Subject: Codes and Standards
Would someone please bring me up to date on the status of the Reliability and Maintainability Standards. I need to know what is being used in specifications in lieu of Mil-Std
785, 781 and 470 and 471. Thanks if anybody can steer me to the latest update on that I would appreciate it.

Subject: Solder of leads on low power VCSEL laser diodes
Hand soldering of 0.019 dia VCSEL laser diode pins (usually in TO-46 packages)to solder pads on small PC boards is a common practice. Some laser diode manufacturers however advise against this method and recommend using connectors, while others provide solderability specs. I am interested in hearing from anyone on laser diode reliability issues related to the use of hand soldering, and also any ESD damage observed due to this method. Thank you.

Subject: HALT on Controllers
Does any body have experience on conduction HALT on controllers (electronic control units used on automotives and construction equipment)? What stresses are used? How to monitor the functions of controller and how to detect the failure?
