ʻO ka spacing palekana uila e hilinaʻi nui ʻia i ke kiʻekiʻe o ka hale hana papa, ʻo ia ka 0.15mm maʻamau. ʻOiaʻiʻo, hiki ke kokoke loa. Inā ʻaʻole pili ke kaapuni i ka hōʻailona, ​​ʻoiai ʻaʻohe kaapuni pōkole a lawa ke ʻano o kēia manawa, pono ke au nui i ka uwea mānoanoa a me ka spacing.

1. Distance ma waena o nā uea

Pono e noʻonoʻo ʻia ka mamao ma waena o nā conductors e pili ana i ka mana hana o ka mea hana PCB. Manaʻo ʻia ʻo ka mamao ma waena o nā conductors ma kahi o 4mil. Eia nō naʻe, hiki i kekahi mau hale hana ke hana me 3/3mil ka laulā laina a me ka laina laina. Mai ka hiʻohiʻona o ka hana ʻana, ʻoiaʻiʻo, ʻoi aku ka maikaʻi ma lalo o nā kūlana. ʻOi aku ka maʻamau o ka 6mil maʻamau.

2.Spacing ma waena o ka pad a me ka uea

ʻO ka mamao ma waena o ka pad a me ka laina maʻamau ʻaʻole i emi iho ma mua o 4mil, a ʻoi aku ka nui o ka mamao ma waena o ka pad a me ka laina ke loaʻa kahi ākea, ʻoi aku ka maikaʻi. No ka mea e pono ai ka hoʻopaʻa ʻana i ka puka makani, ʻoi aku ka nui o ka puka makani ma mua o 2mil o ka pad. Inā lawa ʻole ka spacing, ʻaʻole ia e hoʻopōkole wale i ka papa laina, akā alakaʻi pū i ka ʻike keleawe o ka laina.

3. ʻO ka hakahaka ma waena o Pad a me Pad

ʻOi aku ka nui o ka mamao ma waena o ka pad a me ka pad ma mua o 6mil. He mea paʻakikī ke hana ʻana i kahi alahaka hoʻopaʻa solder me ka lawa ʻole o ka spacing pad, a he pōkole pōkole paha ka pad IC o nā ʻupena ʻokoʻa i ka wā e wili ai i ke alahaka weld hāmama. He liʻiliʻi ka mamao ma waena o ka pad network a me ka pad, a ʻaʻole maʻalahi ka wehe ʻana i nā ʻāpana i hoʻoponopono ʻia ma hope o ka hoʻopili piha ʻana o ka tin i ka welding.

4.Copper a me ke keleawe, uea, PAD spacing

ʻOi aku ka mamao ma waena o ka ʻili keleawe ola a me ka laina a me ka PAD ma mua o kēlā ma waena o nā mea papa laina ʻē aʻe, a ʻo ka mamao ma waena o ka ʻili keleawe a me ka laina a ʻoi aku ka PAD ma mua o 8mil e hoʻomaʻamaʻa i ka hana a me ka hana ʻana. No ka mea, ʻaʻole pono ka nui o ka ʻili keleawe e hana i ka waiwai nui, ʻaʻole nui ka liʻiliʻi a me ka liʻiliʻi liʻiliʻi. I mea e hoʻomaikaʻi ai i ka hoʻoulu ʻana o nā huahana, ʻo ka spacing ma waena o ka laina a me ka PAD mai ka ʻili keleawe e like me ka nui.

5.Spacing o ka uwea, PAD, keleawe a me ka lihi pā

ʻO ka maʻamau, ʻoi aku ka mamao ma waena o ka uwila, ka pad a me ka ʻili keleawe a me ka laina contour ma mua o 10mil, a ma lalo o 8mil e alakaʻi i ka ʻike keleawe ma ka lihi o ka pā ma hope o ka hana ʻana a me ka hoʻoheheʻe ʻana. Inā ʻo V-CUT ka lihi o ka pā, a laila ʻoi aku ka nui o ka mamao ma mua o 16mil. ʻAʻole ʻo ke keleawe wale nō ka uea a me ka PAD i hōʻike ʻia no ka maʻalahi, liʻiliʻi paha ka laina kokoke loa i ka lihi o ka pā, e hopena i nā pilikia o ka lawe ʻana i kēia manawa, ʻo PAD liʻiliʻi e pili ana i ka wiliwili, e hopena i ka maikaʻi ʻole.'
