Has there been a definite date for the total move over to lead free? Will it be 2004 or 2008. Also is there a direct replacement for leaded solder, I have read various articles on numerous alloys suggested for the switch, such as bismuth, tin, copper

Comments are: * General purpose RTV (RTV-108) releases an acetic acid (vinegar) during cure and corrodes copper, brass and sensitive metals. It is therefore NOT for use in delicate electrical or electronic applications. However, there is an electrica

Is there anything stopping you from replacing the flat belt solution to a continuous running steel roller chain conveyor? - From there (depending upon board temperature) you should be able to buffer your boards in a vertical buffer station if neede

Hello phil, The use of AOI systems give us the opportunity to auto-collect defect information much the way you're using them now. AOI systems become extremely effective when the collected data is used to perform some positive change into the process.

Hello Phil, We did use an Oracle relational database with an Access front end to input and query data from the system for reports. We did not perform SPC with the Oracle dB. As the whole data collection process was completely customized, we hadn't im

Ideal situation is get a technical rep from the solder paste supplier. They know their paste better, and should be able to work out a profile based on their paste and your oven. Again, a technical rep, not the sales guy.

I'm looking for some data to support my argument that HASL boards are not the most ideal boards for manufacturing involving BGA's and 0402's. I'm sure one of you SMT Gurus out there can point me in the right direction! Thank you in advance!

Hi, I would recommend something from 21 Century at least. Considering it's mostly small batches there's no reason to raise the budget to purchase the Newest series. I think the principle here is something that'll do and do a nice job. If you are a Ya

We have a problem with QFN IC's with NiPdAu plated pads. Our ULC's don't see the pads due to the almost ideal reflection. Vision sees the pads almost black. As we don't have OAL-cameras (which can help in this case, I assume), I am thinking of back-l

We understand the problem of trying to coat over RTV. We have seen the same problem with acrylic and urethane coatings not wanting to stick to RTV. Some acrylics seem to be worse than urethane. Since this is a new product, may be you could pot your
