BGA rework station temperature setting method

BGA rework station temperature setting method


1, lead-free preheating zone temperature heating rate is generally controlled at 1.2 ~ 5 ℃ / s (seconds),

preheating zone temperature is generally not more than 160 ℃, the soaking zone temperature control in

the 160 ~ 190 ℃, the peak temperature reflow zone general control in 235 ~ 245 ℃, and the temperature

holding time of 10 to 45 seconds, from heating to peak temperature should be maintained at one and a

half to two minutes.

2, there is lead solder melting point is 183 degrees, and 217 degrees is lead-free. That is when the

temperature reaches 183 degrees when the paste begins to melt lead, tin beads actual chemical properties

due to be higher than the melting point paste.

3, the machine of common sense:
(1), the widely used: the upper hot air + lower dark outside, (2), three-zone models: the upper hot air

+ lower hot air + lower dark outside, (3), all the infrared type: the upper outer dark infrared + lower ,

IMPORTANT: different types of products which heating, there are different procedures when using the

set temperature.
