The pick n place height for component was set to 1.4mm but I had not allowed for pin thickness. I added this (total height now 1.6mm) and I get very few solder bridges now. I might try 1.7 and see if it makes any further differnce

Normally if the package is defined properly I would expect your machine to place it correctly but we have some parts pushed right down to the pads. If the paste is centered, and the parts are centered, and you have obvious bridging potential coming

Hello All, we have 2 CP842 on site and they are running simply perfect. We used our existing CP feeders (with the small reel holder). CP843 can compensate pick-up both in X and Y direction. also measuring the height of the part with a laser sensor.

I have seen this problem on Mydata machines before. I am very sure that your missing paste is being caused by the placement machine. Check these things : 1. There is a small white check valve on the pressure side of the vacuum pump. Make sure it is

Now knowing that its a Quad, I'm assuming it has QuadAlign which spins the part it just picked in a beam of light and a sensor measures the length, width and height of each part. If it falls outside of a defined range, it will throw it in the dump bi

SOLVED Upon manually activating the zaxis to drive the spindles down, it was noted that the touch down sensor for spindle #2 was activating at a certain point in the travel without touching anything. I went to look at the adjustment of the sensor

Since I have posted on this last, we have found that 99% of our nozzle sticking problems are do to part height problems. I have been told that CP6 machines are very sensitive to part height do to the amount of spring travel in the nozzle. If you hav

FYI SME offers a replacement Tape leaf detection system which covers the whole range of FUJI CP4-CP7 machines.its also very reasonably priced. It doesn't use Fibre Sensors or mirrors. it only has 1 adjustment which is height via Eccentric screw. even

WOW Sr.Tech, 40K worth of bent tools? I'm about ready to be sh*t canned because of 1K's worth. As for trimming the mags, the product is running fine (many boards) and then out of nowhere the tool bends, so I assume my PERFECT operators trimmed the ma

Yukim, Just another thought (way off the solder paste trail that you've been on so far)....Are the parts similar in thickness? The 4796 and 4797 HSP's have a closed loop function that compensates for variations in component thickness based on fe
