Bonding Solutions for Mini Camera Systems

Modern vehicles have a large number of miniature cameras: Rear view cameras help when parking and reversing, driver assistance systems support when changing lanes or other driving situations, other cameras help with traffic sign recognition, to name just a few examples. These mini cameras are embedded in the body and are so small that they cannot be bolted into place: Instead, special adhesives adapted to the respective materials are used to bond the plastic housings and fix the lenses. Panacol offers a range of product solutions for this.

Active Alignment

Active Alignment involves fitting lenses into the camera body and adjusting the focus. As soon as the position of the lens is exactly right, the adhesive is cured in a fraction of a second using UV light. The demands on the adhesive are high to achieve high-precision bonding: Not only must the adhesives cure very quickly, they must also have low water absorption and low and reproducible shrinkage to avoid tension. 

Bonding of Housings 

Camera housings consist of many individual parts that must be glued together. For this purpose, adhesives are used which have a high adhesion to the substrates to be bonded and which also seal the camera against dirt, dust and moisture.

Lens Bonding

In complex camera systems several lenses are used. In order to fix these lenses in a space-saving way, they are glued to each other. The adhesive must not only be extremely transparent and non-yellowing, but also scratch-resistant and resistant to moisture.

Only with adhesives can the small camera systems be securely joined
