Image PCB copper pour hatch filled.png thumb right 250px Copper pour is sometimes filled using a hatch fill style. In electronics, the term copper pour refers to an area on a printed circuit board filled with copper the metal used to make connections in printed circuit boards . Copper pour is commonly used to create a ground plane . Another reason for using copper pour is to reduce the amount of industrial etching etching fluid used during manufacturing. A distinctive feature of copper pour is the backoff or stand off a certain distance between the copper pour and any tracks or pads not belonging to the same electrical net . A copper pour therefore looks like it flows around other components, with the exception of pads which are connected to the copper pour using thermal connection s. While solid copper pour provides better resistive characteristics, hatched copper pour is used to balance the heat and dilatation on both sides of the board in order to avoid warping of certain substrate. ref cite web url http www.electronicspoint.com copper pour traces t72199.html post message 556731 title Copper pour or traces? publisher electronicspoint.com date 2007 08 01 accessdate 2011 08 31 ref Heating might cause gas bubbles between solid copper pour and certain substrates. ref cite web url http forum.allaboutcircuits.com newsgroups viewtopic.php?p 8563 8563 title PADS hatch vs pour publisher allaboutcircuits.com date 2003 09 20 accessdate 2011 08 31 ref Furthermore it might be possible to adjust the impedance of high frequency traces by using hatched copper pour in order to reach better signal quality. ref cite web url http electronics.stackexchange.com questions 5139 solid ground plane vs hatched ground ... date 2010 10 12 accessdate 2011 09 01 ref References references DEFAULTSORT Copper Pour Category ... more details

notability date March 2009 Orphan date February 2009 Heavy Copper PCB The Printed Circuit Board Printed circuit board PCB industry defines heavy copper as layers exceeding 3 ounces of copper, or approximately 0.0042 inches 4.2 mils of copper thickness. PCB Designers and Fabricators often use heavy copper when design and manufacturing circuit boards in order to increase current carrying capacity as well as resistance to thermal strains. Heavy copper plated vias transfer heat to external heat sinks. The IPC 2152 is a standard for determining current carrying capacity in Printed Board Design. The task group was chaired by Michael R. Jouppi. An ounce of copper thickness on a PCB is defined as the thickness of one ounce weight of copper rolled out to an area of one square foot. An ounce of copper is approximately 1.4 mils 0.0014 inch or 35 um of thickness.
