Referring to IPC/JEDEC J-STD-033B.1 section 3.3.2.2 'The amount of desiccant used, per moisture barrier bag, shall be based on the bag surface area and WVTR in order to limit the interior relative humidity in the MBB to less than 10% at 25°C.' So wha

We just powered up a used GSM1 for the first time and it seems to boot and initalize ok. It is running UPS 3.2.2c. The first thing we noticed upon initial power up is that there is a lot of 'noise' on the monitors. Is this normal due to being designe

Hi Deni- Thanks for the reply. I'll try to figure out what vision system is on it. I know it has two 5.3mil cameras front and back, UPS 3.2.2c os/2. Where do I determine the type of vision system; in the computer or harware spec plate?

I'm not sure- I'll check that. The machine is running ups version 3.2.2c. Previously I just went into the order list and selected to move the component in the list, put it at the end before the repair step and added an end block step after the compon

Really? Where does it say that? I have had the opposite experience and 3.2.2 from the IPC-7525 states for square or rectangular apertures - "Having a radiused corner for all apertures can promote stencil cleaning". It actually recommends circular ape

It's unrealistic to think that two materials with the following disperant properties would have the same reflow profile. From http://www.norplex.com/Carrier.htm Physical Properties / NEMA FR-4 / NEMA CEM-1 Glass transition temperature �C / 130 / 10

Good day, J-STD-033A: 4.1.2.2 Moisture Sensitivity Levels 5-5a For moisture sensitivity Levels 5 and 5a with floor life exposure not greater than 8 hours, a minimum desiccating period of 10X the exposure time is required to dry the SMD packages en

gersla: You're correct that carriers of low temperature material will disfigure and become useless at 125*C bake temperatures. The reason you can not find 70*C bake data is: J-STD033B, "4.2.2 Low Temperature Carriers. SMD packages shipped in low tem
