Cant put a finger on it being an encoder that was just a single possibility. You can always hook up a scope to the encoder and see if they are working appropriately. I would look through the machine's utilities and see if there is some debug or more

When you say, "you can see the plating of each lead embedded in the broken solder joint", we do not get the sense of a well soldered connection. * We don't expect to see [or make the distinction] of the plating from the connector in the solder. We

There is a couple of things to check. Put the machine in diagnostics and let the chain run. You should see it run the same as you would if purging it. Sometimes the 2 hall effects at the disk do not see the disk as it turns. Check the driver board

I would like to know what you are seeing in production. I have read the papers that state fewer tombstones with SAC305 as well as the papers that state more tombstones with SAC305. I am seeing more tombstones with SAC305. I place a lot of 0402 com

Good question Dave. Kerry has participated quite a bit in this sort of forum but I have yet to hear whether he is a user or a critic. Check out the Apex exhibitors manual to see all of the vendors that are available or the archives on SMTnet. You

Hi Folks, Well, what I want to see is below: China is good in imitating products. They imitate but they sacrifice the quality. When can I see a Pick-and-place machine that is MADE IN CHINA? With most manufacturers shifting to China....that dream wo

If you have a specification for the flux, you can retest all the parameters to see if they still comply. Check with Alpha to see if they have a recommendation. Our adhesive suppliers recommend running a lapshear to recertify, so the flux manufactur
