Fume Control for Conformal Coating PCBs

Fume Control for Conformal Coating PCBs

Conformal coating is a process that is used to protect electronic assemblies from environmental damage and corrosion. It is often applied to PCBs (printed circuit boards) to keep them functioning in high-temperature or corrosive environments. Fume control is an integral part of the conformal coating process, as the fumes created by the coating can be harmful to workers and equipment.

Fume extraction systems reduce the risk of exposure to hazardous chemicals and ensure a safe working environment. They capture the airborne pollutants created by conformal coating processes, such as volatile organic compounds (VOCs), solvents, and other dangerous particles.

We will discuss the benefits of fume control for conformal coating PCBs.

What Is Conformal Coating and What Are the Hazards?

Conformal coating is a protective layer for printed circuit boards (PCBs). It helps to reduce the corrosion of electrical contacts and provides an insulation barrier. The coating also prevents contamination, dust, dirt, moisture, fungus, and other hazardous substances from entering the components of the PCB.

When the conformal coating is applied, it can create an air-borne hazard due to the release of volatile organic compounds (VOCs) and other hazardous substances. These VOCs can linger in the air and pose a health risk to workers exposed to them for extended periods. Additionally, some coatings may contain hazardous substances like isocyanates or hexavalent chromium, which pose a risk even at low exposure.

Benefits of Proper Fume Control

Proper fume control is essential in PCB conformal coating applications, as fumes can be dangerous to the health of personnel and nearby machinery. Here are the benefits:

1) Improved worker safety:

PCB conformal coating is safer for personnel with proper fume control. This includes reducing the risk of inhalation and contact with dangerous fumes.

2) Reduced production downtime:

Without proper fume control, fumes can build up in a work area and cause machinery to malfunction or be damage by corrosive agents. Proper fume control helps eliminate downtime due to fume-induced malfunctions.

3) Lower maintenance costs:

With proper fume control, personnel does not need to wear protective gear and respirators, which saves money on purchasing and maintaining such equipment.

4) Less environmental impact:

Fumes from PCB conformal coating applications can be damaging to the environment if not properly contained. Proper fume control helps to reduce the impact of PCB conformal coating on the environment.

How Does Fume Control Work?

Fume control works by trapping and removing the fumes generated during PCB conformal coating applications. This can be done through various methods, such as using ductless fume hoods or enclosure systems containing the fumes in an isolated area. Additionally, some systems use filtration to trap and remove airborne particles from the air before they can affect personnel or the environment.

When setting up PCB conformal coating production lines, it is essential to consider the type of fume control used and any safety protocols and procedures that must be followed to ensure proper operation.
