Lolomiina matagaluega Komiti Faatino matagaluega

A lomia laupapa matagaluega (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.PCBs can be single-sided (one copper layer), double-sided (two copper layers on both sides of one substrate layer), or multi-layer (outer and inner layers of copper, alternating with layers of substrate). Multi-layer PCBs allow for much higher component density, because circuit traces on the inner layers would otherwise take up surface space between components. The rise in popularity of multilayer PCBs with more than two, and especially with more than four, copper planes was concurrent with the adoption of surface mount technology.

laupapa matagaluega lua itu e fai si lavelave teisi nai lo PCB tasi itu. O nei laupapa o loʻo i ai naʻo le tasi le vaega o le mea faʻavae. Ae ui i lea, o loʻo i ai ni faʻaulu faʻafefe i itu taʻitasi. Latou te faʻaaogaina le kopa e fai ma mea faʻaulu. Tatou maulu loloto i totonu o le PCB itu lua e aoao atili ai!

Le Fauga ma Mea o le Itulua Itulau PCB

E mafai ona eseese mea PCB itu lua i luga o le faavae o le ituaiga galuega faatino. Ae ui i lea, o le mea autu e toetoe lava tutusa mo laupapa matagaluega uma. Ae ui i lea, o le fausaga o le PCB e eseese mai lea ituaiga i lea ituaiga.

Alafua: O le mea sili ona taua e faia i le fiberglass. E mafai ona e manatu o se auivi o le PCB.

Fa'aapa 'apa: E mafai ona fai iila po'o fa'ato'a ufiufi 'apamemea. O le mafuaaga lena e faalagolago i le ituaiga laupapa. O le iuga e tutusa lava pe e te faʻaaogaina foil poʻo le paʻu kopa. O laupapa ta'i lua itu o lo'o iai se 'apa kopa fa'aulu i itu uma e lua.

Solder Mask: O se vaega puipui ole polymer. O lea, e taofia ai le kopa mai le pupuu. E mafai ona e manatu e pei o le paʻu o le laupapa matagaluega. Solder PCB lua itu o se laasaga taua tele mo le tumau.

Silkscreen: o le vaega mulimuli o silkscreen. E ui lava e leai sona sao i le galuega a le laupapa matagaluega. E faʻaaogaina e le au gaosi e faʻaalia ai numera o vaega. E taua tele numera o vaega mo faʻamoemoega o suʻega. E le gata i lea, e mafai ona e lolomi logo a lau kamupani poʻo isi faʻamatalaga i le tulaga o tusitusiga.

Le itu lelei ma le le lelei o laupapa ta'i lua itu

O nisi nei o mea lelei ma le le lelei o laupapa fa'asalalau lolomi e lua itu:

Tulaga lelei o laupapa ta'i lua itu

Tulaga Maualuga: Fuafuaga ma le mamanuina o lenei PCB e manaʻomia se aofaiga lelei o galuega. E i'u ai i laupapa ta'avale sili ona lelei.

Lava Avanoa mo Vaega: E tele avanoa mo vaega. Aua o itu uma e lua o le layer e conductive.

Sili Filifiliga Filifiliga: O loʻo i ai faʻasalalauga faʻaulu i itu uma e lua. E mafai ona e fa'apipi'i vaega fa'aeletonika eseese i itu uma e lua. O lea e tele au filifiliga mamanu.

Sourcing ma goto i le taimi nei: A'o fa'aogaina e fai ma vaega pito i lalo, e mafai ona e fa'aogaina mo le goto ma su'esu'eina le taimi nei.

Fa'aoga: Ona o lona lelei, e mafai ona e fa'aogaina i le tele o talosaga.

Le lelei o laupapa Si'osi'omaga Fa'alua itu

Tau sili atu: Faʻafaigofie itu uma e lua, e sau i se tau maualuga teisi.

Manaomia Foafoa Tomai: E aofia ai se faiga e fai si faigata lua itu PCB mo lona faavaeina. O le mea lea, e te manaʻomia nisi inisinia tomai mo ana gaosiga.

Taimi Gaosiga: Taimi gaosiga e sili atu nai lo le PCB tasi itu ona o lona lavelave.

Fa'aogaina o laupapa Si'o Itu Lua

O lenei ituaiga o laupapa fa'asolo e fa'atuputeleina ai le tele o le ta'amilosaga. E sili atu foi ona fetuutuunai. Toeitiiti lava fa'aoga lua itu tu'ufa'atasi PCB gaosi i le tele o gadgets fa'aeletoroni. O lo'o i lalo nisi tulaga mata'ina fa'aoga o laupapa ta'i lua itu:

HVAC ma moli moli

Faiga fa'atonutonu auala

Laupapa ta'avale

Pulea fa'asolo ma le suiga o le Malosi

Pule faatonutonu ma sapalai eletise

E faʻataʻitaʻi ma mataʻituina meafaigaluega eseese

Lomitusi ma telefoni feaveai

Masini fa'atau.
