Hi All, I Need to know What is the main Concepts and Basics to Use IR in Soldering BGA & mBGA Ics, for Example - what are Range of Heating Temperatures - What is the Preheating means !? - What is the best Heat/Time Curve Ive to care about while using

I am evaluating PACE IR300 rework system for micro BGA having size .85mm x 1.35mm. Is anyone out there has any experience of reworking this package size BGAs. Your comments will be appreciated.

No, absolutely not. The BGA balls should collaps by theirselves. No external pressure should ever be applied.

This sounds like sales-type teaser posting, but let's see what we get. When comparing convection to IR BGA rework stations, IR stations perform poorly when: * Evaluation board has no power and ground planes. Worst case PWB as IR energy from bottom h

We are currently looking at purchasing some BGA rework equipment. Could someone give us the pro's and cons of IR heating (top/bottom)vs. hot air convection ? All other tips are also welcome. Thanks

Did you get the solder to the temperature? Determine the temperature of the solder with a thermocouple.

Dear ALL, I Wish to know 1.which type of rework station is best compare to the IR or HOT air convection. 2.Which process plays best reliabilty on soldering after post soldering process. Pls, suggest ur best

Hi aram, Hot air is best. IR takes longer and is affected by the color of the part. Best post solder process that affects solder the most is handling.

If you can use a IR desoldering station, you could try covering the second BGA with aluminum tape. The tape shouldnt touch the second BGA, it should form a 'roof'over it that reflects the IR waves.

I have used a PDR I.R. machine for BGA repair and I personally liked it. The two big features I liked were no special tooling and it has a IR temp probe that is closed loop and will keep the temp where you programmed it. The vision allignment works w
