They key requirement before any fancy tools is careful storage, stock control, labeling and handling. If your parts are incorrect before they even get to production, you're screwed. As gregp suggests, to get consistently correct value and orientation

I have had some custom support jigs made but as i'm working for a contract electronics manufacturer there are so many different PCB assemblies to be made - storage of the different jigs and the changeover time is the problem. The support system ne

Does anyone have any experience with using padded static bags to minimize damage to boards during handling and storage? Does anyone recommend a specific brand or type?

Suggestions are: * Procure solderable finishes that have sufficient thickness to avoid intermetallic problems and use storage conditions that do not promote oxide growth problems. * Bagging/sealing boards has been shown to extend storage durations i

Ideal storage conditions to stop pcbs absorbing moisture is at less then 5% RH, for example in sealed moisture barrier bags. You mention that storage was at 40~70%...at these levels the pcb will absorb quite a bit of moisture. Your baking time was no

I am not intimately familiar with every resource available in our stores, but I don't believe we currently use or own any dessicant storage cabinets. MSD's, LF or not, are stored in sealed Moisture Barrier Bags with dessicant.

Q1 Are there any standard regulating the subject? Very few infos found on IPC. A1 We�re unaware of standards for packing and storage for most types of boards. * IPC 4553 standard for Immersion Silver Finish, 3.8 Packing and Storage. * J-STD-033 and E

It seems there isn't right connection between solder and solder-legs. Maybe check that the LEDs get huminidity, have some oxidation on the legs, try different solder paste, check the reflow solder profile. On the photo I can not saw properly reflowe

Praveen, Once you find out the MS level of your components, you will need to track the exposure time from when the parts are initially removed from their dry bags, through test, programming, taping, and during subsequent dry storage and use of thes
