An electronic control unit (7) includes a conductor board (12) made of a flexible substrate and defining at least one conducting path of the conductor board (12). A basic body (11) is made of a conductive material and disposed in substantially close contact to the conductor board (12) and defines a flat projection of the basic body (11) onto which the flexible substrate is fastened such that a basic-body-conductor-board unit is formed before the conductor board is assembled with at least one electronic component (16). The basic-body-conductor-board unit is re-shaped into a desired geometry after the assembly of the conductor board (12) with the electronic component (16). A method produces the basic-body-conductor-board unit.

Abstract:
There is provided a laser processing apparatus, a multilayer printed wiring board manufacturing apparatus, and a manufacturing method to form via holes of ultra-fine diameter. The laser beam from the CO2 laser oscillator (60) is converted to the shortened wavelength beam by a tellurium crystal (94) to control diffraction of the laser beam. Simultaneously, when the laser beam is condensed, a limit value of the condensation limit is reduced. Thereby, the spot diameter of laser beam is reduced and a hole for via hole is bored on the interlayer insulation resin on a substrate (10). Therefore, even when the laser beam output is raised to form a deeper hole, the hole diameter is not widened and thereby a hole for a small diameter via hole can be formed.
