O le a PCB faamalama

O uaea i luga o le PCB e ufiufi i le suauʻu, e mafai ona puipuia le taʻamilosaga puʻupuʻu ma le faʻaleagaina o le masini. The so-called window is to remove the paint layer on the wire, so that the wire can be exposed to tin.

Faʻafefea ona mamanuina PCB faʻamalama matala PCB tisaini faʻafefea ona seti faʻamalama faʻamalama tatalaina

E pei ona e vaaia i le ata o i luga, e auala atu i le faʻamalama. O le tatalaina faʻamalama PCB e le o se mea e masani ai, ma o le sili ona taʻatele atonu o le manatuaina o vaega. O outou na na faʻamavaeina se komepiuta ua latou iloa o le manatuaina o vaega e tasi le tamatamailima auro, pei ona faʻaalia i le ata oi lalo:

O le tamatamailima auro iinei o lona uiga tatala le faamalama, momono ma taalo.

O le tatalaina o faʻamalama e masani foʻi ona avea ma masani, o lona uiga, o le faʻaaogaina o le uamea e faʻateleina ai le mafiafia o le apamemea i le taimi mulimuli ane, e faigofie tele mo le taimi nei, e masani ai i le laupapa eletise ma le laupapa e faʻatonutonu ai afi.

Tatala Windows ma apamemea pupula i le PCB design

I le ata, matou te masani ona faʻamalieina tagata faʻatau manaʻoga mo le tatalaina o Windows ma faʻamalamalamaina ‘apamemea, ae e faigata tele ona fesoʻotaʻi ma latou aua o tagata faʻatau e tau leai se malamalama pe matou te le o malamalama lelei e uiga i lenei gaioiga. I la matou mamanu, masani ona fetaiaʻi tagata faʻatau manaʻomia e faʻaopopo se ufiufi ufiufi, ipu pito i le lotoifale apamemea pupula, ala i le pu matala teteʻe faʻamamaina, IC vevela magoto toe vaʻaia apamemea, gao apa apa ma isi. E tusa ai ma le tulaga moni, sei o tatou vaʻai atu i ni ata e faʻamatala ai.

1. Ufiufi puipuia

Afai e manaʻomia e le tagata faʻatau le faʻaopopoina o le ufiufi, o le mea e tatau ona matou faia o le faʻaopopo o le salemask ma le lautele o le 1mm. Matou manaʻomia le faʻamaonia ma le tagata faʻatau pe matou te manaʻomia e faʻaopopo mesh mesh. A faʻaopopo le Soldmask, e manaʻomia le tuʻu o le paʻu apamemea o le eleele i luga ole laiga i le vaega e faʻaopopo ai Soldmask. E tatau ona ufiufi le vaalele a le Soldmask, a leai o le a faʻaalia le substrate (FR4, ma isi). O isi fesoʻotaʻiga le faʻalelalolagi e le tatau ona sopoia le Soldmask. Faʻaopopo le Soldmask eria i le PCB aafiaga e faʻaali ai le samasama apamemea. O vaega e le faʻaopoopoina o le a ufiufi e le poloka poloka.

2, faʻamalama pu faʻamalama

I le mamanu, tatou masani ona faʻalogo i le atoa laupapa plug pu po o le lotoifale pupu pu, pe a faʻaopoopoina pu, matou faʻalogo i le plug pu igoa igoa o le kamupani e masani ona faʻafouina BGA, i se isi itu, e leai se BGA o uelo faʻamalama pu (la matou kamupani faʻamatalaga faʻapitoa). Faʻamatalaga lautele kamupani sili atu 12mil pu e tatau ona uelo faʻamalama pu.

3, IC faʻasalalauina vevela pad

I se tulaga lautele, i tua o le IC vevela dissipation pad faʻaopoopo faʻamalama faʻamalama (faʻaopopo le pito i tua soldmask sili atu nai lo pe tutusa ma le pad luga) ma le pu, ma i tua o le ufiufi ufiufi uʻamea, ina ia sili tuʻu le luga luga i totonu o le pu i tua o le paʻu kopa e sili atu i fafo.

4. O le gaoia o apa apa

I galu soldering, ina ia mafai ona foia le faafitauli o le fesoʻotaʻi apa mafua mai i le vavalalata vavalalata o pads, o le a tatou faʻaaogaina tadpole foliga o gao gao apa. Notice the copper skin with the same size as the solder should be added.

Faʻafefea ona iloa le apa luga PCB faʻamalama faʻamalama

O le matagaluega manaʻomia le tulia le 8-auala moligafua, pe a o le tele-auala moligafua tapunia pe a o le taimi nei ua faateleina, ina ia mautinoa ai le moni aʻafiaga, i le faʻalauteleina o le taimi nei laina i le taimi e tasi, ua faamoemoe e aveʻesea le uʻamea tetee vaega o le laina o loʻo i ai nei – lanumeamata lanumeamata vaega, pe a maeʻa ona faia le laupapa, e mafai ona e faʻaopopoina apa i le pito i luga, mafiafia le laina, mafai ona pasia sili atu nei.

O iʻuga moni e faʻapea:

O le auala faʻatinoina e faapea:

Naʻo le tusia o le laina i le ToPlayer (poʻo laloLayer faʻalagolago i luga o le a vaega o le preset laina o i ai) vaega, ona tusi lea o le laina e fetaui ma ia i le Topsolder (poʻo lalo solder) vaega.

PCB tisaini faʻafefea ona seti luga le faʻamalama faʻamalama

CB mamanu mafai ona setiina uaea uaea i TOP / BOTTOM SOLDER vaega.

TOP / BOTTOM SOLDER green oil layer: Faʻapipiina le TOP / BOTTOM layer ma le SOLDER green oil e puipuia ai le apa mai le ufiufi o le apamemea foil ma tausi faʻamama.

O le pupuni o faʻamalama suauʻu lanumeamata e mafai ona faʻatulagaina i luga o le pad, e ala i pu ma le eletise uaea o lenei vaega.

1. O le faaletonu, o le pad o le a tatalaina se faamalama i PCB design (OVERRIDE: 0.1016mm), o lona uiga, o le pad exposes apamemea foil, faʻalauteleina 0.1016mm, ma apa o le a faʻaopopoina i le taimi o galu soldering. Leai se tisaini suiga e fautuaina e faʻamautinoa ua maeʻa;

2. O le faaletonu, o le pu o le a tatalaina se faʻamalama i le PCB design (OVERRIDE: 0.1016mm), o lona uiga, o le pu o le a faʻaaliina apamemea foil, faʻalauteleina 0.1016mm, ma apa o le a faʻaopopoina i le taimi o soldering galu. Afai ole poloaʻiga e taofi le sau mai luga o le pu ma le kopa mai le sau i fafo, e tatau ona e siaki le filifiliga PENTING i le faʻaopopo uiga o le pu i le SOLDER MASK e tapunia le pu.

3, i se faʻaopopoga, lenei vaega mafai foi ona tutoʻatasi leai-eletise faʻapipiʻi, uʻamea teteʻe lanumeamata lanumeamata faʻafetaui avanoa faʻamalama. Afai o luga o le apamemea foil uaea, e faʻaaogaina e faʻaleleia atili ai le tulaga gafatia o le uaea, ma faʻaopopoina le faʻaopopoina o apa e faʻaopoopo pe a faʻamauina; Afai o loʻo i luga o le le-kopa foil uaea, e masani lava na fuafuaina mo tagavai ma faʻapitoa tagata vailiili lolomiga, ma le tagata screen lolomiga faʻaputuga mafai ona aveʻesea.
