Steve, I have done BGA work with and with-out Xray. If you are going to install them in high volume it makes sence to have every thing including rework on site. If you are just going to put down several a week you can probably get away without th

Jim, Thank you for the input. Could you please check your standard filter pore size? A model number would be valuable. How many shop volumes (in cubic meters) do you pump per hour? Customer is seriously thinking over installing AC system similar to
