But the\u00a0<strong>initial cost is high,<\/strong>\u00a0and it is\u00a0<strong>difficult to repair.<\/strong><\/li>\n<li>The\u00a0<strong>process\u00a0<\/strong>for SMT production setup\u00a0<strong>is faster<\/strong>\u00a0when compared to THT. This is because components are mounted using solder paste instead of drilled holes. It saves time and labor-intensive work.\u00a0<\/li>\n<li><strong>SMT supports microelectronics\u00a0<\/strong>by allowing more components to be placed closer together on the board. This<strong>\u00a0leads to designs that are more lightweight and compact.<\/strong><\/li>\n<li><strong>Simplicity<\/strong>:\u00a0<strong>In THT, lead wires pass through the holes<\/strong>\u00a0to connect components.
