Leading the way for over 40 years
Mermar Electronics has many years of experience in manufacturing impedance control PCB. As the requirements for quick signal speeds in circuit boards rise, there is an added need to work on ensuring the best signal integrity. One of the areas that requires focus in design is controlled impedance traces. There needs to be a carefully created trace structure that ensures there aren’t any differences in impedance that can distort the signal. Matching the impedance of PCB traces, therefore, is important as it helps maintain data integrity as well as signal clarity.
Essentially, controlled impedance refers to the matching of substrate material properties with trace dimensions and locations. This ensures that the impedance of a trace’s signal is within an acceptable range.
Controlled impedance boards offer high frequency performance. If, on the other hand, the impedance of the PCB trace connecting two components does not match the components’ characteristic impedance, there may be an increase in switching times within the device or the circuit.
Typically, PCB trace impedance can range from 25 to 125 ohms. The impedance value generated from the PCB structure is determined by the following factors:
- Width and thickness of the copper signal trace.
- Thickness of the core or prepreg material.
- Dielectric constant of the core and prepreg material.
- Distance from other copper features.
At Mer-Mar Electronics, we have over 40 years of experience in offering high quality PCBs. Armed with state-of the-art technology, experienced professionals and industry best practices, we ensure that the trace impedances and their tolerances are checked early on in the design since uncontrolled impedance is difficult to analyze once the components are mounted on the circuit.
Our controlled impedance PCB design and manufacturing services ensure that you do not have to face any issues when it comes to signal integrity. We work with your team at the PCB design stage itself to help you control impedance by selecting the right material as well as layer stack up.
Our controlled Impedance PCBs are manufactured using the latest material as well as technology. We also undertake stringent Incoming Inspection for laminates, prepreg and copper foil.
The use of LDI (laser direct imaging) equipment eliminates any variances in trace width. The etch process is smoothly managed to make sure that we meet the impedance tolerance limits.
You can rest assured that we conduct robust tests to ensure that we achieve the desired impedance using TDR coupons.
