As PCB technology has continued to evolve, it has paved the way for the creation of a host of exciting product innovations. A prime example is the development of the PCB for LED lighting. The LED is soldered to the circuit board and features a chip that produces the light when electrically connected. A thermal heat sink and a ceramic base are used to bond the chip. An LED PCB board tends to genera...

High density interconnect PCBs are a way of making more room on your PCB to make them more efficient and allow for faster transmission. It's relatively easy for most enterprising companies that are using printed circuit boards to see how this can benefit them. High density interconnect (HDI) PCBs represent one of the fastest-growing segments of the PCB market. Because of its higher circuitry densi...

An increasing number of power electronics products are taking advantage of a growing trend in the printed circuit board industry: Heavy Copper and EXTREME Copper Printed Circuit Boards. Most commercially available PCBs are manufactured for low-voltage/low power applications, with copper traces/planes made up of copper weights ranging from 1/2 oz/ft2 to 3 oz/ft2. A heavy copper circuit is manufactu...

High-Tg PCBs are ideal to use in high-temperature requirements (>170 degree Celsius). Tg or Glass Transition Temperature defines the temperature limit for the proper working of PCB. To put it simply, the working temperature of the PCB should always be less than the Tg(glass transition temperature) value of the substrate. Tg affects the molecular weight, crosslinks, and flexibility of the polymer u...
