Nitro, I msuggest you get your oven manual out and start reading!! it depends on yoru machine, the point of injection, how many zzones it's designed to cover (some only inject for reflow) what your inward flow rate is, what yoru exhaust rate is and

We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

well to add to your information .you are correct that you will get a cp8 instead of a cp7 and its cheaper.the cp7 range has been replaced by the cp8 because of the y 2 axis control that allows beter pickup of 402 and 0201 components.my moneys on the

You better get to know who the third party service companies are because Fuji just does not care about service they rely on their reputation. If you wanted good service you should have gone with Universal. When you compare machines now days all of th

I called Contact for support the other day. I was put on hold for who knows how long. Found out that the guy (Jim Roberts) I normally deal with has become the latest to leave thier service dept. I can not believe they can support equipment with only

Hey there, trying to get soem useful data on joints that suffer from gold embrittlement. Anyone got any data on effects ont he electrical conductivity of the joints over time? does it degrade quicker than a normal good joint? (let's all ignore the fa

To maybe simplify, contact David Sbiroli(Apps. Engineer) @ Indium corporation. I have worked with Dave on this issue before. He can most likely get you the info you need. 1-800-4 INDIUM PS: Dave F. : My plasma arc accumulator has unusual carbon sco

There are studies out there that looked at gold embrittlement. The overall consensus is to not exceed 5% by weight. As far as the conductivity question, as themo/mechanical creep fatigue sets in, your conductivity will be affected as the joint is s

Make sure the board is stopping at the center of the worknest or you will waste lots of time (you'll get software limit errors when you try to find fids.). If it's not in the center, you need to go in and reteach from scratch (doesn't take too long).

I personally would not get involved with any technology as old as the Q4C. I worked in a factory that had about 20 of those and was not impressed. It seemed like there was always some problem (electro/mechanical) and their service was not "world cl
