Hi, Has anyone done this? X-ray a populated PCB and found voids on chips and some IC solder joints? Is this kind of screening acceptable? I got a PCB with this problem and not ruling out paste, profile and contamination issues. Please Help as it see

Dreamsniper, We would need much more details about your process to help you to determine the source of voids. Type of paste, how long you leave your paste on stencil, your relative humidity, reflow profile, type of oven, oven environment (N2?) and so

I run a D.O.E. and print different water soluble pastes on the same board by mini-stencil and reflow on same profile. WS709 is one of them but Indium6.2 shown less and no void then WS709. P.S.: profile may affect the result. Do U have Via in pad?

What is anyone using to clean Siemens ceramic nozzles. Siemens recommends a 20% ethanoic solution or a 20% acidic solution but they can't tell me anyone who manufactures this type of cleaning solution. I was using alcohol but was told not to because

I'm pretty sure someone at Siemens can tell me, I just haven't found the right person yet. I've been asking field tech's but those guys never have to clean nozzles so they don't know. I'll forward my question to their main office. I just thought some

Wood or Black Light is the common way to call that UV ligth used ie. inside "disco" and used for many applications like to activate the fluorescent particels contained by conformal coating material,adhesives, paper money, etc. Any way ask for TL-08
