He aha ka hoʻopaʻa ʻana?
ʻO Stack-up e pili ana i ka hoʻonohonoho ʻana o nā ʻāpana keleawe a me nā papa insulating e hana i kahi PCB ma mua o ka hoʻolālā ʻana o ka papa.ʻOiai ʻo kahi papa hoʻonohonoho e hiki ai iā ʻoe ke loaʻa i ka circuitry hou aʻe ma ka papa hoʻokahi ma o nā ʻāpana papa PCB like ʻole, ʻo ke ʻano o ka hoʻolālā ʻana o ka PCB stackup e hāʻawi i nā pono ʻē aʻe he nui:
• Hiki ke kōkua i ka puʻupuʻu PCB e hōʻemi i ka nāwaliwali o kāu kaapuni i ka walaʻau o waho e like me ka hōʻemi ʻana i ka pāhawewe a hoʻemi i ka hopohopo impedance a me ka crosstalk ma nā papa hana PCB kiʻekiʻe.
• Hiki ke kōkua i ka hoʻopaʻa ʻana PCB papa maikaʻi iā ʻoe e kaulike i kāu mau pono no nā kumu kūʻai haʻahaʻa a maikaʻi hoʻi me nā hopohopo e pili ana i nā pilikia hōʻailona hōʻailona.
• Hiki ke hoʻonui i ka Electromagnetic Compatibility o kāu hoʻolālā.
E pōmaikaʻi pinepine ʻoe i ka ʻimi ʻana i kahi hoʻonohonoho PCB i hoʻopaʻa ʻia no kāu mau noi e pili ana i ka papa kaapuni paʻi.
No nā PCB multilayer, loaʻa nā papa ākea i ka mokulele honua (plane GND), ka mokulele mana (plane PWR), a me nā papa hōʻailona o loko.Eia kahi laʻana o kahi 8-layer PCB stackup.
Hāʻawi ʻo ANKE PCB i nā papa kaapuni multilayer / kiʻekiʻe ma ka laulā mai 4 a 32 papa, ka mānoanoa o ka papa mai 0.2mm a 6.0mm, keleawe mānoanoa mai 18μm a 210μm (0.5oz a 6oz), ka mānoanoa keleawe o loko mai 18μm a 70μm (0.5μm (0.5μm). oz a 2oz), a me ka liʻiliʻi o ka mamao ma waena o nā papa a hiki i 3mil.
