 He aha ka High Speed ​​PCB?

ʻO ka "High Speed" ka mea maʻamau i ke ʻano o nā kaapuni kahi i ʻoi aku ai ka lōʻihi o ka piʻi ʻana a i ʻole ka hāʻule ʻana o ka hōʻailona ma mua o hoʻokahi hapaono o ka lōʻihi o ka laina hoʻouna ʻoi aku ka lōʻihi ma mua o ka lōʻihi o ka laina hoʻouna, a laila hōʻike ka lōʻihi o ka laina hoʻouna i ke ʻano o ka laina lumped.

Ma kahi PCB wikiwiki loa ka manawa ala e hiki ai i ka bandwidth no ka hōʻailona kikohoʻe ke hoʻonui i nā alapine kiʻekiʻe MHz a i ʻole GHz. Ke hana ʻia kēia, aia kekahi mau pilikia hōʻailona e ʻike ʻia inā ʻaʻole i hoʻolālā ʻia kahi papa me ka hoʻohana ʻana i nā lula hoʻolālā PCB kiʻekiʻe. ʻO ka mea nui, ʻike paha kekahi:

1. Uncceptably nui transient kani. Hana ʻia kēia i ka wā ʻaʻole ākea nā traces, ʻoiai pono ʻoe e makaʻala i ka hoʻonui ʻana i kāu mau traces (e ʻike i ka ʻāpana o Impedance Contorl i ka PCB Design ma lalo). Inā ʻoi aku ka nui o ke kani transient, loaʻa iā ʻoe ka overshoot nui a i ʻole undershoot i kāu hoʻololi hōʻailona.

2.Strong crosstalk. Ke piʻi aʻe ka wikiwiki o ka hōʻailona (ʻo ia hoʻi, i ka emi ʻana o ka manawa piʻi), hiki i ka capacitive crosstalk ke lilo i mea nui e like me ka ʻike ʻana i kēia manawa i ka capacitive impedance.

3. Hoʻopau nā mea hoʻokele a me nā mea hoʻokipa. Hiki i kāu mau hōʻailona ke noʻonoʻo i nā mea ʻē aʻe ke loaʻa kahi impedance mismatch. Inā lilo ka impedance mismatch i mea koʻikoʻi e pono e nānā i ka impedance hoʻokomo, hoʻouka impedance, a me ka laina hoʻoili impedance hiʻona no kahi pilina. Hiki iā ʻoe ke heluhelu hou aku e pili ana i kēia ma ka ʻāpana aʻe.

4. Power integrity pilikia (transient PDN ripple, ground bounce, etc.). ʻO kēia kekahi pūʻulu o nā pilikia hiki ʻole ke pale ʻia i kekahi hoʻolālā. Eia nō naʻe, hiki ke hoʻemi nui ʻia ka ripple PDN transient a me nā EMI e hiki mai ana ma o ka hoʻolālā stackup kūpono a me nā ana decoupling. Hiki iā ʻoe ke heluhelu hou aʻe e pili ana i ka hoʻolālā stackup PCB kiʻekiʻe ma hope o kēia alakaʻi.

5. EMI ikaika i alakaʻi ʻia a hoʻomālamalama ʻia. ʻO ke aʻo ʻana o ka hoʻoponopono ʻana i nā pilikia EMI he nui, ma ka pae IC a me ka pae hoʻolālā PCB kiʻekiʻe. ʻO ka EMI he kaʻina hana pānaʻi; inā ʻoe e hoʻolālā i kāu papa e loaʻa i ka palekana EMI ikaika, a laila e hoʻemi ʻia ka EMI. Eia hou, ʻo ka hapa nui o kēia i ka hoʻolālā ʻana i ka stackup PCB kūpono.

Hāʻawi pinepine nā PCB kiʻekiʻe i kahi alapine mai 500MHz a 2 GHz, hiki ke hoʻokō i nā pono o nā hoʻolālā PCB kiʻekiʻe, microwave, radiofrequency, a me nā noi kelepona. Ke piʻi ka alapine ma luna o 1 GHz, hiki iā mākou ke wehewehe i ke alapine kiʻekiʻe.

Ke piʻi mau nei ka paʻakikī o nā ʻāpana uila a me nā hoʻololi i kēia mau lā a pono ka wikiwiki o ka kahe o ka hōʻailona. No laila, koi ʻia nā alapine hoʻoili kiʻekiʻe. Kōkua nui nā PCB kiʻekiʻe i ka hoʻohui ʻana i nā koi hōʻailona kūikawā i nā ʻāpana uila a me nā huahana me nā pono e like me ke kiʻekiʻe o ka pono, a me ka wikiwiki wikiwiki, haʻahaʻa attenuation, a me nā waiwai dielectric mau.

Hoʻohana nui ʻia nā PCB kiʻekiʻe i ka lekiō a me ka wikiwiki kiʻekiʻe, e like me 5G kelepona ʻole, nā mea ʻike radar automotive, aerospace, satellite, a me nā mea ʻē aʻe.

· Hoʻolālā ʻāpana-nui

Hoʻohana maʻamau mākou i nā PCB multi-layered i nā hoʻolālā PCB kiʻekiʻe. ʻO nā PCB i hoʻohui ʻia he hui nui a me ka liʻiliʻi liʻiliʻi, e kūpono loa iā lākou no nā pūʻolo hopena. A ua maʻalahi nā papa multi-layer e hoʻopōkole i nā pilina ma waena o nā mea uila a hoʻomaikaʻi i ka wikiwiki o ka hoʻouna ʻana i nā hōʻailona.

ʻO ka hoʻolālā mokulele honua kahi mea nui o nā noi kiʻekiʻe no ka mea ʻaʻole ia e mālama i ka maikaʻi o ka hōʻailona akā kōkua pū kekahi i ka hōʻemi ʻana i nā radiations EMI.

1. Hoʻololi ʻia ka permittivity.

2.Low attenuation no ka hoʻouna hōʻailona kūpono.

3.Homogeneous hana me ka haʻahaʻa tolerances i insulation mānoanoa a me ka dielectric mau. Ke piʻi wikiwiki nei ka noi no nā huahana PCB kiʻekiʻe a me ka wikiwiki i kēia mau lā. Ma ke ʻano he mea hana PCB Hookah , ke kālele nei ʻo YMS i ka hāʻawi ʻana i nā mea kūʻai aku me ka hilinaʻi kiʻekiʻe-frequency PCB prototyping me ke ʻano kiʻekiʻe. Inā loaʻa iā ʻoe kekahi pilikia me ka hoʻolālā PCB a i ʻole ka hana PCB, e ʻoluʻolu e kelepona mai iā mākou.
