Circuit board process description:
Process technology: lead-free process
Double-sided patch on the board: first TOP surface (D1/D2/D3)
Reflow soldering setting: welding maximum temperature is 245-250 °CC, super 230 °C welding time control 40-60S.
1: The temperature of the soldering iron is controlled between 330 °C and 350 °C.
2: The connector cannot be welded, and the left and right are skewed and raised.
3: The tin point should be full and bright, and there should be no sharp edges, less tin, bubble holes and too much tin.
