Our thanks to OK International for allowing us to reprint the following.

Why do we need fume extraction?
Today’s Electronics workplace contains numerous hazardous airborne substances, for example:

• Solder Fumes
• Adhesive Fumes
• Solvent Vapors

Solder Fumes
When solder flux is heated above 183oC, a complex mixture of resin acid particulates (smoke) and gases are generated – this is called “COLOPHONY” and is produced from:

• Hand Soldering
• Solder Pots and Fountains
• Wave Solder machines
• Reflow Ovens

Adhesives and Solvents
When using adhesives and solvents, vapors are produced, for example from:
