Provided is a production method of an FRP precursor. The method includes: a pre-coating step of applying a resin varnish having a filler content of 5 vol % or less in a solid content thereof, to a sheet-shaped aggregate, and a melt-pasting step of melt-pasting a pair of resin films, each having a filler content of 30 vol % or more, to both surfaces of the aggregate, after the pre-coating step.

Method for producing FRP precursor

A layered plate including a copper layer having a thickness of 5 μm or less, and a resin layer provided on a surface of the copper layer, in which a water absorption rate of the resin layer is 1% or less after being left in an environment of 130° C. in temperature and 85% in relative humidity for 200 hours.

Layered plate and wiring base board production method

To eliminate or otherwise reduce unintended movement of a probe tip of a probe assembly being held by a probe arm, the probe assembly includes one or more resilient members that compensate for the contraction or expansion of the probe arm in accordance with the coefficient of thermal expansion of the material from which the probe arm is made. Thus, the probe tip can remain in contact with a sample being measured at the desired location on the sample, during an automated full or wide scale temperature range sweep.
