You can get reliable solderpaste dots down to 20-30mil dia. with Type 3. Accurate and repeatable dispensing machine for X-Y-Z placement of the dot is critical. Here are the leading machines: http://www.speedlinetech.com/camalot/index.aspx http://

Thanx Dave/Hussman.. We normally store our solder paste in the refrigerator at 0-10 Deg C as per what the supplier recommanded. Our floor temperature is controlled at 22 +/- 5 Deg C and Humidity is at 55 +/- 5%. Recently we have customer asking fo

The paste dispensers work well as long as the humidity in your shop is properly controlled. If it gets too humid, and the paste gets "soupy", then it will take less air pressure to dispense it onto the stencil. Paste dispensers use a controlled, pre-
