Hi! I have a very basic question about PCB cleaning. Which is the best way to clean the PCB after soldering? We use a lead free solder wire (3,5% flux inside the core) and after the soldering its a visible wetting,flux around the joint. When using th

Hi, Based on our experience, you can collect X-Ray analysis of solder joints and calculate values of SPC (such as PP/PPK and GR&R). Now, you can find, based on this calculated values, if your production is good or not. Also, this helps you to detect

Dale, Be very careful about putting to much grease into this actuator. It is kind of a sealed unit. If you were to take this actuator apart you would see that the motor drives a heavy pitched threaded screw. As it turns it causes the threaded tube

We're currently using no-clean flux (SR-12) in a no-clean manual soldering process. The brownish flux residue impedes direct visual inspection of the solder joints. Therefore, we're forced to clean the residue off. (1) Is there testing we can do

On the flux reside issue that is gumming up your test probe pogos ... Short term, clean what's in process with a aerosol flux cleaner solvent. Ask your flux supplier for recommendations. Longer term, recognizing that there is no fix, your improveme

I have a supplier that want to upgrade all nails on a huge amount of ICT fixture due to test RoHS compliant PCBAs. My thought is that even if there are a very small fraction of residues left on the pins it will never go over the 1000PPM level. In fu

I can't believe there is a topic for discussion. Find a way and measure lead contamination(if any)and prove them wrong. This is getting out of control. Having all the billions of gasoline and diesel engines pumping dirt in the air, together with the

We are trying to build two different PCBs - one with no wash flux solder paste and the other with a washable flux solder paste. How difficult is it to use the same SMT line and switch between the two pastes? I assume there will be some cleaning invol
