Industrial project
Research based on failure analysis and reliability investigations to significantly increase the quality of electronic products

Aim: Projects aimed at the research of surface mount technology processes at electronic production by failure analysis and reliability investigations. The failure mechanisms revealed by the analyses might significantly increase the reliability of new product versions. Results: The knowledge accumulated during the research is mainly concentrated on the solderability of printed wiring boards and components. There are many factors affecting wettability and thus the quality of the solder joint. For example: acceptability of surface finishes, contaminations and several production technology parameters. Research results had been continuously fed back to the industrial partners financing the projects. This led to successful development of product and production processes. Project Leader: Péter Gordon
Researching data clearing algorithmsand development of a data clearing method

Aim: Analysing the customer data provided by the sponsor to estimate general data quality. Furthermore the project proposed an approach to detect data quality failures and a complex method containing algorithms to eliminate them. Results: During the research the provided data have been deeply analysed. IT has been stated that the quality of the stored data is rather varying depending on the date of storing and the type of its source application system. The failures were classified and different solutions were provided for the detection and the elimination for each class. The main focus was set to the detection and elimination of duplicated entries where a half-automated solution was provided as the main result of the researches. Project Leader: Péter Martinek

Build a knowledge base about the most frequent problems of the automotive electronics such as: contamination on the soldering surfaces, bonding pads, etc..; soldering failures; surface finishing problems of the PCBs; unknown material detection and analyses; corrosion problems and electrochemical migration; wire bonding failures. Study the quality and reliability problems of the products prepared by costumer. Support the costumers with electronics and material science expertise. Project Leader: Balázs Illés
Research and development of automatic optical end control hardver and softver system for PIN insertion processes

Investigation the effect of the surface-finishes, fluxes and solder mask on electrochemical migration.

Aim: Study the effect of different soldering materials in different combination on the phenomenon of electrochemical migration. The following soldering materials were investigated: four surface finishes (OSP, iSn, HASL (SnPb) and bare Cu); four fluxes; and PCBs with solder mask (only one solder mask method) and without solder mask. All together 28 different test combinations were examined. Results: Special measurement setup was designed for the experiments. During the measurements it was observed that the iSn and HASL samples contain more water molecules or OH groups (perhaps chemically bound) on the surface than the bare Cu and OSP samples. The water or OH groups can adsorb the water molecules from the gas phase easily on the surface of the sample during the THB test and due the proton conductivity of the water can cause the SIR drop that we encounter. On the other hand, on bar Cu samples a continuous water film should be present for getting SIR drop. The baking process according to the DIN-32513 standard and the reflow profile was not enough. The baking process at 150ºC/16h was enough on the non-fluxed samples but the fluxed samples needed an additional drying. Project Leader: Gábor Harsányi

We have supposed possible development and optimization methods for the costumer. Project Leader: László Gál
Research and development on testing and assembling electronic module circuit prototypes

Aim: Researchingthe key steps of surface mount electronics technology: electrically conductive adhesive technology (newmethods to cure isotropic conductive adhesive in infrared and vapour phase ovens) and investigating the accuracy of automated component placement (equipment characterization).The economic applicability and the effectivenessof production plays extra importance because of their high influence on the quality and reliability of the module circuitsto be produced. Results: Initialtests and experiments were made to define component mounting accuracy ofthe newly arrived TWS Quadra DVC Evo automated assemblingmachine, also in comparison to the existing machine.Statistical analyses were madespecifying placement accuracies in X, Y andΘorientationsfor both machines. During the research on the technology of electrically conductive adhesives -an alternative method to soldering technology -. we have definedcuring parameters with which we realized electrically conductive adheredjoints whose mechanical strength were acceptable in normal functioning conditions.

FEM simulation of elastic deformation of stencil on the typical PCB surface

Aim: The topography of the PCB surface has a high level of variation in the vertical dimension. Since the solder resist on the ground is much lower in comparison with the solder resist on the copper. These protruding areas can keep-off the stencil from the surface of the PCB leading to soldering failures. The aim of the researchis to have a closer look on the local elastic deformation behaviour of the stencil during printing process, and to analyse possible stencil distortions due to squeegee pressure and theireffect on the printing quality. Results: During the research we have carried outinvestigationon the stencil bending during the printing process. A FEM model has been created which can predict the necessary distance from a protruding area on the PCB surface to obtain a full stencil bend-down and to eliminate the so-called “gasketing” failure.The minimum technological distance (TD) between fine pitchpads and the pattern causing the level differences on the bareboard can be added as a design guideline for Printed Wiring BoardsCAD software. Furthermore if the necessary distance cannot bekept due to the high density of the electronic circuits, the extentof the required stencil aperture volume reduction can also be definedbased on our results.

Aim: Researches and analyses on automotive electronics which have production failures or malfunction (observed by the end user). The automotive electronics are supported by the costumer. Find relations between the studied production failures and the quality of the production technology in order to improve the yield of the production and develop new production technologies. Results: During the research we have carried out special failure analyses and reliability investigations on the products of the costumer and examined the production methods applied by the costumer. The obtained resultsand our other experiences (earned during the previous cooperation with the costumer) have conducted us to the root causes and effect mechanism of the studied problems. In this way we have supported the costumer with our knowledge about the electronics manufacturing and the quality insurance, concentrated to the related technical and economical aspects. We have supposed possible development and optimization methods for the costumer. Project Leader: Balázs Illés
