Hoʻohoka pinepine nā Newbies iā “PCB schematic” with “PCB design document” when talking about printed circuit boards, but they actually mean different things. ʻO ka hoʻomaopopo ʻana i nā ʻokoʻa ma waena o lākou ke kī i ka hana PCB kūleʻa, no laila e wāwahi kēia ʻatikala i nā ʻokoʻa nui ma waena o nā hoʻolālā PCB a me ka hoʻolālā PCB no nā mea hoʻomaka e hana i kēia ʻoi aku ka maikaʻi.

Ma mua o ke komo ʻana i nā ʻokoʻa ma waena o nā skema a me ka hoʻolālā, he mea nui ia e ʻike, he aha ia PCB? Inside electronic equipment, there are printed circuit boards, also known as printed circuit boards. The green circuit board, made of precious metal, connects all the electrical components of the device and enables it to function properly. ʻAʻole e holo ka uila i ʻole PCBS.

ʻO ke kiʻi hoʻolālā PCB a me ka hoʻolālā PCB

ʻO ka skema PCB kahi hoʻolālā kaapuni ʻelua dimensional maʻalahi e hōʻike ana i ka hana a me ka pilina ma waena o nā mea like ʻole. ʻO ka hoʻolālā PCB kahi hoʻolālā ʻekolu-dimensional, i mea e hōʻoia ai i ka hana maʻamau o ke kaapuni ma hope o ka māka ʻana i kahi o nā ʻāpana.

Therefore, PCB schematic is the first part of the design of printed circuit board. He hōʻailona kiʻi kēia, inā he palapala a ʻikepili paha, e hoʻohana ana i nā hōʻailona i ʻae ʻia e wehewehe i nā pilina kaapuni. Kuhi pū kekahi ia i nā mea e hoʻohana ai a pehea lākou e kaulaʻi ai.

As the name implies, a PCB schematic is a plan, a blueprint. ʻAʻole ia e kikoʻī i kahi e waiho ai i nā ʻāpana. Ma kahi o ka ʻōnaehana e hōʻike ana pehea e hoʻokō ai ka PCB i ka pilina a hana i kahi ʻāpana nui o ka hana hoʻolālā.

Ke pau nā blueprint, hele mai ka hoʻolālā PCB hou. Design is the layout or physical representation of the PCB schematic, including copper wiring and hole layout. Hōʻike ka hoʻolālā PCB i kahi o nā ʻāpana a me kā lākou pili i ke keleawe.

PCB design is a performance-related phase. Ua kūkulu nā ʻenekinia i nā ʻāpana maoli ma luna o nā hoʻolālā PCB, e ʻae iā lākou e hōʻoia inā i hana pono nā lako. E like me ka mea i ʻōlelo ʻia ma mua, pono i kekahi e hoʻomaopopo i ka ʻōnaehana PCB, akā ʻaʻole maʻalahi e hoʻomaopopo i kāna hana ma ka nānā ʻana i ka prototype.

Both phases are complete, and once you are satisfied with the PCB’s performance, you need to implement them through the manufacturer.

Nā mea hoʻolālā PCB

I kēia manawa maopopo iā mākou nā ʻokoʻa ma waena o nā mea ʻelua, e nānā pono i nā mea o ka hoʻolālā PCB. E like me kā mākou i ʻōlelo ai, ʻike ʻia nā pilina āpau, akā aia kekahi mau ana e hoʻomanaʻo ai:

In order to see the connections clearly, they are not created to scale; I ka hoʻolālā PCB, hiki iā lākou ke pili loa kekahi i kekahi

Hiki ke kuʻi kekahi i kekahi i kekahi, kahi hiki ʻole

Aia paha kekahi mau pilina ma nā ʻaoʻao ʻaoʻao o ka hoʻonohonoho, me nā māka e hōʻike ana ua hoʻopili ʻia

Hiki i kēia PCB “blueprint” kahi ʻaoʻao, ʻelua ʻaoʻao, a i ʻole kekahi mau ʻaoʻao e wehewehe ana i nā mea āpau e pono ai e hoʻokomo i ka hoʻolālā.

