As is known to all, useSolder pasteAfter the printing machine is tinned, the electronic product board needs to be mounted through a surface mount machine and then reflow soldered. Such a complete production line has strict requirements for the time of each link; otherwise, there will be many poor-quality products after soldering. So, how long does reflow soldering need to be done after solder paste printing? Now, JJY Factory will explain:

We know that after solder paste is printed, the active ingredients will volatilize after being placed in the workshop for a period of time, and the solder paste will become dry and hard, which is not conducive to soldering. Therefore, in order to ensure the success rate of the product's soldering, it is necessary to perform reflow soldering before the solder paste dries and hardens. Based on years of experience, JJY suggests that after solder paste printing30A patch is needed within minutes.2Reflow soldering is required within an hour. Adjustments can be made appropriately based on environmental factors such as temperature and humidity in the workshop.
