze neza".Niba CCL ikemuwe neza, ntishobora kongera gusa ikigezweho, ariko kandi igira uruhare runini rwo gukingira kwivanga.

Hariho inzira ebyiri zifatizo za CCL, arizo nini nini zometseho umuringa hamwe nu muringa wa mesh, akenshi nazo zibazwa, niyihe nziza, biragoye kubivuga.Kubera iki?Agace kanini ka CCL, hamwe no kwiyongera kwubu no gukingira uruhare rwibiri, ariko hari ahantu hanini ha CCL, ikibaho gishobora guhinduka, ndetse kikaba kinini niba binyuze mukugurisha umuraba.Niyo mpamvu, muri rusange nazo zizafungura uduce duke kugirango tworohereze Uwiteka umuringa utubutse, mesh CCL irinda cyane, kongera uruhare rwumuyaga iragabanuka, Urebye uko ubushyuhe bwagabanijwe, gride ifite inyungu (igabanya ubushuhe bwumuringa) kandi yagize uruhare runini rwo gukingira amashanyarazi.Ariko twakagombye kwerekana ko gride ikorwa muburyo bwo guhinduranya icyerekezo cyo gukora, tuzi ubugari bwumurongo kumurongo wakazi wumurongo wumuzunguruko ufite uburebure bwa "amashanyarazi" buringaniye (ubunini nyabwo bugabanijwe numurongo wakazi wa digitale ihuye inshuro, ibitabo bifatika), mugihe inshuro zakazi zitari hejuru, birashoboka ko uruhare rwumurongo wa gride rutagaragara, iyo uburebure bwamashanyarazi hamwe nakazi gahuza bihuye, nibibi cyane, uzasanga umuzenguruko udakora neza, sisitemu yo kwangiza ibyuka bya sisitemu ikorera ahantu hose.Nuko rero, kubakoresha gride, inama nakugira ni uguhitamo ukurikije imiterere yakazi yimiterere yubuyobozi bwumuzunguruko, aho gufata ikintu kimwe.Nuko rero, ibisabwa byumuzunguruko mwinshi birwanya kwivanga kwa gride-intego nyinshi, umuzenguruko muke hamwe numuzunguruko mwinshi hamwe nibindi bisanzwe bikoreshwa byumuringa wuzuye.

Kuri CCL, kugirango ireke igere ku ngaruka twateganijwe, noneho ibintu bya CCL bigomba kwitondera ibibazo:

1. Niba ubutaka bwa PCB ari bwinshi, gira SGND, AGND, GND, nibindi, bizaterwa numwanya wubuyobozi bwa PCB, kugirango ukore "ubutaka" nyamukuru nkibisobanuro bya CCL yigenga, kuri digitale na kugereranya gutandukanya umuringa, mbere yo kubyara CCL, mbere ya byose, imigozi itinyutse ihuza amashanyarazi: 5.0 V, 3.3 V, nibindi, murubu buryo, umubare wuburyo butandukanye ugizwe nuburyo bwo guhindura ibintu.

2. Kubintu bimwe bihuza ahantu hatandukanye, uburyo nuguhuza binyuze muri 0 ohm irwanya cyangwa isaro ya magneti cyangwa inductance;

3. CCL hafi ya oscillator ya kristu.Oscillator ya kristu mumuzunguruko ni isoko yohereza imyuka myinshi.Uburyo nugukikiza oscillator ya kristu hamwe n'umuringa wambaye umuringa hanyuma ugahina igishishwa cya kristu oscillator ukwayo.

4.Ikibazo cya zone yapfuye, niba wumva ari kinini cyane, noneho ongeraho igitaka unyuzemo.

5. Mugutangira insinga, bigomba gufatwa kimwe kubutaka bwubutaka, tugomba kwifata hasi neza mugihe insinga, ntidushobora kwishingikiriza kongeramo vias iyo CCL irangiye kugirango ikureho pin yubutaka kugirango ihuze, iyi ngaruka ni nziza cyane bibi.

6. Nibyiza kutagira Inguni ikarishye kurubaho (= 180 °), kuko duhereye kuri electromagnetism, ibi bizakora antenne yanduza, ndasaba rero ko nkoresha impande za arc.

7. Igice kinini cyo hagati wiring ahantu hasigara, ntukore umuringa, kuko biragoye gukora CCL kugirango "ihagarare"

8.icyuma kiri mubikoresho, nka radiator yicyuma, umurongo wogukomeza ibyuma, bigomba kugera "kubutaka bwiza".

9.Icyuma gikonjesha icyuma cya terefegitatu ya voltage stabilisateur hamwe n'umukandara wo kwigunga hafi ya oscillator ya kristu igomba kuba ihagaze neza.Mu ijambo: CCL kuri PCB, niba ikibazo cyubutaka gikemuwe neza, kigomba kuba "cyiza kuruta ikibi", gishobora kugabanya umurongo wumurongo winyuma, kugabanya ibimenyetso byinjira mumashanyarazi.
