The upper heater: hot air reflow heater,make the chip heated evenly.

 

The bottom heater and infrared heater can heat the back of PCB,prevent the PCB from deformation.

 

All of them can set 8 segments heating ,cooling and constant temperature parameters, store 10 groups of temperature parameters.

 

 

Accurate temperature controlling system

How to get the accurate temperature is the most importent aspect for reparing BGA chip.

 

As we know, how to control the temperature is very important when we soldering or desoldering the bga, our machine use PID control, the data acquisition frequency of our machine is 10ms(which means every 10ms the PID will grab the data to correcting the temperature,), but for most of bga rework station from other company, their PID grab frequency is 30ms,this is a big difference between 10ms and 30ms,

That’s why our machine is more accurate.

 

 

HD color optical alignment system
