HDI Micro Via/Blind and Buried

  Due to the growing complexity of design structures, high-density circuit boards (HDI) are being used more and more, especially in todays high-tech products. As these products increase in functionality and decrease in size and weight, circuit board engineers need new solutions to maximize space on each board. Blind and buried vias, vias-in-pad and microvias of .006 or less in diameter, with higher circuitry density than traditional circuit boards add complexity to the design, but let you do more with less. Circuit Tech Inc. has continuously focuses on these advanced technologies.

CAM Engineering Analysis

Designed For Manufacturing

In order to assure PCB reliability and reduce potential issues during manufacturing, Circuit Tech Inc. adopts the board design verification process as a fully automated application that  augments the extensive manual checking of PCB design / layout. The Frontline PCB Solutions InPlan performs qualitative and quantitative analysis on all designs prior to releasing data for manufacturing. The integration of Genesis into our Design for Manufacturer (DFM) and Design for check (DRC) procedure provides accurate information that is relayed to our customer and results in a decrease in revision changes, an improvement in PCB reliability and manufacturing yields. The software application has high level of automation that is key in providing maximum levels of repeatability into our processes. 


NetList Comparison

Added Quality Control

A netlist is a list of components (i.e. Integrated circuits, resistors, capacitors etc.) and all interconnections. When an IPC-D-356 or Mentor neural file is supplied with Gerber format design files a comparison between the two is made to assure that it corresponds to the schematic. This comparison provides an extra layer of certainty the completed PCB will function as intended in the original design. 




Impedance Modeling

Tighter Tolerance


Circuit Tech Inc. uses software from Polar Instruments and Frontline PCB Solutions InPlan to model a wide range of impedance requirements on a broad selection of laminate types. 

The demand for high quality controlled impedance continues to grow in speeds of modern PCB design circuitry. Current  PCB technology is not just simple electrical interconnection devices; they are highly complex, specific electronic components in their own applications. As the requirement of controlled impedance PCBs has increased, there has been a subsequent increase demand in requirements to verify these board designs prior to production. 

  • Differential Impedance PCB Structure
  • Single Ended Impedance Modeling
  • Microstrip and Stripline Constructions
  • Model soldermask thickness between and adjacent to tracks

High speed PCB performance designs require accurate controlled impedance traces to operate reliably 


Interconnect Stress Testing (IST)

What is IST Testing?

Interconnect Stress Test (IST) is an accelerated stress test method used to evaluate the integrity of the Printed Circuit Board (PCB) interconnect structure. It’s an objective test whose results are timely, repeatable, reproducible, and unique. Circuit Tech Inc. utilizes IST testing as a tool to measure the reliability and repeatability of our process. PWB Interconnect  creates a thermal cycle that stresses a specifically designed coupon, while simultaneously monitoring the electrical integrity of plated through holes (PTHs) and internal interconnects (Posts). It’s a test method that measures the integrity of different areas of the same structure — IST tests the PTHs and the Posts at the same time. IST automatically produces data that can help determine the PCBs ability to withstand the rigors of assembly, rework and the end use environment. IST gives a critical evaluation of a board’s quality and insight to the possible modes of failure. IST is an IPC approved (TM-650 2.6.26) test method; it’s experiencing rapidly growing acceptance by most major OEMs, CEM and PCB manufacturers as a definitive method for the measurement of PCB interconnect integrity. If you require confirmation of high long term reliability IST testing is your best choice.​
