O manatu nei e masani ona amanaʻia pe a fuafuaina PCB vaega.

1. E faia Laupapa PCB foliga fetaui ma le masini atoa?

2. E talafeagai le va i le va o vaega? E i ai se tulaga poʻo se tulaga o feteʻenaʻiga?

3. E manaʻomia e PCB ona fausia? O faʻasao le auala gaioiga? O faʻaputuputu pu? Faʻafefea ona faʻatulaga ia pu faʻatulagaina?

4. Faʻafefea ona tuʻuina ma faʻamafanafana le mana module?

5. E talafeagai le sui o mea e manaʻomia e sui soʻo? E faigofie ona fetuʻunaʻi vaega e mafai ona fetuʻunaʻi?

6. O le va i le va o le vevela elemeni ma le vevela elemeni iloiloina?

7. Faʻafefea e le EMC faʻatinoina o le atoa laupapa? Faʻafefea mafai faʻalelei faʻaleleia atili ai le tetee-faʻalavelave gafatia?

Mo le faʻafitauli o le va i le va o vaega ma vaega, faʻavae i luga o le mamao manaʻoga o eseese afifi ma uiga o le Altium Designer lava ia, pe a fai o le faʻatapulaʻa e setiina e tulafono, o le nofoaga e sili ona faigata ma faigata ona ausia. O se laina ua tusia i luga o le masini vaega e faʻailoa mai ai le itu o fafo atu o vaega, e pei ona faʻaalia i le Ata 9-1, ina ia a o isi vaega o latalata atu, o le lata vavalalata ua iloa. E aoga tele lea mo tagata amata, ae mafai ai foʻi ona amata tagata e atiaʻe ni masaniga lelei o le mamanuina o le PCB.

Faʻafitauli luga PCB vaega faʻatulagaina

Ata 9-1 Masini ausilali fesoasoani

Faʻavae luga o luga o iloiloga ma auiliiliga, masani PCB faʻatulagaina tapulaʻa mataupu faʻavae mafai ona faʻavasega faʻapea.

Faʻavae mataupu faʻatulagaina

1. I lalo o tulaga masani, o vaega uma e tatau ona faʻatulagaina i luga o le tulaga e tasi o le PCB. Seʻi vagana o le pito i luga vaega ua mafiafia tele, o nisi o vaega ma le faʻatapulaʻa maualuga ma maualalo calorific aoga (e pei o malamala tetee, malamala capacitance, malamala IC, ma isi) mafai ona tuu i luga o le pito i lalo vaega.

2. On the premise of ensuring the electrical performance, the components should be placed on the grid and arranged parallel or vertically to each other in order to be neat and beautiful. I lalo o tulaga masani, vaega e le faʻatagaina e fesiliaʻi, o le faʻatulagaina o vaega e tatau ona puʻupuʻu, sao vaega ma galuega faatino vaega i le mamao e mafai ai vavae ese mai le tasi i le isi, e le foliga crossover.

3, atonu e maualuga voltage i le va o nisi vaega poʻo uaea, e tatau ona faʻateleina le latou mamao, ina ia le mafua ai faʻalavelave faʻafuaseʻi matagaluega ona o le faʻamatuʻuina, malepe, faʻatulagaina i le tele e mafai ai e faʻalogo ai i le faʻatulagaina o nei avanoa avanoa.

4. E tatau ona faʻatulaga mamao atu vaega e iai le voltage maualuga i nofoaga e le faigofie ona uia e le lima ile taimi e faʻatu ai le faʻamaʻa.

5, tu i le pito o le ipu vaega, tatau ona taumafai e faia lua ipu mafiafia mai le pito o le ipu.

6, vaega e tatau ona tutusa tufatufaina i luga o le laupapa atoa, ae le o lenei eria mafiafia, se isi eria avanoa, faʻaleleia le faʻatuatuaina o le oloa.

Mulimuli i le faʻavae mataupu faʻavae o faʻailoga

1. A maeʻa ona tuʻuina vaega faʻatulagaina, faʻatulaga le tulaga o vaega taʻitasi e faʻatino iunite taʻitasi e tusa ma le itu o le faʻailo, ma le vaega autu o taʻitasi faʻagaioiga matagaluega e avea ma ogatotonu ma faʻatautaia le faʻatulagaga faataamilo ia.

