Model Based Estimation Methods in Analysis of Electronics Manufacturing

Manufacturing technology has become a significant factor for the competetiveness of the electronics industry. Ever hardening quality requirements as well as the need for cheaper and cheaper end-products call for completely new production methods and put renewed process control methods to a key role.

The project research areas include several research challenges common to all electronics manufacturing processes. For example the need for accurate, real-time estimation of several subprocesses or enabling accurate, simultaneous control of several process variables that can not be directly measured.

The MESTA project focuses on:

  • Enhancing corrosion durability of printed cirquit boards
  • Improving output quality of the microvia fill process

One aim of the MESTA project is to determine factors in the PCB production process that affect corrosion durability of printed cirquit boards and then, based on these findings, develop a real-time monitoring and control system for the production process.

Another goal is to develop a complete process model of the microvia fill electrolysis process in order to further create a control mechanism for the process. The final aim is to cut production loss, improve PCB quality and enable production of ever smaller cirquit boards.

Aspocomp in Finland is our key partner in the electronics manufacturing industry. Tekes, the National Technology Agency of Finland is our main financer.

MESTA is a part of TILLIKKA.
