Get both datasheets out and compare the pin-out, Repurposing a land pattern from a part that's close, but not exact,ĭouble-check your work. Is there a moral to this story? Probably. Well,Īt least I didn't do so until trying to get my new PCB to power up. Naturally, I assumed that the pin-out matched what I needed and Iĭidn't hunt down an LD1117A datasheet to verify the pin-out. The first time I've used a non-standard regulator, so I really Most do, but the LD1117A (FIGURE 2) does not. Took for granted that all three terminal regulators follow the 78XX

But did I follow my own advice? Well, not this part of it. If I were to follow my own advice, it wouldn't have been a Recently, I was looking in my Eagle library for a low-drop out

On the topic of CAD software land patterns, consider, too, when youĭon't have an exact match and need to adapt something close. Have saved me (and the customer) a lot of time and money. An extra few minutes spent looking at those things would That while originally laying it out, but once I went back to check, it Pad size and through-hole hole size in your design check, especially if It's always a good idea to look at things like footprint, SMT That you'll have to use custom libraries no matter what CAD package Sure, but with so many new components coming out, it's quite likely

Or they may have come with the original install. These may have been user-created libraries, In both cases, the real solution was to modify the parts libraries Oddly, because of drill size variation, I could wiggle The breakaway connectors callįor a 0.045' hole size, while the library package used a hole size In Eagle was 0.032' while the datasheet specifies a 0.040' The drill size used for the Molex connectors in the library package Comparing the hole size for that, lookĬlosely and you can see in my callouts that the holes are the same sizeĪs the holes for IC1 (callout C) and are slightly smaller than the holesįor my breakaway connectors (callouts B and D). Looking at my board (FIGURE 1), 'A' shows the spot for I thought that I had used the correct parts library - and uponĭouble-checking found that I had - but the holes sizes used on the Into Eagle and looked a little closer, something didn't look right. The drilled holes were tooĪt first, I was upset with the board house, but when I went back After getting theīoards fabbed, I started to assemble them and discovered that none of my

It was a PIC micro boardĭesigned to run a couple of motor driver boards. Some time ago with a board I laid out in Eagle. We hate to do it, it was all on their dime and we still had to chargeįor the labor that we had already put into the project. These were customer-supplied, so as much as Much we can do in a situation like that other than return the boards to Wouldn't be an issue at all except that the hole size was just a Take one job that had several hundred through-hole resistors.

We sometimes get boards with a lot or even nothing but through-hole. Most of what we do is machine SMT work,īut many boards have one or two through-hole parts as well.
