The Area Ratio Calculator App can be used to quickly calculate from your smart phone the area ratio of a stencil aperture, aspect ratio and solder paste transfer efficiency. Also helps select optimal foil thickness and solder paste.
If you have a stencil order with us,
please use this link to check your order status.
You can calculate the Area ratio for Rectangle, Square and Round shapes.
Aperture size can be entered in mils or millimeters.
Aperture size and foil thickness can be independently vary to determine optimal paste release.
The app also calculates paste volume and aspect ratio (for rectangles only).
The app will also suggest Solder Paste Type based on the aperture size.
