Adhesive Solutions on PCBs

The continuing trend towards miniaturization of PCBs (printed circuit boards) presents the challenge of ensuring that, despite their ever decreasing size, contacts and components continue to work reliably. Many soldered joints on PCBs are therefore being replaced with more flexible electrically conductive adhesives. To protect sensitive components, adhesives are applied to PCBs as glob tops, coatings or underfills for chips. Panacol offers a wide range of adhesives for these applications that meets the various market requirements.

Flip Chip Underfill

Underfills are used for mechanical stabilization of flip chips. This is especially important when soldering ball grid array (BGA) chips.
