. Make a point of cleaning the surface properly for proper wetting, and use the right iron temperature so you can avoid bad solder joints and other issues with your work. Q

. With this, the long-existing handicap with two-dimensional testing is solved. The System targets small products and prevents them from having bad connections as a result of small solder joints, lack of solder, component vibrations and heat expansions

causing solder protrusion. 2. When the solder goes into the vias, it robs the thermal pad from having the optimal solder joint. Less solder = bad connection. 3. The thinner PCB thickness of 1 mm can be problematic because it's easier for the solder to flow out the bottom side and could cause shorting
