Abstract:
A method for making the same is disclosed. First, a first substrate and a second substrate are provided. The first substrate includes a release film attached to a carrier. The second substrate includes a copper film covered with a solder mask. Second, the solder masked is patterned. Next, the release film and the patterned solder mask are pressed together so that the first substrate is attached to the second substrate. Then, the copper film is patterned to form a first pattern and a second pattern. The first pattern is in direct contact with the release film and the second pattern is in direct contact with the patterned solder mask. Later, a passivation is formed to cover the first pattern and the second pattern to form a circuit board structure. Afterwards, a package is formed on the carrier to form a packaging structure.
