Thanks for that. It's definitely a tricky one, with lots of yet to be confirmed exemptions. It's particularly confusing with this type of product as it is said to be up for exemption due to lead in the glass of the erase window. However, does this

Does anyone have a list of SMT components with their weights? For instance, a PLCC64 pin = X grams. I am not even sure if such information is really valid but it would be interesting to know when developing a reflow profile for convection ovens on a

We had the exact same problem on our OMNI 10. We found that two of the rails the pin chain rides in were warped. Somehow at one point our PC lost communication with the oven and the heaters went wide open for several minutes...this is what caused th
