Try sliding a standard plastic trash can liner in and out of the can a few times, then crumble up a few styrofoam (polystyrene) packing peanuts and dump the bits in. You'll be lucky if any of the bits even reach the bottom, unless it's an ESD safe re

Hi all, We have been trying to improve our current levels of ESD control in our SMT manufacturing area, while carrying out a initial audit I have found that we have two different grounding planes. One for the electrical grounding through mains powe

The problems we saw had to due with the Flux I believe. We saw what I would call poor coelescence and the residues were very hard for us to clean with our Water only cleaner. I will not lie and say I worked on the process very much. Since we alrea

Thanks pr I know what you mean, and just to let you know, you can turn the over head one off and get one for the center nest. Will be more than glad to tell you how to turn off and turn the center nest one on. And just to tell every one else, were

Rob is right on with the comments above. As I believe it is pointed out, check out Mydata and also Assembleon. In fact, in helping others like you I have found Assembleon to strike the better deal even over Mydata. You can teach parts and boards wit

Hi. In the past years I had made dozens of PCBs but now I am trying to get a professional finishing on them. The main problem is oxidation of the copper traces. Basically I use the silkscreen method to make the pattern in both layers and then etch. L

guys, I am having a problem. During my rework (SRT) process, I am trying to reach a board temp of 150degC b4 the top heater comes down for the actual rework process. Due to which the flux (tacflux 20)is burning off and i am seeing lot of non wetting

If no-clean...then this seems "relatively" normal. You could try and extend your peak and duration, however, manufacturers are adjusting their chemistry to survive these normal temperatures (up to 260C and 30 seconds within 5C of peak). You will h

Thanks for the comments everyone. I did not think of checking the nozzles material, I will check this out. GS, What is PBM, is this some sort of ironiser. Also to clarify, we believe the that the pocket size for the component is too big allowing th

Guys I do not know what you guys are trying to prove. If you have a BGA job to be done JUST forget about using any equipment that is using hot air since you will get into a lot of trouble. It will bend the PCB and need nozzole for each IC find an ER