ʻO kahi kiko hope loa e kahakaha ʻo ia nā skema maʻalahi aʻe e hiki ke hōʻuluʻulu ʻia e ka hana e hoʻomaikaʻi i ka heluhelu. Arranging connections in this way does not occur at the next stage, and the schematic usually does not match the final design of the 3D model.

Nā Huahana Hoʻolālā PCB

ʻO ka manawa kēia e nānā pono ai i nā mea o ka palapala hoʻolālā PCB. I kēia manawa neʻe mākou mai nā blueprints i kākau ʻia i nā hōʻike kino i kūkulu ʻia me ka hoʻohana ʻana i ka lamineka a me nā mea pālolo. Hoʻohana ʻia ka PCBS maʻalahi no nā noi ʻoi aku ka paʻakikī kahi e koi ʻia ai kahi wahi kuikahi.

ʻO ka ʻike o ka palapala hoʻolālā PCB e pili ana i ka blueprint i waiho ʻia e ke kaʻina hana, akā, e like me ka mea i ʻōlelo ʻia ma mua, ʻokoʻa ʻokoʻa ka nānā ʻana o nā mea ʻelua. Ua kūkākūkā mua mākou i nā skema PCB, akā he aha nā ʻokoʻa e hiki ke nānā ʻia i ka palapala hoʻolālā?

Ke kamaʻilio mākou e pili ana i kahi palapala hoʻolālā PCB, ke kamaʻilio nei mākou e pili ana i kahi hiʻohiʻona 3D e hoʻopili ana i ka papa kaapuni i paʻi ʻia a me ka palapala hoʻolālā. Hiki iā lākou ke lilo i hoʻokahi a i ʻole multi-layered, ʻoiai ʻelua mau papa ka mea maʻamau. Hiki iā mākou ke nānā i kekahi mau ʻokoʻa ma waena o nā skema PCB a me nā palapala hoʻolālā PCB:

Hoʻonohonoho pono ʻia nā mea āpau a hoʻonohonoho ʻia

Inā ʻaʻole pono e hoʻopili i nā kiko ʻelua, pono lākou e kaʻi a i ʻole hoʻohuli ʻia i kahi papa PCB ʻē aʻe e pale i ka hele ʻana i kekahi i kekahi ma ka papa like.

Hoʻohui ʻia, e like me kā mākou kūkā kamaʻilio pōkole ʻana, ʻoi aku ka hopohopo o ka hoʻolālā PCB me ka hana maoli, no ka mea, ʻo kēia kekahi o ka pae hōʻoia o ka huahana hope loa. I kēia manawa, pono e hoʻokomo i ka pono o ka hana maoli o ka hoʻolālā, a pono e noʻonoʻo ʻia nā koi kino o ka papa kaapuni paʻi. ʻO kekahi o ia mau mea:

How is the spacing of the components allowed for adequate heat distribution

Aia nā mea hoʻopili a puni nā lihi

I ke ʻano o kēia a me ka wela, pehea ka mānoanoa o nā kaha like ʻole

Ma muli o nā palena o ke kino a me nā koi i ka nānā pinepine ʻana o nā palapala hoʻolālā PCB i ka hoʻolālā ʻokoʻa ma ka papahana, aia nā palapala hoʻolālā i nā papa paʻi silkscreen. Hōʻike ka papa paʻi paʻi i nā leka, nā helu a me nā hōʻailona e kōkua i nā ʻenekini e ʻākoakoa a hoʻohana i ka papa.

It is required that all components work as planned after being assembled onto the printed circuit board. Inā ʻaʻole, pono e hana hou.

ka hopena

ʻOiai huikau pinepine nā palapala hoʻolālā PCB a me nā palapala hoʻolālā PCB, hana maoli i nā hoʻolālā PCB a me ka hoʻolālā PCB i ʻelua kaʻina kaʻawale ke hana nei i kahi papa paʻi. PCB design, which is an important part of PCB performance and integrity, must be made prior to the creation of a PCB schematic diagram that can draw the process flow.
