Me ka wikiwiki o ka hoʻomohala ʻana i ka ʻoihana, e hoʻohana ʻia nā papa kaapuni ma nā kahua he nui.I ka wā e pili ana i nā papa kaapuni, pono mākou e haʻi i nā papa kaapuni soldered.He aha nā mākau o nā papa kaapuni kūʻai?E aʻo kākou pehea e kūʻai ai i ka PCB.
Ka mākaukau o ka hoʻoheheʻe ʻana i ka papa kaapuni 1:
ʻO ke kaʻina hana hoʻoheheʻe koho e pili ana i ka: flux spraying, kaapuni kaʻapuni preheating, immersion welding a me kauo kuʻihao.ʻO ke kaʻina hana hoʻoheheʻe flux I ka hoʻoheheʻe koho ʻana, he kuleana koʻikoʻi ke kaʻina hana hoʻopili flux.I ka hoʻomehana ʻana a me ka pau ʻana o ke kuʻi ʻana, pono e lawa ka hana o ka flux e pale aku i ka hoʻopili ʻana a me ka oxidation.Lawe ka X / y manipulator i ka papa kaapuni ma ka piko o ka nozzle flux, a hoʻoheheʻe ʻia ka flux i ke kūlana wili PCB.
Ka mākaukau o ka hoʻoheheʻe ʻana i ka papa kaapuni 2:
No ka koho ʻana i ka piko microwave ma hope o ke kaʻina hana hoʻoheheʻe hou ʻana, ʻo ka hoʻoheheʻe ʻana i ka flux ka mea nui loa, a ʻaʻole e hoʻohaumia ka ʻano lua micro hole i ka wahi ma waho o ka hui solder.ʻOi aku ka 2mm o ke anawaena kiko haʻahaʻa o ka ʻūhā wahi liʻiliʻi ma mua o 2mm, no laila ʻoi aku ka liʻiliʻi o ka orientation pololei o ka pulupulu i waiho ʻia ma ka papa kaapuni ma mua o 2mm ± 0.5mm e hōʻoia i ka uhi mau ʻana o ka flux ma ka ʻāpana e welded.
Ke akamai o ka hoʻolele ʻana i ka papa kaapuni 3:
ʻO ka ʻokoʻa ʻoi loa ma waena o lākou, ʻo ka ʻaoʻao haʻahaʻa o ka papa kaapuni ua hoʻopiha piha ʻia i ka solder wai i ka welding peak wave, ʻoiai ma ka welding koho, ʻo kekahi mau wahi kikoʻī e pili ana me ka nalu solder.No ka mea, ʻo ka papa kaapuni ponoʻī he ʻano hoʻoheheʻe wela maikaʻi ʻole, ʻaʻole ia e wela a hoʻoheheʻe i nā hui solder i nā ʻāpana pili a me nā wahi o ka papa kaapuni i ka wā wili.
Ma mua o ka wili ʻana, pono e hoʻopili ʻia ka flux ma mua.Ke hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana i ka nalu, hoʻopili wale ʻia ka flux i nā ʻāpana e welded ma ka ʻaoʻao haʻahaʻa o ka papa kaapuni, ma mua o ka PCB holoʻokoʻa.Eia kekahi, kūpono wale ka welding koho no ka hoʻopili ʻana i nā ʻāpana plug-in.He ala hou ka welding koho.Pono e ʻike pono i ke kaʻina hana wiliwili koho a me nā lako.
