He aha ka reflow soldering?
ʻO ka hoʻoheheʻe hou ʻana e pili ana i ka hoʻohana ʻana i ka solder paste e hoʻopili ai i hoʻokahi a ʻoi aku paha nā mea uila i nā pad contact, a e hoʻoheheʻe i ka solder ma o ka hoʻomehana hoʻomalu ʻia e hoʻokō i ka hoʻopaʻa paʻa mau.Hiki ke hoʻohana ʻia nā ʻano hana hoʻomehana like ʻole e like me nā umu reflow, nā kukui hoʻomehana infrared, a i ʻole nā pū wela.no ka wiliwili ana.ʻO Reflow soldering ka mea maʻamau i hoʻohana ʻia no ka hoʻopaʻa ʻana i nā ʻāpana uila i nā papa kaapuni i paʻi ʻia e ka ʻenehana mauna luna.ʻO kekahi ala ʻē aʻe ʻo ka hoʻopili ʻana i nā mea uila ma o ka hoʻokomo ʻana i loko o ka puka.
ʻO ka hana kaʻa o reflow soldering?
He kiʻekiʻe loa ka mahana hana o ka reflow soldering, a ʻo ka hana nui o ka kaʻa ka hoʻokele ʻana i ka huila makani e hoʻopau i ka wela.
ʻEhia mau ʻāpana wela o ka hoʻoheheʻe hou ʻana?He aha ka mahana?ʻO ka ʻāpana hea ke kī?
Hoʻokaʻawale ʻia ʻo Chengyuan reflow soldering i ʻehā mau ʻāpana wela e like me ka hana o ka ʻāpana wela: ka wela wela, ka ʻāpana wela mau, ka ʻāpana kūʻai, a me ka ʻāpana anuanu.
Common reflow soldering i loko o ka makeke komo ewalu wela āpana reflow soldering, eono wela āpana reflow soldering, umi wela āpana reflow soldering, umikumamalua wela wahi reflow soldering, umikumamaha wela wahi reflow soldering, etc.Eia nō naʻe, ʻewalu wale nō ka hoʻoheheʻe ʻana o ka wela wela i ka mākeke ʻoihana.No ka hoʻoheheʻe hou ʻana i nā ʻāpana wela ʻewalu, ʻo ka hoʻonohonoho wela o kēlā me kēia wahi wela e pili nui ana i ka paʻi solder a me ka huahana e kūʻai ʻia.He koʻikoʻi ka hana o kēlā me kēia wahi.Ma ka ʻōlelo maʻamau, hoʻohana ʻia nā ʻāpana mua a me ka lua ma ke ʻano he preheating zones, a ʻo ke kolu a me ka ʻehā ʻelima nā ʻāpana preheating.ʻO ka ʻāpana wela mau, 678 e like me ka welding zone (ʻo ka mea nui loa kēia mau ʻāpana ʻekolu), hiki ke hoʻohana ʻia nā ʻāpana 8 e like me ka ʻāpana kōkua o ka ʻāpana hoʻoluʻu, a me ka ʻāpana hoʻoluʻu, ʻo ia ke kumu, pono e ʻōlelo ʻia he kakaikahi. ʻO nā ʻāpana ke kī , Pono e hoʻomaikaʻi ʻia ka maikaʻi o ka huahana, ʻo ia ka wahi ke kī!
1. Wahi hoʻomehana mua
Ua wela ka wahi preheating i 175 degere, a ʻo ka lōʻihi e pili ana i 100S.Hiki ke ʻike ʻia mai kēia e hiki ke loaʻa ka helu wela o ka preheating zone (no ka mea, ua hoʻohana kēia mea ʻike i ka hoʻāʻo pūnaewele, ʻaʻole ia i komo i ka ʻāpana preheating no kahi manawa mai 0 a 46S. , lōʻihi 146-46=100S, no ka mea, he 26 degere 175–26=149 degere ka wela o ka wela o loko 149 degere/100S=1.49 degere/S)
2. Wahi wela mau
ʻO ka wela kiʻekiʻe loa ma ka wahi wela mau ma kahi o 200 degere, ʻo ka lōʻihi he 80 kekona, a ʻo ka ʻokoʻa ma waena o ka wela kiʻekiʻe a me ka mahana haʻahaʻa he 25 degere.
3. ʻĀpana hoʻihoʻi hou
ʻO ka mahana kiʻekiʻe loa ma ka reflow zone he 245 degere, ka haʻahaʻa haʻahaʻa he 200 degere, a ʻo ka manawa e hiki ai i ka piko ma kahi o 35 / S;ka hoʻomehana ʻana i ka ʻāpana reflow
Ka helu: 45 degere/35S=1.3 degere/S Wahi a (pehea e hoʻonohonoho pono ai i ka pihi wela), hiki ke ʻike ʻia he lōʻihi loa ka manawa e hiki ai kēia piʻi wela i ka waiwai kiʻekiʻe.ʻO ka manawa reflow holoʻokoʻa ma kahi o 60S
4. Wahi hooluolu
ʻO ka manawa i loko o ka ʻāpana hoʻomaha ma kahi o 100S, a hāʻule ka mahana mai 245 degere a ma kahi o 45 degere.ʻO ka māmā hoʻomaha: 245 degere—45 degere=200 degere/100S=2 degere/S
