| We are getting into a lot of double sided boards offlate. Our customer is loading a lot of RNETS, Diodes ( MINLS, SOT23s and other 2 leaded diodes ). We are processing it through a traditional glue process and wave soldering the SMT parts along wit

Hi Jason! I can probably find something documented for you, but the easiest way to convince your QA people is just to show them. If you have a board around that has some 1206 locations all in a row, print the board with paste and then plac

Well grant just to let you know i feel your pain. I've been wavesoldering with sn100c since January and let's say i'm still learning everyday. Some of the typical causes of bridges are not enough flux when the board hits the solder. Also it can be bo
