Wave seven and eight: use the same with soldering lead-free solder in melting point,

like Sn/Ag2.5/Cu.8/Sb.5

Sn/Bi3.0/Ag3.0

6. Attentions:

1. According to the chips size and welding technological requirements, select the

proper wave.

2. Heating temperature regions distribution of upper three areas, and the lower layer 2

areas, corresponding heating waves of the first section/third section/section 4 of the

first/second section/each.

3. There are lot kinds of solder paste, every company chooses is also not identical. For

these reasons, we design this product can set eight waves, each wave has five sections,

each section of the heating time and temperature all can alter. You can reset the heating

waves according to the solder required heating temperature and time.

Foundation for wave set

1. The reflow soldering theory and the temperature wave

When the PCB board goes into heat up area (dry area), the solvent and gas in the

solder paste will evaporate. At the same time, the flux can wet the pad and the

component tip and foot. The solder paste melts, caves in and covers the pad, leading

to the pad and component pins insulate the oxygen. PCB board goes into heat

preservation area. PCB board and components get full preheating. In case of

damaging the PCB and components when it goes into the welding area and the

temperature heats up quickly. When PCB board goes into the welding area, the
