We have a customer with an assembly that will require potting using 3M DP-270. There is a component that needs to be covered with potting material but it is considerably higher than the overall potting height of the cavity. The low viscosity of the

If you want a step by step guide on BGA look at my NPL/IPC "Defect of the Month" video clips https://www.youtube.com/watch?v=MC4K0eSXH18 For other process issues there are also videos which may assist on other process issues like voids, solder ball

Couple things: If the rubber roller that touches the take up wheels is worn you can adjust it. The axle is on an eccentric. Make sure the "teddy bear faces" that adjust the pick point are not grossly different from the left to right sides of the ma

I assume you are running Lead paste and that is why your parts are moving during reflow. Most probably these caps have leads that are bended in random directions(look at some parts from the bottom and observe how symmetrical the leads are). In additi

We see this from time to time. Usually, one of the leads of an electrolytic is attached to a ground plane, and the other to a trace. The ground plane acts as a big heat sink and reflows significantly later than the trace. If you have glue in your li

Thanks Sarason, I will take a look at your software ASAP. In the meantime, I've been able to answer my own question. Feeders can be associated to components by using the same component name in both tables. It's very simple in fact. These TWS Quadra

Ahh, yes. Just about the same time you replied someone else I asked said the same thing! I didn't realize that you had to put the part on by hand for the vision test. In the book it says to leave the feeder position set to the default setting. Fu

You should be fine! best practice for a situation like this would be to run a solder sample, either flux it and run through wave, or screen print, don't place parts and run through reflow. look for proper wetting characteristics if you see de-wetting

Hi, that's how it works: 1. Zoom to the object you want to start with. 2. Click S to center to the object. Depending on the zoom you can center to pad, line, corner.... 3. Click Z(this zeroes your Relative coordinates). If you click Ctrl+z(this ze

I'm no clock expert, but, even that unit you linked appears to have the period set by the weight on the pendulum. That unit notes that the pendulum is adjustable....though, I'm not sure how/what is adjustable...I would expect it to be the weight. I
