Dense Digital Boards With Controlled Return Paths
Telecom boards are dense, they run fast, and they have to pass emissions testing. That combination pushes layer count up and design rules down. Our rigid line runs to 16 layers with 0.075 mm trace and space, which is the envelope most of this work sits inside.
What Actually Fails In Telecommunication
Four failure modes specific to this sector, and the published figure that each one is controlled by.
Emissions
A continuous inner ground plane gives every fast signal a short return path, which fixes most emissions problems before they reach the test house.
Escape routing
Multi-BGA designs consume routing layers just getting out of the package. Ten and twelve layer builds give those layers back.
Slot fit
Line cards go into a fixed slot pitch. Outline tolerance of ±0.10 mm and hole position of ±0.05 mm keep the card in its guides.
Connector wear
Cards that are re-seated during maintenance need electroplated gold, not immersion.
Boards We Build For This Sector
Telecom work is mostly eight to twelve layer rigid with immersion gold, with electroplated gold where edge fingers are mated repeatedly. Send the impedance profile with the stack-up.

Telecommunication Questions
Can you hold controlled impedance?
Send the target impedance and tolerance per net with your stack-up and we will confirm it against available laminate thicknesses before tooling.
What is your highest layer count?
16 layers is the published limit on our rigid capacity table.
Do you build backplanes?
Twelve layer boards with edge connectors are in the catalogue and are the usual backplane construction.
