I'm going to discuss toxicity issues with some classes of solvent cleaners, and how you can make the best decisions to keep your workers safe and healthy. There is increased interest in this topic because of the EPA’s recent statement...

The US Environmental Protection Agency (EPA) has determined that n-propyl bromide (aka. nPB, 1-Bromopropane, 1-BP, CAS 106-94-5) “presents an unreasonable risk for 16 conditions of use” in an August, 2020 report. “Nontechnical...

CASE STUDY: Fiber Optic Connector Failures at a Waste Incineration Plant At Chemtronics, we offer cleaning solutions for the messiest problems, and it doesn’t get messier than a waste incineration facility. You may not realize this, but...

Running cable can be a messy business, so cleaning is an important consideration for both high voltage and communication cable installations. When the failure point can be in a wall, underground, or hundreds of feet underwater, a high-quality...

Download Defects Guide PDF To consistently and repeatably conformal coat PCB's, all the variables need to be controlled like heat, humidity, time, contamination... and the list goes on and on. Failure to control your process can result...

Every organization using hazardous chemicals within their facility has the responsibility to equip their facility and personnel to maintain exposure levels below the TLV. Personal monitoring badges can be used to measure exposure of a specific...

The personal hazard associated with a solvent is often defined using Threshold Limit Value (TLV), which is the recommended average exposure in an 8-hour day, 40 hour work week. The lower the TLV of a particular substance, the less a worker can...

What is Temporary Solder Mask Temporary solder mask (also called “spot mask”) is used every day in the assembly of electronic circuit boards. Solder mask is engineered to protect thru-holes or “vias” in wave soldering....

Diagnosing and repairing electronics can be painstaking and sometimes frustrating work. Problems can be intermittent, with the faulty area on the PCB difficult to locate. Freeze spray is an essential tool, because it helps identify faulty components,...
