Impedance Control PCB Assembly
NOD Electronics has many years of experience producing PCB and low-quantity production runs with short lead times for many different types of applications.
In order for a PCB manufacturer to properly execute an order, it needs a set of exact sizes and coordinates, trace widths, hole patterns and, of course, tolerances. PCB Impedance is the sum of reactance, or the AC component, and resistance, or the DC component of an electric circuit. PCB manufacturers are expected to conform to the PCB trace impedance values and tolerances specified by the designer in order for the board to behave as desired.

Impedance Control PCB Assembly Process Control
NOD Electronics fully show respect to your strict confidentiality of documentation and procedures and has formalized a range of control process that can ensure customer products in delivery of good quality. We will operate the process during Incoming Quality Control (IQC), In-Process Quality Control (IPQC), Outgoing Quality Assurance (OQA) etc stages and management methods ISO, 7 sigma, PDCA.
For more critical applications you will need to specify “controlled impedance” and supply the actual impedance requirements for the conductors and we will fine tune the dielectrics and conductors to meet these requirements. The impedance requirements will have to be specified based on the layer and the conductor widths.
