Suggest looking at the packaging,is it sufficient to prevent damage to the QFP?. What way are these components stored when received?.Are the reels stored in boxes or racks?.Storage in boxes may cause damage from stacking the reels on top of each oth

I feel your pain. Your company may already be using Kapton tape labels for their board serial numbers labels. Kapton is able to withstand repeated wash and heat cycles, and can be printed on a typical Zebra printer. The key to a successful and accura

I'm a Production Supervisor in a food plant in California. I'm looking for the same training video I once saw. It is very short and sweet and right to the point and opens the eyes and minds of the workers. If you find it please tell me where you foun

Hi, I am planning to evaluate and qualify solder paste that we never used before. What are the test data that I need to request from the paste manufacturer for our QA prior to evaluation? And is there anything that you could provide me such as ideas

Besides the processing tests (different print speeds, print delay times, etc.) one test we've had to use is humidity exposure. Solderballing due to high outside humidity is a problem in our plant. So we expose paste to 85% humidity for various time

Has anyone seen information on the Reflow Reflow soldering method, without using glue? Currently run a Fuji 241 XP and Ecra Paster, however we do not have the glue attachments for double sided boards. I've heard double sided boards can be reflowed

Due to some reason there are few balls of the BGA left open during the process. Reflow profile has been verified. There are other BGAs on the PCB and they are fine too. The BGA in question has a very large metal heat sink on top of it and is placed r

thanks for your reply ....yes the air is then able to hold more water vapour.... but so is the component hence there is no water vapour pressure difference and the component and the air in the oven would still be in equilibrium???? hence no effective

Hi Chris, Acually, it worked pretty good. We made a new blade from SS. We were not sure if it would work so we diddn't want to commit a good sqeegee blade. You will want to try to keep the cutaway toward the center of the blade. And don't hit the fl

We have this machine and I would be surprised if it really took all two hours for training. The machine is very easy to operate. I don't believe that Glenbrook provides "inspection" training if that is what you were thinking. We love it and it do
