Ma ke kaʻina hana PCB hoʻolālā, inā hiki ke wānana ʻia nā pōpilikia ma mua a hōʻalo ʻia i mua, e hoʻomaikaʻi nui ʻia ka helu kūleʻa o ka hoʻolālā PCB. Loiloi nā hui he nui i nā papahana me kahi hōʻailona o ka helu kūleʻa o kahi papa hoʻolālā PCB.

ʻO ke kī e hoʻomaikaʻi ai i ka helu kūleʻa o kahi papa ka hoʻolālā pono kīnā. I ka hoʻolālā ʻōnaehana uila o kēia manawa, nui nā hoʻolālā huahana, ua hana nā mea hana chipila, e like me ka chip e hoʻohana ai, pehea e kūkulu ai i ke kaapuni ākea a pēlā aku. ʻO ka hapa nui o ka manawa, ʻaʻohe pono nā ʻenekini lako pono e noʻonoʻo i ka pilikia o ke kaʻina kaapuni, pono e hana i kā lākou PCB ponoʻī.

Eia nō naʻe, aia i loko o ka hoʻolālā hoʻolālā PCB i loaʻa i nā ʻoihana he nui i nā pilikia, kūpaʻa ʻole ka hoʻolālā PCB, a holo ʻole paha. No nā ʻoihana nui, hāʻawi nā mea hana ʻāpana he nui i ke kākoʻo ʻenehana a me ke alakaʻi ma ka hoʻolālā PCB. Akā ke paʻakikī nei kekahi mau ʻoihana liʻiliʻi a me ka liʻiliʻi i kēlā kākoʻo. No laila, pono ʻoe e ʻimi i kahi ala e hana ai iā ʻoe iho, kahi e alakaʻi ai i nā pilikia he nui, e koi ana paha i nā mana he nui a me ka manawa lōʻihi o ka debugging. I ka ʻoiaʻiʻo, inā maopopo iā ʻoe ke ʻano hoʻolālā o ka ʻōnaehana, hiki ke hōʻalo i kēia. Here are three tips for reducing PCB design risk.

1, the system planning stage is best to consider the problem of signal integrity, the whole system is built like this, the signal from one PCB to another PCB can receive correctly? Pono e loiloi i kēia i ka wā mua, a ʻaʻole paʻakikī e loiloi i ka pilikia. ʻO kahi ʻike iki o ka pono o ka hōʻailona a me kekahi mau hana polokalamu maʻalahi hiki ke hana ia.

Second, in the PCB design process, the use of simulation software to evaluate the specific wiring, observe whether the signal quality can meet the requirements, the simulation process itself is very simple, the key is to understand the principle of signal integrity knowledge, and used for guidance.

Third, in the process of PCB, we must carry out risk control. Nui nā pilikia, ʻaʻohe ala o ka polokalamu simulate e hoʻonā ai, pono e kaohi ʻia e ka mea hoʻolālā. ʻO ke kī o kēia kaʻina e hoʻomaopopo i kahi o nā pilikia a me nā mea e hana ai e hōʻalo iā lākou, me ka ʻike hou o ka pono kīnā.

Inā hiki ke kiʻi maikaʻi ʻia nā helu ʻekolu i ke kaʻina hoʻolālā PCB, a laila e hoʻēmi nui ʻia ka hoʻolālā PCB, e ʻoi aku ka liʻiliʻi o ka hemahema ma hope o ka huki ʻana o ka papa i hope, a maʻalahi ka debugging.
