Taconic TLY-5 PCB Manufacturer for 77 GHz Radar and Antennas

Highleap Electronics reviews, fabricates, and assembles Taconic TLY-5 PCBs for 77 GHz radar, antenna arrays, satellite and cellular RF, power amplifiers, and other low-loss mmWave circuits. The service is built around the finished RF structure: material thickness, copper profile, critical geometry, ground-via pattern, surface condition, assembly hardware, and the customer’s measurement method.

RF build review: Highleap supports TLY-5 prototypes and production builds after reviewing the files, RF geometry, stackup, and acceptance method. Low Dk and low loss can be valuable for antennas and mmWave circuits, while temperature stability, glass weave, mechanical support, and test correlation are evaluated for the actual product.

TLY-5 Antenna and mmWave PCB Manufacturing Support

Highleap can support TLY-5 antenna, radar, and mmWave boards with controlled impedance, via fences, plated transitions, multilayer or hybrid constructions, and RF-sensitive assembly requirements. Large panels, thin dielectric structures, unusual antenna geometries, or advanced interconnect are reviewed around the real RF target, laminate construction, panel stability, and process yield instead of being treated as standard catalogue limits.

Important: TLY-5 projects can be built from development samples through validated production volumes. When the application has special frequency, environmental, interconnect, or test requirements, Highleap reviews the manufacturing route before quoting the final construction.

Can TLY-5 Meet Your 77 GHz or Antenna Requirement?

Taconic TLY-5 is a low-Dk, very-low-loss PTFE laminate reinforced with lightweight woven fiberglass. AGC publishes a nominal Dk of 2.2 ± 0.02 and a dissipation factor of 0.0009. The low dielectric constant supports relatively wide transmission lines, low dielectric loading, and efficient antenna or feed-network structures.

At 77 GHz, the material name is only the starting point. Etched line width, gap, copper profile, dielectric thickness, glass orientation, antenna outline, launch geometry, surface finish, and enclosure spacing can shift the actual response. Highleap therefore quotes TLY-5 as a controlled RF structure, not as a generic PTFE board.

Highleap TLY-5 PCB Manufacturing Scope

Highleap can review TLY-5 designs for single- or double-sided RF boards, multilayer RF constructions, and mixed-material stackups. The project may include bare-board fabrication, component sourcing, SMT/through-hole assembly, shield and connector processing, and customer-defined RF or functional testing.

Prototype feasibility does not guarantee volume yield. The quotation should identify which dimensions and tests will be controlled in both the first article and repeat production.

Stackup and Geometry Rules for mmWave PCBs

A 50-ohm line on a Dk 2.2 material is generally wider than the same line on a high-Dk laminate. Wider traces can be more robust to etch variation, but the electric field also extends farther into adjacent space. Copper keep-outs, board-edge distance, solder mask, housing metal, connectors, and nearby structures therefore become part of the RF model.

Inputs that must be frozen

• exact TLY-5 thickness and tolerance;
• copper type, starting copper, plated copper, and roughness model;
• microstrip, stripline, grounded coplanar, or antenna geometry;
• mask over the line, mask clearance, or no-mask requirement;
• critical line, gap, pad, slot, edge, and connector tolerances;
• glass-weave orientation and routing orientation where phase matching is sensitive;
• measurement reference planes, de-embedding, and acceptance limits.

For differential or parallel paths, a generic claim that TLY-5 “eliminates skew” is wrong. Woven reinforcement can still create local effective-permittivity variation. The actual risk depends on line width, pair spacing, route angle, laminate thickness, glass style, and length. Provide an allowed phase or time mismatch if it matters to the product.
