Hana i Papa PCB ʻaʻole ia he hana maʻalahi e hoʻopiha i ka papa, ʻeli i kahi lua e kīkī i nā mea. ʻAʻole paʻakikī ka hana PCB, aia ka pilikia i ka troubleshooting ma hope o ka hana. Inā he hobbyists pākahi a ʻenekinia ʻoihana paha, he maʻi poʻo ke poʻo PCB, ʻo ka hoʻopili ʻana i nā pilikia, e like me nā programmer e hālāwai me nā pilikia.

Nui ka hoihoi o kekahi poʻe i ka hoʻopau ʻana i ka papa kaapuni PCB, e like me nā programmers i ka hoʻoponopono ʻana i nā pilikia, ʻaʻole iki nā pilikia maʻamau o ka papa kaapuni PCB, nā pilikia maʻamau ma ka hoʻohui ʻana i ka hoʻolālā papa kaapuni, ka hōʻino ʻana i nā pono uila, ka pōʻai kaapuni, ka maikaʻi o nā mea. , ‘Aʻole hapa iki ka hewa hoʻokaʻawale papa PCB.

Pehea e ʻike ai i ka holo pono ʻole o ka papa PCB

ʻO ka mea pale kala kala diode ʻino

Hoʻonohonoho pinepine ʻia nā hewa PCB kaapuni papa ma nā ʻāpana, e like me capacitance, resistence, inductance, diode, transistor, field effect tube, etc. o kēia mau mea hiki ke nānā ma o nā maka. Aia nā māka ahi maopopo loa ma ka ʻili o nā ʻenehana uila i pohō maoli. Hiki ke hoʻonā ʻia nā ʻano hemahema i ka hoʻololi ʻana i nā ʻāpana hewa me nā mea hou.

Pehea e ʻike ai i ka holo pono ʻole o ka papa PCB

Kuhi ʻia nā mea i hōʻino ʻia? ʻAʻole ia ka ʻāpana i haki

ʻOiaʻiʻo, ʻaʻole hiki ke ʻike ʻia nā hōʻino āpau o nā mea uila me ka maka ʻōlohelohe, e like me ke kūʻē ʻana i luna, capacitance, ʻelua a ʻekolu paha audion, i kekahi mau hihia, ʻaʻole hiki ke ʻike ʻia ka ʻino mai ka papa, pono e hoʻohana i ka ʻoihana. nā pono hana nānā no ka mālama ʻana, nānā pinepine ʻia me: Ke kuhi ka mika a mika capacitor paha ʻaʻole aia ka uila a i ʻole i kēia manawa o kahi mea uila i loko o ka pae maʻamau, hōʻike ia aia he pilikia me ka mea a i ʻole ka ʻāpana o mua. E kuapo i ka mea hana a nānā inā he maʻamau.

Pehea e ʻike ai i ka holo pono ʻole o ka papa PCB

He papa kaapuni me ka poino ʻole o ka helehelena a me ka ʻike ʻole i nā hewa

Inā haki ka mea, hiki ke ʻike ʻia e ka nānā maka ʻana a i ʻole ka ʻike mea hana. Eia nō naʻe, i kekahi manawa ke hāʻawi mākou i ka mea i ka papa PCB, e hālāwai mākou i ke kūlana i hiki ʻole ke ʻike ʻia ka pilikia, akā ʻaʻole hiki i ka papa kaapuni ke hana pono. ʻAʻole koho nā mea hoʻomaka he nui akā e kūkulu i kahi papa hou a kūʻai i hoʻokahi. I ka ʻoiaʻiʻo, i nā manawa he nui, nā ʻāpana i ke kaʻina hoʻonohonoho, ma muli o ka hoʻohui ʻana o nā mea like ʻole, aia paha he hana paʻa ʻole.

Pehea e ʻike ai i ka holo pono ʻole o ka papa PCB

Mahele kaapuni kaapuni

I kēia hihia, ʻaʻole hiki i ka mea kani ke kōkua, hiki iā ʻoe ke hoʻāʻo e hoʻoholo i ka laulā kūpono o ka hewa e like me ke au o kēia manawa a me ka uila, a hiki i ka mea hiki ke hōʻemi, hiki i nā ʻenekinia ʻike ke hoʻoholo koke i ka ʻāpana o ka hewa, akā ʻaʻole ia he 100% ʻike i kahi o nā mea kikoʻī i haki. ʻO ka hopena wale nō e hoʻāʻo a hoʻololi i ka mea i manaʻo ʻia a hiki i ka loaʻa ʻana. I ka makahiki i hala aku nei, a me kaʻu motherboard laptop, ka wai i ka manawa mālama haku e ʻike i ka hewa, a hoʻololi i nā mea ʻekolu i ke kaʻina hana o ka mālama ʻana, puʻuwai lako uila, diode, hāmeʻa hoʻoiho USB (laptop blue socket that, shutdown condition hiki recharge pono), ʻo ka hope loa me ka kānalua pani pani e ka hakahaka ʻike nalu, Ua hoʻoholo ʻia e lilo i kaapuni pōkole i kahi mea ma ka ʻaoʻao o ka ʻāpana Southbridge.

Pehea e ʻike ai i ka holo pono ʻole o ka papa PCB

Uea lele kaapuni

ʻO ka mea i luna ka pilikia o nā mea uila, ʻoiai, ʻoiai ʻo ka papa kaapuni PCB ma ke kahua o nā ʻāpana, a laila pono e ola ka papa kaapuni, ʻo kahi laʻana maʻalahi maʻalahi kahi ʻāpana piʻo make, ma muli o ke kaʻina hana, i ka Ke kaʻina hana o ka popopo PCB, aia paha kahi pilikia laina haʻihaʻi. I kēia hihia, inā ʻaʻole hiki iā ʻoe ke hoʻopiha i ka uea, hiki iā ʻoe ke hoʻohana wale i ka uea keleawe maikaʻi e hoʻonā i ka pilikia.
