Printed circuit

Introduction

This book is a training material designated by the Printed Circuit Technology Department of the Production Technology Credit Branch of the Chinese Institute of Electronics. The book consists of 15 chapters, divided into three parts: the first part (chapters 1 to 9) mainly introduces the printed circuit board materials and various processing techniques; the second part (chapters 10 to 13) focuses on the rigid multilayer printing Board production technology, high-density interconnection build-up multilayer board technology, flexible and rigid-flex printed board production technology, metal-based (core) printed board and other printed board production technologies; Part Three (14, Chapter 15) introduces printed circuit technical specifications, inspection and water treatment technology and environmental protection.

This book can be used not only as a training material for highly skilled personnel in the printed circuit, but also as a reference book for practitioners in the printed circuit industry and related professional teachers and students.
