Pomwe kufunikira kwa kulumikizana kothamanga kwambiri kukupitilira kukula, kupita patsogolo kwaukadaulo waukadaulo wa lamination kumathandizira kuti ma waya amawu othamanga kwambiri mu PCBs okhazikika. Gwiritsani ntchito njira zotsogola monga njira zowongolera, njira zosiyanitsira, ndi mapangidwe a microstrip kapena mizere kuti musunge kukhulupirika kwa chizindikiro ndikuchepetsa kutayika kwa ma sign. Zolinga zamapangidwe zimaganiziranso zotsatira za kugwirizana, crosstalk, ndi kuwonetsera ma signal. Kugwiritsa ntchito zida zapadera ndi njira zopangira zimathandizira kukwaniritsa magwiridwe antchito othamanga kwambiri a PCB.
Kupita patsogolo kwaukadaulo wa rigid-flex lamination kukupangitsa kuti pakhale zida zamagetsi zowoneka bwino, zosinthika komanso zowoneka bwino. Kupita patsogolo kwazinthu zatsopano, mabwalo osindikizidwa a 3D, zida zokhazikika zokhazikika komanso njira zamakina othamanga kwambiri zimapatsa opanga kusinthasintha kwakukulu komanso mwayi wopanga mapangidwe apamwamba komanso odalirika a PCB. Pamene ukadaulo ukupitilirabe kusinthika, opanga ndi opanga akuyenera kukhala osinthika ndikugwira ntchito limodzi kuti atengere mwayi pazitukuko zaposachedwa ndikukwaniritsa magwiridwe antchito okhazikika a PCB.

Powombetsa mkota,kupanga ndi kusankha koyenera kokhazikika kokhazikika kwa PCB ndikofunikira kuti mukwaniritse magwiridwe antchito, kudalirika, ndi kusinthasintha. Poganizira zinthu monga kukhulupirika kwa ma siginecha, zofunikira zosinthika ndi zopinga zopanga, opanga amatha kukonza zosungirako kuti zikwaniritse zosowa zawo zenizeni. Kupita patsogolo kopitilira muyeso kwaukadaulo wazinthu kumapereka chiyembekezo chokulirapo cha kapangidwe kamagetsi kamakono. Zida zatsopano zopangira ma PCB okhwima zimasintha kusinthasintha, kulimba, komanso kutentha komanso kukana chinyezi. Kuphatikiza apo, kuphatikiza zigawo mwachindunji mu flex layer kumachepetsanso kukula ndi kulemera kwa PCB, ndikupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ndi zopinga zapakati. Kuphatikiza apo, kupita patsogolo kwaukadaulo wa lamination kumapereka mwayi wosangalatsa. Kugwiritsa ntchito ukadaulo wosindikiza wa 3D kumatha kupangitsa kuti pakhale zovuta kupanga komanso kuwongolera ma prototyping mwachangu komanso makonda.
Kuphatikiza apo, kupita patsogolo kwaukadaulo wowongolera ma siginecha othamanga kwambiri kumathandizira ma PCB okhazikika kuti akwaniritse kulumikizana koyenera komanso kodalirika.
Pamene ukadaulo ukupitilirabe kusinthika, opanga amayenera kudziwa zomwe zapita patsogolo komanso kugwirira ntchito limodzi ndi opanga. Potengera kupita patsogolo kwa zida ndi matekinoloje opangira, opanga amatha kupanga mapangidwe apamwamba komanso odalirika a PCB kuti akwaniritse zosowa zamakampani omwe amasintha nthawi zonse. Ndi lonjezo la mapangidwe apamwamba a zamagetsi, tsogolo la ma PCB osasunthika osasunthika likuwoneka bwino.
