What does 2-step curing mean?

That just means you break the accelerated curing process into 2 stages. You basically ramp up the heat so the coating has an opportunity to level. Otherwise, you can get a wrinkling or orange peel texture. next...

Does your lotion contain benzalkonium chloride (BZK)?

Zero Charge Hand Lotion does not contain benzalkonium chloride (BZK). next...

Can temporary solder mask be left on the PCB permanently?

Temporary solder mask is intended to be just that – temporary. Manufacturers of solder masks, like Chemtronics, always recommend removing the mask because there is no testing to support doing otherwise. next...

How can you reduce chemical exposure?

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 next...

How do you know the safe exposure limit of a degreaser, contact cleaner, or flux remover?

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 next...

What is the difference between dielectric strength and dielectric withstand voltage?

The dielectric strength is material intrinsic property and withstand voltage is surface property which depend on thickness of the material. They can be slightly different for thicker materials, but for next...

What type of UV light / black light should I use for QC inspection of the final conformal coating?

Conformal coating with UV tracer can be inspected with any typical UV lamp which has wavelength of 320-380 nm. next...

What solvent can I use to thin this conformal coating?

Toluene or acetone can be used as a thinning agent. Make sure it is anhydrous, so contains as little moisture as possible. next...

What Is the Best Cleaning Solvent for an Ultrasonic Process?

If the chemistry is a good solvency match to the soil, less sonic agitation will be needed. This allows you to run your cleaning process more quickly, at lower temperature, and lower amplitude, decreasing next...

How Do You Maximize Cleaning Performance with Ultrasonic Equipment?

Several adjustments can be made to increase the cleaning performance of your ultrasonic process: 1) Frequency – This is the number of waves in a second, so how “tight” the wave form is. next...
