What is Taconic PCB – classifications, benefits & applications
What is Taconic PCB?
Taconic PCB is a ceramic filled poly-tetra-fluoro-ethylene-based printed circuit board. It has high frequency, flexibility, and low dissipation rate.
Besides, Engineers use it for lower signal loss, high efficiency, and budget-friendliness. The circuit board is suitable for communications, RF applications, and the aerospace industry.
What is Taconic material?
In Taconic PCBs the materials used are called Taconic materials. These are Ceramic-filled Polytetrafluoroethylene or woven glass-reinforced materials.
These materials are used because of their adapted dielectric permittivity, low attenuation for efficient signal processing transmission, and wide range of dielectric constants.
Types of Taconic laminates
There are several Taconic laminates based on the frequency and building materials. These laminates are used for cellular communications, power amplifiers. So, let’s look at the variety of Taconic laminates classes.
Some popular Laminates based on building materials:
1. Woven glass-reinforced PTFE laminates: These types of Taconic PCB laminates are built with a woven matrix of fiberglass fabric coated with PTFE materials. It’s used for low-cost antenna and military-grade low-cost Dk base materials. Such as TLY, TLC, TLA, etc.
●TLY-5: TLY-5 is constructed with copper, aluminum, and brass. And it is used for radar, satellite, and cellular communication.
●TLY-5A is a high-frequency stable reinforced with woven glass like Taconic laminates. The primary purpose of this laminate is used in the radar industry and power amplifiers.
2. Ceramic-filled PTFE laminates: Ceramic-filled PTFE laminates are cheap and supply the best performance in microwave and radio wave applications. These types of laminates are reinforced with fluoropolymer chemistry with ceramic elements’ thermal, mechanical and electrical enhancements. Such as RF-35, RF-30A, RF-10, etc.
●RF-35: This laminate is the perfect solution for power amplifiers, microwave applications, and several hybrid builds.
3. Hydrocarbon laminates: Hydrocarbon laminates are constructed with dielectric layers based on polybutadiene. Mainly it’s used for microstrip/stripline antennae and power amplifiers. Such as HF-341, HF-340, HF-300F, etc.
What is the difference between Taconic PCB and Isola PCB?
Isola & Taconic PCB both are designed for using high frequency applications, but main differences is construct materials.

Benefits of Taconic PCB
High workability: Taconic keeps its original performance almost in every situation whenever exposed to heat and cold.
Low-cost circuit: The manufacturing cost is budget-friendly. Also, This ceramic-filled laminate offers the best value for its price.
Low signal loss: For broad applications such as GSM, Satellite transfers continuous signal over a long distance. It doesn’t occur any signal loss.
Provide a wide range of dielectric constants: Dielectric constant means the ability to store electrical energy, or mathematically it’s a ratio of material’s permittivity (k = ϵ/ϵ0).
A dielectric material has weak electrical conductivity and accumulates lots of charges. Taconic PCBs are a wide range of dielectric constants, so the circuit’s efficiency is better.
Slow humidity absorption: Humidity is inversely proportional to the dielectric constant. And Humidity is harmful to PCBs’ durability. So, the lower moisture absorption is excellent for a circuit board. Lower absorption extends PCBs’ life.
Low dissipation factor: The dissipation factor measures the inefficiency of insulating materials.
Excellent stability: Taconic PCBs have great strength in thermal and electrical properties. Sometimes the circuit gets hot. Taconic is both compatible with hot and cold weather in a limit.
Applications of Taconic PCB
●Telecommunications: PCN Antennas, Passive components, Power amplifiers and transmitters, GSM, UMTS.
●Automotive: High-temperature reliability, Keyless entry systems, Tire pressure monitoring, Car Diagnosis
●Multilayer: chip testing, Digital multilayer
●Mechanical: Flexible PCB
●Medical equipment: Medical imaging, Artificial organs, Bioinformatics, etc.
Fundamental lamination techniques in multilayer Taconic PCB manufacturing
PTFE microwave lamination is very common and most popular for engineers. These lamination technologies are an ideal option for every radiofrequency device. Because of:
●Lower signal loss
●Wide range of dielectric constant
Double-sided PCBs: If we compare single and double layer PCB, both are the same. But the main difference is that double-sided PCBs have two-sided traces with a top and bottom layer. The main application of a double-sided is Amplifiers, LED system, Car dashboard, etc.
Sequential lamination: This type of lamination method is used for performing two or multiple subsets. In sequential lamination, several layers combine each other in various procedures.
Multilayer PCBs: Thin etched boards or trace layers denote multilayer Taconic PCBs. The Circuit board exposed its multiple layers to very high pressure and temperature during the lamination process. It is made with three or four copper layers laminated together. The primary purpose of multilayer PCBs is to be used on complex systems such as data servers, smartphones, GPS systems, scientific and space equipment, heart monitor, etc.
Factors to consider in hybrid fbrication of Taconic PCB
When fabricating a hybrid Taconic PCB, some parameters should follow. These factors play a vital role in PCBs quality and signal processing.
Materials: For matching the lamination cycle, it’s essential to stack-up materials. Before doing something must read the datasheet. Sometimes materials require a variety of pressure and temperature during lamination.
Drilling: The primary factor considers when doing hybrid fabrication is exact hole formation in boards. Usually, proper speeds and feed is perfect for a Taconic PCB component.
Electric components dispense heat, which can play a vital role in deformation. Also, the meals and rates of the drill are determined by the stack-up materials.
Making of hole wall: Generating a hole wall is essential for the highest efficiency. It’s come after the drill parameters. Follow instructions before doing anything.
Overall Taconic PCB is great for long distance communication systems and demandable for every engineers. The quality of these types of PCB are great and better than other categories according to price and materials.
