Does anyone have any figures on visual fail / no pick? our machine records this but no one has been recording the machine and it's been running since we've had it (a good few years). I am currently assuming it's about 0.2/0.3% but this is a (not very

Hello, I would like to ask for cooments/advices about the inspection of small solder deposits inspection (aprox 4 mills). We tried with X ray and Scanning acoustic microscope but it looks like due to the small size, we could not be sure to get all t

To answer the first post after my initial response we haven't published any of our lead free data since it is proprietary, sorry. As for the nitrogen cabinet it has been proven that over time the Gold plating can build up a layer of oxides that can

We are investigating a system, using 2-D matrix code, that will identify and track every PCB throughout our factory, starting from bare board. As a low-medium volume manufacturer, would labels or laser marking be more cost-effective? How difficult is

KH This won't work if your planning on running these 2 machines together in line. The fast machine will always be waiting on the slow machine. How many Philips FCM's have you seen in line with Mydata? Don't think to hard; the answer is zero. Wh

Well Dave, Check the number that is on your adhesive tube. They make several different types of adhesives for use on different substrates. The rep from Dymax recommended the 3073 for bonding to FR4. We use a Dymax HHL400 handheld curing light. Click
