Hoʻoholo Hoʻokahi

ʻO nā hana o nā papa kaapuni i paʻi ʻia i nā mea uila e pili ana: hāʻawi i ke kākoʻo mechanical no ka hoʻoponopono ʻana a me ka hui ʻana no nā transistors, nā kaʻa i hoʻohui ʻia, nā resistors, capacitors, inductors a me nā mea ʻē aʻe.

Ke hoʻolālā mākou i ka papa PCB, loaʻa iā mākou kekahi mau lula: mua, e hoʻonohonoho i nā kūlana kumu nui e like me ke kaʻina hana hōʻailona, ​​a laila e hahai i ka "kaapuni mua paʻakikī a laila maʻalahi, ka leo ʻāpana mai ka nui a ka liʻiliʻi, ka hōʻailona ikaika a ka hoʻokaʻawale hōʻailona nāwaliwali, kiʻekiʻe a haʻahaʻa.E hoʻokaʻawale i nā hōʻailona, ​​e hoʻokaʻawale i nā hōʻailona analog a me nā kikohoʻe, e hoʻāʻo e hana i nā uwea i ka pōkole e like me ka hiki, a e hana i ka hoʻolālā e like me ke kūpono";pono e hoʻokaʻawale i ka "ʻāina hōʻailona" a me ka "ʻāina mana.

ʻO SMT kekahi o nā ʻāpana kumu o nā ʻāpana uila.Kapa ʻia ʻo ia ka ʻenehana mauna luna (a i ʻole ʻenehana mauna ʻili).Ua māhele ʻia i ʻaʻohe alakaʻi a i ʻole nā ​​alakaʻi pōkole.He hui kaapuni ia i hui ʻia e ka reflow soldering a i ʻole dip soldering.ʻO ka ʻenehana ka ʻenehana kaulana loa a me ke kaʻina hana i ka ʻoihana hui uila.

Hoʻohana like ʻole.ʻO nā mea waiwai nui no ka hana ʻana i nā papa kaapuni he lole aniani alkali-free, pepa fiber, a me ka resin epoxy.Papa puluniu aniani: lole fiberglass substrate, papa epoxy: ʻo ka mea hoʻopili he epoxy resin, FR4: substrate cotton fiber pepa.ʻO nā mea ʻekolu he mau papa fiberglass.
