Two, technological requirement is high, welding quality is low: when welding, fusion welding directly touches component pins latter end, must upwards climb by component pins top.Therefore, component pins requires as far as possible enough short, and it is enough good that the wetability of scolder and the activity of scaling powder require.When welding, each solder joint has will be through wetting, preheating and welding three phases, so the being heated evenly property of each solder joint and speed of welding will be subject to stern challenge slowly.
Three, cannot weld intensive component pins: for the intensive components and parts of component pins, be easy to occur connecting phenomenons such as welding, draw point, upper tin height cannot meet the requirement of reliability too.
Based on above various reasons, the through hole Welding Problems of mixing the pcb board plate of dress connection also cannot find effective solution so far, becomes electronics and manufactures one impassable bottleneck of industry, from having caused the very big concern of vast electronics manufacturing industry.
