For Production of reliable PCBAs

To have in mind for production and ordering of reliable

PCBAs with the

assistance of IPC Standards.


IPC is a global association that continually develops and publishes the world’s most widely used quality standards for electronic production of bare boards plus circuit board assembling and soldering.

Tallinn Polytechnic School (Tallinna Polütehnikum), IPC’s Training Center in Estonia, organizes and invites you to an informative and entertaining seminar in Estonia held by Mr. Lars Wallin, IPC’s Europe Representative. The seminar has been very much appreciated by thousands of attendees active in the electronic hardware production chain in many European countries. The presentations explain how IPC standards are developed and guide you through the whole production chain and show how repair costs can be reduced and quality can be improved with the appropriate IPC standards for each stage in production.

With the introduction of EU’s RoHS directives, the conditions for the whole chain of electronic production from design via CAD and bare boards to circuit board assembly have changed in many respects. The seminar presents suggestions in the form of IPC standards and training which can improve reliability of lead-free circuit board assemblies and shows what the economic consequences can be when quality and yield decreases.

The seminar gives interesting and useful information for everyone working within electronic production such as bare board and circuit board manufacturers, electronic designers, production managers and technicians, purchasers, quality engineers, etc.

The number of places is limited so please register as soon as possible.



40€ per participant (free for members of Estonian Electronics Industries Association), including documentation and lunch.
