Nā ʻāpana o ka laina hana SMT:

Aia kahi laina hana SMT i nā ʻāpana pākahi e hana pū ana e hōʻoia i kahi kaʻina hana maʻalahi.Aia kēia mau mea nui:

1. SMT Machine: Ke kumu o kaSMT laina hanaʻo ia ke kuleana o ka mīkini no ke kau ʻana i nā mea uila ma ka PCB.ʻIke ʻia ʻo nā mīkini koho-a-wahi, hoʻohana kēia mau mīkini i nā lima robotic a me nā nozzles vacuum e koho i nā ʻāpana mai kahi mea hānai a kau pono iā lākou ma ka PCB.

2. Reflow umu: Ma hope o ka hui 'ana, ka PCB e hele i loko o ka reflow umu kahi o ka solder paʻi i hoʻohana 'ia no ka hoʻopaʻa 'ana i nā mea i loko o ka hehee a me ka solidifies, e hana i ka paa paa.ʻO ka umu reflow e hōʻoia i ka hana pono ʻana o nā hui solder a paʻa paʻa nā ʻāpana i ka PCB.

3. Paʻi paʻi paʻi: He mea koʻikoʻi ka hoʻohana pono ʻana o ka paʻi solder i ke kaʻina SMT.Hoʻohana ka mea paʻi paʻi solder i kahi stencil e hoʻopili ai i ka paʻi solder i ka PCB, e hōʻoia ana i ka alignment pololei me nā pad.

4. Pūnaehana Nānā: No ka mālamaʻana i nā kūlana maikaʻi, hoʻokomo ka laina hana holoʻokoʻa i kahi pūnaewele nānā.Nānā nā mīkini ʻike maka ʻokoʻa (AOI) i nā hemahema e like me ka nalo ʻana a i ʻole nā ​​mea i hoʻonohonoho pono ʻole ʻia, nā hemahema kūʻai aku, a me nā hemahema PCB.Hoʻohana pū ʻia nā ʻōnaehana nānā X-ray e ʻike i nā hemahema huna, e like me ka lawa ʻole o nā hui solder.
