You'd have more luck looking at where it is located in the circuit than posting a picture a of brown brick with contacts either end. Its fairly chunky so sure it could be a ferrite of some kind (but they are normally black) or indeed a Fuse, self re

Our company is looking to upgrade from a dek249 semi-auto printer to an automatic inline printer since we're doing some fine pitch packages which are tricky to line up, and we'll soon be tackling bga's for our products. We're looking on the used mark

Both are good printers, the key thing buying kit this old is availability of spares and support - Check out what is available local to you. We have 14 DEKs, which we are happy with - but the support in one of our regions is fantastic (local independ

I see your point and I know you can make this machines run, but it doesn't change the fact that when you need them most they will let you down. It is almost impossible to find spare parts for some of them, as they are no longer supported. If you have

On a previous black pad experience we soldered a wire to a fiducial and did a pull test to failure. On the black pad board the wire and solder pulled of clean leaving the fiducial on the board. On good boards the copper came off with the wire. If you

I'd guess that "black pad" is not the issue that you need to address, because only 2 of your 5 test points has the problem that we seem to be discussing. I'd expect "black pad" problems to be more wide spread. Something is going on at those two locat

Hello, Does anyone know where I can find any information or documentation on the miniwave height sensor and control. I feel like the company I'm working for is possibly using the machine incorrectly in this regard. I assume, but would like to verify

My company uses both Juki electric and mechanical feeders. Yes, electric feeders are much more efficient than mechanical as far as pick speed and general feed speed. However, if a reel runs out, it usually takes our operators under a minute to change
