Application Notes—Analog Optical Isolators

The best policy is one which prevents tarnish from forming. Tarnish,

which is a compound formed when silver reacts with sulfur (Ag2S), can

be prevented by keeping the components away from sulfur or sulfur

compounds. Since two major sources of sulfur are room air and paper

products, it is best to store the devices in protective packaging such as

a “silver saver” paper or tightly sealed polyethylene bags.

After soldering, it is necessary to clean the components to remove any

rosin and ionic residues. For a listing of recommended cleaning agents

please refer to Application Notes #3.

APPLICATION NOTE #3

Recommended Cleaning Agents

The construction of an AOI consists of a cast epoxy LED, ceramic

photocell, a molded case and epoxy as the end fill. This construction

allows a wide variety of cleaning agents to be sued after soldering.

In many cases the devices will be exposed to a post solder cleaning

operation which uses one or more solvents to remove the residual

solder flux and ionic contaminants. Only certain cleaning solvents are

compatible with the plastics used in the AOI packages.

This listing of recommended/not recommended solvents represents

only a very small percentage of available chemical cleaning agents.

Even with this list of recommended solvents it is important to be aware

that:

Solvent exposure times should be as short as possible.

The exact requirement of the cleaning process will vary from

customer to customer and application to application.

Additives and concentrations will vary from supplier to supplier.

Because of these uncertainties, our recommendation is that all

customers carefully evaluate their own cleaning process and draw their

own conclusions about the effectiveness and reliability of the process.

PerkinElmer cannot assume any responsibility for damage caused by

the use of any of the solvents above or any other solvents used in a

cleaning process.
