 O le a le High Speed ​​PCB?

O le "High Speed" e masani ona faauigaina o le taamilosaga lea e sili atu le umi o le si'i a'e po o le pa'u o le faailo nai lo le tasi vae ono o le umi o le laina fa'asalalau e sili atu nai lo le umi o le laina fa'asalalau, ona fa'aalia lea e le umi o le laina laina le amio tu'ufa'atasi.

I se PCB maualuga maualuga , o le taimi tulaʻi e vave lava e mafai ai e le bandwidth mo le faʻailoga numera ona faʻalauteleina i le maualuga MHz poʻo le GHz. Pe a tupu lenei mea, o loʻo i ai faʻafitauli faʻailoga faʻapitoa o le a matauina pe a le fuafuaina se laupapa e faʻaaoga ai tulafono faʻatulagaina PCB maualuga. Aemaise lava, e mafai ona matauina e se tasi:

1. Fa'alogoina tele le tatagi. E masani ona tupu lenei mea pe a le lava le lautele o faʻailoga, e ui lava e tatau ona e faʻaeteete pe a faʻalautele lau faʻasologa (vaʻai le vaega ile Impedance Contorl ile PCB Design i lalo). Afai e fai si tele o le tatagi le tumau, o le a tele lau ova po'o lalo ifo i au suiga faailo.

2. Feso'ota'iga malosi. A'o fa'atupula'ia le saosaoa o fa'ailo (fa'ata'ita'iga, a fa'aitiitia le taimi fa'atupu), e mafai ona fai si tele o le tautalaga fa'amalosi pe a o'o i le taimi nei le fa'alavelave malosi.

3. Mafaufauga ese o le avetaavale ma vaega e taliaina. O au faailo e mafai ona atagia mai isi vaega i soʻo se taimi e iai se faʻalavelave le fetaui. Pe taua pe leai foi le le fetaui o le impedance e manaʻomia le vaʻavaʻai i le faʻaogaina o le impedance, impedance o le uta, ma le faʻaogaina o le laina faʻapitoa mo se fesoʻotaʻiga. E mafai ona e faitau atili e uiga i lenei mea i le vaega o loʻo mulimuli mai.

4. Fa'afitauli fa'amaoni o le malosi (fa'alavelave PDN le tumau, fa'a'ele'ele, ma isi). O le isi lea seti o faʻafitauli e le maalofia i soʻo se mamanu. Ae ui i lea, e mafai ona fa'aitiitia tele le fa'aputuga o le PDN ma so'o se mea e tupu mai ai EMI e ala i le fa'atulagaina lelei o le fa'aputuga ma faiga fa'a'ese'ese. E mafai ona e faitau atili e uiga i le saoasaoa maualuga PCB stackup mamanu mulimuli ane i lenei taiala.

5. Malosi fa'atautaia ma fa'aola EMI. O le suʻesuʻega o le foia o faʻafitauli EMI e lautele, e le gata i le IC ma le maualuga o le PCB design level. EMI ose faiga fa'afeagai; afai e te mamanuina lau laupapa ina ia malosi le puipuiga o le EMI, ona faʻaitiitia lea o le EMI. Toe foʻi, o le tele o nei mea e faʻapipiʻi i lalo i le mamanuina o le faʻapipiʻi PCB saʻo.

O PCB maualuga-telefoni e masani ona tuʻuina atu le tele o taimi mai le 500MHz i le 2 GHz, lea e mafai ona faʻafetaui manaʻoga o mamanu PCB maualuga, microwave, leitio, ma telefoni feaveaʻi. A o'o i luga ole 1 GHz le fa'asologa, e mafai ona tatou fa'auigaina ole maualuga ole taimi.

O lo'o fa'atupula'ia pea le lavelave o vaega fa'aeletonika ma suiga i aso nei ma e mana'omia ai le fa'avavevave o le tafe o fa'ailoga. O lea la, e mana'omia le tele o fa'asalalauga. E fesoasoani tele PCBs maualuga pe a tuʻufaʻatasia manaʻoga faʻapitoa faʻailoga i vaega faʻaeletoroni ma oloa ma mea lelei e pei o le maualuga maualuga, ma le saoasaoa vave, lalo ifo o le attenuation, ma le tumau dielectric properties.Some considerations of high-frequency PCBs designs

O PCB maualuga e masani ona faʻaaogaina i leitio ma telefoni feaveaʻi, e pei ole 5G fesoʻotaʻiga uaea, masini radar taʻavale, aerospace, satelite, ma isi. Ae e tele mea taua e tatau ona mafaufauina pe a gaosia PCBs maualuga.

· Fuafuaga fa'apipi'i tele

E masani ona matou faʻaogaina le tele-layered PCBs i mamanu PCB maualuga. O PCB fa'apipi'i tele e iai le tele o fa'apotopotoga ma le la'ititi la'ititi, e fa'apena ona fetaui lelei mo afifi a'afiaga. Ma e faigofie tele laupapa faʻapipiʻi e faʻapuʻupuʻu fesoʻotaʻiga i le va o mea faʻaeletoroni ma faʻaleleia le saoasaoa o faʻasalalauga faʻailoga.

O le fuafuaina o vaalele eleele o se vaega taua o talosaga maualuga ona e le gata ina faatumauina le lelei o faailo ae fesoasoani foi e faʻaitiitia ai faʻasalalauga EMI. O le maualuga o le laupapa faʻapipiʻi mo faʻaoga uaealesi ma fua faʻamaumauga i le pito i luga o le GHz e iai manaʻoga faʻapitoa i mea faʻaaogaina:

1. Fetuuna'i le faatagaina.

2.Low attenuation mo le faʻaogaina lelei o faailoilo.

3. Faufale tutusa ma le maualalo tolerances i insulation mafiafia ma dielectric tumau. Le manaʻoga mo oloa PCB maualuga-telefoni ma maualuga-saosaoa tulai vave i aso nei. I le avea ai o se tagata gaosi oloa PCB , o loʻo taulaʻi atu le YMS i le tuʻuina atu o tagata faʻatau ma faʻataʻitaʻiga PCB maualuga maualuga ma le maualuga. Afai ei ai ni ou faʻafitauli i le PCB fuafuaina poʻo le gaosiga PCB, faʻamolemole lagona le saoloto e faʻafesoʻotaʻi i matou.
