Ke hoʻolauna nei i kā mākou huahana hou loa, he 16-layer rigid-flex board PCB i hoʻolālā ʻia no nā noi aerospace pūʻali koa. Me kona mau hiʻohiʻona kiʻekiʻe a me ka hana kiʻekiʻe, ua hoʻololi kēia huahana i ka ʻoihana.

Hana ʻia ka papa 16-layer rigid-flex PCB me ka hoʻohana ʻana i ka ʻenehana kiʻekiʻe e hōʻoia i ka paʻa a me ka hilinaʻi ʻoiai i nā wahi koi nui loa. Aia nā papa i ka laulā laina 0.15mm/0.15mm a me ka spacing no nā pili pololei a pololei. ʻO ka 2.0MM + -10% ka mānoanoa pāʻani e hōʻoia i ka paʻa a me ka paʻa, i mea kūpono no nā noi papa koa.

Hiki i ka 5+6+5 stackup ke hoʻouna i ka hōʻailona kūpono a me ka mana impedance, e hōʻoia i ka hana maikaʻi loa. ʻO ka liʻiliʻi liʻiliʻi o ka aperture o 0.2mm e hiki ai i ka hoʻokele hōʻailona kūpono a hoʻonui i ka maʻalahi o ka hoʻolālā. Hāʻawi ka 35UM keleawe ma o ka mānoanoa i ka conductivity ikaika a hōʻoia i ka hana mau.

I mea e hoʻonui ai i ke ola lawelawe o ka huahana, hoʻohana ka 16-layer soft-hard board i ka ENIG 2-3uin surface treatment. Mālama kēia lāʻau i ka papa kaapuni mai ka corrosion a me ka oxidation, e hoʻolōʻihi i kona ola lawelawe. Eia kekahi, loaʻa i ka papa ka helu warpage e like me ka haʻahaʻa e like me ≤0.5%.
