 PCB ea lebelo le phahameng ke eng?

"Lebelo le Phahameng" ka kakaretso le hlalosoa ho bolela lipotoloho moo bolelele ba moeli o nyolohang kapa o theohang o moholo ho feta hoo e ka bang karolo ea botšelela ea bolelele ba mohala oa phetisetso ho feta bolelele ba mohala oa phetisetso, ebe bolelele ba mohala oa phetiso bo bonts'a boitšoaro ba mohala oa lumped.

Ka lebelo , nako ea ho phahama e potlakile ka ho lekaneng hoo bandwidth ea lets'oao la dijithale e ka fetelang ho maqhubu a phahameng a MHz kapa GHz. Ha sena se etsahala, ho na le mathata a itseng a pontšo a tla hlokomeloa haeba boto e sa etsoa ho sebelisoa melao ea moralo oa PCB ea lebelo le phahameng. Haholo-holo, motho a ka hlokomela:

1. Ho lla ho hoholo ha nakoana ho sa amoheleheng. Hangata sena se etsahala ha mesaletsa e se na bophara bo lekaneng, leha o hloka ho ba hlokolosi ha o etsa hore mesaletsa ea hau e atolohe (sheba karolo ea Impedance Contorl ho PCB Design ka tlase). Haeba ho lla ha nakoana ho le holo haholo, o tla ba le leqhubu le leholo kapa letlobo le tlase ho liphetoho tsa hau tsa mats'oao.

2.Strong crosstalk. Ha lebelo la lets'oao le ntse le eketseha (ke hore, ha nako ea ho nyoloha e ntse e fokotseha), capacitive crosstalk e ka ba kholo haholo joalo ka ha boiphihlelo ba hona joale bo susumetsoa ke capacitive impedance.

3.Reflections theoha ea mokhanni le moamoheli likarolo. Lipontšo tsa hau li ka bonts'a likarolo tse ling neng kapa neng ha ho na le ho se lumellane ha impedance. Hore na ho se lumellane hoa bohlokoa kapa che ho hloka ho shebisisa ho sitisoe ke letho, ho sitisoe ke thepa, le mokhoa oa phetisetso oa sebopeho sa sehokelo bakeng sa khokahano. U ka bala haholoanyane ka sena karolong e latelang.

4.Mathata a botšepehi ba matla (ripple ea nakoana ea PDN, bounce ea fatše, joalo-joalo). Ena ke sete e 'ngoe ea mathata a ke keng a qojoa moqapi ofe kapa ofe. Leha ho le joalo, ripple ea nakoana ea PDN le EMI efe kapa efe e hlahisoang e ka fokotsoa haholo ka moralo o nepahetseng oa li-stackup le mehato ea ho kopanya. U ka bala haholoanyane mabapi le moralo oa li-stackup tsa PCB hamorao bukeng ena.

5.Strong e entsoeng le ho khantša EMI. Boithuto ba ho rarolla mathata a EMI bo batsi, ka bobeli boemong ba IC le boemo bo phahameng ba moralo oa PCB. EMI ha e le hantle ke mokhoa o lumellanang; haeba u rala boto ea hau ho ba le ts'ireletso e matla ea EMI, joale e tla ntša EMI e fokolang. Hape, boholo ba sena se itšetlehile ka ho rala sephutheloana se nepahetseng sa PCB.

Li-PCB tsa maqhubu a phahameng hangata li fana ka sebaka sa maqhubu ho tloha ho 500MHz ho isa ho 2 GHz, se ka fihlelang litlhoko tsa meralo ea lebelo le holimo ea PCB, microwave, radiofrequency, le lisebelisoa tsa mohala. Ha maqhubu a le ka holimo ho 1 GHz, re ka e hlalosa e le maqhubu a phahameng.

Ho rarahana ha likarolo tsa elektroniki le li-switches li ntse li eketseha matsatsing ana 'me li hloka lebelo la phallo ea matšoao. Kahoo, ho hlokahala maqhubu a phahameng a phetiso. Li-PCB tsa maqhubu a phahameng li thusa haholo ha li kopanya litlhoko tse khethehileng tsa mats'oao ho likarolo tsa elektroniki le lihlahisoa tse nang le melemo e kang ts'ebetso e phahameng, le lebelo le potlakileng, ho theola boima ba 'mele, le thepa e sa fetoheng ea dielectric.

Li-PCB tsa maqhubu a phahameng li sebelisoa haholo-holo lits'ebetsong tsa seea-le-moea le tsa lebelo le phahameng, tse kang puisano e se nang mohala ea 5G, li-sensor tsa radar tsa likoloi, sefofane, li-satellite, joalo-joalo Empa ho na le lintlha tse ngata tsa bohlokoa tse lokelang ho nahanoa ha ho etsoa li-PCB tse phahameng haholo.

· Moralo o nang le mekhahlelo e mengata

Hangata re sebelisa li-PCB tse nang le li-multi-layered ka meralo ea PCB ea maqhubu a holimo. Li-PCB tse nang le mefuta e mengata li na le bongata ba kopano le molumo o monyenyane, o li etsang hore li tšoanelehe haholo bakeng sa liphutheloana tsa tšusumetso. 'Me mapolanka a nang le mefuta e mengata a loketse ho khutsufatsa likamano pakeng tsa likarolo tsa elektronike le ho ntlafatsa lebelo la phetisetso ea matšoao.

Moralo oa sefofane sa fatše ke karolo ea bohlokoa ea lits'ebetso tse phahameng haholo hobane ha e boloke boleng ba matšoao feela empa e boetse e thusa ho fokotsa mahlaseli a EMI.Boto ea maqhubu a phahameng bakeng sa lits'ebetso tse se nang mohala le litefiso tsa data sebakeng se kaholimo sa GHz li na le litlhoko tse khethehileng tsa thepa e sebelisoang:

1. Tumello e fetotsoeng.

2.Low attenuation bakeng sa phetiso e nepahetseng ea matšoao.

3.Homogeneous mohaho o nang le mamello e tlaase ka botenya ba ho kenya letsoho le ho lula ha dielectric. Tlhokahalo ea lihlahisoa tse phahameng le tse lebelo le holimo tsa PCB e nyoloha ka potlako matsatsing ana. Joalo ka moetsi PCB , YMS e shebane le ho fa bareki prototyping e tšepahalang ea maqhubu a holimo ea PCB ka boleng bo holimo. Haeba u na le mathata afe kapa afe ka moralo oa PCB kapa tlhahiso ea PCB, ka kopo ikutloe u lokolohile ho ikopanya le rona.
