Customer Success
Merit of EMIStream
1. Reducing Iteration Process
2. Filtering Design Errors Before EMC Engineer Evaluates Prototype PCB
EMIStream V4 is improved with powerful features for non EMC expert. It indicates priority order to fix the problems in error list and gives advice how to control EMI problems on your PCB design.
Now EMIStream V4 produced EMC Expert Option for EMC professionals. It does not only enable you to customize threshold value and in-depth parameters, but also take into account both far-field calculation and multi-layer plane structure in order to obtain more accurate result.
Sample Effects
User Background
This user's product was a phone switchboard for a German company. Major expenses included having several shipments from Japan to Germany to get certification at their test site in their local chamber.
Effect1. Cost Saving
Cost effective approach by reducing iteration process on design/test and the number of components for EMI suppression.
Before Using EMIStream
Site test
- Once in 3wks, repeat 2 or 3 times (aprox.$150,000)
Time of re-routing design
- 2 to 3 wks+ Prototype creation
Costly solution by chassis, filter
- Abt. 30 filters/ One board (Aprox.$5) Shipping Products: 1,000 sets x 8 boards = aprox. $40,000
After Using EMIStream
| Site test | One time only ($50K) |  |
| Time of re-routing design | Few days + Prototype creation |  |
| Costly solution by chassis, filter | Reduced the number of filter |  |
Effect2. Time Saving for Evaluation and Countermeasures
Shorter evaluation and countermeasure time for EMI problems by reducing the time of prototype PCB creation
The figures are a before and after comparison using EMIStream. The product is a hard disc copy device. (Actual data) The left figure shows results before using EMIStream and voltage is upper VCCI regulation at 350MHz and 700-900MHz. The right figure shows results after using EMIStream. From 30MHz to 1 GHz, voltage is below VCCI regulation.
In this product case, the customer could reduce solution components costs to 1/10 after using EMIStream. Evaluation and times for EMI suppression which used to take 10 days, now only takes 3 days after using EMIStream.
