Scott - all sounds good. My primary concern is the residual flux left behind under the BGA. Will moisture entrapment become a concern over time? I believe that may be dependent on the flux formulation. I know that some no clean fluxes actually become

In the early days of SMT we were using vibratory bulk feeders for chip components. It was quite obvious that some of the components had to try several times getting through the gravity trap or with the right side up through the light sensor. As a res

I Like your analysis here. I dunno the whole story, but I've tracked parts popping/falling off to the metalazation of the parts, from various suppliers, as most suppliers have some type of pre-tinned coating on the leads.(not that this means anything

Chrissie, There is no "silly" question. It seems to me that, not with standing the issues highlighted in your posting, notably - risks, time, etc.. Your time would be much better spent determining the reason for the reject. If your placement equip

Bollocks!!!! We are unfamiliar with the term overturn, but it can not be that uncommon. Our intial inclination is to barrel into this SMT Engineer's nap-zone and blast him, but it might not be a politic approach. So, maybe we'll temper the tack we

Hi: How simple or complex do you want? We run PFS software, but for our Feeder Maint we used access and just wrote a simple pgm and tied it into our PFS. What PFS gives us is how often the feeder is change out and this is used to base a feeder PM

Don't forget moisture senitive devices. If you have them on the bottom side, usually you do the other side before it is an issue, but if you are going to store the boards for a while it could be an issue. Where I am, partially building product then

I would like to start a new web site that tracks, monitors etc the policy and hostile blackmail type license fees and support policies of ICT and PCB assebbly equipment companies. I would also like to have a forum where people can log their experienc

Good Idea. I just wanted the people to get the point. Any suggestions? I really want to start this forum. If we can track good and bad experiences it shows trends. See the thing is an OEM has to treat every license sale the same. For instance if they

Hi, Does anyone know of some good software for managing component consumption in manufacturing and keeping track of what products use what components, and the consumption rates over time. This lets us forward plan component orders for future product
