The Christian Koenen GmbH from Ottobrunn has successfully organised their first Technology Day after the Corona-related break and thereby demonstrated, how the high precision required in fine pitch stencil printing can be realised.
When welcoming the participants, Michael Brianda, Managing Director at Christian Koenen, expressed his joy that now such events are again possible with personal contact, and then viewed the market situation. More and more complex circuits combined with a high mix of shapes and sizes as well as often thinner circuit boards require smaller printing and assembly tolerances. The process window is getting smaller. For reliable precision printing the choice of material and tools is given great significance. With step stencils the paste volume can be optimised. Coating the stencil improves the release behaviour and circuit board support during printing ensures for stability.
Circuit board support has great significance
Based on the technology trends Michael Zahn, Global Business Deve¬lopment Manager of Christian Koenen, illustrated how the circuit board support ensures for the error -free stencil printing. With insufficient support, bending and movement of the circuit boards can cause, among other things, solder bridges and beads to form as well as poor paste release. A large area rigid and solid support prevents this. He recommended a design with 3D software, because with that the component contours are followed, which ensures maximum support. Michael Zahn also presented a variety of application examples.
