ʻO ka mīkini hoʻāʻo solder paste, ʻike ʻia hoʻi ʻo ka mīkini paʻi stencil a i ʻole ka mīkini solder paste inspection (SPI), kahi mea hana e hoʻāʻo ai i ka maikaʻi a me ka pololei o ka waiho ʻana o ka solder paste ma nā papa kaapuni paʻi (PCB) i ka wā o ka hana ʻana.
Hana kēia mau mīkini i kēia mau hana:
Ka nānā ʻana i ka nui o ka solder paste: Ke ana ka mīkini a nānā i ka nui o ka solder paste i waiho ʻia ma ka PCB.E hōʻoia kēia e hoʻohana ʻia ka nui kūpono o ka solder paste no ke kūʻai pono ʻana a hoʻopau i nā pilikia e like me ka solder balling a i ʻole ka lawa ʻole o ka uhi solder.
Ka hōʻoia o ka solder paste alignment: Hōʻoia ka mīkini i ka alignment o ka solder paste e pili ana i nā pā PCB.Nānā ia no kekahi misalignment a offset paha, e hōʻoia ana e kau pololei ʻia ka paʻi solder ma nā wahi i manaʻo ʻia.
Ka ʻike ʻana i nā hemahema: ʻIke ʻia ka mīkini hoʻāʻo solder paste i nā hemahema e like me ka hamo ʻana, ka hoʻopili ʻana, a i ʻole nā waihona solder misshapen.Hiki iā ia ke ʻike i nā pilikia e like me ka nui a i ʻole ka lawa ʻole o ka solder paste, ka waiho ʻole ʻana, a i ʻole ke paʻi ʻia ʻana o nā kumu kūʻai.
Ana o ke kiʻekiʻe o ka solder paste: Ana ka mīkini i ke kiʻekiʻe a i ʻole ka mānoanoa o nā waihona paʻi solder.Kōkua kēia i ka hoʻopaʻa ʻana i ka hoʻokumu ʻana o ka hui solder a pale i nā pilikia e like me ka tombstones a i ʻole nā huʻu hui solder.
Ka helu helu helu a me ka hōʻike ʻana: Hāʻawi pinepine nā mīkini hoʻāʻo solder paste i ka nānā ʻana a me ka hōʻike ʻana i nā hiʻohiʻona, e ʻae ana i nā mea hana e nānā a nānā i ka maikaʻi o ka waiho ʻana o ka solder paste i ka manawa.Kōkua kēia ʻikepili i ka hoʻomaikaʻi ʻana i ke kaʻina hana a kōkua i ka hoʻokō ʻana i nā kūlana maikaʻi.
Ma ke ʻano holoʻokoʻa, kōkua nā mīkini hoʻāʻo solder paste e hoʻomaikaʻi i ka hilinaʻi a me ka maikaʻi o ke kūʻai ʻana i ka hana PCB ma o ka hōʻoia ʻana i ka noi solder paste pololei a ʻike i nā hemahema ma mua o ka hana hou ʻana, e like me ka reflow soldering a i ʻole soldering nalu.He mea koʻikoʻi kēia mau mīkini i ka hana ʻana i nā hua a me ka hōʻemi ʻana i ka manawa o nā pilikia e pili ana i ka solder i nā hui uila.
