Blind Via Image Impedance Tracks









Lower Than 5% Impedance Tolerance Achievable With Candors Process

With todays digital signal processing using higher clock frequencies and shorter signal transition times PCB tracks need to be considered as transmission lines with regulated impedance. Impedance is controlled by the dimensions, materials, and configurations of the PCB.

How We Achieve Our Tight Tolerances

Candor uses Polars CITS500s Controlled Impedance Test System, with this system Candor is able to determine the characteristic impedance of traces to ensure products meet customer standards. Candor can reach up to 2% tolerance of impedance controlled traces thanks to Panel Plating and Continuous Foil Lamination.

Uniform Plating

Candor uses a panel plating process that gives uniform plating across all boards which is needed for uniform signal propagation, keeping impedance tolarances withing required levels.

Dielectric Layer Consistency

To get a smooth and consistent dielectric layer Candor uses continuous foil lamination with induction heating to maintain temperature across B-Stage pre-pregs. This results in a consistent dielectric layer thickness, allowing for uniform signal propagation with minimal track impedance variation.

What Is the Application?

Impedance Control should be considered when dealing with high speed/frequency digital and analog circuits. Designers specify these types of PCBs whenever the edge speeds of digital signals are faster than 1ns, or analog signals climb above 300MHz.





This is a technology that allows the manufacturer to assemble electronic components onto a flexible PCB substrate rather then the generic rigid PCB.

Application for Flexible Printed Circuit Boards

Flexible circuits are used where spacial constrainted limit the use of rigid circuit boards or designs require movable parts.

What Is Unique About Candor's Blind Buried Via

With our simplified process we are able to manufacture sequential blind-buried vias with or without via filling.

Sequential Blind Via With Candor Landless Via Technology!

With our landless via technology we can reduce spacing constraints. This gives our customers an design advantage compared to going to a conventional PCB manufacturer.

The Candor Advantage for Heavy Copper PCBs

With our Panel Plating Technology heavy copper boards have superior even plating. We can put 6 oz of copper evenly in the hole as well! With our PPG liquid photo resist. deep trenches have no issues and close to perfect etching is achieved.


Heavy Copper Boards:

Heavy Copper Board







Metal backed copper boards have a base layer made of a metal substrate. This substrate is bonded to the circuit and dielectric layers of a board

Application

This product is mainly used for high heat transfer designs such as:

  • Power Electronics
  • LEDs
  • Electric Drives
  • Automotive

The Candor Advantage for Metal Backed Copper Boards

We use aluminum oxide epoxy, this gives superior heat transfer than prepreg style which is used in a conventional process.

Application:

Thicker PCBs are useful when dealing with one or more of the following:

  • Stability Issues
  • Mounting Difficulties
  • Desire to segregate power and ground

The Candor Advantage For Thick Copper PCB's

Candor is able to create PCBs with a maximum thickness of 0.380 inches. High spindle speed drilling machines allow for superior tolerance with very thick PCB's. We have done 0.380" thick PCB's with +/- 0.001" finished hole size and +/- 0.001" positional tolerance and continue to push the specs!

These types of circuit boards are used when dealing with signal frequencies in the RF and Microwave range. They differ from other PCBs through the use of special materials that help propagate signal frequencies. Candor uses Rogers, Arlon, Teflon, and GETEK materials depending on the customers requests. We also work with hybrid materials as well.

Candor Features

Dielectric Layer Consistency

To get a smooth and consistent dielectric layer Candor uses continuous foil lamination with induction heating to achieve uniform heating. This gives a consistent dielectric layer thickness, allowing for uniform signal propagation.

Uniform Plating

Candor uses a panel plating process that gives uniform plating across all boards which is needed for uniform signal propagation, an important feature when dealing with radio and microwave frequencies.
