Printed Circuit Boards
The photoresists offered for PWB reflect detailed knowledge about processes and performance requirements in this competitive market. The resist enable the customer to manufacture the most challenging flexible circuits as required in medical applications. Our aqueously processable, liquid photoresists allow to coat boards in various sizes and with topographic features. The applied thin polymer film leads to high resolution and allows innovative designs which are not achievable with dry film technology.
APR 68 is a low cost etch resist for applying by roller-coating and formerly sold by Atotech Deutschland GmbH. This roller-coating combined with APR 68 is a cost saving alternative to dry film.
DiaEtch 300 is a liquid LDI etch resist. The resist has the ability to combine the advantages of Laser Direct Imaging with the resolution capabilities of a liquid resist. The wide processing window in developing ensures consistent and high yields. Specific rheological properties of this resist lead to the best possible thickness distribution when applied by dip-coating. The product can be used as etch resist for thin inner and outer layers.
