Non-Contact Measurement of Conformal Coating Thickness
Conformal coating is designed to provide protection and long-term reliability to printed circuit boards (PCB) in harsh environments where high humidity, high temperature, corrosive gases, or salt spray may be present. This study aims to highlight the application of chromatic confocal microscopy (CCM), an optical technique used to characterize 2D/3D surfaces.

3D Aerosol Jet Printed Interconnects on Bare Die
Aerosol Jet Printing can provide many enhancements over traditional bare die attachment techniques. Previous studies have shown that AJ technology offers advantages in the millimeter wave frequency range, such as a significant reduction of insertion loss and the ability to design the line impedance as required.

Can Silver Cause Solder Embrittlement?
A few of our components have leads with a silver finish. Will silver cause solder embrittlement? Is removal of silver needed or can it be soldered using 63/37 solder? Phil Zarrow and Jim Hall, The Assembly Brothers, discuss this question and scenario.

Non-Contact Measurement of Conformal Coating Thickness
This study aims to highlight the application of chromatic confocal microscopy (CCM), an optical technique used to characterize 2D/3D surfaces. In this work, conformal coating wet and dry thicknesses were measured using CCM and traditional methods. FR4 boards with varied color solder masks and components were created for realistic use cases.
