    Looking for ESD safe alternative to FR4/G10

    We make various trays that pass multiple times thru our reflow ovens (240°C max). In the past we have been using FR4 but would like to switch to something that is ESD safe. I have found a material called Glastic CBC but it does not come in 1/16” sheets. Can you folks recommend other...

    Aluminum 6061-T6 per AMS-QQ-A-250/11 (plate) versus 6061-T6 per ASTM-B221 (extrusion)?

    What's the difference? I am a machine shop supervisor with a staff of two, that's all, not a rocket scientist nor a metallurgist... please don't judge as I didn't ask for this position! We made a long thin part out of extruded aluminum rather than the plate stock that was defined on the print...

    Underplate for gold - Woods Nickel Strike or Electrolytic Nickel

    We have two very small parts made of .004” Beryllium Copper. They are both chem-etched at a vendor, and then eventually formed onsite. One part is so delicate that it must be plated prior to forming, the other part is plated after forming… not sure why. They are both plated with 50 microinches...

    Alternative to Cu Ni

    Think of a square bottle cap that has 4 .02" fingers on the bottom edges of it that get inserted thru holes in a circuit board, and then get soldered on the opposite side. I don't know the end application, but I could find out if you really need it. I need to keep costs to a minimum. Thanks for...

    Alternative to Cu Ni

    We have a small metal part that we're fabricating out of cupro nickel. We chose cupro nickel because it is solderable and we hoped it would eliminate the need for secondary plating operation. Trouble is, after awhile it yellows. Is there an alternative that is solderable and easy to fab or...

    Unlinked dimension question

    Following the cube example, the hardware we use to get to the 2" plus/minus a fourth, comes from an existing catalog of available sizes so obviously I must model them exactly as they are, tolerances included, to do internal design. The resulting part may or may not be anywhere near the Customers...

    Unlinked dimension question

    Not to draw this out too long but here’s why we do it. Our Customer demands that the cube be 3” max. The part we produce ends up being 2” plus/minus a fourth. Our outgoing inspection department needs a print that reads 3” max so they can ensure the cube meets spec before it goes out the door...

    Unlinked dimension question

    Say I model a 2” cube and then create a drawing for it. When I slap a dimension on one of the sides, the dimension is going to read 2”. But I want to over-ride the text with something else for whatever reason, and I’m prompted with the warning about the tolerance no longer being live. The...

    Snap-fit drawn steel enclosure?

    Sorry, after rereading my question, it does sound vague. Check out the drawn enclosures in the photo at this site: http://www.zerocases.com/metal-products/deep-drawn-components.jsp We use similar square enclosures and we currently 'slipfit' a shallow drawn cover over the open end of them and...

    Snap-fit drawn steel enclosure?

    I know this is not the right forum for this but I didn't know where else to go. Delete if inappropriate. We do a lot of work with small (2"x2") deep-drawn steel enclosures. We're looking for a supplier who provides some kind of snap fit sealing method for same. I can find tons of deep-draw...

    OK To change SolidWorks Re-Seller?

    Hello, We are considering changing to a SolidWorks re-seller that is closer to home. 20 minutes versus 90. The 'new' reseller has stated that we should just let our support lapse and then he would re-establish support thru him without the extra service charge. Pros, cons, thoughts? Thanks, Chris

    6061-T6 Aluminum

    Can someone tell me what the 'T6' stands for in 6061-T6 aluminum? And is there a chart around somewhere defining the available 6061 suffixes? Thanks, Chris

    Looking for lead-free plating for aluminum.

    I am relaying this response from our process engineer, unfortunately very quickly as he was headed out the door on vacation… Although we have had aluminum anodized before, we have no experience soldering to it. We are concerned as to what the solder will wet to. We assume that the anodized...

    Looking for lead-free plating for aluminum.

    Hi, Just popped in from the SolidWorks forum. I'm not a metalurgist, or a plating expert, but the group I work with have been asked to 'look everywhere' for this so I thought I'd give you all a crack at it. We're looking for a lead-free plating option for 6061 aluminum that will leave the part...

    SolidWorks and electronics packaging

    As far as electrical component models, we use CircuitWorks to take a Mentor Graphics board layout data and drive it into SW. Pretty slick. You get the PCB, holes, and parts, but no traces. Downside is that the TOP of the pcb gets driven to the FRONT plane in SW. Part models are only as accurate...
