Microwave Loj Loj PCB

Lub microwave pcb yog ib qho tshwj xeeb Circuit Court board engenered rau 300 mHz ~ 300 ghz zaus, muab ob lub zog tseem ceeb:
1. Cov paib kis tus kis tau: propagate micrage ntsuas nrog tsawg heev;
2. EM Fidel tswj: Kev tswj hwm Electromagnetic teb kev faib tawm ntawm precision qauv qauv.
3. Cov ntsiab lus tseem ceeb
Cov ntaub ntawv: Qis {{{- Poob substrates (PTFE, Ceramic {}} {}} ~ 10.8
Tooj Liab: HVLP Ntawv Nyiaj (RA<0.5μm) for reduced skin effect
Cov qauv tseem ceeb:
Kev tswj - Impredance Cov Kab (50ω ± 2%)
EMI Supression ntawm Feet / DGS
Direct - muab cov ntawv sib cuam tshuam mmic interfaces

2. Ruaj ntseg dielectric tas li (DK)
DK temp. coefficiess tsawg dua lossis sib npaug rau -50 ppm /℃(-55℃~ 150 degree), tiv thaiv zaus txav mus los
Rooj plaub: Rogers Ro3003 ™ ΔDK<±0.02 @40GHz

3. Qhov kev tsim nyog los tswj
50% LAWM LAWM ± 1% (qhov tseeb ntawm qhov chaw ± 0.015mm), me ntsis xav
Tech: Laser Ncaj Nraim (LDI) rau ± 5μm precision

4. Optimized tooj liab ntawv nyiaj
HVLP tooj liab (RA =0.3 μm) txo cov tawv nqaij poob ntawm 30% (@ khawm)
Kev sib piv: Cov khoom ntawv ci (ra {=2 μm) ntxiv 2db / m poob @ 60.hl

5. 3 d thermal kev tswj hwm
Metal-core substrates (Al/Cu) with >2w / (mapx k) kev coj ua, tuav 100w + fais fab
Kev Tsim Kho **: Embedded Thermal Vias + Cov Kav Dej Sov

6. Em daim teb precision
Ntawm laj kab (spacing<λ 10)="" suppress="" edge="">
Tshwj Xeeb: Kev tiv thaiv av uas tsis sib xws (DGS) rau kev tiv thaiv zoo

7. Cov txheej txheem hybrid sib xyaw ua ke
Mixed stackup: RF txheej (PTFE) + cov digital khaubncaws sab nraud (m6g)
Chip Kev Sib Tw: Kub Hlau Tsevneeg (<0.5° phase error)

Khoom Daim Ntawv Thov Teb

Microwave PCBs (** 300 MHz - 300 ghz **) yog qhov tseem ceeb hauv:
