No ke ahahoʻoheheʻe hou ʻanakapa ʻia ʻo "reflow"?Ka reflow o reflow soldering 'o ia hoʻi ma hope o kapaʻi kūʻaihiki i ka helu heheʻe o ka paʻi solder, ma lalo o ka hana o ka ʻili o ka ʻili o ka ipu wai a me ka flux, kahe hou ka ipu wai i nā pine ʻāpana e hana i nā hui solder, e ʻae ana i ke kaʻina ʻo kahi kaʻina hana e hoʻopaʻa ʻia ai nā papa a me nā ʻāpana. ʻO ke kaʻina hana "reflow".
1. Ke komo ka PCB papa i ka reflow wela wahi, evaporate ka solvent a me ke kinoea i loko o ka solder paste.I ka manawa like, hoʻomaʻemaʻe ka paʻi solder i nā pad, nā hopena a me nā pine, a palupalu a hāʻule ka paʻi solder., E uhi ana i ka pad, e hoʻokaʻawale i ka pad a me nā pine o nā mea mai ka oxygen.
2. Ke komo ka PCB kaapuni i ka reflow soldering insulation wahi, ka PCB a me na mea i piha preheated e pale aku i ka PCB mai hikiwawe komo i ka wela wela wahi o ka welding a me ka poino i ka PCB a me na mea.
3. Ke komo ka PCB i ka reflow soldering area, piʻi koke ka wela a hiki i ka mea hoʻoheheʻe solder i kahi mokuʻāina hoʻoheheʻe ʻia, a pulu ka wai solder a hoʻopuehu i nā pads, nā ʻāpana ʻāpana a me nā pine o ka PCB, a hoʻoheheʻe ka ipu wai a hui pū. e hana i nā hui solder.
4. Ke komo nei ka PCB i ka reflow cooling zone, a ua hoʻokuʻu hou ʻia ka ipu wai e hoʻopaʻa i nā hono solder e ka ea anuanu o ka reflow soldering;i keia manawa, ua pau ka reflow soldering.
ʻO ke kaʻina hana holoʻokoʻa o ka reflow soldering ʻaʻole hiki ke hoʻokaʻawale ʻia mai ka ea wela i ka umu reflow.ʻO ka hoʻoheheʻe hou ʻana e hilinaʻi i ka hana o ke kahe ʻana o ka ea wela ma nā ʻāpana solder.Ke hele nei ke kahe e like me ka jelly i ka hopena kino ma lalo o kahi kahe ea wela kiʻekiʻe e hoʻokō ai i ka soldering SMD;reflow soldering ""Reflow" no ka mea, kaʻapuni ke kinoea i hope a i waho i loko o ka mīkini wiliwili e hoʻoulu i ka wela kiʻekiʻe e hoʻokō ai i ke kumu o ka kuʻi ʻana, no laila ua kapa ʻia ʻo reflow soldering.
