we have a static problem with 0603 led when removing the plastic retainer from the tape and reel. same problem with the feeder causing reject and bad placement. is there someone having the same problem? and how to fix it. thank you

I have read in some magazine articles that there is poor signal to noise ratio of RF devices when no-cean solder is used. The frequecies used exceed one Mhz? Is this true?

Thank you guys for your help, I do not clean any on my assemblies who are build by the SMT an wave soldering department, we do used liquid fluxes Kester 951 and cored wire keester 245, usually it�s for batteries connector, led, terminal and wire rap

Some under-the-hood automotive people have moved from no-clean to clean, and I mean CLEAN, recently. Hmmmm Dave F

Hi Jeff Actually it's not necessarily Signal to Noise Ratio or even RF circuitry. All no cleans leave behind residue by description. This residue can affect RF or other high frequency circuits in a number of different ways including SNR. Very high

Now an than I hear, read about the same thing but without mentioning specific frequencies. It�s something that worries me in the back of my mind but not in actual daily workflow. Our boards go up to 50Mhz with digital bus systems and are made with no

Anyone using a No-clean solder paste on a pcb with a 100 Mbps Ethernet chip? Will the residue cause any signal degradation? Any issues with a no-clean solder paste and 1000 Mbps Gigabit Ethernet? Device: National Semiconductor DP83848 10/100 Mb

Residues from different no-clean fluxes produce different levels of variation in RF circuits. Some no-clean fluxes work fine. Following this, a no-clean flux can produce different levels of variation in RF circuits depending on the process setup.
