| Does anyone know of a web site (or other source) that illustrates the orientation of polarized SMT packages with respect to the carrier tape sprocket holes? | | THANKS, | | Doug | Doug: I believe EIA-481 is the spec. you're looking for. You ca

| One of our board fab houses is asking (again) to eliminate the reference designators and polarity markings from boards. This isn't feasible for thru-hole, but what is the industry trend on surface mount assemblies? | Who is working for who? I w

Our co. is thinking of moving to smocks, but we aren't there yet. However, I can understand why we might want to. Have you ever seen the static buildup on a wool sweater or a polar fleece vest after rubbing against a chair all day in a cold dry pra

We are implementing an AOL inspection system into our surface mount process. I would like to hear from anyone with an opinion on the different types of AOL and why they feel this is better than another one. Any information will be greatly appreciate

Hi Barb, First of all I think you are looking for AOI system, not AOL. As per my experience AOI checks for present, absence of the component, wrong polarity, wrong component, misaligned component, tomb stone, upside down etc. It also looks for solde

I think I read a thread very similar the other day but can't find it. If I remember correctly, the component database for that part was polarized and pre-orientation was used for camera inspection. It turned out that the optimization module in the

ICT and AXI are two different methods for MDA. ICT checks component values and polarity- component and circuit electrical testing while AXI checks solder joints- volume, voids, bridging, etc.... Typically, AXI is in the SMT process engineering and QA

The way that the last two companies that I have worked for do is, as soon as the I.C is programmed it is marked with a either a gray or Yellow sharpie (just a small dot) in addition we always tried to make sure that this dot was at the end of I.C whe

you can purchase a license from Fuji to be able to directly import CAD data. It's the fastest and most accurate way that I am aware of. Also, it gives you the option to import the board outline as well as layers of the CAD so that you can see the s
