TSM-DS3 PCB: 2-Layer, 30mil Core, 0.8mm Thickness with Immersion
Gold Finish
(All PCBs are custom-manufactured. Reference images and parameters
may vary based on your design requirements.)
Overview of TSM-DS3 2-Layer PCB
The TSM-DS3 PCB is a high-performance 2-layer rigid PCB designed
for high-power, low-loss, and thermally stable applications. Built
with TSM-DS3 materials, this PCB features a 30mil (0.762mm) core
and a finished thickness of 0.8mm, providing low dielectric loss
and excellent thermal conductivity.
With a dielectric constant (Dk) of 3.0 ± 0.05 and dissipation
factor (Df) of 0.0014 at 10 GHz, the TSM-DS3 PCB is a reliable
choice for radar systems, phased array antennas, and high-frequency
automotive applications. The Immersion Gold (ENIG) surface finish
ensures excellent solderability, corrosion resistance, and
long-term durability.

Introduction to TSM-DS3 Material
The TSM-DS3 laminates are ceramic-filled, reinforced materials with
minimal fiberglass content (~5%), developed for high-power RF
applications. These materials provide dimensional stability, low
loss, and thermal reliability, combining the benefits of ceramics
and traditional epoxy laminates.
