UV BUMP WITH PARALLEL BELT TRANSPORT

UV dryer for the double-sided UV cross-linking of solder resists.

Application:
UV cross-linking of photosensitive solder mask before or after thermal Final Cure for binding free photo initiators and improvement of the final properties of the solder resist.

PROCESS DATA
Photoinitiators in the soldermask required for UV exposure are partly cross-linked during exposure process. The UV cross-linking in the UV-bump links a large part of the excess initiators and improves the surface properties of the solder resist considerably in terms of solvent resistance, surface resistance, solderability and contamination.
Depending on the equipment a UV dose of 500 - to 4,000 mJ / cm ² is applied on the solder resist.
