. After the circuit board enters this zone, the temperature rises rapidly and exceeds the melting point by 30-40 degrees, that is, the board surface temperature reaches 215-225 degrees instantaneously

. The small reflow soldering machine must not be too long and the temperature is too high to cause copper and platinum blistering; the solder joints must be smooth and bright, and the circuit board must be tinned

. TPHH-TPHL depends on reflow oven’s capacity (about ±10?). Temperature is kept unchanged for about 40~120S as preheating zone, again rises quickly to reflow zone, finally cools rapidly to cooling zone

The primary use of reflow soldering oven is in the SMT process. In the SMT process, the primary effect of reflow soldering oven is to place the PCB board with components placed in the track of the reflow soldering machine, after heating, heat preservation, welding, cooling, etc

. Typically, the thermal tab and the pad are the same Nominal size. The basic principle is that your goal is to have even paste distribution on all pads after the reflow oven
