This type of technology offers better advantages, especially with high-density packages where terminal spacing has been reduced. Through-hole insertion is becoming undesirable for this technology with the limited spacing available for drilling holes and inserting leads. SMT assembly and technology has gained popularity as a proven technique for a more reliable assembly with decreased weight, volume, and cost. SMT circuit board assembly requires a high level of automation and technical engineering expertise to assemble parts into a functional unit.
