Faatauva PCB Faumea

SMT o le fa'apu'upu'u mo Fa'agata Fa'atekonolosi Fa'atekonolosi, le sili ona ta'uta'ua Tekonolosi ma fa'agasologa i totonu o pisinisi fa'apotopotoga fa'aeletoroni. Fa'aeletonika Fa'atekonolosi Fa'atekonolosi Mauga (SMT) e ta'ua o le Mauga Fa'asaga po'o le Fa'atekonolosi Mauga. O se ituaiga o tekinolosi faʻapotopotoga faʻapipiʻi e faʻapipiʻi le taʻitaʻia poʻo le puʻupuʻu taʻitaʻi vaega faʻapotopotoga faʻapotopotoga (SMC / SMD i Saina) i luga o le Laupapa Lolomi Faʻatonu (PCB) poʻo isi mea faʻapipiʻi, ona faʻapipiʻi lea ma faʻapipiʻi e ala i le faʻafefeteina o le uelo poʻo lofu uelo.

I se tulaga lautele, o oloa faaeletonika tatou te faaaogaina e faia i le PCB faaopoopo capacitors eseese, tetee ma isi vaega faaeletonika e tusa ai ma le ata o le matagaluega, o lea o ituaiga uma o meafaigaluega eletise e manaomia eseese SMT masini gaosi tekinolosi e faagaoioia.

SMT elemene faiga faavae e aofia ai: lomitusi screen (po o le tuʻuina atu), faʻapipiʻi (faʻamalolo), faʻafefeteina faʻafefe, faʻamamā, suʻega, toe faʻaleleia.

1. Lomiga mata: O le galuega o le lomitusi screen o le liaʻi le paʻu solder poʻo faʻapipiʻi faʻapipiʻi i luga o le solder pad a le PCB e saunia ai mo le faʻapipiʻiina o vaega. O meafaigaluega e faʻaaogaina o le masini lomitusi mata (screen printing machine), o loʻo i le pito i luma ole laina ole SMT.

2. Kelu spraying: E ​​pa'ū kelu i le tulaga tumau o le laupapa PCB, ma o lona galuega autu o le faaleleia vaega i le laupapa PCB. O meafaigaluega e faʻaaogaina o le masini tuʻufaʻatasia, o loʻo i le pito i luma ole laina ole SMT poʻo tua o mea suʻega.

3. Mauga: O lana galuega o le faʻapipiʻi saʻo vaega faʻapotopotoga luga i le tulaga tumau o PCB. O meafaigaluega faʻaaogaina o le SMT faʻapipiʻi masini, o loʻo i tua o le masini lomitusi mata i le laina gaosiga SMT.

4. Fa'amālōlōina: O lana galuega o le fa'afefeteina o le SMT fa'apipi'i ina ia mafai ona pipii fa'atasi vaega fa'apotopotoga i luga ma le laupapa PCB. O meafaigaluega faʻaaogaina o le ogaumu faʻamalolo, o loʻo i tua o le laina SMT SMT.

5. Reflow uelo: o le galuega tauave o le reflow uelo o le liusuavai o le faapipii solder, ina ia i luga o le faapotopotoga vaega ma PCB laupapa mau pipii faatasi. O meafaigaluega e faʻaaogaina o le ogaumu faʻafefe, o loʻo i totonu o le laina gaosiga o le SMT i tua o le masini faʻapipiʻi SMT.

6. Fa'amamāina: O le galuega o le aveese lea o le toega uelo e pei o le flux i luga o le PCB fa'apipi'i e afaina i le tino o le tagata. O meafaigaluega e faʻaaogaina o le masini faʻamamaina, e le mafai ona faʻamautu le tulaga, e mafai ona i luga ole laiga, pe leai foi ile initaneti.

7. Suʻesuʻega: E faʻaaogaina e iloa ai le lelei o le uʻamea ma le faʻapotopotoga lelei o le PCB faʻapipiʻi. O meafaigaluega e faʻaaogaina e aofia ai tioata faʻalautele, microscope, mea faʻataʻitaʻiga i luga ole laiga (ICT), mea faʻataʻitaʻiga o nila lele, suʻega faʻapitoa (AOI), faiga faʻataʻitaʻiga X-ray, mea faigaluega suʻega, ma isi. vaega o le laina gaosiga e tusa ai ma manaoga o le asiasiga.

8.Repair: e faʻaaogaina e toe faʻaleleia ai le PCB ua iloa ma faʻaletonu. O meafaigaluega e faʻaaogaina o uʻamea faʻapipiʻi, fale faigaluega toe faʻaleleia, ma isi. O le faʻatulagaina o soʻo se mea i le laina gaosiga.
