EMI Interference: Understanding and Mitigating AC and DC Magnetic Fields
October 17, 2019DC and AC magnetic fields create electromagnetic interference (EMI) that can degrade the performance of electron microscopes and e-beam lithography tools. Although AC and DC magnetic fields are related, each impacts equipment differently. There are different strategies to mitigate both, but an AC+DC active magnetic field cancelation system is often the simplest and most cost-effective […]

Understanding and Mitigating The Vibration In Your Facility
August 27, 2019Low-frequency and high-frequency vibration both have a significant impact on electron microscopy laboratories and high-tech manufacturing facilities. These two types of vibration stem from different causes and the strategy for mitigating vibration for each is also different. Vibration Engineering Consultants (VEC) can help you quantify and identify the vibration in your facility and work with […]

Why Use a Third-Party for Your Site Survey
July 16, 2019A new microscope and semiconductor customers have a few options when it comes to deciding who should provide their site survey. The original equipment manufacturer (OEM) will often offer the survey; organizations sometimes attempt to conduct the surveys themselves in-house. In this post, we explain why a third-party site survey provides considerable benefits and is […]

DC Field Disturbances on Electron Microscopes and E-Beam Lithography Tools
January 24, 2018Overview: Changes in DC magnetic field levels near an electron microscope or e-beam lithography tool degrade image quality and inhibit production. A change in DC fields often results in image distortion, a blurred image, or image drift. Common sources of change in DC fields are variation in the Earth’s magnetic field and the movement of […]

Why a Site Survey is Import
November 21, 2017Let VEC help you make informed decisions and protect against unwanted surprises Overview: Site surveys are a critical requirement whenever purchasing new tools or moving into a new laboratory or clean room. Site surveys both help determine if your space meets manufacturer specifications and if additional preparatory work is required. This could be the replacement […]

Reducing Vibration from Mechanical Equipment in an Electron Microscopy Lab
November 21, 2017Discussion: Reducing Vibration from Mechanical Equipment in an Electron Microscopy Lab: Laboratories often have vibrating equipment that causes disturbances on electron microscope images. These sources include chillers, vacuum pumps, transformers, etc.. At VEC, this is a problem that we commonly see in our clients’ laboratories. Following some basic guidelines can help reduce the impact of […]
