I ka hihia o ka PCB hemahema, he aha nā ala a me nā mea hana e ʻike ai?

1. Common PCB kaapuni papa hāʻule ua nui ka noonoo ma luna o nā mea, e like me capacitors, resistors, inductors, diodes, triodes, kahua hopena transistors, etc. Ua akaka ka poino o na chips a me ke aniani oscillators, a ua oi intuitive e hookolokolo i ka hemahema. o keia mau mea Hiki ke nana ia me na maka.Loaʻa nā hōʻailona ahi i ʻike ʻia ma ka ʻili o nā mea uila me ka ʻike ʻino.Hiki ke hoʻopau ʻia ia mau hemahema ma ka hoʻololi pololei ʻana i nā ʻāpana pilikia me nā mea hou.

2. ʻAʻole hiki ke ʻike ʻia nā pōʻino a pau i nā mea uila me ka maka ʻole, a pono nā mea hana nānā ʻoihana no ka mālama ʻana.ʻO nā mea hana nānā maʻamau e hoʻohana ʻia: multimeter, capacitance meter, a me nā mea ʻē aʻe. Ke ʻike ʻia ʻaʻole ʻo ka volta a i ʻole ke au o kahi mea uila i loko o ka laulā maʻamau, ʻo ia hoʻi he pilikia me ka ʻāpana a i ʻole ka mea mua.E hoʻololi a nānā inā he mea maʻamau.

3. I kekahi manawa ke hoʻolako mākou i nā ʻāpana ma ka papa PCB, e hālāwai mākou i ke kūlana ʻaʻole hiki ke ʻike ʻia kahi pilikia, akā ʻaʻole hiki i ka papa kaapuni ke hana maʻamau.ʻO kaʻoiaʻiʻo, i ka wā e hālāwai ai i kēia ʻano kūlana, ʻo nā manawa he nui ma muli o ka hoʻonohonoho ʻana o nā ʻāpana like ʻole i ka wā o ka hoʻonohonoho ʻana i hiki ʻole ke paʻa ka hana;hiki iā ʻoe ke hoʻāʻo e hoʻoholo i ka nui o ka hewa e pili ana i ke ʻano o kēia manawa a me ka volta, a hoʻemi i ka wahi hewa; a laila e hoʻāʻo e hoʻololi i ka mea i manaʻo ʻia a ʻike ʻia ka ʻāpana pilikia.
