8 Layer FR4 ENIG Impedance Control PCB
Impedance ke motsoako oa capacitance le inductance ho sitisa potoloho tlas'a letšoao le phahameng la maqhubu.Impedance ke tšobotsi ea AC, e bolelang hore e itšetlehile ka makhetlo a mangata.Tabeng ea ho fetisa lipontšo tse phahameng-frequency, impedance e laoloang e thusa ho etsa bonnete ba hore ha ho na ho fokotseha ho hoholo ha pontšo nakong ea phetisetso.Ha e le hantle, impedance e laoloang e bolela hore litšoaneleho tsa thepa ea substrate li lumellana le litšoaneleho tsa mohala / dielectric lera ho netefatsa hore boleng ba impedance ea letšoao la mohala bo ka har'a mamello ea boleng ba boitsebiso.
Boiphihlelo ba ho Hlahisa Sebakeng sa Taolo ea Impedance
Impedans Modelling Software And Impedans Testing Hardware
HUIHE Circuits e sebelisa software ea ho etsa mohlala oa impedance le lisebelisoa tsa tlhahlobo ea impedance ho fihlela litlhoko tsa hau tsa taolo ea impedance.Lisebelisoa tsa "speedstack" le "CITS" tsa Polar li kopanya litharollo tsa masimo a boleng bo holimo le laeborari ea lisebelisoa tse felletseng ho netefatsa hore moralo oa hau o ka atleha hang le ka ho sa feleng.
Tlhahlobo e Kenang Le Tsamaiso ea Tsamaiso ea Bafani
Ka tšebelisano-'moho le bafani ba thepa ba ka sehloohong, mokhoa oa ho fepa o tiisa ts'ebetso e tsitsitseng le lisebelisoa tse fumanoang tse tala (laminates, PP, foil ea koporo).
Lisebelisoa tsa ho etsa litšoantšo tsa Laser Direct
Thepa ea LDI e qoba liphetoho tsa bophara ba mela ka lebaka la ho atolosoa / ho fokotseha ha filimi e omeletseng, 'me ka nako e ts'oanang e hlahisa setšoantšo se hlakileng holim'a holim'a koporo, e leng se etsang hore ho be le ho nepahala ho phahameng ho etching line.
Etching Equipment Configuration
Hang ha PCB ea taolo ea impedance e pepesitsoe ho nts'etsopele e tlameha ho kenngoa mochining oa etching bakeng sa etching.Etcher e tlameha ho beha liparamente ka nepo joalo ka lebelo, mocheso, khatello, tataiso ea nozzle le Angle ho fokotsa khoholeho ea lehlakore.Ka boiphihlelo ba lilemo tse ngata indastering ea boto ea potoloho e hatisitsoeng, Hui He Circuit e thehile mokhoa o holileng oa ho etsa bonnete ba hore bareki ba hloka mamello e tiileng ea impedance.
Lintlha tse Amang Tšitiso
Botenya ba dielectric:ke ntho ea bohlokoa ka ho fetisisa e amang boleng ba liboto tsa PCB tse hatisitsoeng
Bophara ba mela / sebaka sa mela:eketsa bophara ba mohala ho fokotsa sekhahla, 'me u fokotse bophara ba mohala ho eketsa sekhahla.
Botenya ba koporo:fokotsa botenya ba mola, eketsa tšitiso, eketsa botenya ba mola, 'me u fokotse tšitiso
Dielectric constant:Ho eketsa khafetsa ea dielectric ho ka fokotsa tšitiso, 'me ho fokotsa sekhahla sa dielectric ho ka eketsa tšitiso.The dielectric constant e laoloa haholo ke thepa
Molemo oa Rōna
1.Ho feta lilemo tse 10 tsa boiphihlelo ba tlhahiso ea impedance, ho laola ka thata bophara ba terata le botenya ba mahareng
2. Emisa mokhoa oa tlhahiso ho netefatsa mamello e tiileng ea impedance
3. Setifikeiti se felletseng sa sehlahisoa le netefatso ea sistimi ea feme
