The Nudge Test

Postby Coleman » Wed Jul 31, 2013 1:00 pm

Just finished reflowing a PS3 and figured I would record the nudge test. Some people are a little confused on how to go about it. This is how I do it. I use the TX xclamp removal tool and slide it across the motherboard until I hit the chip so I know the tool is sliding flat along the board. Whence I get to the BGA I just move it maybe 1mm. If it doesn't move easily then it's not fully liquid and do not force it.

Hope this can help someone.

Good job Matt, I sure it will help those starting out.

I remember really wanting as many nudge vids I could find like this in the early days cause nudging wasn't my thing, I managed to find my way in the end after lots of support from the forum though, it's not as daunting as it seems and once you have done it once it automatically becomes part of your reflow process.

Nice! i gotta get me one of those TC flex tubes 8-).

here is some more nudge goodness lol. i took this video back when i first started working on consoles.. you can give them a pretty good nudge without worrying about bridging balls, i recommend using wooden skewers.

Nice vid surbo, thank for sharing.

I use a wooden Choptick from Ching Chang Chinese takeaway to do my nudge tests :D

By using a wood I can slide it along the base of the board without fear of damage to the board, the added stability and friction helps me control the leverage of my nudge.

My hands are too shaky to do it any other way :oops:

For those starting out, and also my preference is to nudge both corners to make sure it is fully soaked!
Nudge testing in my opinion is one of the most important things to learn, so simple, but also so important in telling you have hit the sweet spot. The gentlest of touch is all that is required here. Trying to remember who it was that performed the "barge" test.......Will any chance?? :lol:
