 What is RoHS?
     RoHS is the acronym for Restriction of Hazardous Substances. RoHS, also known as Directive
 2002/95/EC, originated in the European Union and restricts the use of specific hazardous materials
 found in electrical and electronic products. All applicable products in the EU market after July 1, 2006
 must pass RoHS compliance.  Read more…
 What is IPC?
    IPC was founded in 1957 as the Institute for Printed Circuits. As more electronics assembly
 companies became involved with the association, the name was changed to the Institute for
 Interconnecting and Packaging Electronic Circuits. By the 1990s, most people in the industry could
 not remember the full name and/or didn't agree on what the words in the name meant.

Ticer Technologies Embedded Resistor Calculator
  This downloadable resistor calculator is a tool used by printed board designers to select sheet
 resistivity while considering resistor size, shape and power handling capability. The tool can help
 the designer select one or more of the available TCR ohms per square sheet resistance values to
 capture and eliminate more surface mounted resistors. It also has an input for etch factors, which
 allows designers and fabricators to better predict the final tolerance of the finished resistor. The
 calculator is available in both metric and imperial (inch) formats. Click to Download
