‘Conformal coatings for electronic circuit protection’ - .PDF file.

Intertronics has released its Dymax Dual-Cure 9482, a UV light- and moisture-cure conformal coating specially formulated to flow underneath components on printed circuit boards (PCBs) and to cure in these shadowed areas by using ambient moisture, which can result in faster throughput for through-hole assemblies.

According to the company, the Dymax 9482 coating demonstrates excellent ‘re-workability’, which is of particular importance to manufacturers of expensive PCBs or manufacturers looking to increase board yields.

The 9482 coating features a vivid blue fluorescence when exposed to UV light, which enables the obvious detection of coating presence before and after cure. In addition, it was developed to be tack free immediately after curing, helping to avoid defects such as fingerprints that may be left on the boards if they are handled too soon.

Dymax 9482 is engineered to provide excellent circuit protection in applications requiring coating thicknesses up to 0.25mm. Typical applications include electronic assemblies for the general and consumer electronics, automotive, appliance and military equipment manufacturing industries.
