uiga fausaga PCB
1. Ink solderresistant (Solderresistant/SolderMask): E le tatau ona 'ai vaega 'apa apamemea uma, o lea o le a lolomi le vaega e le'i 'aina i se vaega o mea (e masani lava epoxy resin) e vavae ese le 'apa kopa mai le 'ai apa i. aloese mai le le soldering.E i ai se ta'amilosaga pupuu i le va o laina apa.E tusa ai ma faiga eseese, ua vaevaeina i le suauu lanumeamata, suauu mumu ma le suauu lanumoana.
2. Dielectric layer (Dielectric): E faʻaaogaina e faʻamautu ai le faʻaogaina i le va o laina ma laulau, e masani ona taʻua o le substrate.
3. Fa'asagaga i luga ole laiga (SurtaceFinish): Talu ai e faigofie ona fa'asalaina le 'apamemea i totonu o le si'osi'omaga lautele, e le mafai ona tu'u (le lelei solderability), o lea o le a puipuia ai le 'apamemea e tu'u.O auala puipuia e aofia ai HASL, ENIG, Immersion Silver, Immersion TIn, ma organic solder preservative (OSP).O metotia taʻitasi e iai ona lava lelei ma faʻaletonu, faʻatasi e taʻua o togafitiga luga.

O matou laupapa PCBA ua mamanuina e faʻafetaui ai nei faʻatupulaia manaʻoga e ala i le tuʻuina atu o fofo maualuga e tuʻufaʻatasia ai le saoasaoa, faʻatinoga, ma le lelei o le teuina / fefaʻatauaʻiga.Pe o oe o se 'au'aunaga fa'akomepiuta ao, o se su'esu'ega tele fa'amaumauga po'o se fa'asalalauga fa'aagafesootai, o matou laupapa PCBA e lelei mo oe.
O le laupapa PCBA e faia i mea maualuga Fr-4 e faʻamautinoa ai le tumau ma le faʻamaoni.E 14 ona laulau, e maua ai le tele o avanoa mo vaega ma mafai ai ona tuʻufaʻatasia faʻasalalauga maualuga.Faatasi ai ma le mafiafia o le 1.6mm, ua ausia se paleni atoatoa i le va o le compactness ma le gaioiga.
Matou te malamalama i le taua o le faʻatulagaina saʻo, o le mea lea matou te mamanuina laupapa PCBA ma se laʻititi laʻititi / avanoa fafo o le 4 / 4mil.Ole mea lea e fa'amautinoa ai le felauaiga lelei o fa'ailo ma fa'aitiitia ai le fa'alavelave.i le pito maualalo.O le 0.25mm vili tele e fa'amautinoa ai le lautele o le fa'aogaina o feso'ota'iga, ma fa'afaigofie ai mo fa'asologa o fa'aputuga eseese.
Ina ia faʻamalieina le faʻatinoga ma puipuia le laupapa, matou te faʻaaogaina se faleʻie e ala i le faʻagasologa e taofia ai soʻo se susu poʻo mea leaga mai le ulufale atu i le PCB.Ole mea lea e fa'amautinoa ai le fa'atuatuaina sili atu ma le ola umi mo lau faiga fa'akomepiuta.
Ina ia maua le fesoʻotaʻiga sili atu ma le faʻafefeteina, o matou laupapa PCBA o loʻo faʻaalia ai le ENIG faʻamaeʻaina e aofia ai se mea manifinifi o auro i luga o le nickel.Ole mea lea e mafai ai ona maua se feso'ota'iga malosi ma fa'aleleia ai le fa'atinoga atoa o le laupapa.
O matou komipiuta ma laupapa PCBA pito sili ona lelei mo ou manaʻoga komepiuta.Faatasi ai ma ona foliga sili atu ma tulaga maualuga, e faʻamaonia ai le faʻatuatuaina o le faʻatinoga ma faʻamatalaga vave faʻamatalaga.Tumau i luma ole suiga faakomepiuta ma a tatou laupapa PCBA faʻaonaponei.
