Thanks Rob, I have samples and production quantities that we are running on leaded assemblies now. I guess my next question would be, if you are already building lead-free assemblies, how are you processing the electrolity and tantalum caps? The o

I am getting a lot of false calls on our AOI(YTV F1)on low contrast part markings like brown-on-yellow tantalum capacitors and etched oscillators, and on lead banks where the pcb has the part outlined in silkscreen. We are contract and cannot change

Hi Prem, OK... Is it definitely ok before the oven, as it's a big part to move. Never had an issue with them. Has the part got the correct z height on or is the paste being displaced on placement What machine are you placing it with (is it laser

Hi Robl, Thanks for quick reply , I want to see you my attachment first ( forgot to attach in my first share ) .As i said earlier ,Im suspecting termination design made by vishay & I never seen these kind of design from other alternate vendors which

Hi Prem, it will really help if you provide more pictures and metrics. Pad layout, part datasheet, stencil design and most of all picture of the misplaced part on the board. This looks like a very interesting case and I am willing to help you, but t

Numerous technical papers on the web document the moisture sensitivity of tant caps. Here's one: https://nepp.nasa.gov/DocUploads/CE5125B5-E0EB-4CFA-8867BE3F3E342CA5/moisture%20effect%20Ta%202C%20M.pdf

Hi, In general Tantalum D & E case packages prefers 12mm Reel with sufficient height. Make sure that no external force has been applied to the reel ( where it causes pocket deformation) thus leads to prevent smooth component release. Slowdown the noz

When I evaluated a new glue type, I simply used a shear force tester (Chatillon) to compare the cured strengths of the different glues. I sampled parts of different types; 0805, SOT23, 1206, and various tantalum caps. I analyzed the data based on e

It's always safer to use a higher voltage cap than a lower voltage cap. It isn't a fuse... There is only one case where we dropped the voltage on a cap. We were using a tantalum cap that was rated to 16V, but had been built in the standard packagi

Sorry i didnt explain it vey well,the parts that are misaligned are always sitting next to these particular tanatlum capacitors.It affects 0805 parts and A tsop36 and can even cause a short on a bga right in the corner where the tant sits.If you chan
