I would probably go with the Assembleon. It is a very well built machine with good software. I don't know Ipulse, but I've worked on the other 2. The newer cheaper machines could have problems. With potential down time, the difference could pay f

Hi, all of them are good machines. The others talked more about ass and mydata. I-pulse is also a good machine. A friend of mine bought one 6 months and is happy with it. Just not sure about the model. Did you send them a board? You should do that

The pad size is okay. I have also requested the manufacturer's recommend reflow profile. I have seen some issues with 0402 caps that we run also but for the most part solder paste does okay. I think the cap issues is stencil related. Still trying to

Hello Mark, I would recommend to look again on the pads. in many cases board design is causing these issues. Check 1. Is pad size good for the part 2. Are both pads the same size 3. traces connected to the pads should be same size 4. vias connecte

I am a PCB Designer and I have to put a note on the assembly drawing to tell the assembler how to clean the board. This is new to me. Here is a sample note. Can someone give me some feedback on it? "Use water washable, no clean solder paste for t

Water will not remove no clean flux residues because they are not water soluble. Solder paste with no clean flux should only be used when the assemblies do not need to be cleaned. That said, you can buy special cleaning solvents specifically for re

Dont Peace Out... You do offer valuble info. Most people on here do. I have learned a decent amount of info off of old timers and people with experience. Maybe it was removed by accident or perhaps you released a "Trade Secret" the mediators dont

I do not know if you want selective wave soldering or selective point soldering? If you have good budget say, less than US$200k Vitronics is best for wave selective soldering. However, if you have low budget say less than US$100K I suggest ACE or K

Hi There are many ways of doing this but I usually transpose the coordinates to the lower right hand corner of the sub-panel that is situated at the lower right hand corner, because the reference point of the machine is the right hand side locate pi

Let�s say I want to increase the shear strength of a solder joint. Does a lot of solder around a joint create more strength? Why not just absolutely bury the component lead in solder. My initial thought is that it doesn�t increase strength, but I don
