UNDERFILL

Typical Application

Underfill provides shock, drop, and vibration protection for electronic devices. PROTAVIC offers a range of capillary underfills, suitable for protection of CSP’s, BGA’s and flip chip components.
Underfills improve the reliability of the solder connections, specifically under thermal stress and/or drop testing. Thermal stresses due to CTE mismatches are overcome, thanks to underfill encapsulants.

DAM/FILL & GLOB TOP

Typical Application

Dispensing a high-viscosity dam followed by a low-viscosity fill, will create a completed encapsulated package for your CSP, BGA and/or other semiconductor component. Dam- and-Fill materials improve the reliability of the package, and help in reducing warpage. As such, the components will resist to physical thermal stress, as well as improve resistance against moisture and chemicals.

Glob Top encapsulants have the same purpose as Dam & Fill materials. Where Dam & Fill encapsulants are typically used for larger die applications, Glob Top encapsulants are used in case of smaller chips. Our range covers materials with high Tg and low CTE.

COATING, ENCAPSULANT AND POTTING COUMPOUNDS APPLICATIONS

Typical Application
Potting compounds are pourable insulating resins (epoxies, silicones, urethanes and hybrids) to be cast into cavities containing electronic components to insulate, protect, and hold them in place thus protecting components from shock and vibration.

Sensitive components on PCB’s require protection against external factors such as humidity, dust, chemicals, etc. Also LED assemblies require potting compounds, which require resist yellowing in harsh environments such as UV exposure, heat, etc.

PROTAVIC offers UL94-V0 flame retardant materials, based on different chemistries (polyurethane, epoxy, silicone, acrylics). In addition, a range of UV-curable, solvent-free coatings have been developed suitable for high temperature applications.
