I have always thought it to be a good practice to wash SMA's with water soluble paste (WS609) soon after reflow. Is there a time limit as to how long a board should sit after reflow before washing said board? For instance; processing a double-sided

Is it possible to place parts that do not have leadframes exposed when looking from the top side of the part such as BGA's using a Fuji IP1 with a SMD1 vision (Binary) system. I realize that the IP1 does not have front lighting but according to a Fuj

I discovered that we have some gold plated (30 mico in.) through hole connectors which were Paste In Hole soldered (60 sec at reflow) on a HASL PCB. Do we have an embrittlement reliability issue? The calculated volume % of gold in the joints is about

Does anyone have a suggestion for a UV resistant black potting material? The material recommended by a local vendor turned gray in a couple of months in the sun here in Florida. We are using L.E.D.'s in a small housing (about 1.2" cube) and need to s
