Richard, Please contact me on my corporate e-mail to let me know about your opinion these standards -----Original Message----- From: Lee Whiteman [mailto:[log in to unmask]] Sent: Monday, February 04, 2002 9:01 AM To: [log in to unmask] Subject: Re: [TN] Proving the reliability of a solder joint Richard van Beveren, You may want to consider the following test methods to determine solder joint reliability: Vibration: JESD22-B103-A Vibration, Variable Frequency MIL-STD 883; Test Methods 2005.2, 2006.1, 2007.2 Thermal Cycling: JESD22-A104-A Temperature Cycling MIL-STD 883; Test Method 1010.7 The big thing is to determine the environment that the assembly will experience during its lifetime, and develop an appropriate test. For example, in certain aerospace applications, thermal cycling is performed from -55C to 125C. These limits might be too severe for a commercial applications. Hope this helps. Good Luck.
