The Underwriters Laboratory (UL) was set up around 120 years ago in the USA as an independent facility to test the safety of new products and new technologies. Today it has a network of sites around the world focused on product safety. It test products, certifies manufacturers, and produces and updates safety standards across a broad range of industrial and commercial sectors. For printed circuit...

Omni pcb will continue to monitor changes and additions for each of these regulatory statues and laws. We have been in contact with our suppliers and vendors regarding RoHS, REACH and Conflict Minerals requirements. All of them have responded with statements of conformance in regard to each. The following information is specific to providing our customers with RoHS compliant products. It outlines...

For high frequency analogue or digital circuits, it is essential to protect the signals that propagate on the PCB from being damaged. In fact, signals above 100Mhz are impacted by trace impedance which, if not properly taken into account, can cause unexpected errors that are especially difficult to analyse. Luckily, impedance control allows designers and PCB manufacturers to manage the phenomenon....

Testing the layer offset with X-ray technology is very important in the manufacture of multilayer circuit boards. X-ray images are the best (and only) way to identify and correct layer displacements in the pressing process. Drill holes in multilayer circuit boards are also optimized using X-ray images. Any minor deviations in the geometry of the circuit board image compared to the geometry of the...