2. O le faʻatulagaina o vaega e tatau ona talafeagai mo faʻailo sologa, ina ia o le faʻailoga tausia le tutusa itu i le mamao e mafai ai. I le tele o tulaga, o le faʻailo tafe e faʻatulagaina mai le tauagavale i le taumatau pe mai luga i lalo, ma o vaega e fesoʻotaʻi tuusaʻo i le ulufale atu ma le faʻamutaina o mea e tatau ona tuʻu latalata i mea e faʻaulu ai ma mea e fesoʻotaʻi ai fesoʻotaʻiga poʻo fesoʻotaʻiga.

Puipuia le faʻalavelave a electromagnetic

Faʻafitauli luga PCB vaega faʻatulagaina

Ata 9-2 Faʻatulagaina o le inductor ma le inductor perpendicular i 90 tikeri

(1) Mo vaega ma malosi radiation malosiaga electromagnetic fanua ma vaega ma maualuga le malamalama i le electromagnetic induction, o le mamao i le va o latou tatau ona faʻateleina, poʻo se talita puipuia e tatau ona mafaufauina mo le puipuia.

(2) Try to avoid high and low voltage components mixed with each other and strong and weak signal components interlaced together.

(3) for components that will produce magnetic fields, such as transformers, loudspeakers, inductors, etc., attention should be paid to reducing the cutting of magnetic lines on printed wires when layout, and the magnetic field direction of adjacent components should be perpendicular to each other to reduce the coupling between each other. Ata 9-2 o loʻo faʻaalia ai le faʻatulagaina o inductors 90 ° perpendicular i le inductor.

(4) Puipuiga faʻalavelave faʻalavelave poʻo faigofie faʻalavelaveina modules, talita puipuia e tatau ona lelei faʻavaeina. Ata 9-3 o loʻo faʻaalia ai le fuafuaina o se ufiufi puipui.

Taofiofia o faʻalavelave faʻafuaseʻi

(1) E tatau ona tuʻu iai elemeni faʻatupuina le vevela i se tulaga e mafai ai ona faʻatamaʻia le vevela. Afai e tatau ai, e mafai ona seti se isi radiator poʻo se tamaʻi ili e tuʻu i lalo le vevela ma faʻaititia le aʻafiaga o vaega tuaoi, e pei ona faʻaalia i le Ata 9-4.

(2) Nisi maualuga-paoa poloka tuʻufaʻatasia, paoa maualuga paʻu, resistors, ma isi, tatau ona faʻatulagaina i nofoaga e faigofie ai le faʻamamaina o le vevela, ma vavaeʻese mai isi vaega i se vaʻaiga mamao.

Ata 9-3 Fuafuaina le ufiufi pupuni

Faʻafitauli luga PCB vaega faʻatulagaina

Ata 9-4 Faʻamama le vevela mo le faʻatulagaina

(3) O le elemene maʻaleʻale elemeni tatau ona latalata i le fuaina elemeni ma o ese mai le maualuga vevela eria, ina ia le aafia ai i isi vevela mana tutusa elemeni ma mafua ai le misoperation.

(4) Pe a tuʻu le elemeni i itu uma e lua, e masani ona le tuʻuina le elemeni i le pito i lalo.

Mataupu Faavae o le fetuunaiga vaega faʻatulagaina

O le faʻatulagaina o mea e mafai ona fetuʻunaʻi e pei o potentiometers, fesuiaʻiga capacitors, fetuʻunaʻiga coil inductance ma Laiti-fesuiaʻi tatau mafaufau i le fausaga manaoga o le atoa masini: afai o le masini fetuunai fafo, o lona tulaga tatau ona fetuʻunaʻi i le tulaga o le fetuʻunaʻi faʻamau i luga o le vaega faʻasolo; I le tulaga o totonu-masini fetuʻunaʻiga, e tatau ona tuu i luga o le PCB i le mea e faigofie ona fetuʻunaʻi.
