I have programmed one of each. The rules-based machine is about 6 years older than the model-based system, so It's probably not a fair comparison, but I prefer the model-based system by far. The model-based machine gives you a lot more flexibility an

Which companies are you talking about? There are now 2 that have left the industry... Orbotec announced a couple of months ago and Agilent was announced today on evertiq.com With that said, We have been using the Yestech AOI systems for a while now

Hello everybody, We are running a product through wave solder process using three different PCB suppliers. I have noticed that you can see more flux residues (water-based, No-clean flux) on one supplier than on the other two. All three PCBs run unde

Hi George, I would suggest you to re-look your process parameters, especially for the pre-heat temperatures and the amount of flux deposited. The mask properties and that of your flux also play a role, but you could zero down to the root cause after

Build in some flexibility to your costing. You will want to take into account how long various activities take and you will have to have your people do them in order to find out how long they take. In the end you will have to do your own costing bec

Thanks for your reply Stephen, I don't have any idea of how CM's are currently pricing out their work. I don't want to undercut anyone, I just want to make sure I'm not too far over that I'm out of the market. Or, too far under and selling myself s

I agree, I'd try placing them with the midas or z-fi head depending what you have. Try using the mechanical centering in the zero angle with a low strength to move it straight. You'll probably have better luck finding a tool that will work on the hea

Hi First of all you have to respect the dwell time and the time after the reflow at peak tmeperature.(225�C for Pb and 235�C for Pbf) You can find the reflow profile from manufacturer for majority of parts designed for reflow sodlering. In general t

The problem expressed by you need not necessarily be caused by the Reflow process even though it's effect cannot be ruled out. I suggest to validate periodically the Reflow Oven performance as also optimise Reflow parameters through a documented vali

Smartasp, Seems this issue is certainly making a long thread ! As far as our Experience is concerned on Reflow Soldering, particular parts must have failed in LSLs [Lower Specification Limit] and have not withstand well under USLs [Upper Specificat
