ʻO ka papa kaapuni paʻi (Printed circuit board, i kapa ʻia ʻo PCB) he substrate no ka hui ʻana i nā ʻāpana uila, a he papa paʻi ia e hana ana i nā pili kiko-i-point a me nā ʻāpana i paʻi ʻia ma kahi substrate maʻamau e like me ka hoʻolālā i koho mua ʻia.ʻO ka hana nui o ka PCB ʻo ia ka hana ʻana i nā ʻano mea uila e hana i kahi pilina kaapuni i koho mua ʻia, e pāʻani i ke kuleana o ka hoʻouna ʻana i ka relay, ʻo ia ke kī uila uila o nā huahana uila.
ʻO ka maikaʻi o ka hana ʻana o nā papa kaapuni paʻi ʻaʻole pili wale i ka hilinaʻi o nā huahana uila, akā pili pū kekahi i ka hoʻokūkū holoʻokoʻa o nā huahana ʻōnaehana, no laila ua ʻike ʻia ʻo PCB ʻo ka "makuahine o nā huahana uila".
I kēia manawa, ʻo nā ʻano huahana uila like ʻole e like me nā kamepiula pilikino, kelepona paʻalima, nā kāmela kikohoʻe, nā mea uila, nā mea hoʻokele ukali kaʻa, nā ʻāpana kaʻa a me nā kaʻa ʻē aʻe, hoʻohana nā mea a pau i nā huahana PCB, hiki ke ʻike ʻia ma nā wahi āpau o ko mākou ola i kēlā me kēia lā.
Me ke ʻano hoʻolālā o nā hana like ʻole, ka miniaturization a me ke kaumaha māmā o nā huahana uila, ua hoʻohui ʻia nā mea liʻiliʻi liʻiliʻi i ka PCB, ua hoʻohana hou ʻia nā papa, a hoʻonui pū ka hoʻohana ʻana o ka hāmeʻa, e paʻakikī ana ka noi ʻana o PCB.
ʻO ka PCB kaʻawale Papa ma o SMT (surface mount technology) nā ʻāpana, a i ʻole ma o DIP (double in-line package) plug-in plug-in i ke kaʻina holoʻokoʻa, i kapa ʻia ʻo PCBA (Printed Circuit Board Assembly).
