Stick a label on the package with the initial opening time and date & the use by time, then check before using again. Use the disposable indicator cards - if the are attached top the waffle packs they are getting the same exposure. Get your supplie

Hi Ken, You're right - they're not doing anything smart, they are just using a rechargable battery pack. It's not even the latest or most suitable technology for the application (Li-ion has far better temperature characteristics & far high capacity

Leader tape on partial reels

The leader tape from Sierra works good for us. But if you have to work only with small strips and you can't affort to lose any parts think of moving them into waffle packs. It depends though if your machine has a tray for that. Regards, Cristina

Do yo have to bake unused bare boards or just Vacuum Pack?

Baking MSDs in tubes?

Electronics Forum | Mon Mar 05 10:30:28 EST 2007 | Rob
