Connectors and printed circuit boards are important components in all electronic products, both of which are complex electronic devices. The electrical characteristics of connectors and PCBs can not be ignored in circuit designs for many applications. The technical and commercial requirements for these two electronic devices have increased considerably in recent years. Cost and performance optimization of electronic components The design requirements are the exact knowledge of the process and commercial characteristics of connectors and printed circuit boards. In the two seminars will mainly talk about connectors and printed circuit board of the main technical reasons for failure, quality requirements and two components of the cost factor.

Connectors are used in all electronic products: eg industrial electronics, consumer electronics, automotive, telecommunications, medical or traffic engineering. The course is dedicated to practical applications including materials, connection theory and the basis for electrical engineering, as well as for circuit boards and cables Various connection techniques, condition tests and different types of connectors are required for different causes of the error.

Printed circuit board requirements have undergone considerable changes in recent years. Printed circuit boards are no longer just wiring support components for electrical components, but rather an independent, complex component. The electrical and thermomechanical properties of printed circuit boards are therefore an important consideration in the design of electronic components and systems. In addition, PCBs are exposed to high-stress mechanical stress treatment and use of lead-free solders, for example in the automotive sector, Extreme environmental conditions. In addition, the production of printed circuit boards on the market is subject to high cost pressures.
