Since you used the term "board" I assume you are referring to an outerlayer or double sided application rather than an innerlayer application. You can mechanically scrub the board using bristle brush or compressed pad type scrubbers, or jet or brush pumice type scrubbers or jet Alumina oxide scrubbers. Hand pumice scrubbing is also an option for low production level situations and is common for flex applications. You can also laminate photoresist directly over an unscrubbed electroless surface with appropriate rinsing and pH neutralization after electroless and perhaps an antitarnish treatment depending on hold time requirements. Direct metalization systems require a microetch in most cases to remove the deposit from the surface copper but this usually provides an adequate surface for photoresist lamination as well. There are additional options if you are including acceptable surface preparation methods for innerlayer applications. Hope this helps.
