Me ka hoʻomohala ʻana o ka miniaturization a me ka pololei o nā huahana uila, kaPCB hui hanaa ke piʻi aʻe nei ka nui o ka hui i hoʻohana ʻia e nā mea kanu hoʻoponopono uila, ʻoi aku ka liʻiliʻi a me ka liʻiliʻi o nā hui solder ma nā papa kaapuni, a ʻoi aku ka kiʻekiʻe o nā ukana mechanical, uila a me ka thermodynamic a lākou e lawe nei.Ke piʻi nei ke kaumaha a ke piʻi nei nā koi no ka paʻa.Eia nō naʻe, e ʻike ʻia ka pilikia o ka PCB hui solder hui i ke kaʻina hana maoli.Pono e nānā a ʻike i ke kumu e pale aku ai i ka hāʻule ʻole o ka hui solder mai ka hana hou ʻana.
No laila, i kēia lā, e hoʻolauna mākou iā ʻoe i nā kumu nui o ka hemahema o ka hui ʻana o ka hui ʻana o ka PCB solder joints.
ʻO nā kumu nui o ka hāʻule ʻole o ka hui ʻana o nā hui solder PCB:
1. Nā pine ʻāpana maikaʻi ʻole: plating, pollution, oxidation, coplanarity.
2. Poor PCB pads: plating, pollution, oxidation, warpage.
3.Solder quality defects: haku mele, haumia substandard, oxidation.
4. Nā hemahema maikaʻi ʻo Flux: haʻahaʻa haʻahaʻa, kiʻekiʻe corrosion, haʻahaʻa SIR.
5. Ke kaʻina hana ʻino ka mana hoʻohālikelike: hoʻolālā, hoʻokele, mea hana.
6. Nā hemahema mea kōkua ʻē aʻe: nā mea hoʻopili, mea hoʻomaʻemaʻe.
Nā ala e hoʻonui ai i ka paʻa o nā hui solder PCB:
ʻO ka hoʻokolohua kūpaʻa o nā hui solder PCB hui pū me ka hoʻokolohua kūpaʻa a me ka nānā ʻana.
Ma kekahi ʻaoʻao, ʻo kāna kumu e loiloi a ʻike i ka pae paʻa o nā ʻāpana hui hui PCB hui pū ʻia, a hāʻawi i nā ʻāpana no ka hoʻolālā kūpaʻa o ka mīkini holoʻokoʻa.
Ma kekahiʻaoʻao, ma ke kaʻina hana oHui PCBka hana ʻana, pono e hoʻomaikaʻi i ke kūpaʻa o nā hui solder.Pono kēia i ka nānā ʻana i ka huahana i hāʻule ʻole, e ʻike i ke ʻano o ka hāʻule ʻana, a me ka nānā ʻana i ke kumu hāʻule.ʻO ke kumu e hoʻoponopono a hoʻomaikaʻi i ke kaʻina hana hoʻolālā, nā ʻāpana hoʻonohonoho, ke kaʻina hana kuʻi, a me ka hoʻomaikaʻi ʻana i ka hopena o ka hana ʻana o ka hui PCB.ʻO ke ʻano hemahema o nā hui solder hui PCB ke kumu no ka wānana ʻana i kona ola pōʻaiapuni a hoʻokumu i kāna kumu makemakika.
I kahi huaʻōlelo, pono mākou e hoʻomaikaʻi i ka kūpaʻa o nā hui solder a hoʻomaikaʻi i ka hua o nā huahana.
Hana ʻia ʻo PCBFuture e hoʻolako i ke ʻano kiʻekiʻe a me ka hoʻokele waiwaiʻO ka lawelawe hui PCB hoʻokahii nā mea kūʻai honua āpau.No ka ʻike hou aku, e leka uila iāservice@pcbfuture.com.
