Via Dep® 4550
Electroless copper system for difficult-to-plate substrates, offering superior adhesion while maintaining structural integrity.
Contact UsProduct Overview
Via Dep® 4550 electroless copper system is specially designed for difficult-to-plate substrates. The 4550 process offers superior adhesion on inert surfaces and difficult structural designs while maintaining structural integrity. The zero-stress, blister-free deposit for Semi-Additive Process (SAP), Modified Semi-Additive Process (mSAP), and flex applications ensures metallization needs on complicated hybrid devices can be met with ease. Via Dep 4550 H is formulated for horizontal lines.
Product Features
Stress Free Copper Deposit
Via Dep 4550 passes IPC-TM-650 thermal stress testing for plated through-holes.
Enabling Difficult-to-Plate Substrates
Compatible with flex, rigid-flex, and rigid Printed Circuit Board (PCB) designs for complex hybrid devices.
Delivering Operating Cost Efficiencies
Via Dep 4550 operates at low temperatures, enabling reduced operating costs. The system is also a drop-in replacement for existing electroless copper lines.
Consistent Deposit Across a Wide Operating Window
In the production environment, yields are becoming increasingly important due to the growing electronics content in automotive, medical, and consumer devices. The Via Dep 4550 process provides the same highly adherent deposit, whether processed with fresh chemistry, at high or low temperatures, or over a wide range of materials.
Adhesion on a Wide Range of Exotic Materials
Conventional electroless copper baths lack the superior adhesion provided by Via Dep 4550. A proprietary formulation enables high-performance metallization on flex, rigid-flex, and rigid PCB materials, meaning that only one bath is needed for a large number of jobs.
SAP, mSAP, and Flex
Zero-stress, blister-free deposit for SAP, mSAP, and flex applications on complex hybrid designs.
