We've had the same issue on our Panasonic CM machines with Cree XP type LEDs. Count on tools makes a urethane tip nozzle that we are using which eliminates the sticking, our concern with these is durability. Nozzle supply company makes a steel Teflo

I am looking for IPC or other published standards that specify cleanliness levels for: 1) solder paste stencils 2) selective solder pallets When we cleaned PCB's we used a limit of 4 M-ohms. Now that we have transitioned to No-Clean, I am wonderi

we encounter the same problem as you 3 years ago. but now we have implement to use KIC 24/7. you just need to take 1 time profile (for the base line profile), and then for the next time you run your product, it will take profile for each board you b

KIC 24/7 has evolved into RPI. Not only will it give you virtual profiles, it also gives you DPMO and yield, based where each board lands in the process window. The good thing about this software, you can go back a year later and look up a specific

Thanks for the information and insights. Our booster is probably getting too hot, even with AC. There is bouncing when we trim component locations. Every so often, while trimming component locations, the x-axis will start to slowly move away (by i

Just my two cents, but when we invest in capital equipment, we look for an ROI of 2 years or less. This is our benchmark. One of the posters is correct though about factoring in insurance and other benefits into the hourly wage. We use 1.5 X hourly

We clean (using a pencil eraser) the fiducials on all our PCBs before processing them through a QUAD QSP-2. We're discussing pcb's with our fabricator to see if they have recommendations. Some of our Engineers believe it is the QUAD that's the proble

We only clean ones that are rejected (typically 1 out of 250 or more). Very well could be an issue with the boards supplier if your having a inconsistency in plating/hasl process, under a scope do the fiducials look the same between boards? More like

I clean all fids with a fiberglass brush pencil so that I know there will be no rejects (it doesn't take too long). The problem is the machine lighting. My Essemtec machine uses a light ring (red LEDs) around the cam. Here's one of many documents th
