Ngokuvamile, izici ezithinta isimilo se-PCB yilezi: ukuqina kwe-dielectric th, ukulandelela ububanzi be-T, ukulandelela u-W, ukulandelela ukulandelwa kwe-distenting, ubukhulu bemibhalo ekhethiwe ye-solder mask.

Ngokuvamile, ubukhulu bokuhlukaniswa kwe-dielectric kanye nokuhlukaniswa komugqa, kukhulu inani lokubulawa kwabantu; Uma kukhudlwana i-dielectric njalo, ubukhulu bethusi, ububanzi bekholi, nobubanzi bama-mask borde, obuncane kakhulu.

Esokuqala: ubukhulu obuphakathi, ukwanda ubukhulu obuphakathi kungakhulisa ukungavikeleki, futhi kunciphise ubukhulu obuphakathi bunganciphisa ukungavikeleki; Ama-prepregs ahlukene anokuqukethwe okuhlukile kwe-glue kanye nobukhulu. Ubukhulu ngemuva kokucindezela buhlobene nokufuya kwabezindaba kanye nenqubo yepuleti elicindezelayo; Noma yiluphi uhlobo lwepuleti olusetshenzisiwe, kuyadingeka ukuthola ubukhulu be-media ungqimba olungakhiqizwa, okulungele ukuklama ukubalwa, kanye nokwakhiwa kobunjiniyela, ukucindezela ipuleti, ukubekezelela ipuleti kuyisihluthulelo sokulawulwa kwemidiya.

Okwesibili: Ububanzi be-Line, ukukhulisa ububanzi belayini kunganciphisa ukungavikeleki, ukunciphisa ububanzi belayini bungangezela ukungavikeleki. Ukulawulwa kobubanzi bomugqa kudinga ukubekezelelana kwe- +/- 10% ukufeza ukulawulwa kwe-impedance. Igebe lomugqa wesiginali lithinta wonke ama-waveform wokuhlola. Ukulimala kwalo okukodwa kuphakeme, okwenza lonke i-waveform kungalingani, futhi umugqa wokuvikela awuvunyelwe ukwenza umugqa, igebe alikwazi ukwedlula i-10%. Ububanzi be-Line bulawulwa ngokukhethekile ngokulawulwa kwe-etching. Ukuze uqinisekise ububanzi bentambo, ngokuya ngenani le-etching side etching, iphutha lokudweba elikhanyayo, nephutha lokudlulisela iphethini, i-provel film inxephekwe ngenqubo yokuhlangabezana nemfuneko ye-Line Fourth.

Okwesithathu: ubukhulu bethusi, ukunciphisa ukuqina komugqa kungangezelela ukungavikeleki, ukukhulisa ubukhulu bomugqa kunganciphisa ukungavikeleki; Ukuqina komugqa kungalawulwa nge-planing yephethini noma ukukhetha ubukhulu obuhambisanayo besisekelo se-foil foil. Ukulawulwa kokuqina kwethusi kuyadingeka ukuba ube umfaniswano. I-shunt block ingezwa ebhodini lezintambo ezincanyana nezintambo ezihlukanisiwe ukulinganisa okwamanje ukuvikela ubukhulu bethusi ongalingani ocingweni futhi kuthinte ukusatshalaliswa okungalinganiswa kwethusi ngezindawo ze-CS nase-SS. Kuyadingeka ukuwela iBhodi ukufeza inhloso yobukhulu bethusi elifanayo ezinhlangothini zombili.

Okwesine: I-Dielectric ihlala njalo, ukukhulisa i-dielectric njalo kunganciphisa ukungahambi kahle, ukunciphisa i-dielectric njalo kungakhulisa ukungasebenzi, i-dielectric njalo ilawulwa yilokho okuqukethwe. I-dielectric njalo yamapuleti ahlukene ihlukile, okuhlobene ne-resin impahla esetshenzisiwe: I-dielectric ihlala i-PTFE Plate ingu-3.9- ukuthola inani eliphakeme lokususa phakathi kwe-3.9 lidinga i-dielectric ephansi ephansi.

Owesihlanu: ubukhulu be-mask yomthengisi. Ukuphrinta imaskhi yomthengisi kuzonciphisa ukumelana kwesendlalelo sangaphandle. Ngaphansi kwezimo ezijwayelekile, ukuphrinta imaski eyodwa eyodwa ye-solder kunganciphisa ukwehla okukodwa ngama-2 ohms, futhi kungenza ukwehla okuhlukile ngama-8 ohms. Ukuphrinta kabili inani leconsi liphindwe kabili lokho kudlula okukodwa. Lapho unyathelisa kathathu, inani lokulimala ngeke liguquke.
