Cleaning Technologies – Trends and Developments

Tags: Safewash, Electronic and General Purpose Cleaning, Cleaning

Cleaning is an essential process within electronics manufacture and has been used for many years to remove potentially harmful contaminants during PCB manufacture. Such contaminants include flux, solder and adhesive residues, and other more general contaminants such as dust and debris present from other manufacturing processes. The purpose of cleaning, specifically within the rapidly expanding electronics industry, is to essentially improve product lifetime by ensuring good surface resistance and by preventing current leakage leading to PCB failure.

Conformal Coating Standards – Protection in Harsh Environments

Tags: Conformal Coatings

The electronics industry is one of the most rapidly expanding industries to date, with endless research and introduction into new applications. Printed circuit boards (PCBs) are found in many domestic, industrial, automotive and military devices, to name but a few. In most of these applications, reliability is essential, even when the device may be subject to harsh conditions such as high humidity, corrosive atmospheres or high levels of dust or contamination. Conformal coatings can be utilised to protect the PCBs from such environments, ensuring optimum performance under the toughest conditions. They are applied as thin films, typically ranging from 25-75µm, and conform to the contours of the board, providing maximum protection with minimum weight or dimensional change to the PCB. This is one of the primary advantages of conformal coatings, particularly with popular trends in miniaturisation and portable devices. Read more >
