Rather than rely on either an expensive sub-contract cleaner or 'elbow grease' try somewhere in the middle. But a standard dish washer, we did and it works perfectly.

Soltec will come in and train people at your facility, or you could send people to their facility. I found it pretty useful in a previous life.

You may want to try C8502 from Kyzen Corp. I use it on our three wave solder machines with great results diluted in DI water 50%. I am an end-user like you not a sales person! You can order free samples... -George

Hot tear occurs at the surface of the solder connection. The surface will look like someone tore the surface apart. So, it is a crack or fracture formed prior to metal solidification.

Are there tantalums close to these SOT's? Could be related to a previous thread on moving components in reflow oven. http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=11279&#Message46732 Steve.

This question maybe more for myself than SWAG, but, could this be a DELTA problem caused by design? (Ground Plane) One side of the component reflows later causing the component to twist???

easiest way is to weigh an empty board and then weigh a printed board, best to do 10 or so and take an average.

Here's a good thread on lead free reflow recipes http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=47575

We do it on a regular base. You can check out the website below (we are still working on it, though). Regards, Vlad www.sentec.ca
