Mechanical Tests and Strain Measurements On Printed Circuit Boards (PCB)
Printed circuit boards are often exposed to high mechanical and thermal loading. This also increases the danger of damage to the printed circuit board, and with it high repair costs or expensive product failures.
Broader trends, such as the progressive miniaturization of technology and changes in manufacturing processes, are setting increasingly challenging requirements for the design and production of printed circuit boards.
HBM has been supporting manufacturers of printed circuit boards for many years by performing mechanical tests on printed circuit board using strain gauges.
You benefit from seamless documentation, reliable measurement data and greater reliability in mobile applications for printed circuit boards.
Current international guidelines (such as IPC-JEDEC 9704), industrial standards (for example the automotive standard with temperature range from -40 to +140°), customer requirements and internal quality objectives require seamless documentation of target values covering the entire production process for printed circuit boards.
When problems occur in the manufacturing of printed circuit boards, mechanical tests with strain gauges can help with troubleshooting. Some examples:
Additional sources of errors occur during end-of-line and ICT tests of printed circuit boards. You can trace these systematically with the aid of strain gauges. For example:
With the increasing miniaturization of components (SMD capacitors, etc.) comes the risk of printed circuit board failure due to mechanical loading. The constraint for ever more compact designs leads ultimately to fitting components even in areas subject to heavy mechanical loading. Mechanical tests of printed circuit boards with strain gauges are also well suited for dealing with these problems.
