積層数も更に高多層化されることが予想されている。[Technical background of the invention and its problems] In recent years, the use of glass epoxy multilayer printed boards has rapidly increased in various computers, 0AII devices, microelectronic equipment, etc., and the number of laminated layers of multilayer printed boards themselves has also increased. It is expected that the number of layers will increase.

う欠点があった。Although such glass epoxy multilayer printed boards have various properties, they suffer from delamination due to moisture absorption. In other words, the multilayer board consists of ■Drilling holes→■Removal of copper foil from areas other than the circuit area by etching→■Through-hole plating→
A multilayer printed board is processed through the following steps: ■Solder coating → ■Component attachment → ■Soldering. After removing the copper foil, the multilayer board is processed by bath dipping in the through-hole plating process (■), and process (■). Moisture is absorbed by the humidity in the air between steps 1 and 2, and the humidity in the air between steps 1 and 2. The moisture-absorbed multilayer board is coated with ■ solder,
When soldering (2) is heated, moisture evaporates explosively, causing delamination of the board. Such a multilayer printed board has a disadvantage in that it cannot be used in terms of reliability.
