I-CCL (COPPER CLAD Laminate) ukuthatha isikhala esisele kwi-PCB njengezinga lesethenjwa, bese uligcwalisa nge-Copper eliqinile, elaziwa nangokuthi ithusi eliqinile.

Ukubaluleka kwe-CCL njengoba ngezansi:

1. Yehlisa amandla emhlabathini futhi uthuthukise ikhono lokulwa nokuphazamiseka
2. Yehlisa ukwehla kwamandlalaji futhi uthuthukise ukusebenza kwamandla
3. Ixhunywe emhlabathini futhi inganciphisa nendawo ye-loop.

Njengokuxhumanisa okubalulekile kwe-PCB Design, kungakhathalekile ukuthi i-software design ye-Qingyue Feng PCB ye-Qingyue Feng, futhi i-PowerPCB inikeze umsebenzi oqondayo wethusi, ukuze usebenzise kanjani ithusi elilungile, ngiyokwabelana ngemibono yami embonini.

Manje ukuze wenze i-PCB welding ngangokunokwenzeka ngaphandle kokuguquguquka, iningi labakhiqizi be-PCB lizodinga futhi umklami we-PCB ukugcwalisa indawo evulekile ye-PCB noma nge-wire yomhlaba enjenge-grid-efana. Uma i-CCL ingaphathwa kahle, kuzoholela emiphumeleni emibi kakhulu. Ingabe i-ccl "ilungile kunokulimala" noma "kubi kakhulu kunokuhle"?

Ngaphansi kwesimo semvamisa ephezulu, kuzosebenza kwi-capacitance ye-wiring ephrintiwe ephrintiwe, lapho ubude bungaphezulu kwe-1/10 ye-antenna yomsindo, uma kukhona ithuluzi lokuhambisa, uma kuthola ithuluzi le-antenna, uma kuthola ithuluzi le-antenna, ungakholelwa ukuthi uxhuma i-wire komhlaba phansi endaweni ethile, yilokhu "Ground", eqinisweni, kumele kube ngaphansi kwesikhala se-λ / 20, punch umgodi endizeni e-cabling and multilayer tortening " Uma i-CCL ihlolwe kahle, ayikwazi ukukhulisa okwamanje, kepha futhi idlale indima ebili yokuphazamiseka.

Kunezindlela ezimbili eziyisisekelo ze-CCL, okungukuthi indawo enkulu ye-Copper Cropper kanye ne-mesh yethusi, kuvame ukubuzwa, okuyinto ehamba phambili, kunzima ukusho. Ngani? Indawo enkulu ye-CCL, ngokwanda kwendima embaxambili yamanje nokuvikelwa, kepha kunendawo enkulu ye-CCL, iBhodi ingahle iphinde isheshe isheshe, kusukela ekubumbeni kokushisa kwegagasi, i-GRID inezinzuzo (kunciphisa indawo yokushisa yethusi) futhi wadlala indima ethile yokuvikelwa kwe-electromagnetic. Kepha kufanele kuboniswe ukuthi igridi yenziwa ngokushintshana ngokuhlangene kokugijima, isikhathi sobubanzi be-Work Frequency of the Circuit Board, uma usayizi osebenza ngokufana, uma usayizi wokusebenza ohlukaniswe yisikhathi esisebenzayo, uma usayizi wokusebenza kanye nokuhambisana okujwayelekile, uzothola ukuthi umjikelezo ngeke asebenze Ngokufanelekile, uhlelo lokuphazamiseka kokuphuma kokuphazanyiswa lusebenza yonke indawo.Kodwa, kulabo abasebenzisa iGridi, izeluleko zami ukukhetha okukodwa kwegridi ye-multiit board, umjikelezo wemvamisa ophansi onesifunda esiphakeme samanje kanye nezinye ithusi eliphelele eliphelele.

E-CCL, ukuze kuvunyelwe ukuthi kufinyelelwe umphumela wakithi okulindelekile, khona-ke izici ze-CCL zidinga ukunaka ukuthi ziphi izinkinga:

1. Uma umhlabathi we-PCB uphezulu, ube ne-SGND, AGND, GND, njll. isakhiwo.

2. Okokuxhumana okukodwa kwamaphoyinti wezindawo ezahlukahlukene, indlela ukuxhuma ngokumelana no-0 Ohm noma ubuhlalu obunamandla noma ukuwohloka;

3. CCL eduze ne-crystal oscillator. I-Crystal Oscillator ekujikelezeni ingumthombo wokuphuma okuthe xaxa. Indlela ukuzungeza i-crystal oscillator nge-cryper clodding bese ibeka phansi igobolondo le-crystal oscillator ngokwahlukana.

4.Ubunzima bendawo efile, uma uzizwa mkhulu kakhulu, bese wengeza emhlabathini ngeyo.

I-5. Ekuqaleni kwe-wiring, kufanele iphathwe ngokulinganayo ngenxa ye-wiring emhlabathini, kufanele singenwe inhlabathi kahle lapho i-wiring, ayikwazi ukuthembela ekuqedeni i-vias uma iqeda i-ccl ukuqeda i-PIN yemhlaba lapho kuxhunywa, lo mphumela mubi kakhulu.

I-6. Kungcono ukuthi ungabi ne-angle ebukhali ebhodini (= 180 °), ngoba kusuka endaweni yokubukwa kwe-electromagnetism, lokhu kuzokwakha i-antenna, ngakho-ke ngiphakamisa ukusebenzisa imiphetho ye-arc.

7

8.Insimbi ngaphakathi kwemishini, njenge-radiator yensimbi, umucu wokuqinisa insimbi, kufanele uzuze "isisekelo esihle".

9.I-block epholile yensimbi ye-voltage voltage stabilizer nebhande lokuhlukaniswa eliseduze eduze neCrystal Oscillator kumele isungulwe kahle. Ngegama: I-CCL kwi-PCB, uma inkinga yesisekelo isingathwa kahle, kufanele ibe "yinhle kakhulu kunalokho okubi", kunganciphisa inqwaba ye-backFlow yangaphandle.
