ʻO ka hana SMD kahi ʻano lawelawe hana uila, i kapa ʻia ʻo SMT.ʻO ka PCB kahi ʻano o nā ʻāpana substrate o PCBA, i kēia lā e kamaʻilio me ʻoe e pili ana i ke kuleana o ka paʻi paʻi ʻana o ka papa PCB.
ʻElua kuleana nui i paʻi ʻia i ka solder paste.
1. Hoʻopaʻa i nā mea uila
ʻO ka pāpaʻi solder e like me nā mea e like me ka toothpaste, kekahi mau mea pili, uila ma o kakoho a wahimīkini e kau ʻia i nā pads PCB ma luna, ma o ka hoʻopili ʻana o ka solder paste i nā ʻāpana liʻiliʻi liʻiliʻi a ʻaʻole e ʻae i ka PCB i loko o ke kaʻina hana holo moku e haʻalulu a alakaʻi i ka hāʻule.
2.Reflowumu, nā mea kūʻai aku i ka ulle wela wela
He mea nui ka Solder paste Z no hoʻoheheʻe houmīkini, no laila e piʻi ai nā mea uila i ka tin a me ka PCB pads i hoʻopaʻa ʻia, no ka mea, ʻo nā mea o ka solder paste he flux, tin pauka, tin pauka i loko o ka reflow soldering i loko ma hope o ka wela wela wela e hoʻoheheʻe ʻia e hana i kahi tin wai, no laila e ʻai nā ʻāpana i ka tin. , Ma hope o ka reflow soldering cooling area, wai ke kī i loko o kahi kūlana paʻa, i hoʻopaʻa ʻia nā ʻāpana a me nā pads e pāʻani i kahi hana conductive, e pāʻani i kahi hana o nā ʻāpana like ʻole. nā ʻāpana a me nā pad i kahi a me ka pāʻani ʻana i ka hana o nā ʻāpana like ʻole.
