Te Whakahaere Tika i te Pāmahana o te Oumu Whakahoki SMT hei Whakapai ake i te Kounga Whakarewa

He raruraru ki te whakahaere i te pāmahana o te ōumu reflow i te wā e hanga ana? Mā tēnei paerewa tautuhinga ka āwhina

I roto i te tukanga whakaputa SMT (Surface Mount Technology), ko te tika o te whakahaere pāmahana oumu reflow te mea e whakatau tika ana i te kounga o te whakarewa me te mahi a te hua hiko. Ahakoa he iti noa te peka ke, ka arahi pea ki ngā hapa pēnei i ngā hononga whakarewa makariri, ngā āputa, te kino rānei o ngā wāhanga.

Nā te wheako hanga PCBA me te tohungatanga hangarau whānui a RICH FULL JOY Electronics i whakawhanake te "Paerewa Tautuhinga Kōtaha Pāmahana o te Oumu Whakahou," e whakarato ana i tētahi aratohu pūtaiao, pūnaha, me te mahi mō te whakahaere pāmahana o te oumu whakahou SMT.

Tirohanga Whānui Paerewa

E pā ana tēnei paerewa ki ngā oumu whakahou katoa i roto i tā mātou awheawhe SMT, ā, ko ngā miihini SMT ngaio te kawenga mō te whakatakoto me te whakahaere i ngā kōtaha pāmahana hei whakarite i te whakahaere tika o te pāmahana i te wā whakarewa.

Te Whakarite i ngā Utauta

Hei ine tika me te whakatakoto i ngā kōtaha pāmahana, e hiahiatia ana ēnei taputapu: he whakamātautau PROFILE, he waea thermocouple, he papa PCB tūturu mō te ine, he karapu tiaki, me ngā whakaritenga mō te whakapiri honohono.

Te Whakatakoto Paerewa

1. Pūtake Tohutoro
Whakatakotoria ngā tawhā pēnei i te tere piki, te pāmahana whakamahana, me te pāmahana rerenga anō i runga i ngā āhuatanga o ngā momo whakapiri whakapiri (hei tauira, ngā whakapiri whakapiri kore-mata, he mea whakapiripiri).

2. Pūtake Ine
Me ine ngā kōtaha pāmahana ki runga i ngā papa PCB tūturu kia tika ai te whakaata i ngā pānga o ngā taiao whakaputa tuturu ki te whakawhiti wera.

3. Ngā Paerewa Whānui

·Te Tere Whakapiki: 1–4℃/s

·Rohe Whakamahana: 150–200℃, 60–120s

·Rohe Rere: ≥220℃ mō te 30–60 hēkona

·Te pāmahana tino pai: 235–250℃

·Te Tere Whakamatao:

4. Ngā Whakaritenga Motuhake
Whakarerekētia te kōtaha kia hihiri i runga i ngā urupare kounga hua, kia tino whai rānei i ngā whakaritenga a te kiritaki kua whakaritea.

5. Ngā Tawhā Whakaora I-Glue
Ko te pāmahana whakamaroke o te I-glue he 120℃, ko te wā whakamaroke i waenga i te 90–150 hēkona, ā, ko te mōrahi he 170℃.

Ngā Whakatūpato

1. Whakamātautau o ia rā
Me whakahaere he whakamātautau pāmahana katoa, ā, me tuhi i muri i te whakakānga, i te whakawhiti raina whakaputa rānei i ia rā.

2. Mana Whakahaere
Ko ngā kaihangarau SMT ngaio anake ka whai mana ki te whakarerekē i ngā tautuhinga kōtaha pāmahana.

3. Te Whakatutukitanga o ngā Whakatakotoranga a te Kaihoko
Whakatakotoria rawatia ngā tawhā tukanga kia rite ki ngā whakaritenga rerenga anō kua tohua e te kiritaki.

4. Te Tiaki Taputapu
Whakahaerehia ngā whakamātautau hau mō te pūnaha whakaputa hau o te oumu whakahurihuri i ia ono marama, kia mau ai te mahi. Kaua ngā rerekētanga pāmahana i waenga i ngā rohe e neke ake i te 70℃.

Whakamutunga

Mā te whakatinana i te "Paerewa Tautuhinga Kōtaha Pāmahana o te Oumu Whakahoki," ka whakarite a RICH FULL JOY Electronics i te whakarewatanga SMT kounga teitei, ka whakapai ake i te pono o te whakaputa me te mahi hua, ā, ka āwhina i ngā kiritaki ki te whakatere i te wā ki te mākete me te whiwhi painga whakataetae.
