In contrast, electrical testing is more accurate when looking for a short circuit or open circuit faults. Visual test can be more easily detected problems in the early stages of production process. Thus, visual test can ensure the highest product percent of pass. SMT assembly is an alternative to the through-hole method of PCB manufacturing, which had its heyday in the 1970s and 1980s. As electronics manufacturing continued to gain momentum, a more efficient, better process became necessary. SMT assembly was born out of this need. SMT assembly has a broad range of uses. The SMT process starts at the design phase, where the various components are selected, and PCB designed using one of the software platforms such as PADS. Here all the design features are included, and the PCB layout defined. ... X-ray testing: The testing is done as part of a standard check on lead-less components in PCBs manufacturing, such as.
