  • Printed circuit boards: A mobile market

    2014-10-1u2002·u2002PCB environmental concerns: Hits and misses. Efforts to eliminate substances deemed environmentally unfriendly by consumers have already had a significant impact on the printed circuit board (PCB) market. One result is the move to lead-free solder. Another is replacement of brominated fire retardants (BFRs).

  • PCB Line Spacing for Creepage and Clearance

    2020-12-11u2002·u2002CTI values help to deduce the overall PCB tracking resistance. These values give an estimation for leakage or short-circuit as trace spacing becomes small due to component density. As per the IEC-60112 standard, a higher CTI grade substrate offers good resistance to electrical breakdown. CTI is a critical number while selecting a PCB material.

  • Designing to PCB Creepage and Clearance Standards in ...

    2021-5-3u2002·u2002Creepage: This is the distance between two conductors on the surface of the board, or along the surface of insulating material. Clearance: This is the line-of-sight distance between two conductors through the air. In high voltage circuits, where the voltage is above 30VAC or 60VDC, creepage and clearance spacing rules must be observed to ...

  • DIY Lab Equipment: How to Etch Your Own Circuit Boards ...

    2012-5-4u2002·u2002Homemade circuits are amazing. You can build any kind of circuit on a simple perfboard, as we have seen in previous projects. However, some projects require very tiny circuit boards. We could special order some boards from a printed circuit board (PCB) factory, but that will most likely involve a high price per board and a few thousand miles of delivery service to pay for.
