Hello all, I am having some trouble with the conveyor speed on an Omniflow 7 reflow oven. Recent profiling showed that the conveyor was running to slow so I calibrated the speed using the instructions in the manual. After calibration there was no ch

Pallet angle is usually pretty good. Lead length is also another good thing to keep as short as possible. Air Knives don't work that well. Also check your board. Make sure you have solder resist between each and every thru-hole pad. If the board

Here in the Great White North, the best way to check our CM's compliance with the ESD 20.20 is to take a couple months worth of data during heating season and graph it against the outside temp swings. You can easily see how the HVAC system keeps up,

i would say that you are there already. with 10,000 DPM0 you have a 1% fallout, you are at 99.9 basically. 1 out of a 1000 boards will fail? of course one thing we need to know is how many opportunitites do you count for a chip resistor for exam

The use of booties isn't required per se, just considered a standard step necessary to reach the 10,000 target. You also need to vacuum (central vac system, NOT exhausting into the room) daily, mop weekly, have a one piece floor, blah, blah, blah....

Total Force is the weight on the squeegee blades. Generally you should set this by the length of blade you use. A 12 sgeegee blade would require a Total Force setting of 12 pounds. So, if you have 8 inch long squeegees, you should be OK. Your b

You are probably using a GSM since you mentioned "enhanced board setup". 1.- Your CAD data. It works better when all your data uses bottom left of the PCB as a board origin ( BO ). If my CAD does not use bottom left as a BO, then I edit the data in
