I'm experiencing an impedance breakdown on an 0805 ceramic cap. In the application, the cap is at a 16V bias at all times. The unit failed in an extremely high humidity condition. We are using a NC flux and have determined there was flux underneat

Very strange...I just logged into the internet to come post this very question for all the lurking experts. We have a 16 layer rigid-flex that we have never baked. Our board vendor is expressing concern that we do not perform a pre-bake before assy

I have been confronted with a MPM with a rheometric pump head on and have not had much to do with these. It is giving varying results on the down line paste AOI and is not responding very much to changes in pressure, speed etc. It is a 16inch pump, w

Hey all, i'm hoping to get some feedback from the community on baking process versus a dry box. current process we have for rework of PCBs is to perform a 16 hour bake cycle on hardware before BGA rework is performed. however this process is ineffi

Hi guys, I'm working on a design involving a 223-pin BGA with 0.5mm pitch (ball size 0.3mm) with a 16-bit DDR3 controller involved. Currently routing a track between two balls is resulting in a track width of 0.1mm and a spacing of 0.077mm. Now the

I have just started an assembly which uses a 16 mil pitch QFP. We ran on Saturday, using a type 3 solder paste. (working Sat's really sucks) We really struggled with paste release after the stencil sat for 15 minutes without printing. Apertures clog

Thank you for the answers to my questions. We are running two-lead LED insertions. Most of our PCBs are square between 9" and 14.25" in a 16 x 16 array, so pitch ranges from 0.52" to 0.90". Further complications are that most of the boards have th

Are there any softwares OR functions inside of the softwares that allow a designer that is creating a very large complicated wiring diagram with say....many terminal blocks and connectors etc... to run a point to point check on his drawing? Bascially

First, why is there appears to be no marking on simple capacitors when there is a code for, yet there is markings on resistors? Attached is a interesting table, it came about after I spent hours and hours and hours looking on Internet from a 16 Volt

Interesting, I could not find anything via a website search some of the links came up as 404, others a "home" page and some never went at all (or took too long) So I turned to google and found http://www.smtinfo.net/docs/tombstoning.pdf a 16 page a
