Wister, I agree with the other comments as far as challenging the customer, and minding proper height/width or better yet area aspect ratios. Let's assume you need to go with a .012" stencil for arguments sake. Talk to your stencil supplier about h

Are these blades coated with something like PTFE (teflon)? If so does the coating flake off over time. Incidently I just got a pice quote and they are 4.5X that of our standard MPM nickel plated spring steel, so I wanted to make sure they would last

Hi, We have a new product coming soon that has a fair number of PTH sockets and headers. I was thinking that it would be good to use intrusive reflow on some of them to even up cycle times between SMT and hand insertion, however, when i called t

Hi Zac, was that board finished with tin/lead HASL or leadfree/HASL? Also what type of flux were you using? Just because a board is fresh out of sealed packaging doesn't necessarily mean that it's going to solder well. The picture that I've attached

I have recently come across a device which has a palladium over nickel finish which when soldered shows evidence of poor wetting to the lead ( i.e. a wetting angle greater than 90�) about three quarters of the way up the side of lead. This is only vi

Below is the long explanation. This defect is most commonly found with BGA components, but can arrise with all components. I see it happening more now with lead free boards that are being assembled with a no clean flux. Best short term remedy is t

Flash gold is just thin gold plating over electroless nickel or electrolytic nickel. Flash gold is electrolytic gold where the panel is connected to a plating rectifier and current causes the plating process to occur. Gold thickness is controlled b

Does anyone have any experience with fired-silver/platinum/palladium lead terminations soldering. I have had issues on nickel over gold plated boards but not with HASL'd boards with tin/lead pads. Is this the norm?

We've never heard of it either. Stained glass widow people use varous types of copper and brass tape / foil in their work. A widely used suppler of this tape is Venture [ http://www.venturetape.com ]. They may be able to help. We're not sure how
