IAg (Immersion Silver) PCB delivers smoother surface than HASL PCB. This kind of PCB surface finish is perfect for circuit in high density. Both interior and exterior copper thickness is 35um. PCB thickness is 1.8mm. Material option is FR-4. This PCB is often seen in military products.

With the commitment to environment protection, we especially introduce after-treatment liquid Ag86 for immersion silver surface. The liquid provides a protective layer on surface for isolation of air and material contacting. However, this layer brings no negative impacts on IAg PCB weldability and conductivity.
