Stephano: Since you have not thought through this, it indicates that your discrepancy reporting and resolution process probably requires critical review. Consider highlighting this issue to your quality assurance staff.

We follow IPC-2221 recommendations for Au and don't have a problem as long as the Ni is under 150 microinches.This ensures a consistent process for us.Also we do plasma clean after SMt and prior to wirebond.That makes a big difference. Rob

Hi! Try Philips / Assembleon http://www.assembleon.com and DEK http://www.dek.com. I have experience with them and like their service very much! They are very attentive and professional, even if you are located in CIS countries.

What is the expected volume to be outsourced to the US and where are your distribution sources? Do you have a particular US region in mind? I'm in Northern California - if you are interested in producing here, we can talk further offline.

This sounds like it could possibly be a case of Black Pad. We have had a few issuses with this in the past as well. Who the PWB vendor? I also recommend searching the archives and doing some solder samples with nonpopulated boards

Yannick, I have been involved in a stencil consortium that looked at stencil design, technology, and paste as variables. This material will be presented at APEX 2002 in San Diego next week. This work was done by Rochester Institute of Technology i

Does anyone have a good idea of a simple (GCSE standard) electronics project for a product that can solve a problem, e.g. Temperature controlled fan to cool down a PC. Please post your ideas. thanx

Hi, Has anyone done some research (measurement/simulation) on the effect of PWB vias on solder ball temperature of the component? Would this have some effect on solder joint reliability especially during power cycling? Any comments will be appreciat

Does anyone out there have experience dispensing solder paste with a Universal GDM (4716AL) with positive displacement pumps? I'd like to hear any comments on the success or failure of the machine to dispense consistently, effect of temperature varia
