Hi Bill, You should contact your local water work dept. and work with them. Every county is different. Sometimes it not what you put in the drain, but how much. They may want to monitor your drain, which is standard stuff. Be prepared to show th

Hi, We use 1:1 for 1 mm BGA and it works fine. We used it at 4 thou laser cut stencils when we had a manual stencil printer, but have moved to 5 thou with the DEK and it works ok. We originally went to 4 thou because of paste release, but the DEK

This sounds like a form of corrosion called electromigration. It creates cathode anodic filaments. They have a fern like shape because it is a metallic based crystal structure. Electromigration requires: * Difference of electrical potential * Chemica

I ran into an error with our DEK 288 machine, when I go to initialize the machine the following error occurs: Squeegee Height: Error Input Active. This occurs with or without a squeegee present, and I have tried restarting multiple times, but the sa

I have to disagree with you SWAG. Unless you thread it, it doesn't meet fire code. If you got connections that operators plug into, copper bends easy compared to other pipe. PVC is only allowed for compressed air if it is used underground (at leas

We're using the 1B73LOC conformal coating from Humiseal. We've seen some bubbling of the coating. Their tech handbook suggested reducing our oven ramp speed. Does anyone have a good profile for this? They've always pointed me to Nordson, and Nord

Hi we have a Universal GSM 1 flex head machine. It keeps on bringing up an "Axis Head 1 Z velocity over speed error during move absolute command". Pushing the e-stop button and then start again will allow it to continue making the panel. It happens r

I have encountered poorly designed BGA packages that cannot be removed or replaced with BGA rework tools. I discussed this with the package designer. He recommended reflowing the entire board. I was finally able to remove the part by preheating the

Hello all, I have a question in regards to part tolerance on parts. I called Fuji (not doubting them at all here just looking for more insight here) and asked them what the usual % tolerance on parts is. They came back with 30% of a part and the tole

Interesting, thanks for the info. All that I know right now is that running the jaws through an "el-cheapo" demagnetizer was one of the actions taken that resulted in a reduction of missing components. It is possible that this is not a dominant fac
