Ngā Kaupapa Matua o te Whakahaere Tukanga i roto i te Tukanga Tānga Whakapiri Solder SMT

I. Te Mana Whakamahinga o te Whakapiri Konukōre

• Whāia te mātāpono tuatahi-ki-roto-ki-waho. Whai muri i te taenga mai o te whakapiri whakapiri ki te wheketere, whakapiri tonu i te "Tapanga Whakahaere Whakamahinga Whakapiri Whakapai" ka rongoa ki roto i te pouaka whakamātao i te 2 - 8°C. Whakamahia te whakapiri whakapiri kia rite ki te rā paunga i roto i te raupapa. Tangohia te whakapiri whakapiri me te tau iti ake i te tuatahi. Tukua te whakapiri whakapiri kia mahana i roto i te pouaka ārai makuku mō te neke atu i te 4 hāora i mua i te whakamahinga. Whakakīia te puka whakahaere whakapiri whakapiri ina tangohia te whakapiri whakapiri.

II. Te Whakahaere Pāmahana o te Pouaka Whakamātao

• Me pupuri te pāmahana o te pouaka whakamātao ki te 2 - 8°C. Mēnā he rerekē te pāmahana, whakatikahia te āhuatanga, ka whakakīia te "Pūka Rekoata Whakahaere i ngā Āhuatanga Rerekē o te Pāmahana Pouaka Whakamātao".

III. Mana Tāpiri Whakapiri Konukōre

1. Tautuhia te maha o ngā wā tānga mīhini i runga i te nui o te whakapiri honohono i whakamahia mō tētahi panera kotahi o tētahi mea motuhake.IC tauira. Tāpirihia te whakapiri honohono ina hiahiatia, whakaūhia te nui o te honohono, ka whakakīia te "Puka Tirotiro me te Tāpiri i te Whakapiri Hono".
2. Kia ma te mata whakaranu kirihou mō te tāpiri i te whakapiri konukōre.
3. Whakamahia te whakapiri whakarewa kua whakatuwheratia i roto i ngā hāora 24. Ka taea te penapena i te whakapiri whakarewa kāore anō kia whakatuwheratia ki roto i te whare mō te iti rawa o te kotahi marama. Maka atu mēnā ka roa ake te wā rokiroki.

IV. Mana Tātuhi

1. Te Horoi i te Tānga Hanga: Horoia te tānga hanga i mua i te haere ki te ipurangi, i ia 6 hāora i te wā e whakamahia ana, me te wā e mutu ai te raina whakaputa mō te 30 meneti.
2. Tirotiro Horoi Tānga: Tirohia te tānga i muri i te horoinga kia kore ai he toenga whakapiri whakarewa i runga i ngā pakitara o te kōhao, ā, kāore hoki he kino ki te tānga.
3. Whakahaere Kukū: Inehia te kukū ki te mita kukū i muri i ia horoinga ina haere koe ki te ipurangi, ina hoki koe ki waho o te ipurangi. Me ≤ - 0.21mm, ≥ 32N/cm rānei te kukū.
4. Tātuhi SCRMana Whakahaere: Paraia te tauira ina tae ki te 150,000 whakamahinga (tatauhia mā te PCS/whakamahinga) kua pakaru rānei.
5. Te Tukanga Horoi i ngā Tānga: Whakahaerehia te urunga me te putanga o ngā tānga mā te whakamahi i te pūnaha MES.

V. Te Whakatikatika i te Tūnga PCB

VI. Mana Whakahaere Squeegee

1. Whakahaere i te squeegee: Whakamahia te pūnaha MES hei whakahaere i ngā mahi katoa ina hono te squeegee ki te ipurangi, ki te tuimotu rānei.
2. Te Horoi me te Whakaritenga: Horoia te squeegee i muri i tana whakaweto. Tirohia mēnā he kino i muri i te horoinga.
3. Whakahaere Para: Whakakapia te squeegee ki tētahi mea hou i muri i te 150,000 whakamahinga (inā rānei kua pakaru).

VII. Te Horoi PCB

VIII. Mana Tānga Whakapiri Konukōrero

1. Ka kitea aunoatia e te mīhini SPI (te matotoru, te horahanga, te rōrahi, te ara iahiko poto, te ngaro o te tānga, te āputaputa) ka tuhia hoki ia papa.
2. Mena kāore e taea e te SPI te peRFMēnā ka kitea te mea nā te kore o te mīhini SPI, nā ētahi atu take rerekē rānei, me tirotiro matapōkeretia e ngā kaimahi. Tirohia ā-kanohi te tānga whakapiri whakapiri (kāore he ara iahiko poto, kāore he tānga ngaro, kāore he āputaputa, he āputaputa rānei
3. Te Matotoru me te Mana Whakahaere Rōrahi o te Whakapiri Konukō:
   • Awhe Tohutoro Mana Matotoru o te Whakapiri Konukō: (Ko te mīhini SPI te nuinga o te whakahaere mā te rōrahi, ā, ko te matotoru hei tohutoro āwhina.)
     • a. Mō te 0.5 mm Pitch CSP / Micro BGA: T - 0.005mm ~ T + 0.055mm
     • b. Mō te 0.5 mm te teitei o te QFP / QFN: T - 0.005mm ~ T + 0.055mm
     • c. Mō te 0.8 - 1.0 mm Pitch BGA/CSP: T - 0.005mm ~ T + 0.065mm
     • d. Mō te Maramara Noa (RLC me ētahi atu): T - 0.005mm ~ T + 0.085mm (Tuhipoka: T = te matotoru o te tauira)
   • Mana Whakahaere Rōrahi Whakapiri Konukō (mō te ine mīhini SPI):
     • a. Mō te 0.5 mm Pitch CSP / Micro BGA: 0.0016387 ~ 0.008194mm³
     • b. Mō te CSP/Micro BGA 0.65 - 0.8mm: 0.0065548 ~ 0.029497mm³
     • c. Mō te CSP/PBGA/Micro BGA 1.0mm: 0.0163871 ~ 0.081935mm³
     • d. Tirohia te tāpiritanga e whai ake nei mō te whakahaere oro o ētahi atu wāhanga.

• • Ina whakamahia te SPI hei tirotiro i te kounga o te tānga whakapiri honohono, me tirotiro, me tuhi hoki e te kaiwhakahaere te uara CPK me te matotoru toharite i ia 2 hāora.
