Faatasi ai ma le alualu i luma o faaeletonika tekonolosi, le faigata o le PCB (lolomi laupapa matagaluega), o le lautele o le tusi talosaga o loʻo i ai se vave atinaʻe. Designers engaged in HF PCB must have relevant basic theoretical knowledge and rich experience in THE manufacture of HF PCB. I se isi faaupuga, uma ata faʻataʻitaʻi ma PCB mamanu tatau ona mafaufauina mai le maualuga-taimi faigaluega siʻosiʻomaga, ina ia mafai ai ona mamanuina se sili lelei PCB.

Lenei pepa, o le PCB uaea, uelo ipu ma faʻaogaina le mamanu metotia o le kopa, muamua o mea uma, i luga o le faʻavae o PCB uaea, faʻamau, o le uaea manaʻomia ma le eleele uaea manaʻoga i le tulaga o le pepa faʻalauiloaina le mamanu o le PCB uaea, lona lua mai le faʻamau pad ma aperture, PCB pad lapoʻa ma foliga o le ata i le ata o le faʻavae, o manaʻoga o PCB gaosiga pads o loʻo faʻalauiloaina le mamanu o le PCB solder, I le iuga, mai le PCB apamemea ufiufi tomai ma tulaga faʻalauiloaina le PCB apamemea ufiufi mamanu, faʻapitoa mulimuli xiaobian ia malamalama.

PCB uaea mamanu

O le telefoni o le manaʻoga lautele lea o le hf PCB design e faʻavae i luga o le faʻatulagaina talafeagai. Cabling aofia otometi cabling ma tusi lesona cabling. E masani lava, tusa lava pe fia ni laina faʻailo o loʻo i ai, e tatau ona faʻataʻitaʻi muamua le faʻaogaina o laina uila mo nei laina faʻailo. Ina ua maeʻa uaea, o le uaea o nei laina faʻailo tatau ona siaki ma le faʻaeteete ma faʻamaeʻaina pe a pasia le siaki, ona tatau ai lea ona otometi uaea isi uaea. O lona uiga, o le tuʻufaʻatasia o le tusi lesona ma otometi faʻaaogaina uaea e faʻaatoa ai PCB uaea.

O itu ia e tatau ona totogia faʻapitoa vaʻaia i le taimi o le faʻaaogaina o le hf PCB.

1. Le itu o uaea

O le uaea o le matagaluega e sili ona lelei e faʻaogaina se laina saʻo atoa e tusa ai ma le faʻatonuga o le faʻailo, ma le 45 ° laina motusia poʻo piʻo piʻo mafai ona faʻaaogaina e faʻamaeʻa ai le liliu itu, ina ia faʻaititia ai le emission fafo ma soʻotaga soʻofaʻatasi o maualuga -faʻailoilo masani. O le uaea o uaea maualuga faailo taimi tatau tatau ona puʻupuʻu mafai. E tusa ai ma le galulue taimi o le taʻamilosaga, o le umi o le laina faʻailoaina tatau tatau talafeagai, ina ia faʻaititia ai le tufatufaina aiai ma faʻaititia le leiloa o le faʻailoga. A o faia faʻalua panels, e sili ona lelei le auala o le lua sosoʻo sosoʻo faʻasolosolo, faʻasoʻo pe piʻo e faʻafesoʻotaʻi le tasi i le isi. Aloʻese mai le tutusa i le tasi ma le isi, lea e faʻaititia ai faʻalavelave faʻatasi ma fesoʻotaʻiga faʻatasi.

Laina maualuga laina laina ma maualalo laina laina faʻailo tatau tatau ona vavaeʻese i le mamao e mafai ai, ma puipuia auala e tatau ona faia pe a tatau ai e puipuia faʻalavelave faʻatasi. Mo le faʻauluina o faʻailoga e maua ai le vaivai, faigofie ona faʻalavelaveina e faʻailo mai fafo, e mafai ona e faʻaaogaina le uaea i lalo e fai ai le talipupuni e siʻo ai pe faia se galuega lelei o le maualuga-taimi fesoʻotaʻi puipuia. Parallel wiring should be avoided on the same level, otherwise distributed parameters will be introduced, which will affect the circuit. Afai e le maalofia, o le eleele faʻavae apamemea foil mafai ona faʻailoa mai i le va o le lua laina tutusa e fausia ai se tuʻusaʻo laina.

I le faʻafuainumera matagaluega, mo eseesega laina faailo, tatau ona i paga, i le mamao e mafai ai ia faia ia latou tutusa, latalata i nisi, ma le umi e le tele eseʻese.

2. O le ituaiga o uaea

I PCB uaea, o le lautele laʻititi o le faʻapipiʻiina fuafuaina e le malosi pipiʻi i le va o le uaea ma le insulator substrate ma le malosi o le taimi nei tafe i totonu o le uaea. A o le mafiafia o apamemea foil o 0.05mm ma le lautele o 1mm-1.5mm, 2A taimi nei mafai ona pasi. O le vevela e le tatau ona maualuga atu nai lo le 3. Vagana ai mo nisi faʻapitoa faʻapipiʻiga, o le lautele o isi faʻapipiʻi luga o le tutusa vaega e tatau ona tutusa lelei pe a mafai. I le maualuga o le taamilosaga, o le va o laina faʻapipiʻi o le a aʻafia ai le lapoʻa o tufatufaina capacitance ma inductance, ma faʻapea ona aʻafia ai le faʻailoga leiloa, faʻataʻamiloina mautu ma faʻalavelave faʻalavelave. I le maualuga saosaoa fesuiaʻi matagaluega, uaea vavalalata o le a aafia ai faailo faasalalauga taimi ma galu tulaga lelei. O le mea lea, o le maualalo avanoa o laina faʻapipiʻi e tatau ona sili atu pe tutusa i le 0.5 mm. E sili ona lelei le faʻaogaina o laina lautele mo PCB uaea i soʻo se taimi e mafai ai.

