I have a hermetic package with 1 atm of Helium (5% vol.) and Argon (95%) inside. We have detected the helium leaks at 5*e-8 ccatm/sec. My question is what is the leaking rate of argon. Can anybody provide any insight or information to calculate the r

Capacitor working voltage One very important rating of capacitors is "working voltage". This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. This working voltage is expressed in terms of DC but th

Dave: In terms of heat transfer, air is 78% nitrogen, and the remainder is mostly (20.9%) oxygen (roughly the same molecular weight as nitrogen), with a bit of argon (0.9%), CO2, hydrogen, monosodium glutamate etc. So you would expect virtually no d

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

Sean, If the machines use more than the spec'd 8CFM, are not leaking and work fine otherwise, I wouldn't disqualify them on that basis alone. You may be exceeding the duty cycle rating of your compressor and not necessarily the volume. If Samsung

If you think the problem is occurring in the box and it is wide spread, consider replacing your solder paste with your paste supplier. There are paste formulations aimed at the solder balling issue that some LF pastes create. On tuning your reflow r

I've heard of a series of labels that absorb moisture at different rates and/or change appearance when a specific saturation level is reached. If such labels exist and if they could be correlated to the exposure limits of specific moisture sensitivit
