Yeah, you'll get the blue button functionality w/ 1.6. That protects the machine by disabling the magazine before its pulled from the machine. It tells the computer not to pick from that mag. Going from 1.4.7 is the same as going from 1.5, just softw

4.4 Determine the amount of flux on the board. 4.4.1 Get a piece of corrugated cardboard and a weighing scale accurate to 0.01 grams. NOTE: Use cardboard with alcohol fluxes to slow their evaporation and get good data. 4.4.2 Weigh the cardboard. 4.4

I agree with the two other replies. Left alone, it is a defect. If it's just excess adhesive or coating, you can use IPC-7711/7721 'Rework, Modification and Repair of Electronic Assemblies' for guidance on removing. Section 2.3.1 explains how to te

basically the rule of thumb for the 8mm feeder is that you only want one component exposed in the pocket at a time. If you see more than one component exposed you need to go down in size. The reason for this is that if there is another component expo

Hi everyone. I am now faced with a problem on soldering PBGA. At first, I ran the board (FR4, 7" X 10" with 12 layer) at Peak Temp: 205 C and 54 seconds above 183 C. After reflow, I found several cold solder joints and one ball without second collaps

Hi, I'd be inclined to go with the through hole capacitor, as to surface mount it you would probably need to go for an elco (ceramics & films don't do that value in that voltage, & you'd be hard pressed to get a tant in that voltage). SMD Elcos a

We had a customer that had 5 BGA's top and 2 bottom and several other assemblies that had 4-7 total BGA's that required WS. Our average build quantity was 2200 boards a month. We used high end Maytag dishwashers and a little Amterge(SP?) Took them t

If the pendulum is motor driven, it's more likely that a capacitor change will accomplish what you want than a resistor change. You've got a 47uF in there...try a factor of 10, and put a 4.7uF in there and see what happens. If the pendulum period i
