Hello, I am new to the SMT area and I need to know what a "good" vapor phase reflow profile should look like. The fluids we are using have a BP of 45 C and 219 C. Thanks,

I have been actively experimenting with Selective WS pallets fabricated from Delmat. I need feedback from users on life expectancy, demesion constraints relative to warpage or degradation, and any useful info on ways to maximize life and prevention

A Tips window appears everytime I visit the Forum, even though I have checked the box to insure that it doesn't reappear on the next visit! Why? Doug

We are having a continuing problem with 0603 chip capacitors not centering themselves on the pads during the reflow process, causing an open condition at one end. Does anyone know what can be done to alleviate this? Thanks much. Gary

Gary, We've experienced the same problem in the past, and found that moving the stencil apertures closer together solved the dilemma. This was a much easier solution than having to redesign the PWB. Leland

I have read in some magazine articles that there is poor signal to noise ratio of RF devices when no-cean solder is used. The frequecies used exceed one Mhz? Is this true?

Some under-the-hood automotive people have moved from no-clean to clean, and I mean CLEAN, recently. Hmmmm Dave F

Do I have to tin gold lead devices? Can I use indium? Can I use lead-free Can I use tin-free

Michael, IMP Printed Circuits in Adelaide ( Australia) have an old XY table / Digitiser head system that just needs a Maher controller to get it up and running. Their email is imppcb@codan.com.au attention Bob Armstrong. Regards Richard
