Abstract

This invention provides a method of spray coating blind vias, especially applicable to multi-layer BGA and CSP printed circuit boards. Under this invention, target via area is first vacuumed to remove all air content, and then completely spray coated with filling materials thus increasing the reliability of electronic products manufactured with this process.
