Filed: 2000-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a hole by a carbonic acid gas laser suitable for manufacturing a high-density printed circuit board, and a method for posttreating after the hole is formed. SOLUTION: A method for forming a through hole and/or a blind via hole comprises the steps of mechanically cutting and exposing a surface layer copper foil on a target mark formed on an inner layer board of a multilayer copper-clad board, reading the mark by a CCD camera, directly radiating the carbonic acid gas laser of a high output suitably selected by 10 to 60 mJ from above a hole perforating auxiliary layer formed on a surface of the surface layer copper foil, and thereby removing the outer layer and the inner layer copper foil. The method for posttreating after the hole is formed comprises the steps of removing a burr generated at front and rear surfaces of the copper foil and the inner layer of the copper foil by etching and simultaneously partly melting to remove the copper foil of the surface layer in a thickness direction.  Thus, the through hole and/or the blind via hole can be perforated directly by the carbonic acid gas laser so as not to generate a hole forming fault even when the inner layer board is contracted.

Title: Communication system, and communication method
Inventor: YASUDA EIJI
IPC: H04L29/06
Filed: 2000-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce a time required for communication setting processing to match communication protocols or communication parameters. SOLUTION: The communication system is configured by interconnecting a computer PC acting like a terminal and a programmable controller PLC with a communication cable C. When the programmable controller PLC cannot receive data sent from the computer PC, a control section 11 of the programmable controller PLC returns data of its own parameters by using standard communication protocols. A CPU 1 of the computer PC revises its own communication protocol or parameters so as to be matched with the returned data. Then sending/receiving contents of the communication protocol or the parameters between the terminals (between the computer PC and the programmable controller PLC) can match the communication protocols and the parameters between both the terminals, and the time required for communication setting processing can be reduced.
