We looked at the 5DX as well, but it was way too cost prohibitive at the time and ended up purchasing the Yestech stand alone x-ray system. At the time Yestech did not have a comparable system to the 5DX, but I understand they do now. With Agilent

Hi, There is one thing missing still, you must put a TC from the bottom side of the BGA by making a hold on the test board at the TC can measure the temperature at exactly the middle of the BGA. You should be able to the dual time and peak temperatu

I don't think there is any environment where lead free is as good as "real" solder. When you say "high vacuum" do you also mean low gravity? i.e. space? If so my understanding is when the tin whiskers short out the vapour does not settle down but in

I was wondering what the difference between "Y" type feeders and "HM" type feeders where? Also I understand that the "FV" type feeders are pneumatic rather than manual advance, what is the purpose for pneumatic advance if manual works just fine? Are

I understand installing BGAs and QFNs with water-soluble fluxes can cause serious near and long-term reliability issues as a result of PCB erosion from trapped flux. Is this a valid concern? There is not a tremendous amount of data online support

my guess is yes or they are just lazy. if you quote a job then you should know up front what you have to do. i am in the business of building 1 to 10,000 boards, and understanding that not every job is fun, but that's the nature of the beast. if you

It's a safe bet that your solder alloys will merge and form a proper solder connection at ~230*C for 15 to 20 seconds. At process conditions with less time and temperature, it's a lot of bla-bla-bla. In order to understand the quality of the solder c
