ROLE of THE PRODUCT
Visualization of Warpage
in the Reflow Process
Warpage and flatness of the SMT components and the board due to heat in the reflow process cause SMT defects such as open, crack, and head-in-pillow defects. The cause of these SMT defects cannot be found only by simple inspection before and after reflow, which leads to poor yield and outflow of defective products. Therefore, it is necessary to analyze the warpage/flatness for each temperature with respect to the solder thickness. 4DScanner 2 reproduces the temperature environment of the reflow environment and visualizes the warpage and flatness of the SMT components and board during heating, allowing you to know the cause of SMT failure.
SMT defects to solve
It occurs when the terminal and solder are not in contact at the solder freezing point.
Occurrence of stress due to increased warpage and flatness after the solder solidification point.
Warpage and flatness increase before solder solidification point, causing solder oxidation.
Visualize the amount of deformation of the board, IC package, and connector housing due to heat.
Visualization of the floating amount of IC and connector terminals the board surface.
CONCEPT of THE PRODUCT
3D movie analysis
It is an accurate measurement result that reproduces the reflow environment, an element necessary for the Reflow simulator, but it is just information. Testing the hypothesis for SMT failure is the goal behind the measurement.
4D of 4DScanner 2 means 3D and temperature. By making it possible to analyze the heating shape change in the reflow process with a 3D movie, you can make imagination a reality and make intuitive decisions. This narrows down the path to improvement of SMT defects and leads to problem solving with the minimum necessary approach.
VALUE of THE PRODUCT
From micro bumps to substrates
Measure with one unit
Ultra-small BGA bump of 50 μm from 200 mm substrateIn addition, it is possible to measure one SMT component with a large variety of types without complicated setting.
Shiny to matte
Without spraying things
How to cut light with high brightness blue laserAdopted. Allows measurement from silicon wafers to molded packages without pretreatment.
Not only the result
In addition to the flatness of the terminals, the bending of the housing can be analyzed with a realistic 3D video,Analysis of causal relationship between terminal flatness and housing warpageIs possible.
Not just heating
In reflow environment
Instead of heating on one side with a hot plate or halogen heater, use the same hot air as the reflow furnace Convection heating To reproduce the reflow environment.
