Soldering technology


We can assemble your PCBs with electronic components using SMT (Surface Mount Technology), conventional wave soldering, THR process (Through Hole Reflow), manually or a combination of all technologies. These methods can use leaded or lead-free solders. We will ensure the requirements of your circuit boards and systems are met, regardless of the technology used. We will also gladly handle materials procurement for you.
