An electronic device so made is called a surface-mount device (SMD). Surface Mount Technology Through Hole Technology • SMT enables to build highly complex electronic circuits into smaller and smaller assemblies with good repeatability due to the higher level of automation. It is also more cost and time efficient. • With on-going trends of designs that save space, miniaturization, increase in contact densities and market trends of connectivity, autonomous driving, surface mount connectors are continuing to be widely adopted across variety of end use markets including data & devices, automotive.
