For decades, HumiSeal products have been considered the “gold standard” in electronics protection. As a result, it is no surprise that unscrupulous chemical manufacturers have been continuously trying to profit from this reputation through the production of copycat or counterfeit products. While imitation is considered the sincerest form of flattery, the use of counterfeit materials is a...
For many electronics manufacturers, the original justification for specifying a silicone coating is lost deep within the mists of time and it may be time for a re-evaluation and consideration of the question,
“Do we really need a silicone conformal coating?”
Humiseal® remains in a uniquely qualified position to help you answer this question. Unlike many coatings sources, Humiseal offers a full...
IPC CC-830 revision B is a conformal coating qualification standard mostly used by board fabricators, OEM design engineers, and coatings suppliers.
There are two fundamental uses of this IPC standard:
- Coatings’ performance capabilities
- Quality consistency
In this blog, we will go over some of the specifications along with tests requirements, passing criteria, and quality characteristics.
The conformal coating process, like any other processes, has different variables, inputs, and outputs. In order to be able to control the results of your application (outputs), we need to fully understand how each variable affects the process.
The importance of the variables
To get the right amount of liquid, thickness, right coverage, no contamination on keep out areas, etc., you need to...
When conventional coating methods such as hand spray, total dipping or robotic selective coating don’t provide the protection required, there is always selective dip coating.
What is selective dip conformal coating?
Selective dip coating is a process whereby the substrate rather than globally immerised in the coating, is discreetly coated in desired locales. The technique in one form or...
The application of the conformal coating in a uniform and consistent coverage is a key challenge that defines the reliability of the finished product.
A thin coating will provide inadequate protection against corrosion or insulation between conductors. Conversely, if the conformal coating is too thick, it will increase the risk of forming other types of coating defects such as bubbles,...
One of the basic components used in most automatic or semi-automatic conformal coating processes is compressed air. Pressurized air moves the liquid coating from the tank, through the hoses and the valves onto the PCB. Since the pressurized air makes direct contact with the conformal coating, there are critical properties that must be taken into consideration, especially with moisture...
This blog post outlines the techniques required for the removal of HumiSeal UV cure conformal coating. The products covered in this article are:
- UV40, UV40-250
- UV500, UV500LV
There are 3 methods for the removal of HumiSeal UV conformal coatings:
- Mechanical removal: Powder Micro Abrasion
- Thermal removal: Burn Through
- Chemical removal
All three methods will effectively remove the...
ENERGY STAR, The United States Environmental Protection Agency program that provides certification to buildings and consumer products which meet certain standards of energy efficiency, defines what a LED light is.
LEDs, or light-emitting diodes, are semiconductor devices that produce visible light when an electrical current passed through them. LEDs are a type of Solid State Lighting (SSL),...
