Quality assurance of printed circuit boards with optical 3D measurement
Optiprint is a supplier of highly innovative printed circuit boards for use in medical engineering, the automotive and sensor industries, and space engineering. When the company was probing the market for a non-contact, areal surface measurement system, Bruker Alicona's 3D measurement systems attracted its attention. Optiprint now relies on InfiniteFocusSL in the quality assurance of printed circuit boards. The solution by Bruker Alicona combines dimensional metrology and surface roughness measurement and allows Optiprint to measure complex, miniaturized component surfaces with just one system.

3D measurement of topography and flatness
Today's printed circuit boards are carriers for simple to highly complex circuits. For 30 years now, Optiprint in Berneck (Eastern Switzerland) has been producing highly innovative solutions for circuit boards. New high-performance materials and more efficient ways of assembly, such as the Chip-on-Board technology, are becoming increasingly relevant. In light of these challenges, Optiprint was in need of a system for areal topography and flatness measurement of so-called milled pockets."Bruker Alicona's 3D measurement system have allowed us to optimize our processes significantly and take major steps in securing the quality leadership of our products," quality manager Simon Hütter explains. The 3D measurment solutions provided by Bruker Alicona have made it possible for customers of Optiprint to ensure flawless chip bonding (attaching of the chips) and wire bonding (attaching wires to connect chip and circuit board carrier).
How Optiprint succeeds with Bruker Alicona solution
3D measurement system for form & finish
- Easy, fast and traceable measurement of form and finish on micro structured surfaces
- Users measure both form and roughness of components with only one system
- With an automation interface, InfiniteFocusSL is also applied for fully automatic measurement in production
