Slappy, Most of our discussions about flex came before the last great SMTnet.com server transition that destroyed the archives. Consider custom building carriers with tooling holes, vacuum line holes, alignment pins, multiple layers, etc. from uncl

To answer the first post after my initial response we haven't published any of our lead free data since it is proprietary, sorry. As for the nitrogen cabinet it has been proven that over time the Gold plating can build up a layer of oxides that can

I am working on a new product that has a flex circuit attached to an 8 layer motherboard. There are 25+/- connections. I am investigating hot bar soldering vs ACF (conductive film) to make the attachment. I am looking for literature/papers/experim

We don't know dip a about rigid flex. Flexdude wrote "Hot-Bar Soldering, Attaching Flex Circuits Directly To Rigid Boards" [http://www.flexdude.com/Back%20Issues/FCN11-00A.PDF ]. It may help you get started while waiting for others reply. We have n

I am interested in performing SMT Assembly on flex boards that would be a couple of inches wide but 2 to 5 feet long. Obviously quite a challenge. I would like to hear from anyone that may have seen anything similar done, or at least has an idea of h

Hi Chris, I had worked for a flex circuit house for 10 years. You should be able to follow your solder paste guidelines for times and temps. You may want to consider pre-baking the flex if it is made with Kapton. Kapton is Hygroscopic and will delam

Hi CP, I used to work for a flex circuit manufacturer. I am at a CM now and am we have started building RoHS production status assemblies. I personally think flex circuits will have a difficult time with the required temps for RoHS. I spoke to someo

Good Morning Here are a few thoughts. When mfg large flex circuits you will need to fixture them to create a stable production environment. As such, the foot print fo the product grows. So you may require systems that can handle 20 inch width by 38 i

I have a customer that is wanting to use a low-temp solder paste such as SnBi for a lead free circuit, however they are specifying PET for the flex circuit. I have always used polyimide for SMT reflow due to the temperature limitations of polyester.