E tatau ona i ai se mamao va i le va o le uaea lolomiina ma le pito o le PCB (e le itiiti ifo i le mafiafia o le ipu), e le gata e faigofie ona faʻapipiʻi ma masini, ae faʻaleleia atili foʻi le faʻatinoina faatinoga.

Afai e faʻatoa mafai ona faʻafesoʻotaʻi laina faʻataʻamilomilo i se laina lapoʻa o le laina, e tatau ona tatou faʻaaogaina le laina lele, o lona uiga, fesoʻotaʻi saʻo ma le laina puʻupuʻu e faʻaititia ai le faʻalavelave na aumai e ni uaea mamao.

O le taʻamilosaga o loʻo i ai maneta maaleale vaega e maaleale i le faʻataʻamilosaga maneta fanua, ae o le loloʻu o uaea o maualuga-taimi matagaluega e faigofie e susulu eletise electromagnetic. Afai o elemeni maaleale elemeni o loʻo tuʻuina i le PCB, e tatau ona mautinoa o loʻo iai se vaʻaiga va i le va o le tulimanu o uaea ma ia.

Leai se faʻataʻitaʻiga e faʻatagaina ile tutusa tulaga ole uaea. Mo le laina e ono sopoʻia, mafai ona faʻaaogaina le “vili” ma le “manuʻa” auala e foia ai, ia avea se taʻitaʻiga mautinoa e mafua mai isi teteʻe, capacitance, audion ma isi masini taʻitaʻi vae vaʻavaʻai nofoaga “toleni” ua tuanaʻi, pe mai le faʻaiuga o le mautinoa nisi e ono sopoia “manuʻa” ua tuanaʻi. I tulaga faʻapitoa e matua faigata ai le faʻataʻamilosaga, ina ia faʻafaigofie ai le ata, e faʻatagaina foi ona foʻia le faʻafitauli o le felavasaʻi ma le fusia o uaea.

A o le maualuga alualu i luma faagaoioia i se maualuga taimi, o le impedance fetaui lelei ma antenna aafiaga o uaea e tatau foi ona iloiloina.

Talu ai na mulimuli ane suia e le tagata o tausia le maliega talu ai ma manaʻomia le faʻauigaina o faʻamatalaga ma le faʻatulagaina e pei ona faʻamatalaina e latou, na latou suia le faʻatulagaga i le ata i le itu taumatau. O le mea moni, o le atoa PCB na o 9cm x 6cm. E faigata ona suia le faʻatulagaina atoa o le laupapa e tusa ai ma manaʻoga o tagata faʻatau, o lea o le vaega autu o le laupapa e leʻi suia i le iuga, ae o le peripheral vaega na fesuiaʻia talafeagai, mafuli tulaga o le lua fesoʻotaʻiga ma le faʻamatalaga o pine na toe faʻaleleia.

Ae o le fou faʻatulagaina mautinoa mafua ai nisi faʻafitauli i le laina, o le amataga lamolemole laina avea a le laʻitiiti, o le umi o le laina faʻateleina, ae e tatau foi ona faʻaaoga le tele o pu, o le faigata o le laina na faʻateleina tele.

3. Manaoga manaʻomia mo uaea eletise ma uaea uaea

Faʻateleina le lautele o le paoa eletise e tusa ai ma eseese taimi faigaluega. Hf PCB tatau ona faʻaaogaina le tele o le eleele uaea eleele ma faʻataʻatia luga o le pito o PCB i le mamao e mafai ai, lea e mafai ona faʻaititia ai le faʻalavelaveina o fafo faʻailo i le matagaluega; I le taimi e tasi, o le grounding uaea o PCB mafai ona fesoʻotaʻi lelei ma le atigi, ina ia o le grounding voltage o PCB e latalata i le lalolagi voltage. O le grounding mode tatau ona filifilia e tusa ai ma le tulaga moni. Eseese mai le maualalo-taimi matagaluega, o le uaea faavae o le maualuga-taimi matagaluega tatau ona latalata pe tele-togi grounding. O le uaea uaea e tatau ona puʻupuʻu ma mafiafia e faʻaititia ai le eleele impedance, ma le faʻatagaina alavai tatau tatau ona faʻatolu taimi o le galulue nei. O le failauga grounding uaea e tatau ona faʻafesoʻotaʻi i le PCB mana amplifier tulaga faʻavae tulaga faʻavae tulaga, aua le faʻavae faʻavae.

I le faʻagasologa o fesoʻotaʻiga tatau lava ona i ai i le taimi o ni nai loka talafeagai loka, neʻi toe faia faʻamau mo le tele o taimi. Ina ia lokaina i latou, tamoe le EditselectNet poloaiga e filifili Lokaina i muaʻi uaea meatotino.
