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

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

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

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

Hi, We just purchased the above two machines and they're still in the trial period. We have problems with air requirements of the above two machines. For example, Samsung CP45 is listed at 8 CFM only, but it will kick off the compressor (rated at

Just to clarify: I'd say that it will potentially save money by turning the wave off at night, but the savings are minimal. But...If your power rates are cheaper during off peak hours (at night) like some power companies offer, it may save you money

We find that the raw BGA's pad sheared surface has the SnPb solder at various Z heights whereas the assembled BGAs pad leave a smooth layer of SnPb along the pad. Like to understand the cause for the difference. Who could guess? Solder joint streng
