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

It is a AVX TAR series. Commonly called a bullet cap and is now most likely obsolete. AVX 9915 is a date code or lot number. 15uM is the value, probably 15 micro farad but not sure.

What is the spec or true classification for the leads for an Electrolytic capacitor? Is it a : 1)Flattened coined lead??? or 2)Flat Lug Lead??? There is some confusion as to how we should be inspecting & accepting the toe overhang on these per IP

Once a long time ago I had a board where the cap beside a tantalum shifted in the oven. I phoned our HQ plant and was told that they had the same issue and that it was the tantalum capacitor outgassing. We just applied a dot of glue to the cap. Try b

Hi Mika, I used to work for the largest chip cap manufacturer in the world, and by far the largest problem we would see was cracking due to incorrect z height adjustment on Chipshooters. It can also cause solderballs and bad joints by displacing th

Hi all, At our Fuji CP-6 machines we place a lot of 0402:s, 0603:s and 0805:s chip capacitors. Our problem is that the height of the components can sometime be very extreme from different vendors. I am sure you all have experience of this phenomenon

Anyone have experience wave soldering rigid flex assemblies? I've just picked up a new job from a customer; it's a rebuild for the company, but new to me. The customer had previously taken their business elsewhere due to delamination problems with

KRIKIES! If that wasn't a sales pitch, I don't know whut was, me lad. Optimizer is good for DoE's and process characterization, but no substitute for the artform that is wave soldering. When me lads here in Purchasing get PCB's from all over the w

Your puzzlement about blowholes in PTH solder connections during reflow soldering comes from: * Boards are hydroscopic. So, moisture content of the board is uniform. * Gold plating is uniform. * Nickle plating is uniform. * Copper plating on your PTH

Welcome to RoHS. Or, at least, to the version of RoHS that I've had to deal with since I started with my current company. Blowholes and pinholes seem to be common in PB-free manufacturing. At least, they have for me here. I also note that IPC has
