\"sierra proto express presents tomorrow\'s technology-today!\" tired of endless evolution? are you ready for a real revolution?
Now is the time for the US electronics industry to wake up from a deep sleep and re-emerge as the world\'s innovation leader in printed circuit boards.
It\'s time to look back.
It\'s time to raise expectations.
It\'s time to fundamentally rethink how PCBs are made.
Now is the time.
When others are processed due to old technical capabilities.
While others have a wait-and-see view of what new technologies are being adopted, we have taken a step forward.
While other PCB manufacturers are content to survive the downturn, we are reborn.
\"Once you turn this page, there is no way back.
High reliability board (Hi. Rel. )Our Hi. Rel.
The reliability of the printed circuit board is unparalleled, able to withstand more thermal cycles and higher temperatures than existing circuit boards.
This high reliability circuit uses proprietary plating technology to strengthen the copper in the hole and tolerate the expansion of the laminate during repeated thermal cycles. [
This breakthrough in reliability significantly improves the service life of the product.
The cost of replacing and repairing damaged electronics used by cracked vias is amazing.
Your company no longer needs to experience these board failures.
If you make an application for medical, space, aviation, transportation or any product that cannot fail, you need advanced protection from Hi. E. R.

The weakening of etching has distorted the shape of the track by 2-mils of cross-sectionalwidth.

Segment thickness of line width.
Our thin line technology is different.
Instead of using destructive etching, it uses a new platform technology to create thin lines.
The thinner the line, and more importantly, the narrower the space, the more important the plating accuracy is.
