comparison between BGA rework stations


this editorial , they will compare between various BGA rework station.In the BGA rework area, hot air heating & infrared heating are the most normal repairing method, so, what is the differences between them? They will read in this editorial the major differences . must be aware of the application for which they needs bga rework stations.
Infrared Stations have become very popular in the reworking field. Plenty of tiny rework stations are designed with infrared heating, owing to the advantage that infrared heating has no air flow. They do not require to be afraid of blowing away tiny ICs on the board when they
are reworking. On the other hand, infrared heating can do even heating, which makes the stuff warm with average heat.
The the shortcoming is that the temperature of infrared rework stations ups slowly in the beginning , & when the temperature is up to a specify point, it will be hard to control, on the other hand, after you finish rework, you require to wait for some time for the temperature icy down.
For the hot air gunheating, the temperature of hot air can alter basically, but it is hart to adjust , thus, users ought to select a top quality hot air Rework Stations with lovely controller & can do excellent air flow.
About the hot air process:
But then it's a flip side also , the chips or IC may be popcorn because of not technical control of the temperature, or the ICs can be blown away by the strong air flow, so , hot air guns are suited for the ever technical rework masters.
Some hot air guns are with rotating air flow, the flow is average because of the design of the air nozzles. Hot air soldering have an other advantage that hot air have a pressure can make the chips or IC more closely to the PCB.
Now the most hot selling infrared heating rework stations are: RE 7500 & RE8500 distributed by Jovy Systems .According to our experience ,we recommend infrared bga rework stations .The cost ranges from difference demand of user, usually speaking, hot air guns are cheaper but suits for technical workers, infrared rework stations & hot air infrared heating stations are suit for the who star learning how to solder.
BGA rework is a way of learning that never finish, they may failed when they solder but they get experience from them, hope I can also get some tips from you.
