In the electronics manufacturing industry, PCBA (Printed Circuit Board Assembly) is one of the key processes in the manufacture of all electronic products. And plug-in technology (Through-Hole Technology, THT) as a traditional assembly method, although in the surface mount technology (SMT) after the rise of the gradual replacement, but it is still in many areas to give the cardiovascular status. Especially in applications requiring high current, high power or high mechanical strength, plug-in technology still has irreplaceable advantages.
