Do you need to clean no-clean flux?
No, not if your concern is only reliability problems from ionic contamination. No-clean flux contains minimal ionic material that is fully consumed when the flux is activated, or in other words, brought next...

How do I clean flux off my motherboard?
The most common way to clean flux residues from a repair area is to saturate a cotton or foam swab with isopropyl alcohol or another cleaning solvent, and rub it around the repair area. While this may next...

What is flux remover?
Flux removers (defluxers) remove flux residues and other contaminants left by manufacture, rework, or repair of printed circuit boards. Flux removers can be solvent based (e.g. isopropyl alcohol) or water-based, next...

Should I worry about plastic connectors and components and rubber seals when contact cleaning?
While the contact surfaces of connectors are metal, they are often housed in plastic, and rubber gaskets to seal everything from the outside environment. If the solvent used in a contact cleaner is incompatible next...

What is dielectric strength?
Dielectric strength is defined as the maximum electric field that the material can withstand under ideal conditions without breaking down. Breaking down in this sense is described as a failure of insulating next...

Is it safe clean electrical contacts while the power is on?
There is no way to give a definite answer for all circumstances, because safety is highly dependent on the amount voltage and amperage as well as environmental factors such as the equipment, working environment, next...

Should a contact cleaner be nonflammable?
While it isn’t always necessary, a nonflammable contact cleaner would be the safest option if the vapors or liquid could be exposed to sparks, open flames, or hot surfaces. Of course, when the electrical next...

Is conformal coating conductive?
No, conformal coatings are non-conductive, or insulative. The job of conformal coating is to isolate the PCB or components from the environment and even components (i.e. high voltage or high heat) from next...

Is conformal coating waterproof?
While conformal coatings can offer a moisture resistant layer of protection, most cannot be considered waterproof. Even if applied heavily, most coatings are semi-permeable, so allow some amount of moisture next...

Is conformal coating necessary?
Whether or not conformal coating is required depends on the environment the electronic device will operate in, the reliability requirement of the device, and the cost of failure, whether in dollars or next...
