It takes time for the moisture to penetrate into the body. I think the 5 years of ambient would be more the culprit than washing the boards. Especially since you are baking them after wash. Get a few of the ICs and put them loose on a board and put

Years ago when we ran a solder paste evaluation we used the 2.4.44 method mentioned above. What we did was to print several coupons and let them sit for various times to see how the tack changed over time. Our goal was to see how long after print w

These are inexpensive radiation monitoring devices and it is possible, when they are calibrated to a Cesium-137 standard (at 600 keV), for the meter to read higher than the actual value at lower x-ray photon energies. [Glennbrook Technologies Caution

Hello, Electricity cost is getting high. May I know from you if you have �energy conservation� programs? Right now we implemented the following programs: Purchased an inverter type aircon system (office aircon turn off 30 minutes before going home),

Does anyone have design knowledge of why some manufacturers remove solder resist from the area around pads on fine pitch devices? What purpose does it serve? I only know that it would be better for AOI as you would not have light being reflected fro

I totally agree with Wolfman. I recently had the SMA responsibility for a new product from a new customer. The PCB had 600+ mounting positions. It took me almost two days insering them into the part library because an unusual number of the positions

Humiseal recommends a 1 to 1 mix ratio of 1B31 and Thinner 521. I have for that I need to thin my ratio more to get humiseal to spray correctly in our PVA650. Also I am using Humiseal 1B73 but the tech data sheets say the same for spraying. Try thinn

Those machines use DOS, so unless you can find DOS drivers for your printer, then I think you are stuck using Dot Matrix, which don't need special drivers in DOS. Plus, I believe those machine use a Japanese version of DOS, so US drivers may not wor

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
