Abstract: The present invention relates to an improved anti-static computer assembly mat having multiple grounding points between the mat and other bodies capable of transmitting or receiving electrostatic discharge (ESD) during the assembly process. The grounding points may be connected to a computer chassis, a system builder, or a grounded outlet to ground the assembly mat and components thereon. The assembly mat has a relatively large assembly area such that a system integrator or builder may be able to place multiple components on the anti-static work surface at the same time while simultaneously preventing surface blemishes to system components. Further, the present invention provides for a wide variety of computer component measurements to assist the system builder in selecting and installing components during the build process. Such measurements may include rulers, motherboard sizing, CPU socket sizing, hard drive thread spacing, fan hole spacing, tubing size, power supply connectors, among other items.
