ʻO ka mea hana hoʻoheheʻe reflow Chengyuan i loaʻa i ka hana lōʻihi a me ka hana ʻana ʻo nā kumu nui o ka reflow solder beads penei:
1. ʻO ka maikaʻi o ka hoʻoheheʻe ʻana ma muli o ka paʻi solder
ʻO ka mea metala i loko o ka paʻi solder, ke degere o ka oxidation o ka pauka metala, a me ka nui o ka pauka metala hiki ke hoʻopili i ka hana o nā pōpō solder.
2. He mana nui ko ke kila mesh
a.ʻO ka wehe ʻana o Stencil
ʻO ka hapa nui o nā hale hana e wehe i ka stencil e like me ka nui o ka pad, i maʻalahi ka paʻi ʻana i ka paʻi solder i ka ʻāpana solder mask a hana i nā pahu tin, no laila ʻoi aku ka maikaʻi o ka wehe ʻana o ka stencil i ka liʻiliʻi ma mua o ka nui maoli. .
b.Mānoanoa o ke kila mesh
ʻO ka stencil Baidu ma waena o 0.12 ~ 0.17mm, ʻoi aku ka mānoanoa e kumu ai ka "holo ʻana" o ka paʻi solder, e hopena i nā peʻa tin.
3. ʻO ke kaomi hoʻokomo o ka mīkini hoʻokomo
ʻO ka hoʻouka ʻana inā kiʻekiʻe loa ke kaomi, e kaomi ʻia ka paʻi solder i ka papa kūʻai kūʻai, no laila ʻaʻole nui loa ka piʻi ʻana.
