I am not very concerned about production time, but it is always a thought! Quality is more importnant of course. We have 2 different pastes, with almost identical requirements. We can get close to their profiles, but i am worried that i am spending

If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

Thanks A lot for your help. I dont know what could hold a 5mb song and how to make it auto play when it opens up. Im afraid those sites wont show me a template for something like that? Is there anyone skilled enough that could just go on paint and de

You could also try the ipclistserv "tech net". It is an email list and there are a lot of design engineers that maybe willing to lend you a hand. It kind of reeks to up but maybe worth the time. http://listserv.ipc.org/scripts/wa.exe?A1=ind0807

I am having some problems with some of my pcbs at ive solder. We are using an ersa versaflow. It has an automated spot/spray fluxer (Interflux Pacific 2009M) , 1 preheat stage, a leaded pot/nozzel, and finally a lead-free pot/nozzel. Nozzels move, b

Patrick, you are right. I am sorry. It is a Water based flux. (We have another no clean flux indium 3592 that is used in our leaded process. It is alcohol based and had their base confused) Chunks, yes, this has always been a problem. If ther

After analyzing the pictures I don't think the solder balls are caused by the solder mask. If the problem would be solder mask related the solder balls would only show up on the solder mask but there are also solder balls on the plastic tabs. To me i

GR@ICS, can you be more specific about your up in the Ersa machine please? Nozzle size, pump rate (%), and is your machine equipped with monitors on the solder pots? We have the same machine it sounds like, however we run Pb-Free in both pots. I
