gold, one of the stablest elements on the periodic table oxidising. Are you sure, and why would you want to reduce the vision fail rate on a part that is clearly shockingly poor?

On machines such as MyDatas you have the ability to mechanically center parts rather than optically centering. If your machine is capable of doing mechanical centering that would eliminate the need for the vision analysis. -Joe

Thanks Joe. I will check through this with machine supplier to understand what's their machine's ability of doing this.

The presence of agitation at an air / solution interface and a foaming agent causes foaming. Most water soluble fluxes contain surficants. Surficants are foaming agents. First, it's likely this foaming is caused by poor control of the temperature of

Our land patterns are slightly bigger than the part, we've had no problems. There are your own concerns about the part hanging over the pads, this can be ok or not depending on your application and/or how much part is over. I'm sure this is in the J-

If you have a virus protection software in place it is likely slowing your system down to a crawl. Disable it and see if your results are better. You can also do a ctrl+alt+del. Go to "Processes" and take a look at what is bringing down your speed. H

Setting Speed for Ram is usually in the BIOS set up, Pressing DEL key, or F1, or ESC should bring you into the screen. It will usualy tell you on boot up. Look in there for the setting. Other times its a jumper setting on the motherboard. 7200 & 1

SMT fine pitch connector having oxidation on lead and P&P machine keep rejecting the part. Is there any alternative way to reduce the part throw out rate without jeopardize the placement accuracy? Or is it possible to re-coat the connector lead or an

Hi Joe, first of all thanks for your input. I did tried to search for the Mydata brochure and found that they are using Lifescan Vision System (LVS) which i think should be vision analysis. Appreciate if you can explain more in detail how's the mecha
