All, I purchased a CoolCap kit to help protect components during BGA rework and it appears to work fairly well. The shielding devices are fragile. Cost is $400. Here is where I purchased the kit from: Cookson Electronics (800) 367-5460 www.alphametals.com Best Regards, - Joe -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Kane, Joseph E (US SSA) Sent: Monday, April 23, 2007 2:25 PM To: [log in to unmask] Subject: [TN] Cool Caps I seem to remember that Alpha/Cookson was developing some small covers, sized to fit over various components, to protect them from secondary reflow. I believe that they were called "Cool Caps", but Google and the archives here turned up nothing...
