Testing and failure analysis of electronic hardware
Swerea IVF, Electronics Packaging and Reliability, have worked for many years on practical and theoretical research within the area of electronic hardware. Our expertise includes materials and failure analysis, reliability testing, selection of electronics packaging and process validation. This expertise, combined with an advanced laboratory, are placed at your disposal.
The extremely fast development within the areas of both materials and technology, means that there is an ever increasing risk of more and more faults and mistakes being made in electronics manufacture. These can be extremely expensive if not picked up in time. It is therefore very important to catch, identify, analyse and rectify any weaknesses in a product or manufacturing as early as possible.
We offer test and quality checks, so that you can test and develop your product and processes during the development phase in order to reduce any development loops and thereby achieve a shorter time to market.
For returns, we can go through the materials and failure analysis. Our knowledge of processes, materials and electronics packaging will not just find faults, but also help to remedy potential faults.
We are an internationally acclaimed authority in these areas after having built up different programmes and test processes over the years. Our researchers and our laboratory staff are at your disposal so that you can quickly identify and correct any deficiencies in products or manufacturing.
Cleanliness testing of Printed Circuit Boards
The test procedure is based on IPC-TM 650, Test Method 2.3.28,”Ionic Analysis of Circuit Boards, Ion Chromatography Method”.
The contaminants on each PCB assembly are extracted by placing the object in 0.3 ml/cm2 of highly purified water in a plastic bag of polyethylene, which is then hot pressed sealed. Contaminates on the printed circuit board are extracted by placing the bag in an ultrasonic bath at 60°C for 30 minutes. Highly purified MilliQ water is used and has a specific resistivity >18 Mohm·cm. A small volume of the extract solution is taken directly from the bag with a syringe and injected into the Dionex 300 ion chromatograph with AS 9 anion colon and ion suppressor.
The analysis comprises inorganic ions such as F-, Cl-, Br-, PO43-, SO42- and NO3-, and flux residues from dicarboxylic acids such as, adipic, succinic, glutaric acid and formate.
The results from the ion chromatography analysis are presented in a table with the concentration of the various contaminants in the extracted water in mg/l and the normalised surface cleanliness expressed as µg/cm2.
