the substrate, but its disadvantage is the significant cost increase,cost increases with the amount of nitrogen, when you need furnace 1000ppm oxygen content of 50 ppm oxygen content, the demand for nitrogen is a world of difference. Paste manufacturers

. Benefits for Food Packaging: May prolong shelf life by reducing the oxygen transmission rate (OTR) and total oxygen ingress over an extended period By utilizing EDI LMT, barrier properties may be better maintained when packages are flexed since thinner EVOH layers tend to develop fewer pin holes Features

furnace 1000ppm oxygen content of 50 ppm oxygen content, the demand for nitrogen is a world of difference. Paste manufacturers are committed to the development that can be carried out in the higher oxygen content of the atmosphere a good solder no-clean solder paste, so that you can reduce the consumption of nitrogen

. Assume, for a given condition within the oven, that the temperature of the exit gas and, therefore its density are constant. In order to raise the gas velocity to a level sufficient to prevent oxygen flow upstream one can either decrease open area A or increase mass flow M

. Oxygen content test of nitrogen reflow oven: Usually the oxygen content is less than 0.01%, the welding effect will be perfect. 2. Noise test: There will be a lot of noise in normal reflow oven, but Lyra can reach below 70 dB

. The goal is to reduce operating costs while maintaining a stable oxygen PPM level within the oven to achieve the process benefits of nitrogen reflow
