Folks, Does anyone have data to support that a minimum clearance left around the perimeter of a BGA on a board design can improve its solderability? In other words, if X distance is left open (free of components) around the BGA, could ball solderab

Greg, The increased space and hence potentially increased airflow will have no effect on "solderability." It may effect the temperature that the balls see and that is a different issue that can be worked from a profile standpoint if you are not hit

Steve, I was aware of the rework requirement but was looking more towards the reflow profile. I wanted to know if there was any significant benefit other than rework itself. I suspected there isn't but I just wanted to be sure. Bye the way--did y

Greg, Yes, I did my tour of duty. Is your boss back from Bermuda yet? If so, tell her to check her email! Thanks. BTW, there could be a benefit to moving parts, but that would be dictated by your ability/inability to achieve a proper reflow prof

There is too little heat to make the solder flow properly. Test this theory by profiling on the pad where the solder doesn�t flow well. As the time after posting this thread increases, we generally propose additional theories. Rather than us specu

We have done some work to reduce the amount of time that it takes to post to the Forum. We will continue to work on reducing the time it takes to post a message. This will be an ongoing project over the course of the next week. Please bear with us

Why not use the same calibration tracking, recording, and problem resolution system that you use for other calibratable production equipment, like meters, scopes, and programable controllers? If you have a reasonable quality system, then the tools y

Wave rider is an oven profiler made by ECD. http://www.ecd.com. They are commonly known for their MOLE. The wave rider is different from the MOLE because it is used to measure the temperature, conveyor speed, etc. of the OVEN instead of the pcb.

Hello Mike, There is a software availible that can control the machines you have and are looking to buy, It can also perform line balancing, it has also has many other features. check out their website for more information. http://www.timmsweb.com
