Nā ʻāpana o ka PCB

1. Papahana

Papa Ua māhele ʻia ka papa i ka papa keleawe a me ka papa keleawe ʻole, ʻōlelo maʻamau i kekahi mau papa o ka papa e hōʻike i ka helu papa o ka papa keleawe.ʻO ka maʻamau, kau ʻia nā pad wili a me nā laina ma luna o ka uhi keleawe e hoʻopau ai i ka pili uila.E kau i ke ʻano wehewehe ʻano a i ʻole ke ʻano manaʻo ma ka uhi keleawe ʻole;Hoʻohana ʻia kekahi mau papa (e like me nā papa mechanical) no ka waiho ʻana i ka ʻike e pili ana i ka hana ʻana o ka papa a me ke ʻano o ka hui ʻana, e like me ka laina ana o ke kino o ka papa, ka hōʻailona ana, ka ʻikepili ʻikepili, ma o ka ʻike puka, nā ʻōlelo aʻoaʻo, etc.

2.Via

Ma o ka lua kekahi o nā mea nui o ka PCB multilayer.ʻO ke kumu kūʻai o ka lua wili he 30% a 40% o ke kumukūʻai o ka papa PCB.I ka pōkole, hiki ke kapa ʻia kēlā me kēia puka ma kahi PCB he puka puka.Mai ka manaʻo o ka hana, hiki ke hoʻokaʻawale ʻia ka puka i loko o ʻelua mau ʻāpana: hoʻohana ʻia kekahi e like me ka pilina uila ma waena o kēlā me kēia papa;Hoʻohana ʻia ka lua no ka hoʻoponopono ʻana a i ʻole ka ʻimi ʻana i nā mea hana.Ma nā ʻōlelo o ke kaʻina hana ʻenehana, ua māhele ʻia nā lua i ʻekolu mau ʻāpana, ʻo ia hoʻi, makapō ma.Kanu ia ma o a ma o.

3. Pad

Hoʻohana ʻia ka pad no ka hoʻopili ʻana i nā ʻāpana, ʻike i nā pili uila, hoʻoponopono i nā pine o nā ʻāpana a i ʻole no ke kaha kiʻi ʻana i nā uwea, nā laina hoʻāʻo, a me nā mea ʻē aʻe. paʻi pā.Pono e wili ʻia ka papa hoʻokomo o ka nila, ʻoiai ʻaʻole pono e wili ʻia ka papa hoʻopaʻa ili.Hoʻonohonoho ʻia ka pā wili o nā ʻano mea hoʻokomo i ka nila i loko o ka multi-layer, a ua hoʻonohonoho ʻia ka pā kuʻi o nā ʻano ʻano SMT ʻili i ka papa like me nā ʻāpana.

4. Track

ʻO ka uea kiʻiʻoniʻoni keleawe ka uea e holo ana ma PCB ma hope o ka hana ʻana o ka pā keleawe keleawe.Ua kapa ʻia ʻo ia he uea no ka pōkole.Hoʻohana maʻamau ia e ʻike i ka pilina ma waena o nā pads a he mea nui ia o ka PCB.ʻO ka waiwai nui o kahi uwea kona laulā, e hilinaʻi ana i ka nui o ka lawe ʻana i kēia manawa a me ka mānoanoa o ka pahu keleawe.

5. Hui Pūʻolo

ʻO ka pūʻolo ʻāpana ʻo ia hoʻi ka wili ʻana i ka ʻāpana maoli i ka papa kaapuni e alakaʻi i nā pine i waho.A laila lilo ka ʻeke paʻa i mea holoʻokoʻa.ʻO nā ʻano encapsulation maʻamau ʻo ia ka plug-in encapsulation a me ka encapsulation i kau ʻia ma luna.
