Degassing - the air in the void above the electrolyte expands, or in some cases the electrolyte vapourises, blowing the top of the cap from the base. Sometimes electrolyte can also leak out around the base seal. This is also a failure as the cap wo

| what is your experience about the presence of the voids in the joints ? | Are they dangerous and when ? Vincenzo, Voids in solder joints can be caused by a number of factors. Let's begin with the flux vehicle in your soldering media. If the prope

Hi @calebcSMT, It is generally recommended to avoid coating the entire body of aluminum electrolytic capacitors. These capacitors rely on the venting of gas in case of failure or overvoltage conditions, and coating the entire component could hinder

The vent is there for reasons as the name implies. It's a safety feature to prevent the cap from exploding if over-tasked. Yes, without the relief on the end, the caps have a potential to become missiles when they go. I had one go off when my hand

We have a RAD5 and RAD 8, both of which have the Expanded Range Verifier. Has anyone had success verifying the correct value of electrolytic caps? Our machine stops several times a day for a false failure, and Universal isn't much help. Thanks John

We've seen issues with Elco's for years on boards with a lot of copper (higher than normal temperatures. We found that the 250C caps failed on the "burn in" tests as they has lost a lot of electrolyte in the reflow process. On some brands you could

What is the inspection procedure How to test leakage current Is 100% checking is required at IGI inspection What is the shelf life of the capacitor How much period shelf life is recommended for these capacitors How to check the ripple current of thes

Obviously, if your customer instructs you to use a certain flux type, using THAT flux type is probably a good idea. Responding to your question: Chloride is one of the more detrimental materials found on printed circuit assemblies. Chlorides can com

I will try outline Theta and Z-axis servo issues, we were facing last time. Story behind. Our 750 is used seldom and last time after switching it on initialization procedure ends with T axis of right head: Servo alarm. Opening front cover of 750 two
