In the world of Materials & Processes, there are a lot more questions than there are answers.


Chem Logic participates in a Technical Forum on CircuitNet.com that focuses primarily on electronic manufacturing issues. Engineers with questions about very specific and intricate problems or processes, pose questions to others who are "in the know".


Here is a link to a summary of all of the answers that Rick Perkins of Chem Logic has provided through CircuitNet. You can also ask a question to the Technical Panel if you would so desire.

The U.S. EPA published this past week a notice in the Federal Register that it has begun promulgation of new regulations for the elimination of trichloroethylene (TCE) in several consumer and industrial products. The EPA is focused on uses in dry-cleaning as a spot-cleaner, aerosol formulations, and most importantly for the manufacturing sector, a ban on the use in vapor degreasing equipment.

Trichloroethylene has long been one of the key solvents used in vapor degreasing processes extending back into the 1930's when the vapor degreasing process came to light as one ...

Over the past 12 months, I have been pleasantly surprised with the new activity in high-reliability vapor-cleaning processes. Several companies, such as Baron-Blakeslee, are in the process of reinventing vapor degreasing as we once knew it.



The simple vapor degreasing process of the past is fading and new equipment controls and vapor controls are increasingly reducing solvent usage AND the chance of human exposure to the solvents, which is ALWAYS a "good thing" regardless of this year's chemical target list. No one wants to endanger their working employees.


And this is where I make my case against the continued use of "old, worn out" vapor degreasers. I have visited many companies and provide...
